TY - JOUR A1 - Hohenstein, Sven A1 - Kliegl, Reinhold T1 - Semantic preview benefit during reading JF - Journal of experimental psychology : Learning, memory, and cognition N2 - Word features in parafoveal vision influence eye movements during reading. The question of whether readers extract semantic information from parafoveal words was studied in 3 experiments by using a gaze-contingent display change technique. Subjects read German sentences containing 1 of several preview words that were replaced by a target word during the saccade to the preview (boundary paradigm). In the 1st experiment the preview word was semantically related or unrelated to the target. Fixation durations on the target were shorter for semantically related than unrelated previews, consistent with a semantic preview benefit. In the 2nd experiment, half the sentences were presented following the rules of German spelling (i.e., previews and targets were printed with an initial capital letter), and the other half were presented completely in lowercase. A semantic preview benefit was obtained under both conditions. In the 3rd experiment, we introduced 2 further preview conditions, an identical word and a pronounceable nonword, while also manipulating the text contrast. Whereas the contrast had negligible effects, fixation durations on the target were reliably different for all 4 types of preview. Semantic preview benefits were greater for pretarget fixations closer to the boundary (large preview space) and, although not as consistently, for long pretarget fixation durations (long preview time). The results constrain theoretical proposals about eye movement control in reading.

Verschiedene Studien zeigen bei erwachsenen Patienten gravierende Auffälligkeiten in den kognitiven Funktionen. Dahingegen scheinen bei adoleszenten Patienten lediglich leichtere Einschränkungen in den kognitiven Funktionen vorzuliegen. Die Prävalenz der Anorexia nervosa und unipolaren Affektiven Störung ist mit Beginn der Adoleszenz deutlich erhöht. Es ist anzunehmen, dass kognitive Dysfunktionen, die sich bereits in diesem Alter abzeichnen, den weiteren Krankheitsverlauf bis in das Erwachsenenalter, die Behandlungsergebnisse und die Prognose maßgeblich beeinträchtigen könnten. Zudem ist von einem höheren Chronifizierungsrisiko auszugehen. In der vorliegenden Arbeit wurden daher kognitive Funktionen bei adoleszenten Patientinnen mit Anorexia nervosa sowie Patienten mit unipolaren Affektiven Störungen untersucht. Die Überprüfung der kognitiven Funktionen bei Patientinnen mit Anorexia nervosa erfolgte vor und nach Gewichtszunahme. Weiterhin wurden zugrundeliegende biologische Mechanismen überprüft. Zudem wurde die Spezifität kognitiver Dysfunktionen für beide Störungsbilder untersucht und bei Patienten mit unipolaren Affektiven Störungen geschlechtsbezogene Unterschiede exploriert. Insgesamt gingen 47 Patientinnen mit Anorexia nervosa (mittleres Alter 16,3 + 1,6 Jahre), 39 Patienten mit unipolaren Affektiven Störungen (mittleres Alter 15,5 + 1,3 Jahre) sowie 78 Kontrollprobanden (mittleres Alter 16,5 + 1,3 Jahre) in die Untersuchung ein. Sämtliche Studienteilnehmer durchliefen eine neuropsychologische Testbatterie, bestehend aus Verfahren zur Überprüfung der kognitiven Flexibilität sowie visuellen und psychomotorischen Verarbeitungsgeschwindigkeit. Neben einem Intelligenzscreening wurden zudem das Ausmaß der depressiven Symptomatik sowie die allgemeine psychische Belastung erfasst. Die Ergebnisse legen nahe, dass bei adoleszenten Patientinnen mit Anorexia nervosa, sowohl im akut untergewichtigen Zustand als auch nach Gewichtszunahme, lediglich milde Beeinträchtigungen in den kognitiven Funktionen vorliegen. Im akut untergewichtigen Zustand offenbarten sich deutliche Zusammenhänge zwischen dem appetitregulierenden Peptid Agouti-related Protein und kognitiver Flexibilität, nicht jedoch zwischen Agouti-related Protein und visueller oder psychomotorischer Verarbeitungsgeschwindigkeit. Bei dem Vergleich von Anorexia nervosa und unipolaren Affektiven Störungen prädizierte die Zugehörigkeit zu der Patientengruppe Anorexia nervosa ein Risiko für das Vorliegen kognitiver Dysfunktionen. Es zeigte sich zudem, dass adoleszente Patienten mit unipolaren Affektiven Störungen lediglich in der psychomotorischen Verarbeitungsgeschwindigkeit tendenziell schwächere Leistungen offenbarten als gesunde Kontrollprobanden. Es ergab sich jedoch ein genereller geschlechtsbezogener Vorteil für weibliche Probanden in der visuellen und psychomotorischen Verarbeitungsgeschwindigkeit. Die vorliegenden Befunde unterstreichen die Notwendigkeit der Überprüfung kognitiver Funktionen bei adoleszenten Patienten mit Anorexia nervosa sowie unipolaren Affektiven Störungen in der klinischen Routinediagnostik. Die Patienten könnten von spezifischen Therapieprogrammen profitieren, die Beeinträchtigungen in den kognitiven Funktionen mildern bzw. präventiv behandeln. N2 - Anorexia nervosa and unipolar affective disorders are common and severe psychiatric disorders whose pathogenesis is not fully understood so far. Several studies have revealed serious impairments in cognitive functions among adult patients whereas recent research in adolescent patients shows only subtle cognitive dysfunctions. The prevalence in both disorders increases with the beginning of adolescence. Cognitive impairments that occur during adolescence may exacerbate the course of disease. Early cognitive deficits may also hinder treatment efforts and prognosis to a greater extent than during adulthood. Moreover, there is a higher risk for chronification. In the present study cognitive functions in adolescent patients with anorexia nervosa and unipolar affective disorders were examined. Cognitive functions in patients with anorexia nervosa were assessed before and after weight gain. Furthermore, the underlying biological mechanisms were explored. Moreover, the specificity for these psychiatric diagnoses as well as gender differences in patients with unipolar affective disorders were investigated. 47 patients with anorexia nervosa (mean age 16.3 + 1.6), 39 patients with unipolar affective disorders (mean age 15.5 + 1.3) and 78 healthy adolescents (mean age 16.5 + 1.3) participated in this study. Each of them completed a battery of neuropsychological tests for cognitive functions including tests for assessing cognitive flexibility as well as visual and psychomotor processing speed. Moreover, intelligence, depressive symptoms and psychological stress were explored. The findings revealed only subtle cognitive impairments in adolescent patients with anorexia nervosa, both in underweight condition and after weight gain. Besides, the results showed an association between cognitive flexibility and plasma agouti-related protein levels in female adolescent patients with acute anorexia nervosa, but not for visual or psychomotor speed and plasma agouti-related protein levels. Comparing anorexia nervosa and unipolar affective disorders, the results suggested a higher risk for cognitive dysfunctions when belonging to the anorexia nervosa group. Furthermore, the results only revealed a slightly weaker performance in psychomotor processing speed in adolescent patients with unipolar affective disorders compared to healthy adolescents. Moreover, female subjects generally displayed a better performance in visual and psychomotor processing speed. The present findings underlie the necessity of exploring cognitive functions in adolescent patients with anorexia nervosa and unipolar affective disorders within routine clinical diagnostic. Patients may benefit from specific therapy programs to reduce or prevent cognitive dysfunctions.

However, it is unclear whether this relationship extends to middle childhood. In addition, there has been much discussion about the nature of this relationship. Whereas some authors claim that ToM is needed for EF, others argue that ToM requires EF. To date, however, studies examining the longitudinal relationship between distinct sub components of EF [i.e., attention shifting, working memory (WM) updating, inhibition] and ToM in middle childhood are rare. The present study examined (1) the relationship between three EF subcomponents (attention shifting, WM updating, inhibition) and ToM in middle childhood, and (2) the longitudinal reciprocal relationships between the EF subcomponents and ToM across a 1-year period. EF and ToM measures were assessed experimentally in a sample of 1,657 children (aged 6-11 years) at time point one (t1) and 1 year later at time point two (t2). Results showed that the concurrent relationships between all three EF subcomponents and ToM pertained in middle childhood at t1 and t2, respectively, even when age, gender, and fluid intelligence were partialle dout. Moreover, cross-lagged structural equation modeling (again, controlling for age, gender, and fluid intelligence, as well as for the earlier levels of the target variables), revealed partial support for the view that early ToM predictslater EF, but stronger evidence for the assumption that early EF predictslater ToM. The latter was found for attention shifting and WM updating, but not for inhibition. This reveals the importance of studying the exact interplay of ToM and EF across childhood development, especially with regard to different EF subcomponents. Most likely, understanding others' mental states at different levels of perspective-taking requires specific EF subcomponents, suggesting developmental change in the relations between EF and ToM across childhood.

However, evidence of such preprocessing in fixations on the preceding word n when in fact the information about the preview is acquired is far less consistent. A recent study suggested that such effects may be delayed into fixations on the next word n + 1 (Risse & Kliegl, 2012). To investigate the time course of parafoveal information-acquisition on the control of eye movements during reading, we conducted 2 gaze-contingent display-change experiments and orthogonally manipulated the processing difficulty (i.e., word frequency) of an n + 1 preview word and its validity relative to the target word. Preview difficulty did not affect fixation durations on the pretarget word n but on the target word n + 1. In fact, the delayed preview-difficulty effect was almost of the same size as the preview benefit associated with the n + 1 preview validity. Based on additional results from quantile-regression analyses on the time course of the 2 preview effects, we discuss consequences as to the integration of foveal and parafoveal information and potential implications for computational models of eye guidance in reading.

However, recent research suggests differentiating "hot" affective and "cool" cognitive aspects of EF. Yet, findings regarding this two-factor construct are still inconsistent. In particular, the development of this factor structure remains unclear and data on school-aged children is lacking. Furthermore, studies linking EF and overweight or obesity suggest that EF contributes to the regulation of eating behavior. So far, however, the links between EF and eating behavior have rarely been investigated in children and non-clinical populations. First, we examined whether EF can be divided into hot and cool factors or whether they actually correspond to a unitary construct in middle childhood. Second, we examined how hot and cool EF are associated with different eating styles that put children at risk of becoming overweight during development. Hot and cool EF were assessed experimentally in a non-clinical population of 1657 elementary-school children (aged 6-11 years). The "food approach" behavior was rated mainly via parent questionnaires. Findings indicate that hot EF is distinguishable from cool EF. However, only cool EF seems to represent a coherent functional entity, whereas hot EF does not seem to be a homogenous construct. This was true for a younger and an older subgroup of children. Furthermore, different EF components were correlated with eating styles, such as responsiveness to food, desire to drink, and restrained eating in girls but not in boys. This shows that lower levels of EF are not only seen in clinical populations of obese patients but are already associated with food approach styles in a normal population of elementary school-aged girls. Although the direction of effect still has to be clarified, results point to the possibility that EF constitutes a risk factor for eating styles contributing to the development of overweight in the long-term.

Untreated, FAP is highly persistent until adulthood, also leading to an increased risk of psychiatric disorders. Intervention studies underscore the efficacy of cognitive behavioral treatment approaches but are limited in terms of sample size, long-term follow-up data, controls and inclusion of psychosocial outcome data. Methods/Design: In a multicenter randomized controlled trial, 112 children aged 7 to 12 years who fulfill the Rome III criteria for FAP will be allocated to an established cognitive behavioral training program for children with FAP (n = 56) or to an active control group (focusing on age-appropriate information delivery; n = 56). Randomization occurs centrally, blockwise and is stratified by center. This study is performed in five pediatric gastroenterology outpatient departments. Observer-blind assessments of outcome variables take place four times: pre-, post-, 3- and 12-months post-treatment. Primary outcome is the course of pain intensity and frequency. Secondary endpoints are health-related quality of life, pain-related coping and cognitions, as well as selfefficacy. Discussion: This confirmatory randomized controlled clinical trial evaluates the efficacy of a cognitive behavioral intervention for children with FAP. By applying an active control group, time and attention processes can be controlled, and long-term follow-up data over the course of one year can be explored.

Whereas incidental learning of motor sequences is well-established, few and disputed results support learning of perceptual sequences. Here we adapt a motion coherence discrimination task (Newsome & Pare, 1988) to the sequence learning paradigm. The new task has 2 advantages: (a) the stimulus is presented at fixation, thereby obviating overt eye movements, and (b) by varying coherence a perceptual threshold measure is available in addition to the performance measure of RT. Results from 3 experiments show that action relevance of the sequence is necessary for sequence learning to occur, that the amount of sequence knowledge varies with the ease of encoding the motor sequence, and that sequence knowledge, once acquired, has the ability to modify perceptual thresholds.

T1 - When less equals more: probability summation without sensitivity improvement T2 - Journal of experimental psychology : Human perception and performance N2 - Many perceptual and cognitive tasks permit or require the integrated cooperation of specialized sensory channels, detectors, or other functionally separate units. In compound detection or discrimination tasks, 1 prominent general mechanism to model the combination of the output of different processing channels is probability summation. The classical example is the binocular summation model of Pirenne (1943), according to which a weak visual stimulus is detected if at least 1 of the 2 eyes detects this stimulus; as we review briefly, exactly the same reasoning is applied in numerous other fields. It is generally accepted that this mechanism necessarily predicts performance based on 2 (or more) channels to be superior to single channel performance, because 2 separate channels provide "2 chances" to succeed with the task. We argue that this reasoning is misleading because it neglects the increased opportunity with 2 channels not just for hits but also for false alarms and that there may well be no redundancy gain at all when performance is measured in terms of receiver operating characteristic curves. We illustrate and support these arguments with a visual detection experiment involving different spatial uncertainty conditions. Our arguments and findings have important implications for all models that, in one way or another, rest on, or incorporate, the notion of probability summation for the analysis of detection tasks, 2-alternative forced-choice tasks, and psychometric functions.

Therefore, we examined in a sample of 1500 9th graders whether there are differential relationships between single subdimensions of intrinsic RM (object- vs. experience-related) and extrinsic RM (competition- vs. achievement-related) and comprehension of literary and expository texts. Results indicate that both dimensions of extrinsic RM are negatively (competition-related RM) or not significantly (achievement-related RM) associated with comprehension of literary and expository texts.

A series of studies support the notion that long-term appetite and weight regulation may be already programmed in early life and it could be demonstrated that the intrauterine environment affects the ghrelin system of the offspring. Animal studies have also shown that intrauterine programming of orexigenic systems persists even until adolescence/adulthood. Methods: We hypothesized that plasma ghrelin concentrations in adulthood may be associated with the intrauterine exposure to cigarette smoke. We examined this hypothesis in a sample of 19-year-olds followed up since birth in the framework of the Mannheim Study of Children at Risk, an ongoing epidemiological cohort study of the long-term outcome of early risk factors. Results: As a main finding, we found that ghrelin plasma concentrations in young adults who had been exposed to cigarette smoke in utero were significantly higher than in those without prenatal smoke exposure. Moreover, individuals with intrauterine nicotine exposure showed a significantly higher prevalence of own smoking habits and lower educational status compared to those in the group without exposure. Conclusion: Smoking during pregnancy may be considered as an adverse intrauterine influence that may alter the endocrine-metabolic status of the offspring even until early adulthood.

The association between numbers and space is well documented, but it is unknown whether arithmetic operation signs also have spatial associations and whether or not they contribute to spatial biases found in arithmetic. Adult participants classified plus and minus signs with left and right button presses under two counterbalanced response rules. Results from two experiments showed that spatially congruent responses (i.e., right-side responses for the plus sign and left-side responses for the minus sign) were responded to faster than spatially incongruent ones (i.e., left-side responses for the plus sign and right-side responses for the minus sign). We also report correlations between this novel operation sign spatial association (OSSA) effect and other spatial biases in number processing. In a control experiment with no explicit processing requirements for the operation signs there were no sign-related spatial biases. Overall, the results suggest that (a) arithmetic operation signs can evoke spatial associations (OSSA), (b) experience with arithmetic operations probably underlies the OSSA, and (c) the OSSA only partially contributes to spatial biases in arithmetic.

Evidence for this claim is, however, controversial. The present study now aims to compare vertical and horizontal spatial associations in mental arithmetic. In Experiment 1, participants solved addition and subtraction problems and indicated the result verbally while moving their outstretched right arm continuously left-, right-, up-, or downwards. The analysis of the problem-solving performances revealed a motion-arithmetic compatibility effect for spatial actions along both the horizontal and the vertical axes. Performances in additions was impaired while making downward compared to upward movements as well as when moving left compared to right and vice versa in subtractions. In Experiment 2, instead of being instructed to perform active body movements, participants calculated while the problems moved in one of the four relative directions on the screen. For visual motions, only the motion-arithmetic compatibility effect for the vertical dimension could be replicated. Taken together, our findings provide first evidence for an impact of spatial processing on mental arithmetic. Moreover, the stronger effect of the vertical dimension supports the idea that mental calculations operate on representations of numerical magnitude that are grounded in a vertically organized mental number space.

Results clearly indicate that, only identical and orthographically similar previews facilitated processing of the target words when they were subsequently fixated. More critically, more parafoveal information was obtained by subjects with higher reading proficiency. These results suggest that, mainly low-level features of the parafoveal words are obtained by the non-native Chinese readers and less attentional resources are available for the readers with lower reading proficiency, thereby causing a reduction of the perceptual span.

When workplace-related anxieties manifest, absenteeism, long-term-sick leave, and even disability pension can be the consequences. In medical-vocational rehabilitation about 30-60 % of the patients suffer from workplace-related anxieties that are often a barrier for return to work. Even in mentally healthy employees, 5 % said that they were prone to ask for a sick leave certificate due to workplace-related anxieties. Future research should focus on workplace-related anxieties not only in rehabilitation, but more earlier, i. e. in the workplace. The concept of workplace-related anxieties offers ideas which can be useful in mental-health-oriented work analysis, employee-workplace-fit, and job design.

The Performance Enhancement Attitude Scale (PEAS) was employed as a corresponding direct measure in order to additionally validate the results. Results: As expected, in the group of bodybuilders, indirectly measured doping attitudes as tested with the picture-based doping-BIAT were significantly less negative (eta(2) = .11). The doping-BIAT and PEAS scores correlated significantly at r = .50 for bodybuilders, and not significantly at r = .36 for handball players. There was a low error rate (7%) and a satisfactory internal consistency (r(dagger dagger) = .66) for the picture-based doping-BIAT. Conclusions: The picture-based doping-BIAT constitutes a psychometrically tested method, ready to be adopted by the international research community. The test can be administered via the internet. All test material is available "open source". The test might be implemented, for example, as a new effect-measure in the evaluation of prevention programs.

School staff who are confronted with leaking have to assess its seriousness and react appropriately - a difficult task, because knowledge about leaking is sparse. The present study, therefore, examined how frequently leaking occurs in schools and how teachers identify leaking and respond to it. To achieve this aim, we informed teachers from eight schools in Germany about the definition of leaking and other warning signs and risk factors for school shootings in a one-hour information session. Teachers were then asked to report cases of leaking over a six- to nine-month period and to answer a questionnaire on leaking and its treatment after the information session and six to nine months later. Our results suggest that leaking is a relevant problem in German schools. Teachers mostly rated the information session positively and benefited in several aspects (e.g. reported more perceived courses of action or improved knowledge about leaking), but also expressed a constant need for support. Our findings highlight teachers' needs for further support and training and may be used in the planning of prevention measures for school shootings.

Movement trajectories of the cursor can then be reconstructed off-line to assess the efficiency of responding in time and across space. Here we focus on the process of selecting among alternative numerical responses. Several studies have recently measured the mathematical mind with cursor movements while people decided about number magnitude or parity, computed sums or differences, or simply located numbers on a number line. After some general methodological considerations about mouse tracking we discuss several conceptual concerns that become particularly evident when "mousing" the mathematical mind.

Given that a later event (i.e., conscious awareness) cannot cause an earlier one (i.e., decision-related brain activity), such results have been interpreted as evidence that decisions are made unconsciously (e.g., Libet, 1985). We argue that this interpretation depends upon an all-or-none view of consciousness, and we offer an alternative interpretation of the early decision-related brain activity based on models in which conscious awareness of the decision to move develops gradually up to the level of a reporting criterion. Under this interpretation, the early brain activity reflects sub-criterion levels of awareness rather than complete absence of awareness and thus does not suggest that decisions are made unconsciously.

Research investigating the neurobiological underpinnings of this disorder has implicated deficits during response inhibition. Attempts to uncover the effect of prenatal exposure to nicotine on inhibitory control may thus be of high clinical importance. MAIN OUTCOMES AND MEASURES: Functional magnetic resonance imaging response, morphometric data, lifetime ADHD symptoms, and novelty seeking. RESULTS: Participants prenatally exposed to nicotine exhibited a weaker response in the anterior cingulate cortex (t(168) = 4.46; peak Montreal Neurological Institute [MNI] coordinates x = -2, y = 20, z = 30; familywise error [FWE]-corrected P = .003), the right inferior frontal gyrus (t(168) = 3.65; peak MNI coordinates x = 44, y = 38, z = 12; FWE-corrected P = .04), the left inferior frontal gyrus (t(168) = 4.09; peak MNI coordinates x = -38, y = 36, z = 8; FWE-corrected P = .009), and the supramarginal gyrus (t(168) = 5.03; peak MNI coordinates x = 64, y = -28, z = 22; FWE-corrected P = .02) during the processing of the NoGo compared to neutral stimuli, while presenting a decreased volume in the right inferior frontal gyrus. These findings were obtained irrespective of the adjustment of confounders, ADHD symptoms, and novelty seeking. There was an inverse relationship between inferior frontal gyrus activity and ADHD symptoms and between anterior cingulate cortex activity and novelty seeking. CONCLUSIONS AND RELEVANCE: These findings point to a functional involvement of prenatal exposure to tobacco smoke in neural alterations similar to ADHD, which underlines the importance of smoking prevention treatments.

Most important is workplace phobia, that is, panic when approaching or even thinking of the workplace. This study is the first to estimate the prevalence of workplace phobia among primary care patients suffering from chronic mental disorders and to describe which illness-related or workplace-specific context factors are associated with workplace phobia. Methods: A convenience sample of 288 primary care patients with chronic mental disorders (70% women) seen by 40 primary care clinicians in Germany were assessed using a standardized diagnostic interview about mental disorders and workplace problems. Workplace phobia was assessed by the Workplace Phobia Scale and a structured Diagnostic and Statical Manual of Mental Disorders-based diagnostic interview. In addition, capacity and participation restrictions, illness severity, and sick leave were assessed. Results: Workplace phobia was found in 10% of patients with chronic mental disorders, that is, approximately about 3% of all general practice patients. Patients with workplace phobia had longer durations of sick leave than patients without workplace phobia and were impaired to a higher degree in work-relevant capacities. They also had a higher degree of restrictions in participation in other areas of life. Conclusions: Workplace phobia seems to be a frequent problem in primary care. It may behoove primary care clinicians to consider workplace-related anxiety, including phobia, particularly when patients ask for a work excuse for nonspecific somatic complaints.

Tropic representational features reflect constraints of the physical world on the agent's ability to form, reactivate, and enrich embodied (i.e., resulting from the agent's bodily constraints) conceptual representations embedded in situated contexts. The proposed hierarchy entails that representations can, in principle, have tropic features without necessarily having situated and/or embodied features. On the other hand, representations that are situated and/or embodied are likely to be simultaneously tropic. Hence, although we propose tropism as the most general term, the hierarchical relationship between embodiment and situatedness is more on a par, such that the dominance of one component over the other relies on the distinction between offline storage versus online generation as well as on representation-specific properties.

T1 - Occipital and orbitofrontal hemodynamics during naturally paced reading: An fNIRS study JF - NeuroImage : a journal of brain function N2 - Humans typically read at incredibly fast rates, because they predict likely occurring words from a given context. Here, we used functional near-infrared spectroscopy (fNIRS) to track the ultra-rapid hemodynamic responses of words presented every 280 ms in a naturally paced sentence context. We found a lower occipital deoxygenation to unpredictable than to predictable words. The greater hemodynamic responses to unexpected words suggest that the visual features of expected words have been pre-activated previous to stimulus presentation. Second, we tested opposing theoretical proposals about the role of the medial orbitofrontal cortex (OFC): Either OFC may respond to the breach of expectation; or OFC is activated when the present stimulus matches the prediction. A significant interaction between word frequency and predictability indicated OFC responses to breaches of expectation for low- but not for high-frequency words: OFC is sensitive to both, bottom-up processing as mediated by word frequency, as well as top-down predictions. Particularly, when a rare word is unpredictable, OFC becomes active. Finally, we discuss how a high temporal resolution can help future studies to disentangle the hemodynamic responses of single trials in such an ultra-rapid event succession as naturally paced reading.

In two experiments using Uighur script known for its rich suffixes, we demonstrate that, in addition to word length and launch site, the number of suffixes influences initial landing positions. We also demonstrate an influence of word frequency. These results are difficult to explain purely by low-level guidance of eye movements and indicate that due to properties specific to Uighur script low-level visual information and high-level information such as morphological structure of parafoveal words jointly influence saccade programming.

N2 - This study investigates the eye movements of dyslexic children and their age-matched controls when reading Chinese. Dyslexic children exhibited more and longer fixations than age-matched control children, and an increase of word length resulted in a greater increase in the number of fixations and gaze durations for the dyslexic than for the control readers. The report focuses on the finding that there was a significant difference between the two groups in the fixation landing position as a function of word length in single-fixation cases, while there was no such difference in the initial fixation of multi-fixation cases. We also found that both groups had longer incoming saccade amplitudes while the launch sites were closer to the word in single fixation cases than in multi-fixation cases. Our results suggest that dyslexic children's inefficient lexical processing, in combination with the absence of orthographic word boundaries in Chinese, leads them to select saccade targets at the beginning of words conservatively. These findings provide further evidence for parafoveal word segmentation during reading of Chinese sentences.

The present study aimed to replicate and extend previous evidence indicating that FKBP5 polymorphisms moderate hypothalamus-pituitary-adrenal (HPA) function by examining whether FKBP5 rs1360780 genotype and different measures of childhood adversity interact to predict stress-induced cortisol secretion. At age 19 years, 195 young adults (90 males, 105 females) participating in an epidemiological cohort study completed the Trier Social Stress Test (TSST) to assess cortisol stress responsiveness and were genotyped for the FKBP5 rs1360780. Childhood adversity was assessed using the Childhood Trauma Questionnaire (CTQ) and by a standardized parent interview yielding an index of family adversity. A significant interaction between genotype and childhood adversity on cortisol response to stress was demonstrated for exposure to childhood maltreatment as assessed by retrospective self-report (CTQ), but not for prospectively ascertained objective family adversity. Severity of childhood maltreatment was significantly associated with attenuated cortisol levels among carriers of the rs1360780 CC genotype, while no such effect emerged in carriers of the T allele. These findings point towards the functional involvement of FKBP5 in long-term alterations of neuroendocrine stress regulation related to childhood maltreatment, which have been suggested to represent a premorbid risk or resilience factor in the context of stress-related disorders.

An alternative hypothesis considers numbers as elements of a generalized representation of sensorimotor-related magnitude, which is not obligatorily spatial. Here we show that individuals' relative use of spatial and nonspatial representations has a cerebral counterpart in the structural organization of the posterior parietal cortex. Interindividual variability in the linkage between numbers and spatial responses (faster left responses to small numbers and right responses to large numbers; spatial-numerical association of response codes effect) correlated with variations in gray matter volume around the right precuneus. Conversely, differences in the disposition to link numbers to force production (faster soft responses to small numbers and hard responses to large numbers) were related to gray matter volume in the left angular gyrus. This finding suggests that numerical cognition relies on multiple mental representations of analogue magnitude using different neural implementations that are linked to individual traits.

However, not all syntactic processes are equally problematic: present time reference, who questions, and reflexives can be processed by narrow syntax alone and are relatively spared compared to past time reference, which questions, and personal pronouns, respectively. The latter need additional access to discourse and information structures to link to their referent outside the clause (Avrutin, 2006). Linguistic processing that requires discourse-linking is difficult for agrammatic individuals: verb morphology with reference to the past is more difficult than with reference to the present (Bastiaanse et al., 2011). The same holds for which questions compared to who questions and for pronouns compared to reflexives (Avrutin, 2006). These results have been reported independently for different populations in different languages. The current study, for the first time, tested all conditions within the same population. Aims: We had two aims with the current study. First, we wanted to investigate whether discourse-linking is the common denominator of the deficits in time reference, wh questions, and object pronouns. Second, we aimed to compare the comprehension of discourse-linked elements in people with agrammatic and fluent aphasia. Methods and procedures: Three sentence-picture-matching tasks were administered to 10 agrammatic, 10 fluent aphasic, and 10 non-brain-damaged Russian speakers (NBDs): (1) the Test for Assessing Reference of Time (TART) for present imperfective (reference to present) and past perfective (reference to past), (2) the Wh Extraction Assessment Tool (WHEAT) for which and who subject questions, and (3) the Reflexive-Pronoun Test (RePro) for reflexive and pronominal reference. Outcomes and results: NBDs scored at ceiling and significantly higher than the aphasic participants. We found an overall effect of discourse-linking in the TART and WHEAT for the agrammatic speakers, and in all three tests for the fluent speakers. Scores on the RePro were at ceiling. Conclusions: The results are in line with the prediction that problems that individuals with agrammatic and fluent aphasia experience when comprehending sentences that contain verbs with past time reference, which question words and pronouns are caused by the fact that these elements involve discourse linking. The effect is not specific to agrammatism, although it may result from different underlying disorders in agrammatic and fluent aphasia.

Increased dietary fat intake increases blood endocannabinoids and alters adipose and skeletal muscle ECS gene expression in human. Methods: Two weeks isocaloric low- (LFD) and high-fat diets (HFD) in obese (n = 12) and normal- weight (n = 17) subjects in a randomized cross-over study were compared. Blood endocannabinoids were measured in the fasting condition and after food intake using mass spectrometry. Adipose and skeletal muscle gene expression was determined using real-time RT-PCR. Results: Baseline fasting plasma endocannabinoids were similar with both diets. Anandamide decreased similarly with high- or low-fat test meals in both groups. Baseline arachidonoylglycerol plasma concentrations were similar between groups and diets, and unresponsive to eating. In subcutaneous adipose tissue, DAGL-alpha mRNA was upregulated and fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL) mRNAs were down-regulated in obese subjects, but the diets had no influence. In contrast, the HFD produced pronounced reductions in skeletal muscle CB1-R and MAGL mRNA expression, whereas obesity did not affect muscular gene expression. Conclusions: Weight-neutral changes in dietary fat intake cannot explain excessive endocannabinoid availability in human obesity. Obesity and dietary fat intake affect ECS gene expression in a tissue-specific manner.

T1 - Syllable articulation influences foveal and parafoveal processing of words during the silent reading of Chinese sentences JF - Journal of memory and language N2 - The current study examined effects of syllable articulation on eye movements during the silent reading of Chinese sentences, which contained two types of two-character target words whose second characters were subject to dialect-specific variation. In one condition the second syllable was articulated with a neutral tone for northern-dialect Chinese speakers and with a full tone for southern-dialect Chinese speakers (neutral-tone target words) and in the other condition the second syllable was articulated with a full tone irrespective of readers' dialect type (full-tone target words). Native speakers of northern and southern Chinese dialects were recruited in Experiment 1 to examine the effect of dialect-specific articulation on silent reading. Recordings of their eye movements revealed shorter viewing durations for neutral- than for full-tone target words only for speakers of northern but not for southern dialects, indicating that dialect-specific articulation of syllabic tone influenced visual word recognition. Experiment 2 replicated the syllabic tone effect for speakers of northern dialects, and the use of gaze-contingent display changes further revealed that these readers processed an upcoming parafoveal word less effectively when a neutral- than when a full-tone target was fixated. Shorter viewing duration for neutral-tone words thus cannot be attributed to their easier lexical processing; instead, tonal effects appear to reflect Chinese readers' simulated articulation of to-be-recognized words during silent reading.

A genetic variant that has repeatedly been reported to render individuals more sensitive to the presence of adverse experiences, including stress exposure during fetal life, is the seven-repeat allele of the dopamine D4 receptor (DRD4) gene. The present investigation concentrated on the interplay of prenatal maternal stress and DRD4 genotype in predicting self-reported aggression in young adults. As disruption of the hypothalamic-pituitary-adrenal system has been discussed as a pathophysiological pathway to aggression, cortisol stress reactivity was additionally examined. As part of an epidemiological cohort study, prenatal maternal stress was assessed by maternal interview 3 months after childbirth. Between the ages of 19 and 23 years, 298 offspring (140 males, 158 females) completed the Young Adult Self-Report to measure aggressive behavior and were genotyped for the DRD4 gene. At 19 years, 219 participants additionally underwent the Trier Social Stress Test to determine cortisol reactivity. Extending earlier findings with respect to childhood antisocial behavior, the results revealed that, under conditions of higher prenatal maternal stress, carriers of the DRD4 seven-repeat allele displayed more aggression in adulthood (p = 0.032). Moreover, the same conditions which seemed to promote aggression were found to predict attenuated cortisol secretion (p = 0.028). This is the first study to indicate a long-term impact of prenatal stress exposure on the cortisol stress response depending on DRD4 genotype.

Mothers who did not breastfeed were less likely to be informed by their paediatrician or midwife and were more often not informed at all; 27.8 % of mothers used DHA supplements during pregnancy, 16.8 % postnatal. DHA supplementation was more common in women with a high versus a low fish intake. The social status was the major determinant of breastfeeding initiation and exclusivity and also DHA supplementation. Breastfeeding initiation and duration of exclusive breastfeeding in Germany need to be improved. Professional counselling and support, with a focus on mothers from lower social classes, appears necessary to increase current rates of breastfeeding initiation, duration, and exclusiveness, but also to ensure a sufficient supply with DHA in pregnant and lactating women, particularly in women with low fish consumption.

However, in previous studies intentionality has often been confounded with agency defined as perceiving the initiator of an action as being the causal source of the action. The aim of the present study was to disentangle the role of agency and intentionality as modulating factors of the JSE. In Experiment 1, participants performed a joint go/nogo Simon task next to a co-actor who either intentionally controlled a response button with own finger movements (agency+/intentionality+) or who passively placed the hand on a response button that moved up and down on its own as triggered by computer signals (agency-/intentionality-). In Experiment 2, we included a condition in which participants believed that the co-actor intentionally controlled the response button with a Brain-Computer Interface (BCI) while placing the response finger clearly besides the response button, so that the causal relationship between agent and action effect was perceptually disrupted (agency-/intentionality+). As a control condition, the response button was computer controlled while the co-actor placed the response finger besides the response button (agency-/intentionality-). Experiment 1 showed that the JSE is present with an intentional co-actor and causality between co-actor and action effect, but absent with an unintentional co-actor and a lack of causality between co-actor and action effect. Experiment 2 showed that the JSE is absent with an intentional co-actor, but no causality between co-actor and action effect. Our findings indicate an important role of the co-actor's agency for the JSE. They also suggest that the attribution of agency has a strong perceptual basis.

According to current theories, a series of successive stages consisting of the registration, identification, and categorization of the sound has to be completed before participants are able to report the sound as a target by button press after similar to 300-500 ms. Here we use miniature eye movements as a tool to study the categorization of a sound as a target or nontarget, indicating that an initial categorization is present already after 80-100 ms. During visual fixation, the rate of microsaccades, the fastest components of miniature eye movements, is transiently modulated after auditory stimulation. In two experiments, we measured microsaccade rates in human participants in an auditory three-tone oddball paradigm (including rare nontarget sounds) and observed a difference in the microsaccade rates between targets and nontargets as early as 142 ms after sound onset. This finding was replicated in a third experiment with directed saccades measured in a paradigm in which tones had to be matched to score-like visual symbols. Considering the delays introduced by (motor) signal transmission and data analysis constraints, the brain must have differentiated target from nontarget sounds as fast as 80-100 ms after sound onset in both paradigms. We suggest that predictive information processing for expected input makes higher cognitive attributes, such as a sound's identity and category, available already during early sensory processing. The measurement of eye movements is thus a promising approach to investigate hearing.

The present study examined the impact of early life adversity on different stages of neuronal reward processing later in life and their association with a related behavioral phenotype, i.e. attention deficit/hyperactivity disorder (ADHD). 162 healthy young adults (mean age = 24.4 years; 58% female) from an epidemiological cohort study followed since birth participated in a simultaneous EEG-fMRI study using a monetary incentive delay task. Early life adversity according to an early family adversity index (EFA) and lifetime ADHD symptoms were assessed using standardized parent interviews conducted at the offspring's age of 3 months and between 2 and 15 years, respectively. fMRI region-of-interest analysis revealed a significant effect of EFA during reward anticipation in reward-related areas (i.e. ventral striatum, putamen, thalamus), indicating decreased activation when EFA increased. EEG analysis demonstrated a similar effect for the contingent negative variation (CNV), with the CNV decreasing with the level of EFA. In contrast, during reward delivery, activation of the bilateral insula, right pallidum and bilateral putamen increased with EFA. There was a significant association of lifetime ADHD symptoms with lower activation in the left ventral striatum during reward anticipation and higher activation in the right insula during reward delivery. The present findings indicate a differential long-term impact of early life adversity on reward processing, implicating hyporesponsiveness during reward anticipation and hyperresponsiveness when receiving a reward. Moreover, a similar activation pattern related to lifetime ADHD suggests that the impact of early life stress on ADHD may possibly be mediated by a dysfunctional reward pathway.

Grounded in recent research on personality development from a broad interactionist theoretical approach, the present article investigates whether work characteristics, including job demands, job control, social support from supervisors and coworkers, and organizational constraints, change proactive personality over time and, more important, reciprocal relationships between proactive personality and work characteristics. Latent change score analyses based on longitudinal data collected in 3 waves across 3 years show that job demands and job control have positive lagged effects on increases in proactive personality. In addition, proactive personality exerts beneficial lagged effects on increases in job demands, job control, and supervisory support, and on decreases in organizational constraints. Dynamic reciprocal relationships are observed between proactive personality with job demands and job control. The revealed corresponsive change relationships between proactive personality and work characteristics contribute to the proactive personality literature by illuminating more nuanced interplays between the agentic person and work characteristics, and also have important practical implications for organizations and employees.

Infants' goal-directed gaze shifts were recorded as they observed action sequences in a multiple-goals design. We found that 12-month-old infants exhibited gaze shifts significantly earlier when the observed hand reached for the same goal object in all trials (frequent condition) compared with when the observed hand reached for different goal objects across trials (nonfrequent condition). Infants in the frequent condition were significantly more accurate at predicting the action goal than infants in the nonfrequent condition. In addition, findings revealed rapid learning in the case of certainty and no learning in the case of uncertainty of goal selection over the course of trials. Together, our data indicate that by the end of their first year of life, infants rely on information about the certainty of goal selection to make inferences about others' action goals.

In Experiment 1, participants successfully solved three cognitive tasks and attributed the success either internally (i.e., to themselves) or externally (i.e., to a teammate). We found no effect of optimism, but a significant effect of the attribution: Internal attribution predicted an increase in feelings of success. In Experiment 2, we replicated the design and adopted an extreme groups approach in order to include the extremes of the optimism dimension. Only optimism affected feelings of success in this sample: Pessimistic participants showed higher increases in feelings of success than optimistic participants. We conclude that optimism, if disentangled from attribution, may have an effect on affect, with pessimism showing potential affective benefits. However, this association may be concealed if samples with a restricted range of the optimism dimension are studied.

Nach der kognitiven Theorie der Depression von Beck (1967, 1996) führen dysfunktionale Einstellungen in Interaktion mit Stress zu depressiven Symptomen. Es existieren allerdings nur wenige Studien, die die longitudinale Beziehung zwischen den dysfunktionalen Einstellungen und der Depressivität bei Kindern und Jugendlichen untersucht haben (Lakdawalla et al., 2007). Folglich kann noch nicht eindeutig geklärt werden, ob die dysfunktionalen Einstellungen Ursache, Begleiterscheinung oder Konsequenz der Depression sind. Als Datengrundlage diente eine Stichprobe von Kindern und Jugendlichen im Alter von 9 bis 20 Jahren, die im Rahmen der PIER-Studie zu dysfunktionalen Einstellungen, kritischen Lebensereignissen und depressiven Symptomen befragt wurden (Nt1t2 = 1.053; t1: 2011/2012, t2: 2013/2014). Querschnittliche Analysen zeigten hohe Assoziationen zwischen den dysfunktionalen Einstellungen, kritischen Lebensereignissen und depressiven Symptomen. Eine latente Moderationsanalyse wies nur bei den Jugendlichen auf signifikante Interaktion zwischen den dysfunktionalen Einstellungen und den kritischen Lebensereignissen in der Vorhersage depressiver Symptomatik hin. Im Längsschnitt zeigten latente Cross-Lagged-Panel-Analysen erwartungsgemäß, dass die dysfunktionalen Einstellungen und die Depressivität mit dem Alter immer stabilere Konstrukte darstellen, die sehr eng miteinander zusammenhängen. Eine diesem Modell hinzugefügte latente Moderationsanalyse konnte das kognitive Modell der Depression nach Beck weder bei Kindern noch bei Jugendlichen bestätigen. Die spätere depressive Symptomatik konnte lediglich durch Haupteffekte der früheren Ausprägung der Depressivität und der kritischen Lebensereignisse vorhergesagt werden. Diese Ergebnisse legen den Schluss nahe, dass es sich bei den dysfunktionalen Einstellungen eher um Begleiterscheinungen als um Risikofaktoren oder Konsequenzen der depressiven Symptomatik handelt. N2 - This study examined the meaning of dysfunctional attitudes for the development of depressive symptoms in childhood and adolescence. According to Beck’s cognitive theory of depression (1967, 1996) dysfunctional attitudes activated by stressors play a causal role in the development of depression. However, there are only a few studies which investigate the longitudinal relationship between dysfunctional attitudes and depression in children and adolescents (Lakdawalla et al., 2007). Hence, there is a lack of evidence regarding the question, whether dysfunctional attitudes are regarded as causes, concomitants or consequences of depression. In the context of the Pier Study, dysfunctional attitudes, stressful life events and depressive symptoms were assessed in children and adolescents aged 9 to 20 at two measurement points (t1: 2011/2012, t2: 2013/2014; Nt1-t2 = 1.053). Cross-sectional results revealed strong associations between dysfunctional attitudes, stressful life events and depressives symptoms. A latent moderator analysis was conducted and showed a significant interaction between dysfunctional attitudes and stressful life events in predicting depressive symptoms only for adolescents, but not for children. Longitudinally, a latent cross-lagged-panel analysis revealed that dysfunctional attitudes and depressive symptoms are stable and highly correlated constructs. A moderator analysis within this cross-lagged-panel-model couldn’t corroborate Beck’s cognitive model of depression neither in children nor in adolescents. Thus, only prior depressive symptoms and stressful life events could predict depressive symptoms. In conclusion dysfunctional attitudes are concomitants rather than causes or consequences of depression.

Aus- und Weiterbildungsangebote zur Vermittlung lehrerspezifischer sozialer Kompetenzen spielen eine wichtige Rolle bei der Förderung der Lehrergesundheit. In der vorliegenden Studie wurde das „Lehrer/innen-Coaching nach dem Freiburger Modell“ evaluiert, welches die Kompetenz von Lehrkräften stärken soll, innerhalb der Schule und insbesondere im Unterricht, schwierige interpersonelle Situationen aktiv und konstruktiv zu gestalten. Damit sollen stressbedingte gesundheitliche Belastungen abgebaut und dem Entstehen gravierender psychischer Störungen vorgebeugt werden. In der vorliegenden Arbeit werden zwei modifizierte Versionen dieses Programms erstmalig im Rahmen einer landesweiten Feldstudie untersucht. Die zentralen Evaluationsfragestellungen beziehen sich auf die Effektivität der Intervention als Gesundheitsförderungsmaßnahme (Akzeptanz, Wirksamkeit, Wirksamkeitsvergleich der beiden Interventionsformen im landesweiten Einsatz). Daneben strebt die Studie einen Vergleich mit den Ergebnissen einer Vorgängerstudie sowie die Generierung weiterer Erkenntnisse zum Zusammenhang zwischen Aspekten der sozialen Kompetenz von Lehrkräften und ihrer psychischen Gesundheit an. An der Maßnahme konnten alle baden-württembergischen Lehrerinnen und Lehrer mit einer Berufserfahrung von mindestens 10 Jahren teilnehmen. Für die Untersuchung der Wirksamkeit der Maßnahme und des Wirksamkeitsvergleichs der beiden unterschiedlichen Formen liegt ein quasiexperimentelles Design mit insgesamt zwei Messzeitpunkten vor. In die Auswertung zur Wirksamkeit der Intervention konnten die Daten von den 314 Teilnehmern einbezogen werden. Die Messinstrumente, die in der vorliegenden Studie zur Anwendung kamen, waren der General Health Questionnaire (GHQ-12), das Maslach Burnout Inventory (MBI-D) und die ins Deutsche übersetzte Jefferson Scale of Empathy (JSE) in der an Lehrer adaptierten Form. Die Evaluationsergebnisse zeigen, dass die Teilnahme am „Lehrer/innen-Coaching nach dem Freiburger Modell” mit einer signifikanten Verbesserung der gesundheitsbezogenen abhängigen Variablen einhergeht. Besonders hervorzuheben ist die ausgeprägte Verbesserung der mittels GHQ-12 erfassten psychischen Gesundheit. Das Ergebnis des Prä-Post-Vergleichs der Gesundheitswerte beider Interventionsgruppen bestätigte sich auch im Vergleich zu einer Null-Interventionsgruppe: Entsprechend der Hypothese gab es bei den Teilnehmern eine signifikant stärkere Verbesserung der psychischen Gesundheit als bei den Nicht-Teilnehmern (Null-Interventionsgruppe). Die beiden Interventionsmodi „Kompaktform” und „Kurzform” erwiesen sich im Hinblick auf die Verbesserung der Lehrergesundheit als gleichermaßen wirksam. Zudem zeigen die Ergebnisse der Teilnehmerbefragung, dass die Maßnahme Anklang bei der Zielgruppe fand. Die Akzeptanz durch die Zielgruppe ist für die Wirksamkeit einer auf Freiwilligkeit basierenden verhaltenspräventiven Maßnahme naturgemäß eine essenzielle Voraussetzung. Bei der psychischen Gesundheit der Lehrer bestehen – wie aus weiteren Befunden der Studie ersichtlich – bedeutsame Zusammenhänge zu einer intakten zwischenmenschlichen Beziehung mit den Schülern, einer gelungenen, durch gegenseitige Unterstützung gekennzeichneten Interaktion im Kollegium und einem entsprechend unterstützenden Führungsverhalten der Schulleitung. Dies macht deutlich, welches besondere Gewicht einer gelingenden Beziehungsgestaltung an Schulen und im Unterricht beizumessen ist. Bezüglich der Vorgehensweise in der vorliegenden Untersuchung werden einige methodische Limitationen hinsichtlich des Designs diskutiert. Ergänzend wird im Ausblick der Evaluationsstudie darauf hingewiesen, wie sich durch die Verknüpfung des vorliegenden Programms mit weiteren, auf den Ebenen Verhalten, Verhältnisse und Führung ansetzenden gesundheitspräventiven Maßnahmen, zukünftig die Stärkung der psychischen Gesundheit von Lehrkräften weiter ausbauen ließe. N2 - Teachers are affected by stress-related health disorders at especially high rates. One of the main factors influencing teachers’ health are interpersonal conflicts which teachers are continuously confronted with. Improving specific social competencies helps teachers to cope with difficult interpersonal situations in school and thus to reduce stress-related health problems. The aim of this study was to evaluate the effects and the acceptance of two modified versions of a manual-based group coaching program entitled „Lehrer/innen-Coaching nach dem Freiburger Modell“. In its original version it was found to be effective in enhancing teachers’ health by improving their interpersonal competencies. Furthermore, this study extends previous investigations of the group coaching to a more widespread setting including all school types and all school districts in the German federal state of Baden-Württemberg. All teachers of all school types in Baden-Württemberg with a job experience of 10 years and more were invited to take part in the program. The study design was quasi-experimental with a pre-post-design and two treatment conditions to compare. The effectiveness of the intervention was measured with the General Health Questionnaire (GHQ-12), the Maslach Burnout Inventory (MBI-D) and the Jefferson Scale of Empathy (JSE). The latter was especially adapted to teachers and examined for its psychometric qualities. The results show that all health parameters of the N = 314 participating teachers significantly improved after the treatment. A remarkable result is the pronounced improvement of the GHQ-score with a strong effect size. The positive effects of the program on teachers’ health could also be confirmed in comparison to a non-treatment group, which was included post-hoc. No differences were found in the effectiveness of the two modified versions of the treatment. The participants’ acceptance of the group program was high. In accordance to previous studies further findings revealed significant positive correlations of intact interpersonal relationships, support by colleagues and school heads and a good state of mental health. As the results reveal, the two modified versions of the group coaching program „Lehrer/innen-Coaching nach dem Freiburger Modell“ are effective for enhancing teachers’ mental health. Some methodical limitations of the study design are discussed. Complementary, it is pointed out how teachers’ health may further be improved by combining this group coaching with additional interventions on the level of behavior, working conditions and leadership.

Recent work suggests that a genetic variation associated with increased dopamine metabolism in the prefrontal cortex (catechol-O-methyltransferase Val158Met; COMT) amplifies age-related changes in working memory performance. Research on younger adults indicates that the influence of dopamine-related genetic polymorphisms on working memory performance increases when testing the cognitive limits through training. To date, this has not been studied in older adults. Method. Here we investigate the effect of COMT genotype on plasticity in working memory in a sample of 14 younger (aged 24-30 years) and 25 older (aged 60-75 years) healthy adults. Participants underwent adaptive training in the n-back working memory task over 12 sessions under increasing difficulty conditions. Results. Both younger and older adults exhibited sizeable behavioral plasticity through training (P < .001), which was larger in younger as compared to older adults (P < .001). Age-related differences were qualified by an interaction with COMT genotype (P < .001), and this interaction was due to decreased behavioral plasticity in older adults carrying the Val/Val genotype, while there was no effect of genotype in younger adults. Discussion. Our findings indicate that age-related changes in plasticity in working memory are critically affected by genetic variation in prefrontal dopamine metabolism.

CY - New York ER - TY - THES A1 - Krügel, André T1 - Eye movement control during reading : factors and principles of computing the word center for saccade planning T1 - Augenbewegungskontrolle beim Lesen : Faktoren und Prinzipien der Bestimmung der Wortmitte zur Sakkadenplanung N2 - Reading is a complex cognitive task based on the analyses of visual stimuli. Due to the physiology of the eye, only a small number of letters around the fixation position can be extracted with high visual acuity, while the visibility of words and letters outside this so-called foveal region quickly drops with increasing eccentricity. As a consequence, saccadic eye movements are needed to repeatedly shift the fovea to new words for visual word identification during reading. Moreover, even within a foveated word fixation positions near the word center are superior to other fixation positions for efficient word recognition (O’Regan, 1981; Brysbaert, Vitu, and Schroyens, 1996). Thus, most reading theories assume that readers aim specifically at word centers during reading (for a review see Reichle, Rayner, & Pollatsek, 2003). However, saccades’ landing positions within words during reading are in fact systematically modulated by the distance of the launch site from the word center (McConkie, Kerr, Reddix, & Zola, 1988). In general, it is largely unknown how readers identify the center of upcoming target words and there is no computational model of the sensorimotor translation of the decision for a target word into spatial word center coordinates. Here we present a series of three studies which aim at advancing the current knowledge about the computation of saccade target coordinates during saccade planning in reading. Based on a large corpus analyses, we firstly identified word skipping as a further factor beyond the launch-site distance with a likewise systematic and surprisingly large effect on within-word landing positions. Most importantly, we found that the end points of saccades after skipped word are shifted two and more letters to the left as compared to one-step saccades (i.e., from word N to word N+1) with equal launch-site distances. Then we present evidence from a single saccade experiment suggesting that the word-skipping effect results from highly automatic low-level perceptual processes, which are essentially based on the localization of blank spaces between words. Finally, in the third part, we present a Bayesian model of the computation of the word center from primary sensory measurements of inter-word spaces. We demonstrate that the model simultaneously accounts for launch-site and saccade-type contingent modulations of within-word landing positions in reading. Our results show that the spatial saccade target during reading is the result of complex estimations of the word center based on incomplete sensory information, which also leads to specific systematic deviations of saccades’ landing positions from the word center. Our results have important implications for current reading models and experimental reading research. N2 - Lesen ist eine komplexe kognitive Aufgabe, die auf der Analyse visueller Reize beruht. Aufgrund der Physiologie des Auges kann jedoch nur eine kleine Anzahl von Buchstaben um den Fixationsort mit hoher visueller Genauigkeit wahrgenommen werden, während die Sichtbarkeit der Buchstaben und Wörter außerhalb der sogenannten fovealen Zone mit zunehmender Entfernung stark abnimmt. Während des Lesens sind deshalb sakkadische Augenbewegungen erforderlich, um die Fovea zur visuellen Identifikation neuer Wörter wiederholt innerhalb des Textes zu verschieben. Auch innerhalb eines direkt betrachteten Wortes erlauben mittige Fixationsorte eine effizientere Wortverarbeitung als randnahe Blickpositionen (O’Regan, 1981; Brysbaert, Vitu, and Schroyens, 1996). Die meisten Lesemodelle nehmen deshalb an, dass Leser auf die Mitte von Worten zielen (für eine Übersicht siehe Reichle, Rayner, & Pollatsek, 2003). Es zeigt sich aber, dass Landepositionen innerhalb von Wörtern im Lesen von der Distanz der Startposition einer Sakkade zur Mitte des Zielwortes moduliert werden (McConkie, Kerr, Reddix, & Zola, 1988). Noch ist weitgehend unklar, wie Leser die Mitte eines Zielwortes identifizieren. Es fehlt an computationalen Modellen die die sensumotorische Umwandlung der Auswahl eines Zielwortes in eine räumliche Koordinate der Wortmitte beschreiben. Wir präsentieren hier eine Reihe von drei Studien, die darauf abzielen, das Wissen über die Berechnung von Sakkadenzielkoordinaten im Lesen zu erweitern. In einer umfangreichen Korpusanalyse identifizerten wir zunächst das Überspringen von Wörtern als weiteren wichtigen Faktor bei der Sakkadenprogrammierung, der einen ähnlich systematischen und großen Effekt auf die Landepositionen hat wie die Startpositionen der Sakkaden. Anschließend zeigen wir Ergebnisse eines einfachen Sakkadenexperiments, welche nahelegen, dass der Effekt übersprungener Wörter das Ergebnis hoch automatisierter perzeptueller Prozesse ist, die wesentlich auf der Bestimmung von Leerzeichen zwischen Wörtern basieren. Schließlich präsentieren wir ein Bayesianisches Modell der Berechnung von Wortmitten auf der Grundlage der primären sensorischen Erfassungen von Leerzeichen zwischen Wörtern. Wir zeigen, dass das Modell gleichzeitig Effekte der Startposition und des Sakkadentyps erklärt. Unsere Arbeiten zeigen, dass die Berechnung räumlicher Koordinaten für die Sakkadenprogrammierung im Lesen auf einer komplexen Schätzung der Wortmitte anhand unvollständiger sensorischer Informationen beruht, die zu systematischen Abweichungen von der tatsächlichen Wortmitte führt. Unsere Ergebnisse haben wichtige Folgen für gegenwärtige Lesemodelle und für die experimentelle Leseforschung.

We used the SWIFT model of eye-movement control during reading to test these hypotheses and their implications under the assumption of graded parallel processing of all words inside the perceptual span. Specifically, we simulated reading in the boundary paradigm and analysed the effects of denying the model to have valid preview of a parafoveal word n + 2 two words to the right of fixation. Optimizing the model parameters for the valid preview condition only, we obtained span parameters with remarkably realistic estimates conforming to the empirical findings on the size of the perceptual span. More importantly, the SWIFT model generated parafoveal processing up to word n + 2 without fitting the model to such preview effects. Our results suggest that asymmetry and dynamic modulation are plausible properties of the perceptual span in a parallel word-processing model such as SWIFT. Moreover, they seem to guide the flexible distribution of processing resources during reading between foveal and parafoveal words.

A1 - Rapp, Michael Armin T1 - Pavlovian-to-instrumental transfer in alcohol dependence: a pilot study JF - Neuropsychobiology : international journal of experimental and clinical research in biological psychiatry, pharmacopsychiatry, Biological Psychology/Pharmacopsychology and Pharmacoelectroencephalography N2 - Background: Pavlovian processes are thought to play an important role in the development, maintenance and relapse of alcohol dependence, possibly by influencing and usurping ongoing thought and behavior. The influence of pavlovian stimuli on ongoing behavior is paradigmatically measured by pavlovian-to-instrumental transfer (PIT) tasks. These involve multiple stages and are complex. Whether increased PIT is involved in human alcohol dependence is uncertain. We therefore aimed to establish and validate a modified PIT paradigm that would be robust, consistent and tolerated by healthy controls as well as by patients suffering from alcohol dependence, and to explore whether alcohol dependence is associated with enhanced PIT. Methods: Thirty-two recently detoxified alcohol-dependent patients and 32 age- and gender-matched healthy controls performed a PIT task with instrumental go/no-go approach behaviors. The task involved both pavlovian stimuli associated with monetary rewards and losses, and images of drinks. Results: Both patients and healthy controls showed a robust and temporally stable PIT effect. Strengths of PIT effects to drug-related and monetary conditioned stimuli were highly correlated. Patients more frequently showed a PIT effect, and the effect was stronger in response to aversively conditioned CSs (conditioned suppression), but there was no group difference in response to appetitive CSs. Conclusion: The implementation of PIT has favorably robust properties in chronic alcohol-dependent patients and in healthy controls. It shows internal consistency between monetary and drug-related cues. The findings support an association of alcohol dependence with an increased propensity towards PIT.

The fast priming paradigm was previously used to study influences of related versus unrelated primes on the target word. Here, we use this procedure to investigate whether the frequency of the prime word has a direct influence on eye movements during reading when the prime-target relation is not manipulated. We found that with average prime intervals of 32 ms readers made longer single fixation durations on the target word in the low than in the high frequency prime condition. Distributional analyses demonstrated that the effect of prime frequency on single fixation durations occurred very early, supporting theories of immediate cognitive control of eye movements. Finding prime frequency effects only 207 ms after visibility of the prime and for prime durations of 32 ms yields new time constraints for cognitive processes controlling eye movements during reading. Our variant of the fast priming paradigm provides a new approach to test early influences of word processing on eye movement control during reading.

Here, we investigate these effects in the context of sentence processing: targets for retrieval during online sentence processing of English object relative clause constructions differ in the amount of elaboration associated with the target noun phrase, or the homogeneity of superficial features (text color). Experiment 1 shows that greater elaboration for targets during the encoding phase reduces reading times at retrieval sites, but elaboration of non-targets has considerably weaker effects. Experiment 2 illustrates that processing isolated superficial features of target noun phrases-here, a green word in a sentence with words colored white-does not lead to enhanced memory performance, despite triggering longer encoding times. These results are interpreted in the light of the memory models of Nairne, 1990, 2001, 2006, which state that encoding remnants contribute to the set of retrieval cues that provide the basis for similarity-based interference effects.

Two theoretical approaches were contrasted: (1) The process approach predicting that choice deferral varies as a function of information form, and (2) the communication approach predicting an interaction of information form and domain-specific knowledge. Participants were presented with different laptops described in an absolute (e.g. '300 GB hard disc'), evaluative-numerical (e.g. 'hard disc with 30 out of 100 points in an expert rating') or evaluative-verbal (e.g. 'bad hard disc') information form, and they could choose to buy one of the laptops or defer. Domain-specific knowledge was also assessed. In Study 1, evaluative-numerical and evaluative-verbal values led to more deferral in people with high domain-specific knowledge. The pattern for evaluative-numerical and evaluative-verbal values was replicated for a different information organization in Study 2. Study 3 showed that absolute values led to more deferral the less knowledgeable participants were and demonstrated that domain-specific knowledge and deferral were unrelated when absolute and evaluative-verbal values were presented in combination. In sum, the results support the communication approach and have methodological implications for decision research and theoretical implications for understanding choice deferral in real-life decisions.

Participants, whose mean age was 13 years at T1, completed self-report measures of physically and relationally aggressive behavior and indicated their normative approval of both forms of aggression at four data waves separated by 12-month intervals. Boys scored higher than did girls on both forms of aggression, but the gender difference was more pronounced for physical aggression. Physical aggression decreased and relational aggression increased over the four data waves in both gender groups. The normative acceptance of both forms of aggression decreased over time, with a greater decrease for the approval of physical aggression. In both gender groups, normative approval of relational aggression prospectively predicted relational aggression across all data waves, and the normative approval of physical aggression predicted physically aggressive behavior at the second and third data waves. A reciprocal reinforcement of aggressive norms and behavior was found for both forms of aggression. The findings are discussed as supporting a social information processing perspective on developmental patterns of change in physical and relational aggression in adolescence.

Study 1 examined associations among prosocial- and violent-media use, empathy, and helping in samples from seven countries. Prosocial-media use was positively associated with helping. This effect was mediated by empathy and was similar across cultures. Study 2 explored longitudinal relations among prosocial-video-game use, violent-video-game use, empathy, and helping in a large sample of Singaporean children and adolescents measured three times across 2 years. Path analyses showed significant longitudinal effects of prosocial- and violent-video-game use on prosocial behavior through empathy. Latent-growth-curve modeling for the 2-year period revealed that change in video-game use significantly affected change in helping, and that this relationship was mediated by change in empathy.

In the light of the unique history of American Indians, we investigated the relationship between identification with the American Indian ingroup, orientation toward the dominant White American culture ( in terms of showing behavior typical for White mainstream culture as well as positive attitudes and feelings of belonging to White American culture), and self-efficacy and learned helplessness as indicators of psychological well-being. Structural equation analyses with an adolescent and an adult sample revealed a positive relationship between ethnic identity and self-efficacy but no link with learned helplessness. The tendency to show behavior typical for White mainstream culture was associated with higher self-efficacy in both samples and with lower helplessness in the adult subsample. White American orientation in the form of positive attitudes and sense of belonging were associated with higher helplessness in both samples and with lower self-efficacy among adults.

In evaluating the evidence, the authors portray a biased picture of the current state of knowledge about media violence effects. They fail to distinguish between aggression and violence and between everyday and clinical forms of aggression. Furthermore, they misrepresent key constructs, such as mediation, moderation, and external validity, to discredit methodologies used to assess aggression and media violence use. The paper moves the debate backward rather than forward, falling behind existing meta-analytic studies that consider a much wider and more balanced range of studies.

T1 - Processing speed enhances model-based over model-free reinforcement learning in the presence of high working memory functioning JF - Frontiers in psychology N2 - Theories of decision-making and its neural substrates have long assumed the existence of two distinct and competing valuation systems, variously described as goal-directed vs. habitual, or, more recently and based on statistical arguments, as model-free vs. model-based reinforcement-learning. Though both have been shown to control choices, the cognitive abilities associated with these systems are under ongoing investigation. Here we examine the link to cognitive abilities, and find that individual differences in processing speed covary with a shift from model-free to model-based choice control in the presence of above-average working memory function. This suggests shared cognitive and neural processes; provides a bridge between literatures on intelligence and valuation; and may guide the development of process models of different valuation components. Furthermore, it provides a rationale for individual differences in the tendency to deploy valuation systems, which may be important for understanding the manifold neuropsychiatric diseases associated with malfunctions of valuation.

T1 - Model-based and model-free decisions in alcohol dependence JF - Neuropsychobiology : international journal of experimental and clinical research in biological psychiatry, pharmacopsychiatry, Biological Psychology/Pharmacopsychology and Pharmacoelectroencephalography N2 - Background: Human and animal work suggests a shift from goal-directed to habitual decision-making in addiction. However, the evidence for this in human alcohol dependence is as yet inconclusive. Methods: Twenty-six healthy controls and 26 recently detoxified alcohol-dependent patients underwent behavioral testing with a 2-step task designed to disentangle goal-directed and habitual response patterns. Results: Alcohol-dependent patients showed less evidence of goal-directed choices than healthy controls, particularly after losses. There was no difference in the strength of the habitual component. The group differences did not survive controlling for performance on the Digit Symbol Substitution Task. Conclusion: Chronic alcohol use appears to selectively impair goal-directed function, rather than promoting habitual responding. It appears to do so particularly after nonrewards, and this may be mediated by the effects of alcohol on more general cognitive functions subserved by the prefrontal cortex.

Representative data on perception of body signals and its emotional correlates in children is lacking. Therefore, the present study investigated the cardiac sensitivity of 1,350 children between 6 and 11 years of age in a heartbeat perception task. Our main findings demonstrated the distribution of cardiac sensitivity in children as well as associations with interpersonal emotional intelligence and adaptability. Furthermore, independent of body mass index, boys showed a significantly higher cardiac sensitivity than girls. We conclude that cardiac sensitivity in children appears to show weaker but similar characteristics and relations to emotional parameters as found in adults, so that a dynamic developmental process can be assumed.

Recent research suggests that the experience of time emerges from emotional and interoceptive (bodily) states as processed in the insular cortex. Whether there is an interaction between the conscious awareness of interoceptive states and time distortions induced by emotions has rarely been investigated so far. We aimed to address this question by the use of a retrospective time estimation task comparing two groups of participants. One group had a focus on interoceptive states and one had a focus on exteroceptive information while watching film clips depicting fear, amusement and neutral content. Main results were that attention to interoceptive processes significantly affected subjective time experience. Fear was accompanied with subjective time dilation that was more pronounced in the group with interoceptive focus, while amusement led to a quicker passage of time which was also increased by interoceptive focus. We conclude that retrospective temporal distortions are directly influenced by attention to bodily responses. These effects might crucially interact with arousal levels. Sympathetic nervous system activation affecting memory build-up might be the decisive factor influencing retrospective time judgments. Our data substantially extend former research findings underscoring the relevance of interoception for the effects of emotional states on subjective time experience.

This paper documents the available evidence on the prevalence of sexual aggression perpetration and victimization from 27 EU countries, established as part of the Youth Sexual Aggression and Victimization (Y-SAV) project. A total of N = 113 studies were identified through a systematic review of the literature and consultations with experts in each country. Despite differences in the number of available studies, methodology, and sample composition, the review shows substantial prevalence rates of sexual aggression perpetration and victimization across Europe. A wide variation was found, both within and between countries. The lifetime prevalence rates of female sexual victimization, excluding childhood sexual abuse, ranged from 9 to 83%, the rates of male sexual victimization ranged from 2 to 66%, the rates of male sexual aggression ranged from 0 to 80%, and the range of female sexual aggression ranged from 0.8 to 40%. One-year prevalence rates showed a similar variability. Conceptual and methodological problems in the database are discussed, and an outline is presented for a more harmonized approach to studying the scale of sexual aggression among young people in Europe.
