Contrary to the commonly accepted view that high foveal load leads to reduced parafoveal processing efficiency, results of the present study showed that increasing foveal visual (but not linguistic) processing load actually increased the amount of parafoveal information acquired, presumably due to the fact that longer fixation duration on the pretarget word provided more time for parafoveal processing of the target word. It is therefore proposed in the present study that foveal linguistic processing load is not the only factor that determines parafoveal processing; preview time (afforded by foveal word visual processing load) may jointly influence parafoveal processing.

We calculated intertrial coherence, topographic consistency and low frequency amplitude variability during target P300 in a continuous performance test in 263 15-year-olds from a cohort with psychosocial and biological risk factors. Topographic consistency and low frequency amplitude variability predicted reaction time fluctuations (RTSD) in a linear model. Higher RTSD was only associated with higher psychosocial adversity in the presence of the homozygous 6R-10R dopamine transporter haplotype. We propose that topographic variability of single trial P300 reflects noise as well as variability in evoked cortical activation patterns.

We assessed BE, internalizing symptoms and psychological factors in 1039 adolescents from a community sample by self-report. Using multinomial logistic regression and controlling for measured height and weight, we compared adolescents with BE with individuals from a healthy control group and adolescents reporting internalizing symptoms. Individuals from the BE-group reported a greater lack of interoceptive awareness and higher body dissatisfaction than individuals from the healthy control group. Additionally, we found a significant interaction between gender and body dissatisfaction. Internalization of the societal body ideal was related to BE when compared to internalizing symptoms. Results suggest, that the lack of interoceptive awareness and body dissatisfaction display substantial associations with BE, and that the latter effect is especially strong in boys. The internalization of societal standards of beauty emerged as a BE-specific factor and this finding emphasizes the role of the societal body ideal in the nature of eating pathology in boys and in girls.

At age 25 years, voxel-based morphometry was applied to study brain volume differences. Poverty (0 = non-exposed (N = 134), I = exposed (N = 33)) and smoking during pregnancy were determined using a standardized parent interview, and information on maternal responsiveness was derived from videotaped mother infant interactions at the age of 3 months. CD symptoms were assessed by diagnostic interview from 8 to 19 years of age. Information on life stress was acquired at each assessment and childhood maltreatment was measured using retrospective self-report at the age of 23 years. Analyses were adjusted for sex, parental psychopathology and delinquency, obstetric adversity, parental education, and current poverty. Individuals exposed to early life poverty exhibited a lower OFC volume. Moreover, we replicated previous findings of increased CD symptoms as a consequence of childhood poverty. This effect proved statistically mediated by OFC volume and exposure to life stress and smoking during pregnancy, but not by childhood maltreatment and maternal responsiveness.

We hypothesized that lower hot and cool EF predicts a stronger increase in eating styles related to greater weight gain (food approach) and a weaker increase in eating styles related to less weight gain (food avoidance) over a 1-year period. Hot (delay of gratification, affective decision-making) and cool (attention shifting, inhibition, working memory updating) EF was assessed experimentally in a sample of 1657 elementary-school children (German school classes 1-3) at two time points, approximately one year apart. The children's food-approach and food-avoidance behavior was rated mainly via parent questionnaires at both time points. As expected, lower levels of hot and cool EF predicted a stronger increase in several food-approach eating styles across a 1-year period, mainly in girls. Unexpectedly, poorer performance on the affective decision-making task also predicted an increase in certain food-avoidance styles, namely, slowness in eating and satiety responsiveness, in girls. Results implicate that lower EF is not only seen in eating-disordered or obese individuals but also acts as a risk factor for an increase in particular eating styles that play a role in the development of weight problems in children.

Correlations revealed that the most caloric products and those anticipated to be creamier were expected to be more filling and hunger suppressing than the products with lower energy content and expected to be less creamy. Total energy was the best predictor of expected satiation and satiety. We observed that beverage products were expected to be similarly satiating as food products (including liquid, solid and semi-solids) with a similar total energy content and expected creaminess. On the other hand, products expected to be less salty and thick were expected to be most thirst-quenching, and these tended to be beverage products, regardless of their total energy content. These results are in line with emerging evidence suggesting that certain sensory cues associated with nutrients can be used to estimate the satiating power of other foods, including beverages. Beverages are expected to be uniquely thirst-quenching, but are not always expected to have a low satiety-value. (C) 2015 Elsevier Ltd.

By simultaneously recording eye movements and the voice during reading aloud, we obtained an output measure that constrains the length of time spent on cognitive processing. Here we investigate the dynamics of the eye-voice span (EVS), the distance between eye and voice. We show that the EVS is regulated immediately during fixation of a word by either increasing fixation duration or programming a regressive eye movement against the reading direction. EVS size at the beginning of a fixation was positively correlated with the likelihood of regressions and refixations. Regression probability was further increased if the EVS was still large at the end of a fixation: if adjustment of fixation duration did not sufficiently reduce the EVS during a fixation, then a regression rather than a refixation followed with high probability. We further show that the EVS can help understand cognitive influences on fixation duration during reading: in mixed model analyses, the EVS was a stronger predictor of fixation durations than either word frequency or word length. The EVS modulated the influence of several other predictors on single fixation durations (SFDs). For example, word-N frequency effects were larger with a large EVS, especially when word N-1 frequency was low. Finally, a comparison of SFDs during oral and silent reading showed that reading is governed by similar principles in both reading modes, although EVS maintenance and articulatory processing also cause some differences.

Methods/Design: In a multicenter, prospective, parallel group, randomized controlled superiority trial, 226 obese children and adolescents aged 8 to 16 years will be allocated either to a newly developed computer-training program to improve their self-regulation abilities or to a placebo control group. Randomization occurs centrally and blockwise at a 1:1 allocation ratio for each center.

Observer-blind assessments of outcome variables take place at four times: at the beginning of the rehabilitation (pre), at the end of the training in the rehabilitation (post), and 6 and 12 months post-rehabilitation intervention. The primary outcome is the course of BMI-SDS over 1 year after the end of the inpatient rehabilitation. Secondary endpoints are the self-regulation skills.

Here, we develop a dynamical model of saccadic selection that accurately predicts the distribution of gaze positions as well as spatial clustering along individual scanpaths.

We addressed this hypothesis by analyzing spontaneous eye movements during mental arithmetic. Participants solved verbally presented arithmetic problems (e.g., 2 + 7, 8-3) aloud while looking at a blank screen. We found that eye movements reflected spatial biases in the ongoing mental operation: Gaze position shifted more upward when participants solved addition compared to subtraction problems, and the horizontal gaze position was partly determined by the magnitude of the operands.

Functional magnetic resonance imaging during an emotional face-matching task was performed in 153 healthy young adults (66 males) from a high-risk community sample followed since birth. Voxel-based morphometry was applied to study structural alterations and DNA was genotyped for FKBP5 rs1360780.

Depression was assessed by the Beck Depression Inventory. There was a main effect of FKBP5 on the left amygdala, with T homozygotes showing the highest activity, largest volume and increased coupling with the left hippocampus and the orbitofrontal cortex (OFC). Moreover, amygdala-OFC coupling proved to be associated with depression in this genotype.

However, questions of whether emotion recognition deficits are present and how they are reflected have only been sparsely investigated to date. Methods: Therefore, the present study included 33 overweight and obese as well as 33 normal weight elementary school children between six and ten years that were matched for sex, age and socioeconomic status. Participants were shown different emotional faces of a well-validated set of stimuli on a computer screen, which they categorized and then rated on an emotional intensity level. Key measures were categorization performance along with reaction times and emotional intelligence as well as emotional eating questionnaire ratings. Results: Overweight children exhibited lower categorization accuracy as well as longer reaction times as compared to normal weight children, while no differences in intensity ratings occurred. Reaction time to neutral facial expressions was negatively related to intrapersonal and interpersonal emotional intelligence and emotional eating correlated negatively with accuracy for recognizing sad expressions. Conclusion: Facial emotion decoding difficulties seem to be of importance in overweight and obese children and deserve further consideration in terms of their exact impact on social functioning as well as on the maintenance of elevated body weight during child development.

Aim of this study was to elucidate early mechanisms relating to dysregulation in later life using data from an epidemiological cohort study on the long-term outcome of early risk factors from birth to adulthood. At age 3 months, mothers and infants were videotaped during a nursing and playing situation. Maternal responsiveness was evaluated by trained raters. Infant regulatory problems were assessed on the basis of a parent interview and direct observation by trained raters. At age 8 and 11 years, 290 children (139 males) were rated on the Child Behavior Checklist (CBCL). Additionally, participants were genotyped for the dopamine D4 receptor (DRD4) exon 3 VNTR polymorphism. A significant three-way interaction between maternal responsiveness, DRD4 genotype and infant regulatory problems was detected predicting the CBCL-dysregulation profile (CBCL-DP). Carriers of the DRD4 7r allele with regulatory problems at age 3 months showed significantly more behavior problems associated with the CBCL-DP during childhood when exposed to less maternal responsiveness. In contrast, no effect of maternal responsiveness was observed in DRD4 7r carriers without infant regulatory problems and in non-carriers of the DRD4 7r allele. This prospective longitudinal study extends earlier findings regarding the association of the CBCL-DP with early parenting and later psychopathology, introducing both DRD4 genotype and infant regulatory problems as important moderators.

We created the Potsdam-Allahabad Hindi Eyetracking Corpus by recording eye-movement data from 30 participants at the University of Allahabad, India. The target stimuli were 153 sentences selected from the beta version of the Hindi-Urdu treebank. We find that word- or low-level predictors (syllable length, unigram and bigram frequency) affect first-pass reading times, regression path duration, total reading time, and outgoing saccade length. An increase in syllable length results in longer fixations, and an increase in word unigram and bigram frequency leads to shorter fixations. Longer syllable length and higher frequency lead to longer outgoing saccades. We also find that two predictors of sentence comprehension difficulty, integration and storage cost, have an effect on reading difficulty. Integration cost (Gibson, 2000) was approximated by calculating the distance (in words) between a dependent and head; and storage cost (Gibson, 2000), which measures difficulty of maintaining predictions, was estimated by counting the number of predicted heads at each point in the sentence. We find that integration cost mainly affects outgoing saccade length, and storage cost affects total reading times and outgoing saccade length. Thus, word-level predictors have an effect in both early and late measures of reading time, while predictors of sentence comprehension difficulty tend to affect later measures. This is, to our knowledge, the first demonstration using eye-tracking that both integration and storage cost influence reading difficulty.}, language = {en} } @misc{Fengler2015, author = {Fengler, Anja}, title = {How the brain attunes to sentence processing}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-85820}, pages = {XVI, 208}, year = {2015}, abstract = {While children acquire new words and simple sentence structures extremely fast and without much effort, the ability to process complex sentences develops rather late in life. Although the conjoint occurrence between brain-structural and brain-functional changes, the decrease of plasticity, and changes in cognitive abilities suggests a certain causality between these processes, concrete evidence for the relation between brain development, language processing, and language performance is rare. Therefore, the current dissertation investigates the tripartite relationship between behavior (in the form of language performance and cognitive maturation as prerequisite for language processing), brain structure (in the form of gray matter maturation), and brain function (in the form of brain activation evoked by complex sentence processing). Previous developmental studies indicate a missing increase of activation in accordance to sentence complexity (functional selectivity) in language-relevant brain areas in children. To determine the factors contributing to the functional development of language-relevant brain areas, different methodologies and data acquisition techniques were used to investigate the processing of center-embedded sentences in 5- and 6-year-old children, 7- and 8-year-old children, and adults. Behavioral results indicate that children between 5 and 8 years show difficulties in processing double embedded sentences and that their performance for these type of sentences is positively correlated with digit span. In 7- and 8-year-old children, it was found that especially the processing of long-distance relations between the initial phrase and its corresponding verb appears to be associated with the subject's verbal working memory capacity. In contrast, children's performance for double embedded sentences in the younger age group positively correlated with their performance in a standardized sentence comprehension test. This finding supports the hypothesis that processing difficulties in this age group may be mainly attributed to difficulties in processing case marking information. These findings are discussed with respect to current accounts of language and working memory development. A second study aimed at investigating the structural maturation of brain areas involved in sentence comprehension. To do this, whole-brain magnetic resonance images from 59 children between 5 and 8 years were collected and children's gray matter was analyzed by using voxel-based morphometry. Children's grammatical proficiency was assessed by a standardized sentence comprehension test. A confirmatory factory analysis corroborated a grammar-relevant and a verbal working memory-relevant factor underlying the measured performance. While children's ability to assign thematic roles is positively correlated with gray matter probability (GMP) in the left inferior temporal gyrus and the left inferior frontal gyrus, verbal working memory-related performance is positively correlated with GMP in the left parietal operculum extending into the posterior superior temporal gyrus. These areas have been previously shown to be differentially engaged in adults' complex sentence processing. Thus, the findings of the second study suggest a specific correspondence between children's GMP in language-relevant brain regions and differential cognitive abilities which underlie complex sentence comprehension. In a third study, functional brain activity during the processing of center-embedded sentences was investigated in three different age groups (5-6 years, 7-8 years, and adults). Although all age groups engage a qualitatively comparable network of the left pars opercularis (PO), the left inferior parietal lobe extending into the posterior superior temporal gyrus (IPL/pSTG), the supplementary motor area (SMA) and the cerebellum, functional selectivity of these regions was only observable in adults. However, functional activation of the language-related regions (PO and IPL/pSTG) predicted sentence comprehension performance for all age groups. To solve the question of the complex interplay between different maturational factors, a fourth study analyzed the predictive power of gray matter probability, verbal working memory capacity, and behavioral differences in performance for simple and complex sentence for the functional selectivity of each activated region. These analyses revealed that the establishment of the adult-like functional selectivity for complex sentences is predicted by a reduction of the left PO's gray matter probability across age groups while that of the IPL/pSTG is additionally predicted by verbal working memory capacity. Taken all findings together, the current thesis provides evidence that both structural brain maturation and verbal working memory expansion provide the basis for the emergence of functional selectivity in language-related brain regions leading to more efficient sentence processing during development.}, language = {en} } @article{GottwaldElsnerPollatos2015, author = {Gottwald, Janna M. and Elsner, Birgit and Pollatos, Olga}, title = {Good is up-spatial metaphors in action observation}, series = {Frontiers in psychology}, volume = {6}, journal = {Frontiers in psychology}, publisher = {Frontiers Research Foundation}, address = {Lausanne}, issn = {1664-1078}, doi = {10.3389/fpsyg.2015.01605}, pages = {10}, year = {2015}, abstract = {Positive objects or actions are associated with physical highness, whereas negative objects or actions are related to physical lowness. Previous research suggests that metaphorical connection ("good is up" or "bad is down") between spatial experience and evaluation of objects is grounded in actual experience with the body. Prior studies investigated effects of spatial metaphors with respect to verticality of either static objects or self-performed actions. By presenting videos of object placements, the current three experiments combined vertically-located stimuli with observation of vertically-directed actions. As expected, participants' ratings of emotionally-neutral objects were systematically influenced by the observed vertical positioning, that is, ratings were more positive for objects that were observed being placed up as compared to down. Moreover, effects were slightly more pronounced for "bad is down," because only the observed downward, but not the upward, action led to different ratings as compared to a medium-positioned action. Last, some ratings were even affected by observing only the upward/downward action, without seeing the final vertical placement of the object. Thus, both, a combination of observing a vertically-directed action and seeing a vertically-located object, and observing a vertically-directed action alone, affected participants' evaluation of emotional valence of the involved object.

The present thesis builds upon that work, assessing to what extent coregistration can be helpful for sentence processing research. In the first study, we explore how well coregistration is suited to study subtle effects common to psycholinguistic experiments by investigating the effect of distance on dependency resolution. The results demonstrate that researchers must improve the signal-to-noise ratio to uncover more subdued effects in coregistration.

Each participant read three short case scenarios (vignettes) and completed items pertaining to the female victim and male perpetrator. The vignettes were systematically varied with regard to the type of crime that was committed (rape or robbery), the perpetrator's coercive strategy (physical force or exploiting the victim's alcohol-induced defenselessness), and the victim-perpetrator relationship prior to the incident (stranger, acquaintance, or ex-partner). Furthermore, participant gender and acceptance of rape myths (beliefs that justify or trivialize sexual violence) were taken into account. One half of the participants completed the rape myth acceptance (RMA) scales first and then received the vignettes, while the other half were given the vignettes first and then completed the RMA scales. As expected, more blame was attributed to victims of rape than to victims of robbery. Conversely, perpetrators of rape were blamed less than perpetrators of robbery. The more participants endorsed rape myths, the more blame was attributed to the victim and the less blame was attributed to the perpetrators. Increasing levels of RMA were associated with an increase in victim blame (VB) in both rape and robbery cases, but the increase in rape VB was significantly more pronounced than in robbery VB. Increasing RMA was associated with an attenuation of perpetrator blame (PB) that was more pronounced for rape than for robbery cases, but the difference was not significant. As expected, victims of rape were blamed more when the perpetrator exploited their defenselessness due to alcohol intoxication than when they were overpowered by physical force. Contrary to the hypothesis, this was also true for robbery victims. Rape victims who knew their attacker (ex-partner or acquaintance) were blamed more than victims who were assaulted by strangers. Contrary to the hypothesis, robbery victims who were assaulted by an ex-partner were blamed more than acquaintance or stranger robbery victims. As predicted, the closer the relationship between victim and perpetrator, the less blame was attributed to perpetrators of rape while this factor had no effect on PB in robbery cases. Men compared to women attributed more blame to the victims and less blame to the perpetrators. As expected, these gender differences in blame attributions were partially mediated by gender differences in RMA: After RMA was taken into account, the gender differences disappeared nearly completely for VB and were significantly reduced in PB. The order of presentation of the vignettes and the RMA measures was systematically varied to test the causal influence of RMA on rape blame attributions. The hypothesis that RMA causes VB and PB in rape cases (as opposed to the other way around or both are caused by a third variable) was not supported. Possible reasons for this failed manipulation and its implications for the mediation model are discussed. With regard to blame attribution in rape cases, the present results match what was expected from previous studies which were mainly conducted in "Western" countries like the United States, the United Kingdom, or Germany. The present results support the notion that the victim-perpetrator relationship and the victim's alcohol consumption are cross-culturally stable factors for blame attribution in rape cases. It was expected that blame attribution in robbery cases would be unaffected by the perpetrator's coercive strategy and the victim-perpetrator relationship, but the results were inconsistent. One unexpected effect is particularly noteworthy: When the perpetrator used physical force, more blame was attributed to rape than to robbery victims, but intoxicated victims were blamed more and almost equally so for both types of crime. Perpetrators who exploited drunk victims were blamed less in both rape and robbery cases. These results contradict German results collected with the German version of the same instruments (Bieneck \& Krah{\´e}, 2011). Turkey is a Muslim country and alcohol is surrounded by a certain taboo. Possibly, the results reflect a cultural difference in that intoxicated victims are generally blamed more for their victimization and this factor is not limited to rape cases.}, language = {en} } @article{CoscoBrehmeGrigorutaetal.2015, author = {Cosco, Theodore D. and Brehme, David F. and Grigoruta, Nora and Kaufmann, Lisa-Katrin and Lemsalu, Liis and Meex, Ruth and Schuurmans, Angela A.

Results: Controlling for baseline levels and various demographic covariates, media violence use at T2, T3, and T4 and self-reported physical aggression at T3 were significantly lower in the intervention group, and the indirect path from the intervention to T3 aggression via T2 media violence use was significant. Lower T2 media violence use predicted lower T3 normative acceptance of aggression among participants with lower initial aggression.

One factor known to influence fixation durations in reading is the preprocessing of words in parafoveal vision. Here we investigated whether individual differences in reading speed or the amount of information extracted from upcoming words (the preview benefit) can be explained by basic differences in extrafoveal vision-i.e., the ability to recognize peripheral letters with or without the presence of flanking letters. Forty participants were given an adaptive test to determine their eccentricity thresholds for the identification of letters presented either in isolation (extrafoveal acuity) or flanked by other letters (crowded letter recognition). In a separate eye-tracking experiment, the same participants read lists of words from left to right, while the preview of the upcoming words was manipulated with the gaze-contingent moving window technique. Relationships between dependent measures were analyzed on the observational level and with linear mixed models. We obtained highly reliable estimates both for extrafoveal letter identification (acuity and crowding) and measures of reading speed (overall reading speed, size of preview benefit). Reading speed was higher in participants with larger uncrowded windows. However, the strength of this relationship was moderate and it was only observed if other sources of variance in reading speed (e.g., the occurrence of regressive saccades) were eliminated. Moreover, the size of the preview benefit-an important factor in normal reading-was larger in participants with better extrafoveal acuity.

Whilst there is evidence that body-dissatisfied women and those suffering from disordered eating show a negative attentional bias towards their own unattractive body parts and others' attractive body parts, little is known about visual attention patterns in the area of obesity and with respect to males. Since eating disorders and obesity share common features in terms of distorted body image and body dissatisfaction, the aim of this study was to examine whether overweight men and women show a similar attentional bias. Methods/Design We analyzed eye movements in 30 overweight individuals (18 females) and 28 normal-weight individuals (16 females) with respect to the participants' own pictures as well as gender- and BMI-matched control pictures (front and back view). Additionally, we assessed body image and disordered eating using validated questionnaires. Discussion The overweight sample rated their own body as less attractive and showed a more disturbed body image. Contrary to our assumptions, they focused significantly longer on attractive compared to unattractive regions of both their own and the control body. For one's own body, this was more pronounced for women. A higher weight status and more frequent body checking predicted attentional bias towards attractive body parts.

Whilst there is evidence that body-dissatisfied women and those suffering from disordered eating show a negative attentional bias towards their own unattractive body parts and others' attractive body parts, little is known about visual attention patterns in the area of obesity and with respect to males. Since eating disorders and obesity share common features in terms of distorted body image and body dissatisfaction, the aim of this study was to examine whether overweight men and women show a similar attentional bias. Methods/Design We analyzed eye movements in 30 overweight individuals (18 females) and 28 normalweight individuals (16 females) with respect to the participants' own pictures as well as gender- and BMI-matched control pictures (front and back view). Additionally, we assessed body image and disordered eating using validated questionnaires. Discussion The overweight sample rated their own body as less attractive and showed a more disturbed body image. Contrary to our assumptions, they focused significantly longer on attractive compared to unattractive regions of both their own and the control body. For one's own body, this was more pronounced for women. A higher weight status and more frequent body checking predicted attentional bias towards attractive body parts.

We aimed to investigate whether NR3C1 methylation changes are similarly associated with externalizing disorders such as aggressive behavior and conduct disorder. NR3C1 exon 1F methylation was analyzed in young adults with a lifetime diagnosis of an externalizing disorder (N = 68) or a depressive disorder (N = 27) and healthy controls (N = 124) from the Mannheim Study of Children at Risk. The externalizing disorders group had significantly lower NR3C1 methylation levels than the lifetime depressive disorder group (p = 0.009) and healthy controls (p = 0.001) This report of lower methylation levels in NR3C1 in externalizing disorders may indicate a mechanism through which the differential development of externalizing disorders as opposed to depressive disorders might occur.}, language = {en} } @article{KuhlmannBuergerEsseretal.2015, author = {Kuhlmann, Sophie Merle and B{\"u}rger, Arne and Esser, G{\"u}nter and Hammerle, Florian}, title = {A mindfulness-based stress prevention training for medical students (MediMind): study protocol for a randomized controlled trial}, series = {Trials}, volume = {16}, journal = {Trials}, publisher = {BioMed Central}, address = {London}, issn = {1745-6215}, doi = {10.1186/s13063-014-0533-9}, pages = {11}, year = {2015}, abstract = {Background: Medical training is very demanding and associated with a high prevalence of psychological distress.

More recently, similar contextual influences have been documented in the domain of number knowledge. Here we show such context dependency in a length production task. Adult participants saw single digit addition problems of the form n1 + n2 and produced the sum by changing bi-directionally the length of a horizontally extended line, using radially arranged buttons. We found that longer lines were produced when n1 < n2 compared to n1 > n2 and that unit size increased with result size. Thus, the mathematical axioms of commutativity and identity do not seem to hold in mental addition. We discuss implications of these observations for our understanding of cognitive mechanisms involved in mental arithmetic and for situated cognition generally.}, language = {en} }
