Recent embodied theories suggest that analog number representations are based on previous sensory experiences and constitute therefore a common magnitude metric shared by multiple domains. Here we demonstrate the existence of a cross-modal semantic distance effect between symbolic and tactile numerosities. Participants received tactile stimulations of different amounts of fingers while reading Arabic digits and indicated verbally whether the amount of stimulated fingers was different from the simultaneously presented digit or not. The larger the semantic distance was between the two numerosities, the faster and more accurate participants made their judgments. This cross-modal numerosity distance effect suggests a direct connection between tactile sensations and the concept of numerical magnitude. A second experiment replicated the interaction between symbolic and tactile numerosities and showed that this effect is not modulated by the participants' finger counting habits. Taken together, our data provide novel evidence for a shared metric for symbolic and tactile numerosities as an instance of an embodied representation of numbers.}, language = {en} } @article{EngelmannVasishthEngbertetal.2013, author = {Engelmann, Felix and Vasishth, Shravan and Engbert, Ralf and Kliegl, Reinhold}, title = {A framework for modeling the interaction of syntactic processing and eye movement control}, series = {Topics in cognitive science}, volume = {5}, journal = {Topics in cognitive science}, number = {3}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {1756-8757}, doi = {10.1111/tops.12026}, pages = {452 -- 474}, year = {2013}, abstract = {We explore the interaction between oculomotor control and language comprehension on the sentence level using two well-tested computational accounts of parsing difficulty.

We built a reading model that could initiate short Time Out regressions (Mitchell, Shen, Green, \& Hodgson, 2008) that compensate for slow postlexical processing. This simple interaction enabled the model to predict the re-reading of words based on parsing difficulty. The model was evaluated in different configurations on the prediction of frequency effects on the Potsdam Sentence Corpus. The extension of EMMA with postlexical processing improved its predictions and reproduced re-reading rates and durations with a reasonable fit to the data.

We tested a structural equation model for different feeding strategies. Results: In addition to an expected direct association between the mother's and child's emotional eating, the maternal feeding strategies are related to the child's eating behavior. A higher maternal restriction of food or its monitoring was associated with a higher level of children's emotional eating, while allowing the child more control about their eating was linked to less pronounced emotional eating behavior.

Methods: Data were collected as part of an epidemiological cohort study on the outcome of early risk factors followed since birth. At age 19 years, 268 young adults (126 males, 142 females) were genotyped for PER2 rs56013859 and were administered a 45-day alcohol timeline follow-back interview and the Alcohol Use Disorders Identification Test (AUDIT). Life stress was assessed as the number of severe negative life events during the past four years reported in a questionnaire and validated by interview. Results: Individuals with the minor G allele of rs56013859 were found to be less engaged in alcohol use, drinking at only 72\% of the days compared to homozygotes for the major A allele. Moreover, among regular drinkers, a gene x environment interaction emerged (p = .020). While no effects of genotype appeared under conditions of low stress, carriers of the G allele exhibited less hazardous drinking than those homozygous for the A allele when exposed to high stress.

Psychosocial dysfunctioning of children, such as increased stress experience, is a burden for children and parents and complicates clinical management. Additional comorbid disorders may develop. To minimize the onset of such disorders, treatment at an early stage and taking psychosocial aspects into consideration is strongly recommended. Through this approach, the cognitive-behavioral, child-centered group program 'Stop the pain with Happy-Pingu' was developed, applied, and subsequently evaluated. What is the psychosocial situation of the affected children? Can the cognitive-behavioral group program be applied to improve psychosocial limitations? Method: The cognitive-behavioral group program comprises 6 weekly sessions for children and 1 single meeting for parents. In a randomized controlled study, the program was evaluated with 29 children aged between 6 and 12 years. The evaluation was based on a comparison between the intervention group (IG) and the waiting list control group (WLC), measured at 3 measurement points: T1 (pre), T2 (post), and T3 (3-month follow-up). Results: Emotional problems in particular can emerge in children with CAP. The program was well received, with a high level of participation through to completion. The results demonstrate that children participating in the IG experience significant stress reduction and improved psychosocial functioning compared to children participating in the WLC. The effect sizes range from medium to high. Conclusions: Drawing upon the above findings, multimodal cognitive-behavioral techniques appear to be suitable to successfully treat children with CAP.

Using gaze-contingent displays, we applied high-pass or low-pass filters to either the central or the peripheral visual field and compared eye-movement patterns with an unfiltered control condition. In contrast with predictions from functional segregation, fixation durations were unaffected when the critical information for vision was strongly attenuated (foveal low-pass and peripheral high-pass filtering); fixation durations increased, however, when useful information was left mostly intact by the filter (foveal high-pass and peripheral low-pass filtering). These patterns of results are difficult to explain under the assumption that fixation durations are controlled by foveal processing difficulty. As an alternative explanation, we developed the hypothesis that the interaction of foveal and peripheral processing controls fixation duration. To investigate the viability of this explanation, we implemented a computational model with two compartments, approximating spatial aspects of processing by foveal and peripheral activations that change according to a small set of dynamical rules.

Here, we contribute to this issue by contrasting regular (regular stem, regular suffix) with semi-irregular (regular stem, irregular suffix) and irregular (irregular stem, irregular suffix) participle formation in a visual priming experiment on German verb inflection. We measured ERPs and RTs and manipulated the inflectional and meaning relatedness between primes and targets. Inflected verb targets (e. g., leite, "head") were preceded either by themselves, by their participle (geleitet, "headed"), by a semantically related verb in the same inflection as the target (fuhre, "guide") or in the participle form (gefuhrt, "guided"), or by an unrelated verb in the same inflection (nenne, "name"). Results showed that behavioral and ERP priming effects were gradually affected by verb regularity. Regular participles produced a widely distributed frontal and parietal effect, irregular participles produced a small left parietal effect, and semi-irregular participles yielded an effect in-between these two in terms of amplitude and topography. The behavioral and ERP effects further showed that the priming because of participles differs from that because of semantic associates for all verb types. These findings argue for a single processing system that generates participle priming effects for regular, semi-irregular, and irregular verb inflection. Together, the findings provide evidence that the linguistic categories of verb inflection are processed continuously. We present a single-system model that can adequately account for such graded effects.}, language = {en} } @article{GrossWarschburger2013, author = {Gross, Martina and Warschburger, Petra}, title = {Evaluation of a cognitive-behavioral pain management program for children with chronic abdominal pain - a randomized controlled study}, series = {International journal of behavioral medicine : the official journal of the International Society of Behavioral Medicine}, volume = {20}, journal = {International journal of behavioral medicine : the official journal of the International Society of Behavioral Medicine}, number = {3}, publisher = {Springer}, address = {New York}, issn = {1070-5503}, doi = {10.1007/s12529-012-9228-3}, pages = {434 -- 443}, year = {2013}, abstract = {Background Chronic abdominal pain (CAP) in childhood is widely prevalent and has adverse effects on mental health and quality of life.

Purpose We hypothesized that the training would significantly reduce pain symptoms (frequency, duration, intensity, and pain-related impairment) and increase health-related quality of life compared to wait-list controls, with improvement seen both at the end of treatment and at a 3-month follow-up. Method In all, 29 children were randomized into two groups: 15 in the intervention group (IG) and 14 as the wait-list controls (WLC). An intent-to-treat analysis was performed using two-factorial multivariate analyses of variance with repeated measures. Results Children in the IG experienced both a reduction in pain (primary outcome) and an improvement in health-related quality of life (secondary outcome) as compared to the WLC.

In addition, dyslexics were less efficient in parafoveal processing in these RAN tasks. Since the two RAN tasks required the same phonological output and on the assumption that naming dice is less practiced than naming digits in general, the results suggest that the translation of alphanumeric visual symbols into phonological codes is less efficient in dyslexic children.

If the parafoveal preview of the next word is suppressed, reading is less efficient. A linear mixed model (LMM) reanalysis of McDonald (2006) confirmed his observation that preview benefit may be limited to parafoveal words that have been selected as the saccade target. Going beyond the original analyses, in the same LMM, we examined how the preview effect (i.e., the difference in single-fixation duration, SFD, between random-letter and identical preview) depends on the gaze duration on the pretarget word and on the amplitude of the saccade moving the eye onto the target word. There were two key results: (a) The shorter the saccade amplitude (i.e., the larger preview space), the shorter a subsequent SFD with an identical preview; this association was not observed with a random-letter preview. (b) However, the longer the gaze duration on the pretarget word, the longer the subsequent SFD on the target, with the difference between random-letter string and identical previews increasing with preview time. A third patternincreasing cost of a random-letter string in the parafovea associated with shorter saccade amplitudeswas observed for target gaze durations. Thus, LMMs revealed that preview effects, which are typically summarized under preview benefit, are a complex mixture of preview cost and preview benefit and vary with preview space and preview time. The consequence for reading is that parafoveal preview may not only facilitate, but also interfere with lexical access.}, language = {en} } @inproceedings{OhlBrandtKliegl2013, author = {Ohl, Sven and Brandt, S. and Kliegl, Reinhold}, title = {Immediate preparatory influences on microsaccades before saccade onset to endogenously vs. exogenously defined targets}, series = {Perception}, volume = {42}, booktitle = {Perception}, number = {4}, publisher = {Sage Publ.}, address = {London}, issn = {0301-0066}, pages = {37 -- 38}, year = {2013}, language = {en} } @article{BlomeyerFriemelBuchmannetal.2013, author = {Blomeyer, Dorothea and Friemel, Chris M. and Buchmann, Arlette F. and Banaschewski, Tobias and Laucht, Manfred and Schneider, Miriam}, title = {Impact of pubertal stage at first drink on adult drinking behavior}, series = {Alcoholism : clinical and experimental research ; the official journal of the American Medical Society on Alcoholism and the Research Society on Alcoholism}, volume = {37}, journal = {Alcoholism : clinical and experimental research ; the official journal of the American Medical Society on Alcoholism and the Research Society on Alcoholism}, number = {10}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {0145-6008}, doi = {10.1111/acer.12154}, pages = {1804 -- 1811}, year = {2013}, abstract = {BackgroundEarly alcohol use is one of the strongest predictors of later alcohol use disorders, with early use usually taking place during puberty. Many researchers have suggested drinking during puberty as a potential biological basis of the age at first drink (AFD) effect. However, the influence of the pubertal phase at alcohol use initiation on subsequent drinking in later life has not been examined so far. MethodsPubertal stage at first drink (PSFD) was determined in N=283 young adults (131 males, 152 females) from an epidemiological cohort study. At ages 19, 22, and 23years, drinking behavior (number of drinking days, amount of alcohol consumed, hazardous drinking) was assessed using interview and questionnaire methods. Additionally, an animal study examined the effects of pubertal or adult ethanol (EtOH) exposure on voluntary EtOH consumption in later life in 20 male Wistar rats. ResultsPSFD predicted drinking behavior in humans in early adulthood, indicating that individuals who had their first drink during puberty displayed elevated drinking levels compared to those with postpubertal drinking onset. These findings were corroborated by the animal study, in which rats that received free access to alcohol during the pubertal period were found to consume more alcohol as adults, compared to the control animals that first came into contact with alcohol during adulthood.

In three tasks (touchlight, house, and obstacle), infants watched videos in which a model performed an unusual action while she was or was not restricted by situational constraints.

Overall, infants looked longer at the demonstration in the constraint condition compared with the no-constraint condition. The condition differences occurred in the two video segments where the constraint or action was displayed and were especially profound for the constraint AOI. These findings indicate that infants processed the situational constraints. However, the pattern of condition differences varied slightly in the three tasks.

Study 5 showed that the new instrument explained variance in the validation constructs beyond earlier measures of gender identity. Key message: Even in the construction of negative aspects of gender identity, individuals prefer gender-congruent attributes. Negative masculinity and femininity make a unique contribution to understanding gender-related differences in psychological outcome variables.}, language = {en} } @unpublished{Warschburger2013, author = {Warschburger, Petra}, title = {Nutrition in children and adolescents}, series = {Zeitschrift f{\"u}r Gesundheitspsychologie}, volume = {21}, journal = {Zeitschrift f{\"u}r Gesundheitspsychologie}, number = {2}, publisher = {Hogrefe}, address = {G{\"o}ttingen}, issn = {0943-8149}, pages = {49 -- 52}, year = {2013}, language = {de} } @article{FuestoesGramannHerbertetal.2013, author = {F{\"u}st{\"o}s, J{\"u}rgen and Gramann, Klaus and Herbert, Beate M. and Pollatos, Olga}, title = {On the embodiment of emotion regulation - interoceptive awareness facilitates reappraisal}, series = {Frontiers in human neuroscience}, volume = {8}, journal = {Frontiers in human neuroscience}, number = {8}, publisher = {Oxford Univ.

This study investigated the neural dynamics of reappraisal of emotional responses in 28 participants who differed with respect to IA. Electroencephalography was used to characterize the time course of emotion regulation. We found that reappraisal was accompanied by reduced arousal and significant modulation of late neural responses. What is more, higher IA facilitated downregulation of affect and was associated with more pronounced modulation of underlying neural activity. Therefore, we conclude that IA not only advances the consolidation of somatic markers required for guiding individual behaviour but also creates processing advantages in tasks referring to these bodily markers.}, language = {en} } @unpublished{KucianPlanggerO'Gormanetal.2013, author = {Kucian, Karin and Plangger, Fabienne and O'Gorman, Ruth and von Aster, Michael G.}, title = {Operational momentum effect in children with and without developmental dyscalculia}, series = {Frontiers in psychology}, volume = {4}, journal = {Frontiers in psychology}, number = {45}, publisher = {Frontiers Research Foundation}, address = {Lausanne}, issn = {1664-1078}, doi = {10.3389/fpsyg.2013.00847}, pages = {3}, year = {2013}, language = {en} } @article{MariniSriramSchnabeletal.2013, author = {Marini, Maddalena and Sriram, Natarajan and Schnabel, Konrad and Maliszewski, Norbert and Devos, Thierry and Ekehammar, Bo and Wiers, Reinout and Cai HuaJian, and Somogyi, Monika and Shiomura, Kimihiro and Schnall, Simone and Neto, Felix and Bar-Anan, Yoav and Vianello, Michelangelo and Ayala, Alfonso and Dorantes, Gabriel and Park, Jaihyun and Kesebir, Selin and Pereira, Antonio and Tulbure, Bogdan and Ortner, Tuulia and Stepanikova, Irena and Greenwald, Anthony G. and Nosekl, Brian A.}, title = {Overweight people have low levels of implicit weight bias, but overweight nations have high levels of implicit weight bias}, series = {PLoS one}, volume = {8}, journal = {PLoS one}, number = {12}, publisher = {PLoS}, address = {San Fransisco}, issn = {1932-6203}, doi = {10.1371/journal.pone.0083543}, pages = {9}, year = {2013}, abstract = {Although a greater degree of personal obesity is associated with weaker negativity toward overweight people on both explicit (i.e., self-report) and implicit (i.e., indirect behavioral) measures, overweight people still prefer thin people on average.

The national estimates of explicit and implicit weight bias were obtained by averaging the individual scores for each nation. Obesity at the individual level was defined as Body Mass Index (BMI) scores, whereas obesity at the national level was defined as three national weight indicators (national BMI, national percentage of overweight and underweight people) obtained from publicly available databases. Across individuals, greater degree of obesity was associated with weaker implicit negativity toward overweight people compared to thin people. Across nations, in contrast, a greater degree of national obesity was associated with stronger implicit negativity toward overweight people compared to thin people.

Participants (3- to 5-year-olds) watched an adult performing an unusual action in three imitation tasks (touch light, house, and obstacle).

Results revealed differences in preschoolers' selective imitation across the tasks. In the house task, they showed the selective imitation pattern that has been interpreted as rational, imitating the unusual action more often in the no-constraint condition than in the constraint condition. In contrast, in the touch light task, preschoolers imitated the unusual head touch irrespective of the model's constraints or of the verbal cues that had been presented. Finally, in the obstacle task, children mostly emulated the observed goal irrespective of the presence of the constraint, but they increased their imitation of the unusual action when the movement had been emphasized.

In Experiments 1 and 2, participants heard a low-pass filtered auditory version of the sentence, which provided a prosodic boundary cue prior to each sentence. In Experiment 1, we found that the boundary cue helped syntactic disambiguation after the cue and led to longer fixation durations on regions right before the cue than on identical regions without prosodic boundary information. In Experiments 2 and 3, we used a gaze-contingent display-change paradigm to manipulate the parafoveal visibility of the first constituent character of the target word after the disambiguating position. Results of Experiment 2 showed that previewing the first character significantly reduced the reading time of the target word, but this preview benefit was greatly reduced when the prosodic boundary cue was introduced at this position. In Experiment 3, instead of the acoustic cues, a visually presented comma was inserted at the disambiguating position in each sentence. Results showed that the comma effect on lexical processing was essentially the same as the effect of prosodic boundary cue.

Allerdings gibt es bislang nur wenig ausgearbeitete Konzepte zu den rehabilitationsmedizinischen Aufgaben niedergelassener {\"A}rzte und den ihnen zur Verf{\"u}gung stehenden diesbez{\"u}glichen Behandlungsoptionen. Methoden: Zur Kl{\"a}rung der Frage, welche Rolle rehamedizinische Aspekte in der Hausarztpraxis haben, wurden im ersten Schritt 40 niedergelassene {\"A}rzte zum gesch{\"a}tzten Anteil chronisch psychisch kranker Patienten in ihrer Praxis befragt. Im zweiten Schritt wurden 1 451 Patienten im Alter von 18 bis 60 Jahren mittels des WHO-5-Screenings zum psychischen Wohlbefinden, dem IMET-Fragebogen zu Teilhabest{\"o}rungen, der Burvillskala zur Multimorbidit{\"a}t und Fragen zum psychischen Erkrankungsstatus und Arbeitsstatus untersucht. Ergebnisse:Im Durchschnitt sch{\"a}tzten die Haus{\"a}rzte den Anteil ihrer Patienten mit psychischen Erkrankungen auf 41,9\% (SD=18,2; Range 15-90\%).Von den Patienten gaben 46,5\% an, unter psychischen Beschwerden zu leiden. 38,3\% der Patienten sagten, dass die Probleme bereits seit 6 Monaten oder l{\"a}nger bestehen (chronisch), und 26,9\% erkl{\"a}rten, dass sie die Beschwerden in den letzten 6 Monaten durchg{\"a}ngig erlebt haben (persistierend).

Accumulated evidence demonstrates that secondary saccades are subject to various influences, among which retinal feedback during postsaccadic fixation constitutes only one important signal. Recently, we reported that target eccentricity and an orientation bias influence the generation of secondary saccades. In the present study, we examine secondary saccades in the absence of postsaccadic visual feedback. Although extraretinal signals (e.g., efference copy) have received widespread attention in eye-movement studies, it is still unclear whether an extraretinal error signal contributes to the programming of secondary saccades. We have observed that secondary saccade latency and amplitude depend on primary saccade error despite the absence of postsaccadic visual feedback. Strong evidence for an extraretinal error signal influencing secondary saccade programming is given by the observation that secondary saccades are more likely to be oriented in a direction opposite to the primary saccade as primary saccade error shifts from target undershoot to overshoot. We further show how the functional relationship between primary saccade landing position and secondary saccade characteristics varies as a function of target eccentricity. We propose that initial target eccentricity and an extraretinal error signal codetermine the postsaccadic activity distribution in the saccadic motor map when no visual feedback is available.}, language = {en} } @article{SchaffnerSchiefeleSchmidt2013, author = {Schaffner, Ellen and Schiefele, Ulrich and Schmidt, Meike}, title = {The importance of family background for reading motivation and reading frequency of high school students}, series = {Zeitschrift f{\"u}r Entwicklungspsychologie und p{\"a}dagogische Psychologie}, volume = {45}, journal = {Zeitschrift f{\"u}r Entwicklungspsychologie und p{\"a}dagogische Psychologie}, number = {3}, publisher = {Hogrefe}, address = {G{\"o}ttingen}, issn = {0049-8637}, doi = {10.1026/0049-8637/a000085}, pages = {131 -- 141}, year = {2013}, abstract = {This article examines the relationships between family background and reading motivation (RM) as well as reading frequency in a sample of 156 high school students.

In these analyses, students' perceptions of reading incentives provided by the school and peer group were taken into account as control variables.

The prevalence of job-anxiety within a working population is not known. Identifying individuals who would benefit from intervention might be useful. Aims To investigate job-anxiety in employees not undergoing treatment for mental health illness, firstly by assessing the level of job-anxiety and work-related avoidance tendencies in a working sample, and secondly by testing whether job-anxiety is distinguishable from trait-anxiety. Methods Cross-sectional survey of a convenience sample obtained through personal contact distribution. Employees from different professional settings completed an anonymous questionnaire and provided information on their employment status. The State-Trait-Anxiety Inventory (STAI-T) was used to measure trait-anxiety and the Job-Anxiety-Scale (JAS) was used to assess job (state) anxiety. Results There was a 69\% response rate (240 responses); 188 responses were available for analysis of whom 62\% were women. There were no employees with high trait-anxiety. Ten employees (5\%) reported increased job-anxiety and of these nine employees reported high 'tendencies of avoidance and workplace absence'. Avoidance was most often accompanied by the comorbid job-anxieties 'job-related social anxiety', 'fear of changes at work' and 'fears of existence', 'anticipatory' and 'conditioned' job-anxiety and 'panic symptoms'. Conclusions In this sample, self-reported job-anxiety appeared as a specific type of anxiety as opposed to trait-anxiety. In the workplace job-anxiety can present as job-avoidance and sickness absence and should be distinguished from trait-anxiety. In practice, employers and occupational health practitioners should be aware of those employees prone to sickness absence.}, language = {en} } @book{Krahe2013, author = {Krah{\´e}, Barbara}, title = {The social psychology of aggression}, edition = {2nd ed.}, publisher = {Psychology Press}, address = {New York}, isbn = {978-1-84169-874-8}, pages = {XIV, 398 S.}, year = {2013}, language = {en} } @unpublished{CaligioreFischer2013, author = {Caligiore, Daniele and Fischer, Martin H.}, title = {Vision, action and language unified through embodiment}, series = {Psychological research : an international journal of perception, attention, memory, and action}, volume = {77}, journal = {Psychological research : an international journal of perception, attention, memory, and action}, number = {1}, publisher = {Springer}, address = {Heidelberg}, issn = {0340-0727}, doi = {10.1007/s00426-012-0417-0}, pages = {1 -- 6}, year = {2013}, language = {en} } @article{RolfsDambacherCavanagh2013, author = {Rolfs, Martin and Dambacher, Michael and Cavanagh, Patrick}, title = {Visual adaptation of the perception of causality}, series = {Current biology}, volume = {23}, journal = {Current biology}, number = {3}, publisher = {Cell Press}, address = {Cambridge}, issn = {0960-9822}, doi = {10.1016/j.cub.2012.12.017}, pages = {250 -- 254}, year = {2013}, abstract = {We easily recover the causal properties of visual events, enabling us to understand and predict changes in the physical world. We see a tennis racket hitting a ball and sense that it caused the ball to fly over the net; we may also have an eerie but equally compelling experience of causality if the streetlights turn on just as we slam our car's door. Both perceptual [1] and cognitive [2] processes have been proposed to explain these spontaneous inferences, but without decisive evidence one way or the other, the question remains wide open [3-8]. Here, we address this long-standing debate using visual adaptation-a powerful tool to uncover neural populations that specialize in the analysis of specific visual features [9-12]. After prolonged viewing of causal collision events called "launches" [1], subsequently viewed events were judged more often as noncausal. These negative aftereffects of exposure to collisions are spatially localized in retinotopic coordinates, the reference frame shared by the retina and visual cortex. They are not explained by adaptation to other stimulus features and reveal visual routines in retinotopic cortex that detect and adapt to cause and effect in simple collision stimuli.}, language = {en} } @article{MyachykovEllisCangelosietal.2013, author = {Myachykov, Andriy and Ellis, Rob and Cangelosi, Angelo and Fischer, Martin H.}, title = {Visual and linguistic cues to graspable objects}, series = {Experimental brain research}, volume = {229}, journal = {Experimental brain research}, number = {4}, publisher = {Springer}, address = {New York}, issn = {0014-4819}, doi = {10.1007/s00221-013-3616-z}, pages = {545 -- 559}, year = {2013}, abstract = {Two experiments investigated (1) how activation of manual affordances is triggered by visual and linguistic cues to manipulable objects and (2) whether graspable object parts play a special role in this process. Participants pressed a key to categorize manipulable target objects copresented with manipulable distractor objects on a computer screen. Three factors were varied in Experiment 1: (1) the target's and (2) the distractor's handles' orientation congruency with the lateral manual response and (3) the Visual Focus on one of the objects. In Experiment 2, a linguistic cue factor was added to these three factors-participants heard the name of one of the two objects prior to the target display onset. Analysis of participants' motor and oculomotor behaviour confirmed that perceptual and linguistic cues potentiated activation of grasp affordances. Both target- and distractor-related affordance effects were modulated by the presence of visual and linguistic cues. However, a differential visual attention mechanism subserved activation of compatibility effects associated with target and distractor objects. We also registered an independent implicit attention attraction effect from objects' handles, suggesting that graspable parts automatically attract attention during object viewing. This effect was further amplified by visual but not linguistic cues, thus providing initial evidence for a recent hypothesis about differential roles of visual and linguistic information in potentiating stable and variable affordances (Borghi in Language and action in cognitive neuroscience.

Based on Ackerman's (1996) notion of trait complexes, specific interest profiles of gifted high-school graduates can be expected. Aims.Vocational interests of gifted and highly achieving adolescents were compared to those of their less intelligent/achieving peers according to Holland's (1997) RIASEC model. Further, the impact of intelligence and achievement on interests were analysed while statistically controlling for potentially influencing variables. Changes in interests over time were investigated. Sample.N= 4,694 German students (age: M= 19.5, SD= .80; 54.6\% females) participated in the study (TOSCA; Koller, Watermann, Trautwein, \& Ludtke, 2004). Method. Interests were assessed in participants' final year at school and again 2 years later (N= 2,318). Results.Gifted participants reported stronger investigative and realistic interests, but lower social interests than less intelligent participants. Highly achieving participants reported higher investigative and (in wave 2) higher artistic interests. Considerable gender differences were found: gifted girls had a flat interest profile, while gifted boys had pronounced realistic and investigative and low social interests. Multilevel multiple regression analyses predicting interests by intelligence and school achievement revealed stable interest profiles. Beyond a strong gender effect, intelligence and school achievement each contributed substantially to the prediction of vocational interests. Conclusions.At the time around graduation from high school, gifted young adults show stable interest profiles, which strongly differ between gender and intelligence groups. These differences are relevant for programmes for the gifted and for vocational counselling.}, language = {en} } @article{KroellerKroellerWarschburger2013, author = {Kr{\"o}ller, Katja and Kr{\"o}ller, Alexander and Warschburger, Petra}, title = {What do you like to eat?

There are many factors which affect the development of food preferences. The familiarity with different foods seems to be a special aspect associated with the corresponding preference. To establish a preference for fruits and vegetables during early childhood, we need to know more about the factors that affect this preference development. So far, research has mostly concentrated on the food intake and less on the corresponding preference. Additionally, it is often based on studies of the mere-exposure effect or on older children and their ability to label fruits and vegetables correctly. Findings about the level of food familiarity in young children and its relation to the actual food preference are still missing. Our study focuses on different aspects of food familiarity as well as on their relationship to the child's preference and presents results from 213 children aged 2 to 10 years. Using standardized photos, the food preference was measured with a computer-based method that ran automatically without influence from parents or interviewer. The children knew fewer of the presented vegetables (66 \%) than fruits or sweets (78 \% each). About the same number of vegetables (63 \%) had already been tasted by the children and were considered tasty. Only 48 \% of the presented vegetables were named correctly - an ability that increases in older children. Concerning the relationship between the familiarity with vegetables and their preference, the different familiarity aspects showed that vegetables of lower preference were less often recognized, tasted, considered tasty, or named correctly.}, language = {de} } @article{RodriguezVillagraGoetheOberaueretal.2013, author = {Rodriguez-Villagra, Odir Antonio and G{\"o}the, Katrin and Oberauer, Klaus and Kliegl, Reinhold}, title = {Working memory capacity in a go/no-go task - age differences in interference, processing speed, and attentional control}, series = {Developmental psychology}, volume = {49}, journal = {Developmental psychology}, number = {9}, publisher = {American Psychological Association}, address = {Washington}, issn = {0012-1649}, doi = {10.1037/a0030883}, pages = {1683 -- 1696}, year = {2013}, abstract = {We tested the limits of working-memory capacity (WMC) of young adults, old adults, and children with a memory-updating task.

The interference model (IM) of Oberauer and Kliegl (2006) was simultaneously fitted to the data of all groups.

In this study, we examined the IM parameters across the life span. The IM parameter estimates show that (a) conditions were not different in interference by feature overlap and interference by confusion; (b) switching costs time; (c) young adults and children were less susceptible than old adults to interference due to feature overlap; (d) noise was highest for children, followed by old and young adults; (e) old adults differed from children and young adults in lower processing rate; and (f) children and old adults had a larger switch cost between go steps and no-go steps.
