Assessment of psychopathology in 2‐ to 5‐year‐olds: Applying the Infant–Toddler Social Emotional Assessment

The information provided by parents is indispensable for the early identification of psychopathology; for this reason, developmentally appropriate, reliable, and valid questionnaires are needed to gather their information. This study was designed to examine the utility of the Infant Toddler Social Emotional Assessment (ITSEA), a parent‐report questionnaire covering a wide range of behavior and emotional problems and competencies, in preschoolers referred for child psychiatric evaluation. The fathers and mothers of 85 children (23.2% girls; age 15–57 months) with autism spectrum, externalizing, or internalizing disorders completed the ITSEA, the Child Behavior Checklist (CBCL/2–3 and 4–18 versions), and the child domain of the Parenting Stress Index (PSI). The ITSEA showed good interrater reliability between parents, and validity was supported by significant correlations with corresponding CBCl and PSI domains. Evidence supporting the validity of the ITSEA for psychopathology was mixed across scales, with good diagnostic accuracy at the level of the broader psychiatric syndromes being achieved by the combination of subscales within the Externalizing, Internalizing, and Competence domains. The value of the ITSEA lies in the ability to systematically evaluate a wide range of problem behaviors and competencies. The ITSEA may be useful to create profiles of children's functioning in preschoolers referred for psychiatric assessment.     

Brain dynamics of word familiarization in 20-month-olds: effects of productive vocabulary size

The present study investigated the brain mechanisms involved during young children's receptive familiarization with new words, and whether the dynamics of these mechanisms are related to the child's productive vocabulary size. To this end, we recorded event-related potentials (ERPs) from 20-month-old children in a pseudoword repetition task. Results revealed distinct patterns of repetition effects for children with large and small productive vocabularies. High producers showed evidence of recognizing the novel words already after three presentations, while the low producers needed five presentations to display a recognition effect. The familiarization process was manifested in the modulations of two components, the N200-400 and a later fronto-central component, which appeared to increase in amplitude until a certain level of encoding was reached and then decrease with further repetition. These findings suggest a relation between the onset of the productive vocabulary spurt and the rate of receptive word familiarization.     

Environment and Physical Activity Dynamics: The Role of Residential Self-selection

OBJECTIVES: Within the socio-ecologic framework, diet and physical activity are influenced by individual, interpersonal, organizational, community, and public policy factors. A basic principle underlying this framework is that environments can influence an individual's behavior. However, in the vast majority of cross-sectional and even the few longitudinal studies of this relationship, the question of whether individuals select their area of residence based on physical activity-related amenities is ignored. In this paper, we address a critical methodological issue: self-selection of residential location, which is generally not accounted for, and can significantly compromise research on the relationship between environmental factors and physical activity behaviors. METHOD: We define and discuss the problem of residential self-selection in the study of neighborhood influences on health and health behavior, review methods used to control for residential self-selection in the literature, and present our strategy for addressing this potentially important source of bias. CONCLUSION: Existing research has built our understanding of residential self-selection bias, but important gaps remain. Our strategy uses data from a longitudinal cohort study linked to contemporaneous environmental measures to create a multi-equation model system to simultaneously estimate residential choice, environmental influences on physical activity, and downstream health outcomes such as obesity and clinical cardiovascular disease risk factor measures.     

Displayed emotions and witness credibility: a comparison of judgements by individuals and mock juries

Mock juries of 5–7 jurors viewed one of three video‐recorded versions of a rape victim's testimony, role‐played by a professional actress. The statement was given in a free‐recall manner with one of three kinds of emotions displayed, termed congruent, neutral and incongruent emotional expressions. The juries were requested to reach a decision on items in a short questionnaire, probing the perceived credibility of the witness and judgements of the probability of a guilty verdict. The jurors were then asked to complete the questionnaire a second time, individually and anonymously. A control group filled out the questionnaire individually without preceding jury deliberations. When participants judged credibility and guilt independently, without a preceding jury discussion, the displayed emotions strongly influenced the judgements. However, discussions in the context of the jury strongly attenuated the effect of displayed emotion, with judgements converging on the credibility of a neutral emotional expression as judged by independent participants, and the attenuating effect outlasted the jury‐situation. The results are consistent with research within social psychology showing that social stereotypes and prejudices are often neutralised by group discussions.

Attention‐shift vs. response‐priming explanations for the spatial cueing effect in cross‐modal tasks

The task‐irrelevant spatial location of a cue stimulus affects the processing of a subsequent target. This “Posner effect” has been explained by an exogenous attention shift to the spatial location of the cue, improving perceptual processing of the target. We studied whether the left/right location of task‐irrelevant and uninformative tones produces cueing effects on the processing of visual targets. Tones were presented randomly from left or right. In the first condition, the subsequent visual target, requiring response either with the left or right hand, was presented peripherally to left or right. In the second condition, the target was a centrally presented left/right‐pointing arrow, indicating the response hand. In the third condition, the tone and the central arrow were presented simultaneously. Data were recorded on compatible (the tone location and the response hand were the same) and incompatible trials. Reaction times were longer on incompatible than on compatible trials. The results of the second and third conditions are difficult to explain with the attention‐shift model emphasizing improved perceptual processing in the cued location, as the central target did not require any location‐based processing. Consequently, as an alternative explanation they suggest response priming in the hand corresponding to the spatial location of the tone. Simultaneous lateralized readiness potential (LRP) recordings were consistent with the behavioral data, the tone cues eliciting on incompatible trials a fast preparation for the incorrect response and on compatible trials preparation for the correct response.     

How does it feel to become a teacher? Emotions in teacher education

Academic emotions are central ingredients in student teachers’ learning. They have been shown to affect cognitive performance, motivation and achievement (e.g. Linnenbrink-Garcia et al. in Contemp Educ Psychol 36(1):13–24, 2011). However, until recently the role of emotions in student teachers’ learning has largely been neglected (e.g. Ketonen and Lonka in Proc Soc Behav Sci 69(24):1901–1910, 2012). The study focused on exploring the spectrum of academic emotions experienced by 19 student teachers in different academic activities. The results showed that student teachers experience a wide variety of emotions during their studies. A total of 18 different positive emotions and 20 different negative emotions were reported. They explicated more positive than negative emotions. Further investigations showed that student teachers reported more emotional experiences embedded in individual activities than in social activities. The results implied that the spectrum of academic emotions experienced by student teachers is wider than previous literature suggests, and that student teachers experience a wide range of academic emotions in various academic activities provided by teacher education.

Selectivity in probabilistic causality: Where psychology runs into quantum physics

Given a set of several inputs into a system (e.g., independent variables characterizing stimuli) and a set of several stochastically non-independent outputs (e.g., random variables describing different aspects of responses), how can one determine, for each of the outputs, which of the inputs it is influenced by? The problem has applications ranging from modeling pairwise comparisons to reconstructing mental processing architectures to conjoint testing. A necessary and sufficient condition for a given pattern of selective influences is provided by the Joint Distribution Criterion, according to which the problem of “what influences what” is equivalent to that of the existence of a joint distribution for a certain set of random variables. For inputs and outputs with finite sets of values this criterion translates into a test of consistency of a certain system of linear equations and inequalities (Linear Feasibility Test) which can be performed by means of linear programming. While new in the behavioral context, both this test and the Joint Distribution Criterion on which it is based have been previously proposed in quantum physics, in dealing with generalizations of Bell inequalities for the quantum entanglement problem. The parallels between this problem and that of selective influences in behavioral sciences are established by observing that noncommuting measurements in quantum physics are mutually exclusive and can therefore be treated as different levels of one and the same factor.
