BINGE DRINKING AMONG AMERICAN COLLEGE WOMEN

This study examines data from questionnaires to establish the prevalence and correlates of women's binge drinking, defined as four or more drinks per episode, at women's colleges ( n = 508) and at coeducational colleges ( n = 9,624). Results showed that women at women's colleges binged less frequently, had fewer alcohol-related problems, experienced fewer negative effects of others' drinking, and were less likely to drink and drive. The correlates of binge drinking were similar for the two groups of women. The differences appear to be related not to the quantity or amount of socializing but to its quality. The absence of fraternities and coeducational dormitories, the reduced likelihood of a party-centered lifestyle, and self-selection factors at women's colleges all may contribute to a healthier environment for women. Interventions designed to lower the risk of college binge drinking should further explore the peer-group contexts in which problem drinking is reduced.     

A Meta-Analysis of the Association Between Birth Weight and Attention Deficit Hyperactivity Disorder

A large body of work has investigated the association between birth weight and ADHD and has resulted in mixed findings with regard to the direction and magnitude of this association. Despite the vast amount of research on this topic, a comprehensive and systematic quantification of the association between birth weight and ADHD has yet to be undertaken. A meta-analysis of 88 unique studies (N?=?4,645,482) was conducted to quantify the overall effect size of birth weight on ADHD symptoms. Several variables were examined as moderators that may contribute to systematic variation in effect sizes. Overall, birth weight was found to have a small, but significant, association with ADHD symptoms such that individuals born at lower birth weights manifested greater symptoms of ADHD (r?=??0.15). Sample type, mean birth weight of the sample, geographic region, the informant of ADHD symptoms, ADHD symptom measurement method, and race were all found to contribute significantly to heterogeneity in effect sizes. Notably, several early life risk factors previously found to be associated with both ADHD and birth weight, gestational age and prenatal smoking exposure, were not found to contribute to heterogeneity in effect sizes. The findings of the current analyses align with the growing recognition that early life adversity contributes to neurodevelopmental difficulties, and the findings highlight the importance of a better understanding of the mechanisms underlying the association between early life risk factors and adverse neurodevelopmental sequela, such as that observed in ADHD.     

Semantic richness and word learning in children with autism spectrum disorder

Semantically rich learning contexts facilitate semantic, phonological, and articulatory aspects of word learning in children with typical development (TD). However, because children with autism spectrum disorder (ASD) show differences at each of these processing levels, it is unclear whether they will benefit from semantic cues in the same manner as their typical peers. The goal of this study was to track how the inclusion of rich, sparse, or no semantic cues influences semantic, phonological, and articulatory aspects of word learning in children with ASD and TD over time. Twenty‐four school‐aged children (12 in each group), matched on expressive vocabulary, participated in an extended word learning paradigm. Performance on five measures of learning (referent identification, confrontation naming, defining, phonetic accuracy, and speech motor stability) were tracked across three sessions approximately one week apart to assess the influence of semantic richness on extended learning. Results indicate that children with ASD benefit from semantically rich learning contexts similarly to their peers with TD; however, one key difference between the two groups emerged – the children with ASD showed heightened shifts in speech motor stability. These findings offer insights into common learning mechanisms in children with ASD and TD, as well as pointing to a potentially distinct speech motor learning trajectory in children with ASD, providing a window into the emergence of stereotypic vocalizations in these children.     

Understanding supplement use: an application of temporal self-regulation theory

Vitamin and mineral supplement use is increasing worldwide. As evidence of the effects of these practices are equivocal at best, it is important to determine why individuals engage in vitamin and mineral supplement use through the application of a theoretical framework. The aim of this study was to employ temporal self-regulation theory (TST) to establish the determinants of supplement use. A cross-sectional design was used with a sample of 121 individuals who consume vitamins or minerals as dietary supplements. Hierarchical regression analyses were conducted to determine the influence of intention, habit, self-control, and the interaction between intention and habit and self-control on the frequency of supplement use. The model accounted for a significant proportion of variance in behaviour (R² = .44) with intention and habit significantly related to supplement use. Self-control moderated the relationship between intention and behaviour indicating that intention was not related to behaviour when self-control was low. The TST model offers a satisfactory account of supplement use and provides avenues for interventions aimed at increasing safe and beneficial supplement use and decreasing potentially harmful supplement use.     

Some supplementary methods for the analysis of the Delis-Kaplan Executive Function System

Supplementary methods for the analysis of the Delis-Kaplan Executive Function System (Delis, Kaplan, & Kramer, 2001) are made available, including (a) quantifying the number of abnormally low achievement scores exhibited by an individual and accompanying this with an estimate of the percentage of the normative population expected to exhibit at least this number of low scores; (b) estimating the overall abnormality of an individual's achievement score profile with the Mahalanobis distance index; (c) calculating a composite executive function index score for an individual and providing accompanying confidence limits; and (d) providing the percentile ranks for an individual's achievement scores and executive index score (in the latter case, confidence limits on scores are also expressed as percentile ranks). With the exception of the Mahalanobis distance index, all the methods can be obtained with the equations and tables provided in this article. However, for the convenience of clinicians and to reduce the possibility of clerical error, the methods have also been implemented in a computer program. More important, the program allows the methods to be applied when only a subset of scores is available. The program can be downloaded (as a zip file) from this article's supplemental materials or from www.abdn.ac.uk/~psy086/dept/DKEFS_Supplementary_Analysis.htm.     

Personal and Professional Development for Judges: The Institute for Faculty Excellence

This interview study describes the role that participation in the Institute for Faculty Excellence in Judicial Education (IFEJE) played in the personal and professional development of four judges. Judicial education is a relatively new field of adult and continuing professional education. There is limited literature devoted to this area of study outside of the arena of substantive legal or judging topics. Interviews served as the primary data source for this study along with program evaluations, photographs, and e-mail correspondence from Institute participants. The findings revealed that the combined safe environment, challenges, and support participants experienced at the Institute and learning about adult learning helped them: feel less isolated in their work; stretch their normal work boundaries resulting in the completion of projects for which they had great passion; and benefited them as judges, supervisors, teachers, and in other social relationships.     

Person perception informs understanding of cognition during visual search

Does person perception—the impressions we form from watching others—hold clues to the mental states of people engaged in cognitive tasks? We investigated this with a two-phase method: In Phase 1, participants searched on a computer screen (Experiment 1) or in an office (Experiment 2); in Phase 2, other participants rated the searchers’ video-recorded behavior. The results showed that blind raters are sensitive to individual differences in search proficiency and search strategy, as well as to environmental factors affecting search difficulty. Also, different behaviors were linked to search success in each setting: Eye movement frequency predicted successful search on a computer screen; head movement frequency predicted search success in an office. In both settings, an active search strategy and positive emotional expressions were linked to search success. These data indicate that person perception informs cognition beyond the scope of performance measures, offering the potential for new measurements of cognition that are both rich and unobtrusive.
