Time-Out for Sibling Aggression: An Analysis of Effective Durations in a Natural Setting

Abstract

Time-out is a ubiquitous strategy to reduce problem behaviors. The current study sought to find the shortest effective duration(s) of time-out for sibling aggression in a community sample of girls ages 3–7. All participants reached a minimum reduction in sibling aggression of 60% after experiencing a 1-minute time-out. The majority (75%) of participants also demonstrated clear reversals of behavior when returned to the baseline condition. The current findings suggest that a 1-minute time-out may be sufficient for low-level sibling aggression in children as old as seven. Limitations include the presence of a graduate assistant during sibling play and unclear generalizability.     

Rejoinder to commentators on structural equations modeling primers: Bentler,Bagozzi, and Fabrigar,Porter, and Norris

In this brief article, I applaud the commentators for the many points they make, their offering additional perspectives, and for expanding the territory of structural equations modeling coverage begun in the Journal of Consumer Psychology primers.     

Structural equations modeling: Fit Indices,sample size,and advanced topics

This article is the second of two parts intended to serve as a primer for structural equations models for the behavioral researcher. The first article introduced the basics: the measurement model, the structural model, and the combined, full structural equations model. In this second article, advanced issues are addressed, including fit indices and sample size, moderators, longitudinal data, mediation, and so forth.     

‘It's not that we hate you’: Understanding children's gender attitudes and expectancies about peer relationships

Widespread gender segregation, evident throughout elementary school, seems to imply that girls and boys have negative feelings and thoughts about one another, and classic theories of inter‐group processes support this idea. However, research has generally overlooked children's feelings and perceptions about gender‐related interpersonal interactions. This paper investigates the nature of children's attitudes about same‐ and other‐gender peers, and explores how those attitudes relate to the expectancies and beliefs children hold about same‐ and other‐gender peer interactions. Children (N= 98 fifth graders) completed questionnaires assessing their global liking of own‐ and other‐gender peers ( Yee & Brown, 1994 ), positive and negative attitudes about own‐ and other‐gender peers, and outcome expectancies related to interacting with own‐ and other‐gender peers. Results indicated that rather than being characterized by out‐group negativity, children's inter‐group gender attitudes are best characterized by an in‐group positivity bias. Children's positive and negative affective attitudes were also significantly associated with outcome expectancies. In contrast, global liking of own‐ and other‐gender peers was less predictive of outcome expectancies. Thus, the greater specificity of the affective attitude measures appeared to be a more predictive and potentially fruitful gauge of children's feelings about own‐ and other‐gender peers. Results are discussed in terms of the need for finer grained and more extensive studies of children's gender‐related feelings and cognitions about own‐ and other‐gender peers.     

A comparison of conscious and automatic memory processes for picture and word stimuli: a process dissociation analysis

Four experiments were conducted to evaluate explanations of picture superiority effects previously found for several tasks. In a process dissociation procedure (Jacoby, 1991) with word stem completion, picture fragment completion, and category production tasks, conscious and automatic memory processes were compared for studied pictures and words with an independent retrieval model and a generate-source model. The predictions of a transfer appropriate processing account of picture superiority were tested and validated in "process pure" latent measures of conscious and unconscious, or automatic and source, memory processes. Results from both model fits verified that pictures had a conceptual (conscious/source) processing advantage over words for all tasks. The effects of perceptual (automatic/word generation) compatibility depended on task type, with pictorial tasks favoring pictures and linguistic tasks favoring words. Results show support for an explanation of the picture superiority effect that involves an interaction of encoding and retrieval processes.     

Fabry Disease Practice Guidelines: Recommendations of the National Society of Genetic Counselors

Identification and comprehensive care of individuals who have Fabry disease (FD) requires a multidisciplinary approach inclusive of genetic testing, test interpretation, genetic counseling, long term disease symptom monitoring, treatment recommendations, and coordination of therapy. The purpose of this document is to provide health care professionals with guidelines for testing, care coordination, identification of psychosocial issues, and to facilitate a better understanding of disease treatment expert recommendations for patients with Fabry disease. These recommendations are the opinions of a multicenter working group of genetic counselors, medical geneticists, and other health professionals with expertise in Fabry disease counseling, as well as representatives/founders of the two United States based Fabry disease patient advocacy groups who are themselves affected by Fabry disease. The recommendations are U.S. Preventive Task Force Class III, and they are based on clinical experience, a review of pertinent English-language articles, and reports of expert committees. This document reviews the genetics of Fabry disease, the indications for genetic testing, interpretation of results, psychosocial considerations, and references to professional and patient resources.     

Age Comparisons in Workplace Sexual Harassment Perceptions

Few studies have systematically examined the influence of perceivers’ age on perceptions of sexual harassment. We sought to fill this gap, determine whether sexist attitudes mediate relations between age and sexual harassment perceptions, and whether relations between gender, sexist attitudes and perceptions are moderated by age. Results from an age-stratified sample of 965 students and staff employees at a US Midwestern university found a positive relationship between age and sexual harassment perceptions. Hostile sexism partially mediated this relationship, but age did not moderate correlations with gender or sexist attitudes. College-aged samples are less sensitive to harassment than older-aged samples, but the validity of other predictors of sexual harassment perceptions, such as gender and sexist attitudes, remains intact regardless of sample age.     

Working memory and sequence learning in the Hebb Digits task: awareness is predicted by individual differences in operation span

We examined the extent to which individual differences contribute to performance in a task considered to index implicit learning, the Hebb Digits task. Although Hebb Digits learning is considered to be equivalent for those with implicit and explicit knowledge of the repeating digit pattern, this study found that participants who developed explicit knowledge showed learning, whereas those without explicit knowledge did not. Additionally, participants who developed explicit knowledge outperformed participants without explicit knowledge on working memory measures, specifically the Automated Operation Span Task total correct score and absolute score. However, no significant differences were found between those who did and who did not develop explicit knowledge on the Hopkins Verbal Learning Task-Revised, which uses delayed recall to index long-term memory. These results suggest that learning and awareness in the Hebb Digits task relies on individual differences in working memory capacity.
