Research on bullying and victimization largely rests on univariate analyses and on reports from a single informant. Researchers may thus know too little about the simultaneous effects of various independent and dependent variables, and their research may be biased by shared method variance. The database for this Dutch study was large (N=1,065) and…

A well-established approach to modeling clustered data introduces random effects in the model of interest. Mixed-effects logistic regression models can be used to predict discrete outcome variables when observations are correlated. An extension of the mixed-effects logistic regression model is presented in which the dependent variable is a latent…

This study examines how rapid automatized naming (RAN) components-articulation time and pause time-develop from kindergarten to the end of first grade and how RAN components are related to different reading measures and to RAN total time. Sixty-two children were administered RAN tasks in kindergarten and at the beginning and end of Grade 1.…

Although the importance of religion in the lives of older African Americans is well documented, this is the 1st study to examine the relations between religious involvement and psychological well-being among a sample comprised exclusively of older African Americans. Eighty six participants completed multidimensional measures of religious…

Two studies investigated the relationship between working memory capacity (WMC), adult age, and the resolution of conflict between familiarity and recollection in short-term recognition tasks. Experiment 1 showed a specific deficit of young adults with low WMC in rejecting intrusion probes (i.e., highly familiar probes) in a modified Sternberg…

This study compares the classification accuracy of linear discriminant analysis (LDA), quadratic discriminant analysis (QDA), logistic regression (LR), and classification and regression trees (CART) under a variety of data conditions. Past research has generally found comparable performance of LDA and LR, with relatively less research on QDA and…

In 1997, the state of South Dakota instituted an incentive program to reward institutions for performance related to state policy priorities. The program had a specified starting and ending point, running its course in 2002. This program provides a unique opportunity to study the connection between higher education policy and performance, an issue…

Infants and toddlers are more likely to be victims of neglect than any other form of maltreatment. Infants and toddlers are at highest risk of fatality because of maltreatment and experience behavioral, social, academic, medical, and cognitive consequences of neglect during their most formative years. Within an ecological framework, this study…

This article demonstrates the importance of social support from students' significant others (parents, peers and teachers) in the process of doing well at school. The main focus of the research project was to find correlations between the quality of adolescents' relationships with significant others and their school success or school failure, as…

This study explored perceived racism and the usual ways of coping with these perceptions in a sample of 269 Black university students (53% female). Perceptions of inter- and intragroup racism were assessed with the Life Experiences and Stress scale, and coping was measured with the Coping Orientations to Problems Experienced scale. A principal…

Given the explosion in growth of out-of-the-home child care, increasing attention is being focused on the developmental consequences of early childhood environments. The authors show that the ratio of children to the number of activity areas in the classroom is positively correlated with off-task time. There is also a marginal, negative…

This study focused on two conceptually distinct measures of the filial responsibility expectations of older adults: a vignette technique and an attitude item scale. Data were based on 1,553 respondents aged 61 to 92 years who participated in the Longitudinal Aging Study Amsterdam in 1998 to 1999.The results showed that the item scale had multiple…

Concurrent and predictive relationships between peer harassment and problem behavior were examined for middle and high school students as well as gender differences in these relationships. Students recruited in fifth through seventh grades (n = 223) and their parents provided quarterly questionnaire data and were followed up into high school. As…

Two types of behaviours shown in children--those reflecting social impairment and nonsocial obsessive repetitive behaviours--are central to defining and diagnosing autism spectrum disorders (ASDs). Parent and teacher data on social and nonsocial behaviours were obtained from a community sample of greater than 3000 7-year-old twin pairs. Social and…

The phenomenon of childhood bullying is conceptualized from an evolutionary psychological perspective. In this manuscript, the research literature is examined regarding the role of the relationship between aggression, testosterone, and social status in the development and maintenance of dominance hierarchies, which involve a reciprocal…
