Objective: The authors examined perceived norms and drinking among college students who attended high schools in rural and urban communities. Participants and Methods: Undergraduates (99 men and 85 women) who attended high schools in communities with populations ranging from less than 100 to more than 400,000 completed surveys assessing perceived…

This study examined the effects of educational messages provided by a student with autism on middle school students' cognitive and conative attitudes. Students (N = 233; M age = 13.07 years) viewed a videotape of an unfamiliar student exhibiting autism-like behaviors and received one of four messages provided by the student via a written pamphlet.…

Autism spectrum disorders (ASDs) are more frequently associated with tic disorders than expected by chance. Variable rates of comorbidity have been reported and common genetic and neurobiological factors are probably involved. The aim of this study was to determine the rate of tic disorders in a clinical sample (n = 105) of children and…

Adolescence is a transitional period when the pressure to engage in romantic and sexual relationships can leave teenagers feeling confused and at risk for sexual coercion. Our studies investigated characteristics of male and female perpetrators and victims of peer sexual coercion, focusing on self-esteem, sexist attitudes, and involvement in…

This study describes the academic, social, and behavioral performance of elementary and secondary students with emotional and behavioral disorders (EBD) receiving services in a self-contained school for students with serious behavior problems, with an emphasis on how school adjustment and problem behavior patterns predict academic performance.…

Interest and inflation rates may be major determinants of delay discounting, but these variables have not been controlled in past experiments because they depend on macroeconomic conditions. This study uses a computer game-like task to investigate the effects of inflation rates on people's subjective valuation of delayed rewards. During the task,…

This research is an examination of the interactions between 19 pairs of student teachers and cooperating teachers engaged in guided reading instruction in Grades 1 through 3. As the basis for the study, the authors analyzed interaction patterns through conducting content analysis (Van Sluys, Lewison, & Seely Flint, 2006) and discourse analysis…

Gottlieb's (1991/2007) target article represents a milestone in our understanding of the impact of social experience on developmental malleability. Interactions across the species-typical and operant behavior categories are increasingly understood to exist. The social contingencies present in the normal species-typical developmental manifold are…

The role of parental communication and instruction concerning sexual behaviour were studied in a community-based sample of 1083 youth aged 13-17 (mean age of 15 years; 51% girls, 49% White). The Youth Asset Survey was administered along with items measuring demographics and youth risk behaviours. After controlling for demographic factors,…

This longitudinal study examined links between disorganization and atypical maternal behavior at 12 and 24 months in 71 adolescent mother-child dyads. Organized attachment and maternal not disrupted behavior were more stable than disorganization and disrupted behavior, respectively. At both ages, disorganization and maternal disrupted behavior…

Harassment and bullying among 186 students with intellectual disabilities, ages 12 to 21 years, in special education schools were examined. The differences between bullies and victims in terms of social adjustment and social skills were investigated. No prototypes characterizing differences in social skills were found between the three subgroups:…

Background: To assess the co-occurrence in deviant trajectories of parent-rated symptoms of conduct disorder (CD), oppositional defiant disorder (ODD) and attention-deficit/hyperactivity disorder (ADHD) from age 4 to 18 years old in a general population sample of Dutch children. Methods: Developmental trajectories of CD, ODD, and ADHD were…

This study used data from the National Institute of Child Health and Human Development's Study of Early Child Care and Youth Development to examine relations between parenting, self-control, and externalizing behavior from infancy through 5th grade. Results indicate that self-control measured during middle childhood mediates relations between…

Callous and unemotional (CU) traits have been linked to severe antisocial behavior in youth, but studies examining the etiology of CU traits are lacking. Based on prior research, it was hypothesized that childhood anxiety and parenting practices would interact to predict changes in CU traits over time. Hypotheses were tested using a sample of 120…

Background: Some young children reared in profoundly depriving institutions have been found to show autistic-like patterns, but the developmental significance of these features is unknown. Methods: A randomly selected, age-stratified, sample of 144 children who had experienced an institutional upbringing in Romania and who were adopted by UK…
