Increasing students' opportunities to respond (OTR) is a low-intensity strategy effective in increasing engagement. Building on the work of Haydon and colleagues, we compared two types of OTR, choral and mixed (70% choral, 30% individual), to examine the utility of these strategies in increasing active student responding and accuracy during…

Background: Autism spectrum disorder (ASD) is characterized by notable phenotypic heterogeneity, which is often viewed as an obstacle to the study of its etiology, diagnosis, treatment, and prognosis. On the basis of empirical evidence, instead of three binary categories, the upcoming edition of the DSM 5 will use two dimensions--social…

A substantial amount of research has suggested that adolescents' attitudes and behaviors are influenced by peers; however, little is known regarding adolescents' individual variability, or susceptibility, to peer influence. In this study, a performance-based index from an experimental paradigm was used to directly measure adolescents'…

Background: Aggression is a common type of problem behaviour in clients with mild to borderline intellectual disability who live in a residential facility.

Variations in parents' emotion socialization have been linked to children's social competence (SC) and behavior problems, but parental influences do not act independently of children's characteristics. A biopsychosocial model was tested, in which children's parasympathetic regulation of cardiac function and paternal and maternal socialization of…

Stimulus properties of toys may impact the type and amount of play observed between children with autism and their playmates. Six children with autism and their siblings participated in an evaluation of toy characteristics on type of play, problem behavior, social initiations, and responses to social initiations. Separate free operant preference…

Investigated behavioral adjustment of 61 children (ages 4-16) during terminal illness and first year following sibling's death from cancer.

This study, involving 4 children (ages 6 and 11) with autism, demonstrated that a self-management technique was effective in improving responsiveness to verbal initiations from others and in extending responsiveness to settings (community, home, and school) without the presence of a treatment provider. Concomitant reductions in disruptive behavior…

Biased social information processing has been solidly linked to aggressive behavior in children. Additionally, attributional tendencies, the tendency to overattribute deliberately hostile intentions to others, have been shown to distinguish aggressive and nonaggressive male youth. In order to reduce aggressive males' tendency to attribute hostile…
