Background: Both transactional and common etiological models have been proposed as explanations of why externalizing behavior problems (EBP) and internalizing behavior problems (IBP) co-occur in children. Yet little research has empirically evaluated these competing theoretical explanations. We examined whether EBP and IBP are transactionally…

Despite widespread enthusiasm for remedial education programming with refugee populations, there is little rigorous evidence on how to design and implement such programs. We employ a cluster-randomized design of non-equivalent treatment groups to test the impact of access to two types of program enhancement: longer program duration and the…

Over the past several decades, there has been a dramatic increase in research surrounding factors that influence children's school readiness, or preparedness that allows children to learn in a formal educational setting. It includes possessing early academic as well as cognitive and socio-emotional skills (e.g., self-regulation, emotion knowledge)…

Children with intellectual and developmental disabilities (IDD) experience significant difficulties in attention, learning, executive functions, and behavioral regulation. Emerging evidence suggests that computerized cognitive training may remediate these impairments. In a double blind controlled trial, 76 children with IDD (4-11 years) were…

Background: Individual differences in conduct problems arise in part from proneness to anger/frustration and poor self-regulation of behavior. However, the genetic and environmental etiology of these connections is not known. Method: Using a twin design, we examined genetic and environmental covariation underlying the well-documented correlations…
