We examined the role of the teacher-child relationship quality (close, dependent, and conflictive) on preschoolers' (N=95) academic readiness for kindergarten, and we tested children's prosocial and aggressive behavior and peer group exclusion as mediators of this relation. A unique feature of this study is the ethnically and socio-economically…

To assess the degree to which a mand repertoire that was taught to children with autism would generalize from adults to peers, three preschool-aged children diagnosed with Autism were first taught to mand with adult instructors, and then were tested for generalization across three subsequent phases that involved parents, siblings, and peers.…

This dissertation describes how the medical categories of Attention Deficit Disorder (ADD) and Reading Disability (RD) have become commonsense ways to understand educational problems. I explore historical precursors of ADD and RD followed by a report on fieldwork I conducted in a first grade classroom of mostly Latino and low-income children. I…

Researching the epidemiology and estimating the prevalence of fetal alcohol syndrome (FAS) and other fetal alcohol spectrum disorders (FASD) for mainstream populations anywhere in the world has presented a challenge to researchers. Three major approaches have been used in the past: surveillance and record review systems, clinic-based studies, and…

Background: Previous research has reported on the effectiveness of the Signposts program for supporting families of children with an intellectual disability and difficult behaviour (Hudson et al., 2003; Hudson, Cameron, & Matthews, 2008). This paper reports on an investigation of the extent to which child characteristics moderate the…

A growing body of evidence indicates that for some children, early incidences of challenging behaviors are predictors of later difficulties. These incidences of challenging behaviors may predict mental health issues, social adjustment issues and/or increased challenging behaviors that will impede school success and impact transition to adult life…

School-based approaches to addressing aggression in the early grades have focused on explicit curriculum addressing social and emotional processes. The current study reviews research on the distinct modes of aggression, the status of current research on social and emotional processing relevant to problems of aggression amongst young children, as…

Research examining the influence of social relationships on child outcomes has seldom examined how individuals derive social capital from more than one context and the extent to which they may benefit from the capital derived from each. We address this deficit through a study of child behavior problems. We hypothesize that children derive social…

In a 19-year longitudinal study, the 15% most inhibited and the 15% most aggressive children at ages 4-6 years were followed up until age 23 years and were compared with controls who were below average in preschool inhibition or aggressiveness. As adults, inhibited boys and girls were judged as inhibited by their parents and showed a delay in…

Background: Mental health problems comprise an international public health issue affecting up to 20% of children and show considerable stability. We aimed to identify child, parenting, and family predictors from infancy in the development of externalising and internalising behaviour problems by age 3 years. Methods: "Design"…

Youth who initiate sexual intercourse in early adolescence (age 11-14) experience multiple risks, including concurrent adjustment problems and unsafe sexual practices. The current study tested two models describing the links between childhood precursors, early adolescent risk factors, and adolescent sexual activity: a cumulative model and a…

Neurobiological models propose an evolutionary, vertical-integrative perspective on emotion and behavior regulation, which postulates that regulatory functions are processed along three core brain systems: the brainstem, limbic, and cortical systems. To date, few developmental studies applied these models to research on prenatal and perinatal…

The etiology of autism is complex, consisting of unknown genetic and environmental factors. Previous studies have revealed that maternal age is increased in autism compared to controls, making it a possible risk factor. This study examined the effects of maternal age on autism severity using IQ as a measure of cognitive severity and selected…

A community-based intervention program was tested with 181 children ages 6-12 and their mothers exposed to intimate partner violence during the past year. A sequential assignment procedure allocated participants to 3 conditions: child-only intervention, child-plus-mother intervention (CM), and a wait-list comparison. A 2-level hierarchical linear…

Although it is commonly accepted that dyslexic children have auditory phonological deficits, the precise nature of these deficits remains unclear. This study examines potential pitch processing deficit in dyslexic children, and recovery after specific training, by measuring event-related brain potentials (ERPs) and behavioural responses to pitch…
