Rumination to negative affect has been linked to the onset and maintenance of mood disorders in adults as well as children. Responses to positive affect have received far less attention thus far. A few recent studies in adults suggest that responses to positive affect are involved in the development of both depressive and hypomanic symptoms, but…

This study describes temperament, personality, and problem behaviors in children with Attention-Deficit Hyperactivity Disorder (ADHD) aged 6 to 14 years. It targets differences between an ADHD sample (N=54; 43 boys) and a large community sample (N=465; 393 boys) in means and variances, psychometric properties, and covariation between traits and…

This longitudinal study examined processes that mediate the association between maternal depressive symptoms and peer social preference during the early school years. Three hundred and fifty six kindergarten children (182 boys) and their mothers participated in the study. During kindergarten, mothers reported their level of depressive…

The current study examined the moderating influence of observed parental emotion socialization (PES) on self-medication in adolescents. Strengths of the study include the use of a newly developed observational coding system further extending the study of PES to adolescence, the use of an experience sampling method to assess the daily covariation…

This study examined whether children exposed to prenatal smoking show deficits in "hot" and/or "cool" executive functioning (EF). Hot EF is involved in regulation of affect and motivation, whereas cool EF is involved in handling abstract, decontextualized problems. Forty 7 to 9-year-old children (15 exposed to prenatal smoking, 25 non-exposed)…

Many studies point to the importance of social information processing mechanisms in understanding distinct child behaviors such as aggression. However, few studies have assessed whether parenting might be related to such mechanisms. This study considers how aversive forms of parenting (i.e., corporal punishment, psychological control) as well as…

The present study prospectively investigated early temperamental profiles and their associations with autistic symptoms in high-risk infants (N = 138) with an older sibling with autistic spectrum disorder (ASD) and low-risk infants (N = 73) with no family history of ASD. Children who were diagnosed with ASD at 36 months were distinguished from…

The applicability of the tripartite model of emotion, which distinguishes the shared aspect of depression and anxiety, negative affect (NA), from their respective specific components of low positive affect (PA) and physiological hyperarousal (PH), was examined in 472 elementary and high school students. The relations among depression, anxiety, and…

We examined children's behavioral coping in response to an "in vivo" peer rejection manipulation. Participants (N = 186) ranging between 10 and 13 years of age, played a computer game based on the television show "Survivor" and were randomized to either peer rejection (i.e., being voted out of the game) or non-rejection control. During a five-min.…
