Cross-sectional research shows that adolescents' social media use (SMU) and attention deficit hyperactivity disorder (ADHD)-symptoms are related, but it is unclear whether this relation is explained by SMU intensity or by addiction-like SMU problems. Also, due to the lack of longitudinal studies, the direction of this relation remains unknown.…

Mobile phones and other wireless devices that produce electromagnetic fields (EMF) and pulsed radiofrequency radiation (RFR) are widely documented to cause potentially harmful health impacts that can be detrimental to young people. New epigenetic studies are profiled in this review to account for some neurodevelopmental and neurobehavioral changes…

This study tests the hypothesis that links between contextual risk and children's outcomes are partially explained by differential parenting. Using multi-informant measurement and including up to four children per family (M[subscript age] = 3.51, SD = 2.38) in a sample of 397 families, indirect effects (through maternal differential…

Used NICHD Early Child Care data to examine effects of attentional persistence on relationship of infant negative emotionality to age 3 outcomes. Found that high negative emotionality related to low social competence only when attentional persistence was poor. Found no moderating effects of attentional persistence for behavior problems. High…

Investigated the Type A Behavior Pattern (TABP) in 25 boys of 6-12 years who had attention-deficit hyperactivity disorder (ADHD). ADHD boys obtained higher TABP Total and Impatience- Aggression scores than normal boys. ADHD boys' scores were associated with a wide array of behavior problems and peer difficulties. (RJC)

Examined the everyday lives of adolescents with low, middle, or high levels of attention-deficit hyperactivity disorder (ADHD) as assessed by either parent or teen. Found that adolescents with high ADHD levels recorded more negative moods, lower alertness, more entertaining activities relative to achievement-oriented pursuits, more time with…

Examined associations between sleep and neurobehavioral functioning (NBF) in second-, fourth-, and sixth-graders. Found significant correlations between sleep- quality measures and NBF measures, particularly for the younger age group. Children with fragmented sleep were characterized by lower performance on NBF measures, particularly those…

The unique relations of effortful control and impulsivity to resiliency and adjustment were examined when children were 4.5 to 8 years old, and 2 years later. Parents and teachers reported on all constructs and children's attentional persistence was observed. In concurrent structural equation models, effortful control and impulsivity uniquely and…

The relation between cognitive and motor performance was studied in a sample of 378 children aged 5-6. Half of these children had no behavior problems; the others were selected for externalizing (38%) or internalizing problems (12%). Quantitative and qualitative aspects of motor performance were related to several aspects of cognition, after…

Examined the moderating role of individual differences in negative emotionality in the relations of behavioral and attentional regulation to externalizing problem behaviors. Found that at two ages behavioral dysregulation predicted externalizing behavior problems for children both high and low in negative emotionality, whereas prediction of…

Examined relation of different types of negative emotion and regulation and control to 55- to 97-month-olds' internalizing and externalizing problem behaviors. Found that children with externalizing problems, compared to children with internalizing problems and nondisordered children, were more prone to anger, impulsivity, and low regulation.…
