In recent years, an increased interest in the importance of children's ability to regulate emotions in socially adaptive ways has driven considerable research on the development of emotion regulation. A widely studied emotion regulation strategy known as "expressive suppression" (ES), in which a person attempts to conceal…

We investigated longitudinal relations between children's sleep and symptoms of depression, anxiety, and anger/aggression. We expected that initial sleep problems and increases in these problems over time would be associated with worse adjustment outcomes. The study had 3 waves with 1-year lags. At Time 1 [T1], 128 girls and 123 boys (M age =…

Research on differential susceptibility to rearing suggests that infants with difficult temperaments are disproportionately affected by parenting and child care quality, but a major U.S. child care study raises questions as to whether quality of care influences social adjustment. One thousand three hundred sixty-four American children from…

The purpose of this study was to examine the frequency and correlates of cross-racial/ethnic friendships.

Studied relationship of temperament and same-sex peer interaction with gender differences in adjustment. Found that highly arousable boys who played with same-sex peers had increased problem behaviors. Arousable girls who played with other girls were relatively unlikely to show problem behaviors. The arousability and same-sex peer interaction…

Tested a model linking family financial resources to adjustment among African American 6- to 9-year olds with single, rural, Southern mothers. Found that inadequate financial resources related to mothers' depression and low self-esteem. Self-esteem was linked with family routines and mother-child relationship quality. Child self-regulation…

Used a variety of family factors to predict development of children who averaged 30 hours of nonparental care per week for each month of their lives and of those who experienced no more than 10 hours of nonparental care per week. Multivariate analyses provided no evidence that family factors predicted outcomes differently for these two groups.…

Studied after-school activities of third graders for two years. Found that children attending after-school programs spent more time on academic and extracurricular activities; children in informal care spent more time watching television and "hanging out." Sex differences were reported in the type of activities. Time spent in activities was…
