In this Norwegian study, bidirectional relations between children's behavior problems and child-teacher conflict and closeness were examined, and the possibility of moderation of these associations by child-care group size was tested. Eight hundred and nineteen 4-year-old children were followed up in first grade. Results revealed reciprocal…

The hypothesis was tested that the new open-group Norwegian day-care centers would more than traditionally organized centers negatively affect (a) current and (b) future teacher-child relationships, and (c) the developmental legacy of preschool problem behavior. The focus was on eight hundred and fifty 4-year-olds from 153 centers who were…

Extensive exposure to nonparental child care during the first 4.5 years of life has been demonstrated in some American studies to negatively affect children's socioemotional functioning. Data from 935 preschool children who averaged 54.9 (SD = 3.0) months of age, from Trondheim, Norway were used to examine whether such negative effects, would…

Data from 508 Caucasian children in the NICHD Study of Early Child Care and Youth Development shows that the DRD4 (but not 5-HTTLPR) polymorphism moderates the effect of child-care quality (but not quantity or type) on caregiver-reported externalizing problems at 54 months and in kindergarten and teacher-reported social skills at kindergarten and…

Effects of early child care on children's functioning from 4 1/2 years through the end of 6th grade (M age=12.0 years) were examined in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (n=1,364). The results indicated that although parenting was a stronger and more consistent predictor of…

The influence of maternal stimulation on infant exploratory behavior was examined in both a cross-sectional/ correlational study and an experimental study, in order to overcome the limitations on making causal claims that attend most research into maternal influence on infant development.

Data from 918 children from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care were examined to test the interrelation of attachment and attentional performance and 2 known risks for poor attentional performance: male gender and social-contextual adversity. Attachment was measured using the Strange…

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…

Examined parent-child interaction during toddlers'"terrible twos" stage. Found that families experiencing difficulty could be identified, troubled behavior could be predicted based on family ecology, and families at moderate and high contextual risk were more likely to experience troublesome behavior when the child experienced 20 or more hours per…

The concept of reproductive strategy is applied to the study of childhood experience and interpersonal development to develop an evolutionary theory of socialization. The relationship between this theory and prevailing theories of socialization is considered, and research consistent with the evolutionary theory is reviewed. Discusses directions…
