Background: Most gene-environment interaction (GXE) research, though based on clear, vulnerability-oriented hypotheses, is carried out using exploratory rather than hypothesis-informed statistical tests, limiting power and making formal evaluation of competing GXE propositions difficult. Method: We present and illustrate a new regression technique…

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…

Core findings of the ongoing National Institute of Child Health and Human Development study of early child care and youth development through the end of the primary-school years are summarized, highlighting the fact that both positive effects of good quality care on cognitive-linguistic-academic functioning and negative effects of extensive…

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…

Research Findings: This study, undertaken in Nicosia, Cyprus, sought to evaluate some of the hypothesized developmental benefits of developmentally appropriate practices (DAP) by investigating how the pedagogical attitudes and practices of Greek/Cypriot parents (n = 142) and teachers (n = 16) relate to 4- to 7-year-olds' (n = 142) social-emotional…

Assessed effects of maternal employment on socioemotional development of young children. After controlling for differences at time of child's birth, found that children whose mothers worked full-time beginning in child's first or second year scored more poorly on composite measure of adjustment than did children of mothers who were not employed…

Aimed (1) to determine whether a time sampling, frequency-count procedure for assessing mother-infant interaction could capture a set of theoretically important dimensions, and (2) to chronicle both ability and change within the mother-infant relationship. A total of 74 dyads were observed when infants were 1, 3, and 9 months of age. (Author/RH)

Examined the links between children's relationships with their parents at one and three years and their relationships with a friend at five years. Positive and secure parent-child relationships were associated with children's positive friendships and negative family relationships with negative friendships. Several counterintuitive findings…

Reviews research on intellectual, emotional, and social development of children in day care. (RH)

Evidence concerning the developmental correlates of nonmaternal care in the first year of life are examined with respect to infant-mother attachment and subsequent social development. Even though the evidence is not without its inconsistencies, a circumstantial case, consistent with attachment theory, can be made that extensive infant day care…

Examines evidence concerning developmental correlates of nonmaternal care in the infant's first year with respect to infant-mother attachment and subsequent social development. Concludes that more than 20 hours a week of nonmaternal care may be a risk factor contributing to developmental difficulties. (SKC)

Makes two assumptions in examining the transition to kindergarten: (1) multiple risk factors are expected to predict early school social and academic success or failure; (2) classroom and playground experiences will exacerbate or mitigate the effects of those risk factors. Notes the importance of identifying child, family, child care, and…

Reviews three aspects of literature on parental and nonparental child care pertaining to socioemotional development during infancy, preschool, and school-age years: (1) determinants of parenting and factors influencing parental behavior and parent-child interactions; (2) link between parent-child interactions and child development; and (3) effects…
