Background: Differential Susceptibility Theory (DST) postulates that some children are more affected--for better and for worse--by developmental experiences, including parenting, than others. Low birth weight (LBW, 1,500-2,499 g) may not only be a predictor for neurodevelopmental impairment but also a marker for prenatally programmed…

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…

This article presents theoretical arguments and supporting empirical evidence suggesting that attachment experiences in early life may be important in the later development of self-regulation and conscientious behavior. Analyses of data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth…

Much research on the quality of child care reveals it--in the case of low-quality child care--to be related to poorer child functioning, net of confounding factors, perhaps especially in the case of cognitive-linguistic performance. Recent work using data from the National Institute of Child Health and Human Development (NICHD) Study of Early…

This study examined early observed parenting and child-care experiences in relation to functioning of the hypothalamic-pituitary-adrenocortical axis over the long term. Consistent with the attenuation hypothesis, individuals (n = 863) who experienced: (a) higher levels of maternal insensitivity and (b) more time in child-care centers in the first…

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…

Background: Inconsistencies regarding developmental effects of non-maternal childcare may be caused by neglecting the possibility that children are differentially susceptible towards such experiences. Method: Interactions between difficult/negative child temperament and childcare type, quantity, and quality on teacher-rated behavior problems and…

Evolutionary-biological reasoning suggests that individuals should be differentially susceptible to environmental influences, with some people being not just more vulnerable than others to the negative effects of adversity, as the prevailing diathesis-stress view of psychopathology (and of many environmental influences) maintains, but also…

Examined observed father-infant interaction and reports of parental responsibility during infancy in 54 dual-earner and 65 single-earner families. Results indicated that personality characteristics of the father were important in predicting father's responsibility for child care in single-earner families, not in dual-earner families. Contextual…

Findings suggest that infant temperament affects the manner in which security or insecurity is expressed, but does not determine whether an infant develops a secure or insecure attachment to parent. (PCB)

To determine whether 1 or 2 dimensions of infant emotionality best characterized infant functioning, parental reports (10 months) and elicited emotion (12-13 months) were examined. Found that early positivity (12-13 months) predicted later positivity (18-20 months) better than later negativity, with the reverse being true of early negativity.…

Examined the antecedents of infant-father attachment among 136 father-son dyads using the Ainsworth and Wittig Strange Situation procedure and questionnaires. Found that fathers of secure infants were more extroverted and agreeable than fathers of insecure infants, tended to have more positive marriages, and experienced more positive emotional…

Observed parents' coparenting of 15-month-old sons to test 2 hypotheses: (1) greater differences in parents' demographic factors, personality, styles of relatedness, and child-rearing attitudes would forecast more unsupportive coparenting; and (2) the adverse effects of spousal differences would be amplified by family stress. Results supported…

Studied personality change in 34 men across the transition to parenthood to determine if measurable change in men's personalities coincides with adoption of father role, and whether this change is mediated by actual involvement in fathering. Fathers' level of involvement with sons was correlated with decreased self-esteem; level of involvement…

Background: Recent investigations suggest that experience plays an important role in the development of face processing. The aim of this study was to investigate the potential role of experience in the development of the ability to process facial expressions of emotion. Method: We examined the potential role of experience indirectly by…
