Maternal sensitivity during an observed mother-child clean-up task at 18 months and maternal sensitivity during an observed mother-child free-play task at 18 months were tested as independent predictors of child internalizing symptoms, externalizing symptoms, social competence, and language development at 24 months. Participants (n = 292 mothers)…

This study considered the quality and stability of infant and toddler nonparental child care from 6 to 36 months in relation to language, social, and academic skills measured proximally at 36 months and distally at kindergarten. "Quality" was measured separately as caregiver-child verbal interactions and caregiver sensitivity, and…

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…

Associations between maternal sensitivity to infant distress and nondistress and infant social-emotional adjustment were examined in a subset of dyads from the NICHD Study of Early Child Care (N = 376). Mothers reported on infant temperament at 1 and 6 months postpartum, and maternal sensitivity to distress and nondistress were observed at 6…

This commentary endorses J. Kagan's (2008) conclusion that many of the most dramatic findings on early perceptual, cognitive, and social competencies are ambiguous. It supports his call for converging research operations to disambiguate findings from single paradigms and single response indices. The commentary also argues that early competencies…

A differential susceptibility hypothesis proposes that children may differ in the degree to which parenting qualities affect aspects of child development. Infants with difficult temperaments may be more susceptible to the effects of parenting than infants with less difficult temperaments. Using latent change curve analyses to analyze data from the…

The link between the quality of attachment in infancy and the quality of play and problem-solving behavior at age two years was examined in 48 infants. (Author/JMB)

The security of attachment between 18-month-old infants and their mothers was assessed in the Ainsworth strange situation (SS). Infant dyads created according to their SS classification were observed in unstructured peer interaction. Results indicated a relationship between quality of infant-mother attachment and infant peer competence. (JMB)

Ratings of social behavior and scores on the Bayley Mental Development Index (MDI) were obtained for 33,685 infants, eight months of age. A composite measure of sociability correlated .23 with total MDI scores, .26 on the socially loaded items, and .17 with the nonsocial items. (Author/RH)

Infant joint attention has been observed to be related to social-emotional outcomes in at-risk children. To address whether this relation is also evident in typically developing children, 52 children were tested at 12, 15, 24, and 30 months to examine associations between infant joint attention and social outcomes. Twelve-month initiating and…

This study analyzed the social interaction sequences and behavioral components of social interaction in two toddler playgroups across a 7-month period. Playgroup number 1 was composed of 6 male toddlers aged 1 year and playgroup number 2 was composed of 6 male toddlers aged 16 months. (JMB)

Two studies assessed the positive affective correlates of secure attachment in infancy and the relation between secure attachment in infancy and competence in the peer group at 3 1/2 years of age. (JMB)

Using the Ainsworth Strange Situation Procedure, a study examined the interrelations between dimensions of emotion and social interactive behaviors to explore the regulatory role of each in mother-infant interaction and how these roles may change in the second year. (HOD)

Forty middle-class mothers and their 12-month-old infants participated in an examination of the extent to which infant sociability and home experiences were correlated with cognitive capacity. (JMB)

Evaluated changes in mothers' interactive behaviors with infants from 6 to 40 months who were medically high risk, medically low risk, very low birthweight preterm, or full-term. Found that variations in mothers' responses to children's changing capabilities predicted rates of change in children's social skills. (Author/KB)
