The present study examined child and school factors that might foster classroom behavioral engagement during the first year at school in a sample of 67 typically developing British 4-year-olds. The children were followed for 9 months from the summer before enrollment through the first 7 months of school. Our findings showed that effortful control…

Twenty infants were observed interacting with their mothers and fathers at home when they were 7, 8, 12, and 13 months of age. No parental preference was found in the infants' attachment behaviors. Differences were found in the infants' affiliative behaviors, in their responses to parental play, and in situations in which they were held by…

This study shows that 12-month-old infants direct more distal/affiliative behaviors to their fathers and show no preference between parents in proximal/attachment behaviors. However, with a stranger present, more proximal/attachment behaviors are directed toward the mother with no preference shown in distal/affiliative behaviors. (JMB)

Seventy 15-month-old infants were studied at home before starting child care, during adaptation (mothers present) and separation (first 9 days without mothers) phases, and 5 months later. Security of infantmother attachment was assessed before and 3 months after child care began. In the separation phase, salivary cortisol rose over the first 60…

Meta-analysis aggregated results of 40 investigations involving 2,867 children who averaged 29.6 ("SD" = 8.6) months of age when their attachments to care providers were assessed using either the Strange Situation (SS) or the Attachment Q-Set (AQS). As opposed to parents, secure attachments to nonparental care providers were less likely (using SS)…

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)

Analyses of the interaction of 45 Swedish infants with their mothers and fathers revealed that degree of paternal involvement had no effect on preferences displayed on measures of attachment and affiliative behaviors. At both eight and 16 months, infants showed clear preferences for their mothers over their fathers. (Author/RH)

A group of 3-year-old children were observed in a Strange Situation immediately prior to admission to day care and again three months later. Their behavior was compared with that of a control group, matched in all respects except for the fact that their parents had no plans to enroll them in day care. (SB)

Twenty infants were observed at home interacting with their mothers, fathers, and an unfamiliar investigator when they were 15, 18, 21, and 24 months of age. (Author/JMB)

This study examined father-infant and mother-infant relationships by observing infants and parents in their homes. The subjects were 20 infants, 10 boys and 10 girls, 7 and 8 months of age. Each infant was visited twice when both parents were at home. All visits were made by the same two persons: a male observer, who maintained a narrative account…

Disputes claims concerning the association between strange-situation behavior around 12-20 months of age and subsequent child performance. Maintains studies have precluded causal inferences about the direction and nature of effects, finding associations only when the quality of care received was stable, thus, precluding inferences about the…

This paper discusses the nature of the infant social world. Infants develop attachments to both parents. Father-child and mother-child relationships are qualitatively different. They involve different types of experiences and have different implications for the child's personality development. The fathers' sex-differentiating behavior focuses the…

Twenty 18-month-olds were observed interacting with their mothers and fathers in a structured laboratory setting. Assessed were affiliation and attachment behaviors when the infant was alone with either the mother or father or with both parents and when stranger entered. (Author/MS)

Findings from a study of 109 Israeli day-care providers suggest that they classify, label, and evaluate infant behavior in the Strange Situation procedure much like attachment theorists do. The relatively independent infants were viewed most positively and most providers preferred to interact with these infants. (SLD)

This paper is a summary of results of two overlapping longitudinal studies tracing the development of mother-infant and father-infant attachments between 7 and 24 months of age. Interaction between 10 male and 10 female infants and their parents was observed in the subjects' homes. Interaction with parents was compared to interaction with an…
