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…

Analyzed stability and change in late adolescent attachment relations and the interrelationship among attachment, separation-individuation, and college adjustment variables. Results of two studies suggested stability in attachment to parents, over time, for both men and women. Security of attachment was inversely related to independence from…

Examined whether attachments to family and school reduced five forms of adolescent deviance (smoking, drinking, marijuana use, delinquency, and violent behavior). Found that adolescent attachments to family and school reduced overall frequency, prevalence, and intensity of deviant involvement, regardless of community context, gender, or ethnic…

This document provides data from an ongoing longitudinal study of the degree of continuity in individual development over time and describes the complexities involved in efforts to determine the nature of individual continuity. Findings from the Minnesota Longitudinal Study of children in a day camp provide evidence for continuity in individual…

The development of and relationship between early language, symbolic play, sensorimotor skills, and social development were examined in a longitudinal study conducted in Japan with two young autistic males who were observed from the approximate ages of 2 to 4 years in clinic, day care, and home settings. One child acquired speech; the other did…

Studies on the effects of early day care can be characterized according to two distinct research trends. In the first, which occurred during the 1960s and 1970s, the principal issue was whether day care had any inevitable and negative consequences for the child and, particularly, the mother-child attachment. The second, more recent, trend has been…

Nearly 30 years ago, research showed that preschool children reared by parents with differing parenting attitudes or styles, differed in their degrees of social competence. To test this theory, a two-year study was conducted. During "Year 1," 2,250 high school seniors and 406 university freshmen from the middle South were surveyed…

Four studies tested a theory that high interparental conflict increases child mental health risk by shaking children's sense of security in the family. Findings showed that children's fear, avoidance, and involvement were prominent responses, especially relative to reactions predicted by other theories. Interparental conflict related to greater…

A longitudinal investigation focused on the etiology of psychiatric and behavioral disorders in a sample of 190 children at risk for developmental problems. Data collection began during pregnancy and included assessments of: (1) parental personality, intelligence, and parenting attitudes; (2) parent-child interaction and relationship quality; (3)…

This intensive longitudinal study of mother-infant interaction during the first year of life focuses on the development of attachment. Data on 26 middle-class families were collected by five methods: (1) naturalistic observation of each mother-infant pair during 4-hour home visits, which occurred at 3-week intervals from the infants' 3rd to 54th…

Examined potential differences in psychological correlates between mothers with high and low levels of separation anxiety when their children were 8 months, 3.5 years, and 6 years of age. Mothers with extremely high levels of anxiety about short-term separation from their six year olds tended to have higher levels of depressive symptomatology.…

Assessed 8-year-olds' perceptions of emotional support from mother and best friend. Found that preschool attachment security predicted age-8 maternal-support perceptions better than did mother's behavior. Identification of best friends as part of the support network related positively to social competence. The more insecurely attached children…

Investigates how the age of entry into regular group day care influences short-term behaviors expressing well-being or discomfort in the day care environment. Finds that children entered at two particular ages displayed difficult reunions with their mothers and were less resistant to frustration; children entered at another age showed lower…

This study investigates the father's contribution to child development in the context of a triadic family constellation, integrating data that parallel previous investigations of fathers: differences in children's behavior to mother and father, differences in mothers' and fathers' behavior to the child, and correlations between parental and child…

Using multiple regression analysis, the associations of delinquency with IQ and achievement scores, general school success, school attachment, preschool intervention and gender were explored for a group of high-risk Black students. Findings are discussed in terms of Hirschi's social bonding theories and early schooling effects on adolescent life…
