The relation between resumption of full-time employment by mothers of infants, and subsequent infant-mother and infant-father attachments, was examined. No relation emerged between maternal work status and the quality of infants' attachments to their mothers. (PCB)

Attempted to replicate findings of a previous study which found that mother-toddler interaction during problem solving was related to the child's prior attachment security. Examined the relationship between problem-solving interactions on the one hand, and mother-child interactions at home and infant temperament on the other. (PCB)

This study examined the differential effects of sex of parent, sex of child, and sex of stranger on infant behavior in a stranger-separation situation. Year-old infants (16 males and 19 females) from middle-class families were observed and videotaped twice, at one-week intervals, in a modification of Ainsworth's laboratory stranger and separation…

Examined relationship of maternal sensitivity and infant temperament to attachment security among Korean 1-year-olds. Found that securely attached infants showed more secure-base behaviors and compliance, enjoyed physical contact, and showed fewer fussy/difficult behaviors than did other infants. Infant gender, but not security status, related to…

The preference of the infant for mother versus father as an attachment figure and as a secure base for exploration is examined in this study. Subjects were fifteen 15-month-old infants whose mothers were their primary caregiver. The Ainsworth Strange Situation procedure was modified to permit both parents' simultaneous presence during separation…

Investigated development of face-to-face communication in infants between 1 and 14 weeks old and their mothers. Found a curvilinear development of early face-to-face communication, with increases occurring between weeks 4 and 9. When placed on a sofa, infants' face-to-face communication was longer than when they were held. Girls spent a longer…

The conditions of day care quality under which infants direct secure attachment behaviors toward their day care providers were examined. Two groups of 12- to 18-month-old infants, who were experiencing either 1:4 or 1:7 caregiver-to-infant ratios, and their day care providers, were observed while they interacted in their day care centers.…

This paper reports the effects of one hour of extra post-partum contact between mother and infant on the quality of the attachment observed when the infant was one year old. It was hypothesized that infants in the extra contact condition would be classified as securely attached while regular contact infants would be less frequently classified as…

This longitudinal study examined the interrelationship between sex of the child and sex of the parent on the expression of attachment behaviors during the child's first 2 years. Special consideration was given developmental changes in the attachment structure and the relationship of attachment to cognitive development. Ten boys and 10 girls were…

During a brief play period away from the mother, the responses of 10-month-old infants were observed as a function of two factors in a 2x2 design: first, whether the mother or the infant initiated the separation and second, whether the mother was visible or not during the separation. (Author/MS)

As part of a longitudinal study of postpartum adjustment and infant development, this study examined whether securely attached 12-month-old infants show greater object mastery motivation and social-object mastery motivation than do insecurely attached infants. Object mastery relates to infants' goal-directed behavior that is oriented toward…

This study investigates the effects of age and prior experience with age-mates on attachment behavior and exploratory play with another child. Twenty home-reared children, half between 18 and 24 months and half between 24 and 30 months, and 20 day care children, also equally divided into the two age groups, were observed in the Ainsworth strange…

This document consists of four research reports and one research note focusing on several aspects of the cognitive and emotional development of young children. The first article explores two theories of the relationship between cognition and emotion, reporting on an investigation of that relationship in a simple learning task involving 60 Japanese…

Using a question-answer format, this paper examines the concept of attachment and its importance for parents and caregivers of young children. Twenty topics are addressed through an examination of relevant theory, research findings, and clinical evidence: (1) a "who's who" list of researchers on attachment; (2) definition of attachment;…
