In this article, the author synthesizes research from several disciplines to shed light on play's central role in healthy development. Gordon builds on research in attachment theory that correlates secure attachment in infancy with adult well-being to demonstrate how playfulness might be a lifelong outcome of secure attachment and a primary…

This longitudinal investigation of 84 infants examined whether the effect of 12-month attachment on 18- and 24-month exploration and sociability with unfamiliar adults varied as a function of newborn irritability. As expected, results revealed an interaction between attachment (secure vs. insecure) and irritability (highly irritable vs. moderately…

The stability of eight attachment behaviors was investigated in two samples of infants. One sample observed at 10 and 14 months of age, the other sample at 14 and 18 months. For each testing period, the infants were observed during two sessions: (a) in the presence of the mother; and (b) before, during, and after a brief separation experience.…

A model of infant social behavior is developed which incorporates attachment to the familiar and fear of strangers as well as detachment from the familiar and exploration of the stranger. (JMB)

This longitudinal study of 10 infants in a day care nursery traces the development of recognition and attachment to a primary caregiver from approximately 3 1/2 months of age (shortly after enrollment in the program) through the end of the first year. Monthly assessments of about 10 minutes each, on two successive days, were made of the infant's…

The second of a four-part series on the development of infants and toddlers, this article reviews current research on social and emotional development during the first two years and provides a selected list of activities designed to promote infants' optimal development. Attachment behavior and affective behavior are two major topics explored. (EV)

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…

Describes research with 12- to 18-month-old infants (N=108) determining whether the quality of an infant's attachment to his/her primary caregiver could predict the nature of his/her emerging personality. (CS)

This article examines the view of infants as passive recipients of social stimulation. It is argued that progress in the understanding of sociopersonality development will be achieved only when the competence of infants and the multidimensionality of the infant social world are acknowledged. (MS)

Describes characteristics of the attachment behavior of 10 infants blind from birth. Behaviors studied were smiling, discriminating tactile behaviors, stranger avoidance and distress, and separation and reunion behaviors. (BRT)

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…
