Videotaped infants with extensive day-care experience, and their mothers during "Strange" situation procedures. Compared behavior with profiles published in Ainsworth et al. (1978) for differences. Found three distinct groups of infants: securely-attached (largest group), insecurely attached (smallest group), and infants not disturbed by…

Describes a longitudinal research project designed to study infants' and young children's adaptation process and to determine how this process is related to a child's length of time in day care and his/her developmental stage. Particular attention is given to the recurrence of similar behaviors at different stages of development. (Author/RH)

Relationships between day care and attachment were assessed with alternative procedures: (1) hypothesized normal patterns of attachment were tested naturalistically in day-care centers; (2) day-care and home-reared children were compared in a laboratory setting. (Author/MP)

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…

Part of a longitudinal study of women and their first-born children who have different employment and day care experiences during the children's first three years of life, this study focuses on the socioemotional development of children at 18 months of age, who had received at least nine months of continuous day care. Particular attention is given…

Maintains that it is premature to conclude that Q-Sort is preferable to Strange Situation for the assessment of attachment security of infants in day care. (BB)
