Finds that when mothers were attentive infant dyads composed of consistent partners interacted more than stranger dyads. Suggest that withdrawal of maternal attention may be equivalent to physical separation by a…

This experiment tested the theoretical predictions concerning the patterns of visual fixation to representations of familiar and unfamiliar persons during the second quarter of the first year of life. Subjects were twelve 4-month-old and twelve 6-month-old infants. (Author/SB)

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)
