Abstract

Two female and 3 male infant squirrel monkeys were separated from their mothers at a mean age of 169 days. All had been group reared. The experiment entailed three 5 day periods: (1) preseparation; (2) separation; and (3) reunion. During the experiment, each infant was observed for 10 min per day. Frequency and duration measures were recorded for activity play, locomotion, object manipulation, and disturbance. Social behaviors recorded were contact play, mixed play, competition play, sex play, affiliation, display, and aggression. Changes noted during separation were depression of activity play, contact play, mixed play, object manipulation, and sex play. Affiliative behaviors and locomotion increased during separation. After reunion, locomotion and affiliation returned to baseline levels while contact play, mixed play, and object manipulation remained depressed.
