Abstract

Examined the effects of a series of 8 short-term separations from life-long partners on 29 adolescent rhesus monkeys, some of whom had previous separation histories. In 3 experiments, groups of Ss were observed during a 6-wk baseline period, during a series of 8 wkly cycles of 4 days of separation and 3 days of reunion, and during a 6-wk recovery period. Ss included 7 31/2-yr-old peer-reared Ss, 4 groups of 4 11/2-yr-old peer-reared Ss (Exp II), and 6 3-4 yr old nuclear-family-reared Ss (Exp III). The changes seen within reunion periods, across repeated reunions, across repeated separations, and from baseline to recovery were all generally consistent with predictions from R. L. Soloman and J. D. Corbit's (see record 1974-26855-001) opponent-process theory of affective dynamics. Results indicate that all groups of Ss showed decreases in normal socially directed activity across repeated reunions and concurrent increases in depressive or agitated/depressive behavior across repeated separations. In addition, all groups showed increases over baseline levels in some socially directed activity on Day 1 of reunion, followed by declines in some or all of the activities by Day 3 of reunion.
