Rhesus monkeys were observed longitudinally from 6 to 20 years of age, the period encompassing early to late adulthood in this species. Repeated-measures analyses of the monkeys' behavioral repertoire revealed 3 quite different pictures of the aging process. First, there were significant systematic changes in the levels of many categories of behavior with increasing age, although the direction and timing of change varied from category to category. Second, for most categories, individual differences among the monkeys were highly stable from early to late adulthood. Finally, there was remarkable consistency within individual behavioral profiles across the entire study such that each monkey retained its distinctive behavioral features (personality) throughout its adult years. Thus, aging in rhesus monkeys is characterized by both continuity and change.
