Data collected over an 11 year period were analyzed for behavioral constancy, reaction to environmental change, and the differential influence of environment and genetics in a group of captive chimpanzees using the framework of the Five Factor Model of Personality. Results suggested environment was a more influential factor in behavioral production, although expected reactions of specific individuals were not evidenced. Improvements upon this research include use of a more chimpanzee-specific personality model and more detailed data collection to support more precise conclusions regarding behavioral etiology.
