     Personality is a construct that describes differences between individuals in behavioral and psychological functioning. Evidence suggests that multiple dimensions of personality exist and that individual differences in these dimensions are stable across time and situation. Such stability is presumably reflected in underlying physiological processes. In the past twelve years, we have been exploring the causes and consequences of individual differences in personality in rhesus monkeys, and have examined correlates of personality in a number of domains. Our emphasis has been on Sociability, which reflects a general tendency to affiliate, and we have found, for example, that high-Sociable animals show greater immune and cardiac responsiveness to social events, such as pairings with unfamiliar animals and separations from familiar companions. These and other data to be presented support the idea of a multifactorial approach to nonhuman primate personality, and suggest that this construct can help explain variation in animals' psychological and physiological functioning.
