AbstractThis dissertation consists of two studies: the first focuses on reliability of chimpanzee personality and subjective well-being (SWB) scores, the second on validating those scores by comparing them to subjective assessments of behavior in dyads. The first measured reliability of scores of personality and subjective well-being (SWB) across ten years. Dominance rank, and the Dominance and Extraversion Factors significantly correlated between time points. In the second study, I investigated the impact of personality, SWB, and demographic characteristics on individual variation in dyadic-level individual behavior. Age predicted likeability in females, and age and rank predicted likeability in males. Neither personality factors nor SWB were correlated to likeability. An Affable domain scale and an Agonistic domain scale were constructed from the personality items. The Affable domain scale correlated with chimpanzees who were scored high neutral in social interactions, and the agonistic scale correlated with low neutral score in social interactions.
