Abstract

Social relationships vary in content, quality, and patterning. Most researchers focus on whether and how non-dispositional factors, including age, sex, kinship, and rank predict variance in the content, quality, and patterning of relationships. However, within a species, these factors do not always predict partner choice. We examined whether similarity in any of five personality traits --- Assertiveness, Openness, Neuroticism, Sociability, and Attentiveness --- independently contributed to variation in the affiliative and agonistic relationships of pairs of brown capuchin monkeys. Capuchins that were more similar in Neuroticism had higher affiliative relationship scores, while capuchins that were more similar in Sociability shared overall higher quality relationships (i.e. the difference between the dyad‟s affiliative and agonistic scores). These effects were independent of age, sex, kinship, and rank, suggesting that certain aspects of the psychology of these animals may contribute uniquely to the quality of their social relationships.
