Personality, subjective well-being, and the serotonin 1a receptor gene in common marmosets (Callithrix jacchus).

Studies of personality traits in common marmosets (Callithrix jacchus) indicate that there are five or six constructs-Sociability, Dominance, Neuroticism, Openness, and two related to Conscientiousness. The present study attempted to determine whether our earlier study of laboratory-housed individua...
