Abstract:
The authors obtained behavioral observations and personality ratings for 27 free-ranging Hanuman langur males. Subjects were rated using a questionnaire based on the human Five-Factor Model (FFM). Behavioral observations were taken over 5 months using an ethogram that included 50 behaviors. Principal Component Analysis (PCA) of ratings revealed AgreeablenessR, ConfidenceR, and ExtraversionR components. Each personality dimension was associated with a unique set of observed behaviors. PCA of 36 behavioral indices revealed DominanceB, InvolvementB, and ActivityB components. Bivariate correlations showed that AgreeablenessR was negatively correlated with DominanceB; ConfidenceR was positively correlated with DominanceB and InvolvementB but negatively correlated with ActivityB; and ExtraversionR was positively correlated with ActivityB. Dominance rank was positively correlated with ConfidenceR and DominanceB but negatively correlated with AgreeablenessR and ActivityB. These results highlight the comparability of behavioral coding and personality ratings and suggest that some aspects of personality structure were present in the common ancestor of Old World monkeys.
