Twelve juvenile bonnet macaques ( Macaca radiata ), 6 males and 6 females, were presented with color videotape recordings of 3 types of social stimuli. The stimulus animals, all unfamiliar adult conspecifics, consisted of a passive female, a passive male, and a threatening male. Subjects were observed in the presence of their mother and 1 other juvenile‐mother dyad. The juveniles showed the highest scores for contact with mother when presented with the threatening male stimulus. Similarly, subjects lipsmacked significantly more to the threatening male stimulus than to either the passive male or female. The female stimulus was approached significantly more than either the passive or threatening male. Results suggest that juvenile macaques will respond to social stimuli presented through color video recordings in a socially appropriate manner. This technique provides a new tool in the investigation of social perception in nonhuman primates.
