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 male 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.
12只幼年冠毛猕猴（食蟹猴），6只雄性和6只雌性，被呈现了3种类型社会刺激的彩色录像带。刺激动物均为不熟悉的成年同种个体，包括一只被动的雌性、一只被动的雄性和一只具有威胁性的雄性。在其母亲和另一对幼年-母亲二元组在场的情况下观察受试猕猴。当呈现具有威胁性的雄性刺激时，幼年猕猴与母亲接触的得分最高。同样，受试猕猴对具有威胁性的雄性刺激的咂唇行为明显多于对被动雄性或雌性刺激的咂唇行为。与被动或具有威胁性的雄性相比，受试猕猴接近雌性刺激的次数明显更多。结果表明，幼年猕猴会以符合社会规范的方式对通过彩色录像呈现的社会刺激做出反应。这项技术为研究非人类灵长类动物的社会认知提供了一种新工具。
