我们描述了圈养出生的黑色簇耳狨猴（Callithrix penicillata）的行为，这些行为是通过短暂暴露于三种潜在的标本剥制掠食者（caracara hawk、Polyborus plancus;响尾蛇，Crotalus durissus; oncilla，Leopardus tigrina）和毛绒玩具而引起的。对于四种刺激中的每一种，我们将受试者提交给分为三个连续间隔的9分钟试验：4分钟暴露前基线观察，1分钟刺激暴露和4分钟暴露后观察期。我们将刺激物放置在每个受试者的笼子前面，并将试验录像用于行为分析。在暴露于潜在的动物标本的捕食者，我们听到的tsik-tsik发声和报警行为。暴露后，只有猫引起了这些反应。所有刺激引起的观察反应，虽然只有在曝光间隔。三个试验间隔之间的进一步比较表明，在暴露期间接近猫所花费的时间减少，而当受试者在同一时期暴露于鹰或蛇时，接近度增加。两者合计，暴露于动物标本化的钉螺期间和之后的行为反应表明，这种刺激能够诱导强烈和持久的情感反应，在Callithrix penicillata。
We describe the behavioral repertoire of captive-born black tufted-eared marmosets (Callithrix penicillata) elicited by brief exposures to three potential mounted taxidermized predators (caracara hawk, Polyborus plancus; rattlesnake, Crotalus durissus; oncilla, Leopardus tigrina), and a stuffed toy. For each of the four stimuli, we submitted the subjects to a 9-min trial divided into three consecutive intervals: a 4-min pre-exposure baseline observation, a 1-min stimulus exposure, and a 4-min postexposure observation period. We positioned stimuli in front of each subject home cage, and video-taped trials for behavioral analysis. During exposures to the potential taxidermized predators, we heard tsik-tsik vocalization and alarm behavior. After exposures, only the cat induced these reactions. All stimuli elicited observational reaction, albeit only during exposure intervals. Further comparisons between the three trial intervals indicated a decrease in the time spent in proximity to the cat during exposures, while an increase in proximity occurred when subjects were exposed to either the hawk or snake for the same period. Taken together, the behavioral responses during and after exposures to the taxidermized oncilla suggest that this stimulus is capable of inducing strong and persistent emotional reactions in Callithrix penicillata.
