title: Experimental analyses of body image in the chimpanzee.
abstract: It is difficult to study body image in animals. In this study, it is assumed that the perception of the body of others reflects body image. The perception of the human face was examined in a series of six experiments with a chimpanzee. Delayed-matching-to-sample tasks were employed. Although the chimpanzee mastered the tasks and showed transfer of performance to new faces, subtle changes in the matching face resulted in the deterioration of performance. Responses of the chimpanzee were often controlled by factors other than the facial stimuli. Thus, although the chimpanzee has a body image as humans do, it may not be as clear and as segmented.
