为了评估Heyes（1994）的说法，即黑猩猩无法使用镜像信息来获取有关自我的信息，否则无法获得有关自我的信息，我们将两个不同年龄组的黑猩猩（3岁和7至10岁）暴露在镜子和同类的视频图像中。他们对这些刺激的反应被录制下来，然后由一位训练有素的观察者对自我识别的行为指数进行评分，但该观察者对研究的目的和条件一无所知。某些类型的行为（偶然的面部和身体运动）明显受到黑猩猩所看到的刺激类型的影响，但不受年龄的影响;然而，其他行为（自我探索）受到年龄的影响，以及动物所看到的刺激类型。结果表明，与自我探索行为不同，偶然的面部和身体动作本身可能不是自我识别的可靠指标。
To evaluate Heyes's (1994) claim that chimpanzees are incapable of using mirrored information to obtain otherwise unavailable information about the self, we exposed two different age groups of chimpanzees (3-year-olds and 7-to 10-year-olds) to mirrors and video images of conspecifics. Their reactions to these stimuli were videotaped and were later scored for behavioral indices of self-recognition by a trained observer who was blind to the purpose and conditions of the study. Some types of behavior (contingent facial and body movements) were clearly influenced by the type of stimulus that the chimpanzees were viewing but not by age; however, other behaviors (self-exploration) were affected by age in conjunction with the type of stimulus the animals were viewing. The results suggest that, unlike self-exploratory behavior, contingent facial and body movements may not, by themselves, be reliable indicators of self-recognition.
