迄今为止，事实证明很难证明大猩猩具有镜像自我识别能力。然而，大猩猩表现出明显的凝视厌恶，这可能会阻止它们花足够的时间探索镜像以了解它们是反射的来源。还有人提出，观察者的存在可能会抑制大猩猩进行标记导向的行为。为了克服目光厌恶的问题，我们使用了 Anderson st Roeder (1989, Primates, 30, 581-587) 开发的斜镜装置，该装置可以防止国家动物园里的两只大猩猩与它们的倒影进行直接目光接触。为了反驳观察者抑制假说，我们使用摄像机对这些动物进行了标记测试。尽管在一系列四项实验中解决了这些问题和其他问题，但大猩猩并没有表现出令人信服的自我识别证据，即使在镜子暴露超过四年之后也是如此。 (C) 1999 动物行为研究协会。
To date, it has proven difficult to demonstrate mirror self-recognition in gorillas. However, gorillas display pronounced gaze aversion that may prevent them from spending a sufficient amount of time exploring their mirror images to understand that they are the source of their reflections. It has also been suggested that the presence of observers may inhibit gorillas from engaging in mark-directed behaviours. To overcome th problem of gaze aversion, we used an angled-mirror apparatus developed by Anderson st Roeder (1989, Primates, 30, 581-587) that prevented two gorillas at the National Zoological Park from making direct eye contact with their reflections. To counter the observer inhibition hypothesis, we conducted mark tests on these animals using video cameras. Despite addressing these and other concerns in a series of four experiments, the gorillas did not show compelling evidence of self-recognition, even after over 4 years of mirror exposure.
