自我面孔识别的独特性

On the Uniqueness of Self-face Recognition

与识别他人的面孔相比,自我面孔识别在行为反应、种系发生、个体发展以及脑机制等方面都具有很大的独特性。行为指标方面,自我面孔识别在速度上快于识别他人的面孔;种系发生方面,只有人类和大猩猩等高级灵长类动物才具有识别自己面孔的能力;个体发展方面,儿童出生后不久即能识别他人面孔,但要在18个月左右才能表现出自我面孔识别能力;脑机制方面,神经心理学和脑成像研究结果表明自我面孔识别可能主要是右脑的功能。该领域的研究进展将为深入了解自我的形成机理提供一个新的探视“窗口”。

In comparison with the recognition of others＇ faces, self-face recognition manifests its great uniqueness in behavioral response, phylogeny, development and neural mechanism. Recognizing one＇s own face is faster than recognizing others＇ face; only human beings and chimpanzees show the ability of self-face recognition; children can distinguish different faces of other pecple before they can recognize their own face; finally, findings from neuropsychological and neuro-imaging studies suggest that self-face recognition seems to be the function of the right hemisphere. These researches offer a new “window”for studying the self.
