中国学生的自我面孔识别

已有研究表明大脑右半球具有自我面孔再认的优势。为了进一步验证这个观点，该研究使用面孔识别任务，以13名右利手的中国大学生为被试，测量被试对morphing面孔的左右手反应差异。给被试呈现第一张面孔向第二张面孔的morphing过程，当被试看到morphing的面孔更像第二张面孔时报告停止。研究有两个morphing过程：一个为由自我面孔向名人面孔morphing，另一个为好朋友面孔（熟悉的）向名人面孔morphing。结果表明当用左手反应时，被试倾向于把morphing的面孔识别为自己，研究中自我面孔再认的左手优势与已有的发现一致。另外，研究还发现在一定trials条件下，熟悉面孔再认也具有左手优势，这一结果与西方被试的结果不一致，但东西方被试对熟悉面孔再认的差异与独立型自我和互倚型自我的观点一致。该文认为神经心理学有关自我的研究可能需要考虑文化和情境的复杂性。

Self-face Identification in Chinese Students

Previous research using morphed stimuli has demonstrated that the right hemisphere may be preferentially involved in self-face recognition. To test this further, we employed a face-identification task and examined hand response differences in Chinese college students. Thirteen right-handed volunteers were presented "movies" in which one face morphed into another. They were told to stop the "movies" when the face looked like the end face more than the start face. The frames of the movie were pictures in which famous faces were combined with the participants' faces (self) or their good friends' faces (familiar). The results demonstrated that when responding with the left hand, participants had a tendency to identify the morphed images as their own face. The left hand advantage of self-face recognition was consistent with previous findings. However, the left-hand advantage also existed in familiar-face recognition under certain trials, which differs with results from Western participants. This difference is consistent with the idea of an "Independent" and "Interdependent" self. We suggest that research on the self in neuropsychology may need to consider the complexity of culture and context.
