有证据表明，右额叶皮层优先参与自我面孔识别。为了进一步验证这一点，我们采用了人脸识别任务，并检查了手的反应差异（N = 10）。名人的照片与参与者的脸（自己）和他们的同事的脸（熟悉）的照片相结合。这些图像被呈现为一部“电影”，其中一张脸变成了另一张脸。在第一个指令集下，电影以参与者的脸或同事的脸开始。这些序列逐渐演变成一张著名的脸。当被告知当序列中的面孔变得出名时停止电影时，当电影由自我面孔组成时，参与者用他们的左手做出反应时，一个明显较晚的“框架”被确定。当电影以著名的面孔开始，当电影变成他们自己或他们熟悉的同事的形象时，参与者必须停止电影（指令集2），在“自我：左手”条件下识别出明显更早的帧。这些数据表明，当右脑优先进入时，参与者倾向于将图像识别为自己的图像。(C)2000爱思唯尔科技有限公司版权所有。
Evidence has indicated that the right frontal cortex is preferentially involved in self-face recognition. To test this further, we employed a face identification task and examined hand response differences (N = 10). Pictures of famous faces were combined with pictures of the participants' faces (self) and their co-workers' faces (familiar). These images were presented as a 'movie' in which one face transformed into another. Under the first instruction set, the movies began with either the participant's face or a co-worker's face. and the sequences gradually morphed into a famous face. When told to stop the movie when the face in the sequence became famous, a significantly later 'frame' was identified when the movies were composed of self-faces and the participants responded with their left hand. When the movies started with the famous faces and participants had to stop the movie when it became their own or their familiar co-worker's image (Instruction set 2), a significantly earlier frame was identified in the 'Self: Left hand' condition. The data suggest that participants are inclined to identify images as their own when the right hemisphere is preferentially accessed. (C) 2000 Elsevier Science Ltd. All rights reserved.
