我们通过让参与者选择两个镜像对称的嵌合体图像(由面孔照片的左半部或右半部组成)中的哪一个看起来更像原始图像，来研究熟悉程度对人们感知面部相似程度的影响。在不同的试验中，参与者对自己的脸和密友的脸做出了这个判断；其中一半与原作的真实形象相匹配，另一半与原物的镜像相匹配。在与朋友的脸以熟悉的方位进行匹配的情况下，超过80%的参与者选择左侧合成的照片更像原来的照片，而只有62%的人在匹配镜像时表现出相同的左侧偏向。这一差异是显著的，这一结果与第二个实验形成了鲜明对比，在第二个实验中，不熟悉面孔的参与者在与真实或镜像颠倒的图像进行匹配时，表现出类似的左侧偏见。结果表明，对于非常熟悉的面孔，知觉不对称保留在我们的长期记忆中。虽然与自我形象的匹配也显示出熟悉的效果，但在这种情况下的数据显示出较少的知觉不对称证据，并与最近关于自己面部表征的研究进行了讨论。(C)2005 Elsevier Inc.保留所有权利。
We investigated the effect of familiarity on people's perception of facial likeness by asking participants to choose which of two mirror-symmetric chimeric images (made from the left or right half of a photograph of a face) looked more like an original image. In separate trials the participants made this judgment for their own face and for the face of a close friend; half of them matched to a true image of the original and half matched to a mirror image of the original. In the case of matching to a friend's face presented in the familiar orientation, over 80% of participants chose the left-left composite to be a better likeness to the original, whereas only 62% showed the same left-side bias when matching to a mirror image. The difference is significant, and the result contrasts markedly with a second experiment where participants who were unfamiliar with the faces showed comparable left-side biases when matching to true or mirror reversed images. The result suggests that perceptual asymmetries are retained in our long-term memory for highly familiar faces. While matching to images of self also showed an effect of familiarity, the data in this condition show less evidence of perceptual asymmetry and are discussed in relation to recent research on the representation of one's own face.
