We examine interhemispheric cooperation in the recognition of personally known faces whose long-term familiarity ensures frequent co-activation of face-sensitive areas in the right and left brain. Images of self, friend, and stranger faces were presented for 150 ms in upright and inverted orientations both unilaterally, in the right or left visual field, and bilaterally. Consistent with previous research, we find a bilateral advantage for familiar but not for unfamiliar faces, and we demonstrate that this gain occurs for inverted as well as upright faces. We show that friend faces are recognized more quickly than unfamiliar faces in upright but not in inverted orientations, suggesting that configural processing underlies this particular advantage. Novel to this study is the finding that people are faster and more accurate at recognizing their own face over both stranger and friend faces and that these advantages occur for both upright and inverted faces. These findings are consistent with evidence for a bilateral representation of self-faces.
我们研究了在识别个人熟知面孔时的半球间合作，这些面孔的长期熟悉度确保了左右脑面部敏感区域的频繁共同激活。自我、朋友和陌生人面孔的图像以直立和倒置的方向呈现150毫秒，呈现方式包括单侧（右侧或左侧视野）和双侧。与先前的研究一致，我们发现熟悉面孔存在双侧优势，而不熟悉面孔则没有，并且我们证明这种优势在倒置面孔和直立面孔中均会出现。我们表明，在直立方向而非倒置方向上，朋友面孔比不熟悉面孔的识别速度更快，这表明构型加工是这种特殊优势的基础。本研究的新发现是，人们识别自己的面孔比识别陌生人和朋友的面孔更快、更准确，并且这些优势在直立和倒置面孔中均会出现。这些发现与自我面孔双侧表征的证据一致。
