The present study investigated the extent to which a face presented in the visual periphery is processed and whether such processing can be influenced by a recent encounter in central vision. To probe face processing, a series of studies was conducted in which participants classified the sex and identity of faces presented in central and peripheral vision. The results showed that when target faces had not been previously viewed in central vision, recognition in peripheral vision was limited whereas sex categorization was not. When faces were previously viewed in central vision, recognition in peripheral vision improved even with the pose, hairstyle, and lighting conditions of these faces changed. These results are discussed with regard to possible mechanisms unpinning this exposure effect.
本研究调查了视觉外周呈现的面孔被加工的程度，以及这种加工是否会受到中央视觉中近期接触的影响。为了探究面孔加工，进行了一系列研究，让参与者对面孔在中央和外周视觉中呈现时的性别和身份进行分类。结果表明，当目标面孔之前未在中央视觉中被查看过时，外周视觉中的识别受限，而性别分类不受限。当面孔之前在中央视觉中被查看过时，即使这些面孔的姿势、发型和光照条件发生了变化，外周视觉中的识别也会得到改善。针对这种曝光效应背后可能的机制对这些结果进行了讨论。
