众所周知，在视觉单词识别中存在眼睛注视的优选着陆位置。然而，在人脸识别中存在的首选着陆位置是不太确定的。也不知道需要多少注视才能识别一张脸。为了研究这些问题，我们记录了人脸识别过程中的眼球运动。在其他标准的面部识别任务中，受试者在掩蔽刺激之前允许可变数量的注视。我们发现，最佳的识别性能实现了两个固定，性能并没有提高额外的固定。第一注视点的分布在鼻子中心的左侧，第二注视点的分布在鼻子中心周围。因此，这些似乎是面部识别的首选着陆位置。此外，在面部学习过程中所作的固定在不同的位置，从那些在面部识别，也更可变的持续时间;这表明，不同的策略用于面部学习和面部识别。
It is well known that there exist preferred landing positions for eye fixations in visual word recognition. However, the existence of preferred landing positions in face recognition is less well established. It is also unknown how many fixations are required to recognize a face. To investigate these questions, we recorded eye movements during face recognition. During an otherwise standard face-recognition task, subjects were allowed a variable number of fixations before the stimulus was masked. We found that optimal recognition performance is achieved with two fixations; performance does not improve with additional fixations. The distribution of the first fixation is just to the left of the center of the nose, and that of the second fixation is around the center of the nose. Thus, these appear to be the preferred landing positions for face recognition. Furthermore, the fixations made during face learning differ in location from those made during face recognition and are also more variable in duration; this suggests that different strategies are used for face learning and face recognition.
