Abstract

Eye gaze is an important tool for social contact. In this study, we investigated whether direct gaze facilitates the recognition of three-dimensional face images in infants. We presented artificially produced face images in rotation to 6-8 month-old infants. The eye gaze of the face images was either direct or averted. Sixty-one sequential images of each face were created by rotating the vertical axis of the face from frontal view to ± 30°. The recognition performances of the infants were then compared between faces with direct gaze and faces with averted gaze. Infants showed evidence that they were able to discriminate the novel from familiarized face by 8 months of age and only when gaze is direct. These results suggest that gaze direction may affect three-dimensional face recognition in infants.

摘要

目光注视是社交接触的重要工具。在本研究中，我们调查了直接注视是否有助于婴儿识别三维面部图像。我们将人工制作的面部图像旋转展示给6至8个月大的婴儿。面部图像的目光注视方向要么是直接的，要么是回避的。通过将面部垂直轴从正视图旋转到±30°，为每张脸创建了61张连续图像。然后比较了婴儿对直接注视的面部和回避注视的面部的识别表现。婴儿表现出证据表明，他们到8个月大时，且只有在注视是直接的情况下，才能够区分新面孔和熟悉的面孔。这些结果表明，注视方向可能会影响婴儿对三维面部的识别。
