We examined the role of community face experience on 6- and 8-month-old Caucasian infants' scanning of own- and other-race face scanning. We measured infants' proportional fixation time and scan path amplitudes as indices of face processing. Proportional fixation time to informationally rich face regions varied as a function of age and face race for infants living in a racially homogeneous community, whereas scan path amplitudes varied as a function of age and face race for infants living in a racially diverse community. In both communities 6-month-old infants did not show different responding to own- and other-race faces, whereas 8-month-old infants responded differently to own- and other-race faces. However, 8-month-old infants from the two communities showed different patterns of cross-race face scanning. Therefore, experience in the community beyond the home appears to contribute to the development of differential scanning of own- versus other-race faces between 6 and 8 months of age.
我们研究了社区面孔体验对6个月和8个月大的白人婴儿对自己种族和其他种族面孔扫描的作用。我们测量了婴儿的比例注视时间和扫描路径幅度，作为面孔加工的指标。对于生活在种族单一社区的婴儿，对信息丰富的面部区域的比例注视时间随年龄和面孔种族而变化，而对于生活在种族多样化社区的婴儿，扫描路径幅度随年龄和面孔种族而变化。在这两个社区中，6个月大的婴儿对自己种族和其他种族的面孔没有表现出不同的反应，而8个月大的婴儿对自己种族和其他种族的面孔反应不同。然而，来自两个社区的8个月大婴儿表现出不同的跨种族面孔扫描模式。因此，家庭之外的社区体验似乎有助于6至8个月大婴儿对自己种族与其他种族面孔进行差异扫描的发展。
