我们研究了社区面部经验在6个月和8个月大的白人婴儿对自己和其他种族的面部扫描中的作用。我们测量了婴儿的比例注视时间和扫描路径振幅作为面部加工的指标。在种族同质的群体中，婴儿对信息丰富的面部区域的注视时间比例随年龄和面部种族的变化而变化，而在种族不同的群体中，婴儿的扫描路径振幅随年龄和面部种族的变化而变化。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有不同的反应。然而，来自两个社区的8个月大的婴儿显示出不同的跨种族面部扫描模式。因此，家庭以外的社区经历似乎有助于6至8个月大的婴儿对自己和其他种族面孔的差异扫描的发展。
Weexamined 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.
