Adults are experts at processing faces, in that they quickly and effortlessly decipher information from faces during social interactions. However, a hallmark of face expertise in adulthood is that it is confined to those face categories with which adults have had the most experience. The result is a diminished ability to discriminate and recognize individuals belonging to less familiar face categories (e.g., faces of other species, other races, and other ages). This property of adult face perception has its origins in infancy. Therefore, it has been postulated that experience with a particular face category must occur early in life, or expertise with that face category will never be attained. However, no one has yet investigated the full extent of plasticity in the adult face processing system. The proposed program of research will fill this gap in the literature by uncovering how the perception of other-race faces changes as adults gain increasing amounts of experience with this unfamiliar face category.

成年人是处理面孔的专家，因为他们在社交互动中快速而毫不费力地从面孔中破译信息。然而，成年人的面部专业知识的一个特点是，它仅限于那些成年人有最多经验的面部类别。结果是辨别和识别属于不太熟悉的面部类别（例如，其他物种，其他种族和其他年龄的面孔）。成年人对面部的感知起源于婴儿时期。因此，人们假设，对特定面孔类别的经验必须发生在生命的早期，否则永远无法获得对该面孔类别的专业知识。然而，还没有人研究过成人面孔加工系统的可塑性。拟议的研究计划将填补这一空白，在文献中揭示如何感知其他种族的面孔变化，作为成年人获得越来越多的经验，这一不熟悉的面孔类别。
