和面孔一样，身体也是社会信息的重要来源。然而，研究表明，婴儿不会发展身体表征（即，关于典型人体的知识）直到生命的第二年，尽管他们对面部信息的敏感性要早得多。然而，以前的研究只考察了婴儿是否对身体部位的典型排列敏感。我们研究了年龄较小的婴儿是否有不同类型的身体知识，即身体部位的相对大小。研究人员对5个月和9个月大的婴儿进行了测试，以确定他们对正常身体和比例扭曲身体的偏好。9个月奥尔兹在图像被直立呈现时表现出对正常身体的偏好，而在图像被倒置时则没有。五个月奥尔兹的婴儿在这两种情况下都没有表现出偏好。这些结果表明，婴儿在一岁后半期就具备了有关人体的知识。此外，考虑到直立刺激比倒置刺激更好的表现与专业知识有关，年龄较大的婴儿表现出身体意象的倒置效应这一事实表明，至少在9个月大时，身体处理的专业知识水平已经发展。
Like faces, bodies are significant sources of social information. However, research suggests that infants do not develop body representation (i.e., knowledge about typical human bodies) until the second year of life, although they are sensitive to facial information much earlier. Yet, previous research only examined whether infants are sensitive to the typical arrangement of body parts. We examined whether younger infants have body knowledge of a different kind, namely the relative size of body parts. Five- and 9-month-old infants were tested for their preference between a normal versus a proportionally distorted body. Nine-month-olds exhibited a preference for the normal body when images were presented upright but not when they were inverted. Five-month-olds failed to exhibit a preference in either condition. These results indicate that infants have knowledge about human bodies by the second half of the first year of life. Moreover, given that better performance on upright than on inverted stimuli has been tied to expertise, the fact that older infants exhibited an inversion effect with body images indicates that at least some level of expertise in body processing develops by 9 months of age.
