基于轮廓信息可以被成人用来形成基本的分类表征的证据，采用熟悉-新奇偏好程序进行了4个实验，研究了3个月和4个月的婴儿是否可以形成分类表征；从轮廓（例如，整体形状和外部轮廓）中获得的感知信息对猫和狗的分类表征。实验1和2表明，婴儿可以对猫和慢跑的轮廓形成个性化的分类表征，而实验3和4表明，婴儿可以使用来自头部而不是身体的轮廓信息来分类区分这两个物种。这些结果表明，以头部为中心的一般形状或外部轮廓信息足以使幼儿形成对猫和狗的个性化分类表征。因此，这些数据提供了关于感知信息的本质的信息，这些信息可以被婴儿用来形成单个动物物种的类别表征，并根据一般领域与特定领域的处理帐户进行讨论。(C) 2001学术出版社。
Given evidence that silhouette information can be used by adults to form categorical representations at the basic level, Four experiments utilizing the familiarization-novelty preference procedure were performed to examine whether 3- and 4-month-old infants could form ;categorical representations for cats versus dogs from the perceptual information available in silhouettes (e.g., global shape and external outline). Experiments 1 and 2 showed that infants could form individuated categorical representations for cat and Jog silhouettes, whereas Experiments 3 and 4 revealed that infants could use silhouette information from the head, but not the body, to categorically separate the two species. These results indicate that general shape or external contour information that is centered about the head is sufficient for young infants to form individuated categorical representations for cats and dogs. The data thus provide information regarding the nature of the perceptual information that can be used by infants to form category representations for individual animal species and are discussed in terms of domain-general versus domain-specific processing accounts.
