Previous studies indicated that the ability to detect correlations among attributes emerges between 7 and 10 months of age. In the present study, the generality of this developmental transition was examined. Using an infant-control habituation procedure, 48 7- and 10-month-old infants were tested for the perception of correlations among basic facial features. The developmental effects were replicated. Only the 10-month-old infants demonstrated their sensitivity to the pattern of correlation by generalizing to a novel face that preserved the experienced pattern of correlation, while showing increased attention to a face in which the pattern of correlation was violated. 7-month-old infants generalized to both test stimuli containing familiar features, regardless of the status of the correlation. Implications for face perception and the processing of categorical information are discussed.
先前的研究表明，检测属性之间相关性的能力在7至10个月大时出现。在本研究中，对这一发展转变的普遍性进行了检验。采用婴儿对照习惯化程序，对48名7个月和10个月大的婴儿进行了基本面部特征相关性感知测试。重复了发展效应。只有10个月大的婴儿通过推广到保留经验相关性模式的新面孔，同时对相关性模式被违反的面孔表现出更多关注，证明了他们对相关性模式的敏感性。7个月大的婴儿对包含熟悉特征的两种测试刺激都进行了推广，而不管相关性的状态如何。讨论了对面部感知和分类信息处理的影响。
