现在普遍的共识是，婴儿可以使用几种不同的视觉特性作为分类的基础。尽管如此，关于婴儿何时以及是否可以通过上下文信息从他们可用的属性中选择相关属性，人们知之甚少。我们在这里表明，到10个月大时，通过观察性学习，婴儿可能会偏向于使用两种对象属性中的一种或另一种进行分类。两组婴儿观看了一位女演员根据形状(形状组)或表面图案(图案组)对物体进行分类。当随后呈现两个与分类规则中的一个或另一个相抵触的测试试验时，两组中的婴儿看分类事件的时间较长，该分类事件与该组所熟悉的规则不一致。这些结果是参考婴儿期选择性特征加工的发展而讨论的。(C)2007 Elsevier Inc.保留所有权利。
There is now general consensus that infants can use several different visual properties as the basis for categorization. Nonetheless, little is known about when and whether infants can be guided by contextual information to select the relevant properties from amongst those available to them. We show here that by 10 months of age infants can be biased, through observational learning, to use one or the other of two object properties for classification. Two groups of infants watched an actress classifying objects by either shape (the Shape group) or surface pattern (the Pattern group). When subsequently presented with two test trials which contradicted either one or the other of the classification rules, infants in the two groups looked longer to the classification event that was incompatible with the rule that group had been familiarized to. These results are discussed with reference to the development of selective feature processing in infancy. (C) 2007 Elsevier Inc. All rights reserved.
