词语如何影响分类？根据一些说法，即使在发展的早期，词也是类别标记，与其他特征不同。根据其他说法，在开发早期，单词是输入的一部分，与其他功能类似。目前的研究探讨了这个问题，通过检查的作用，在8至12个月大的婴儿类别学习的单词和动态视觉特征。婴儿熟悉的例子，从一个类别的标签定义或运动定义的条件，然后测试与原型的研究类别，从一个新的对比类别。眼动实验结果表明，在运动定义条件下，幼儿的类别学习能力优于标签定义条件，在动态视觉特征条件下，幼儿的注意力更倾向于分散在不同的视觉特征上。这些结果提供了一点证据的想法，语言标签的类别标记，促进类别学习。(C)2015 Elsevier Inc.

How do words affect categorization? According to some accounts, even early in development words are category markers and are different from other features. According to other accounts, early in development words are part of the input and are akin to other features. The current study addressed this issue by examining the role of words and dynamic visual features in category learning in 8- to 12-month-old infants. Infants were familiarized with exemplars from one category in a label-defined or motion-defined condition and then tested with prototypes from the studied category and from a novel contrast category. Eye-tracking results indicated that infants exhibited better category learning in the motion-defined condition than in the label-defined condition, and their attention was more distributed among different features when there was a dynamic visual feature compared with the label-defined condition. These results provide little evidence for the idea that linguistic labels are category markers that facilitate category learning. (C) 2015 Elsevier Inc. All rights reserved.
