类别成员之间的差异性如何影响婴儿的类别学习？我们探讨的顺序，不同的项目被抽样类别形成的影响。两组10个月大的婴儿被提出了一系列的例子被组织成一个单一的类别。在低距离组中，呈现顺序最小化了连续样本之间的感知距离。在一个高距离组中，呈现顺序最大化了连续样本之间的距离。在测试中，只有在高距离条件下的婴儿可靠区分类别原型和非典型样本。因此，婴儿学习样本的顺序影响了他们的分类表现。我们的研究结果表明，在婴儿的类别学习过程中的相似性的时刻到时刻的变化的重要性。(C)2011 Elsevier B.V.保留所有权利。
How does variability between members of a category influence infants' category learning? We explore the impact of the order in which different items are sampled on category formation. Two groups of 10-months-olds were presented with a series of exemplars to be organized into a single category. In a low distance group, the order of presentation minimized the perceptual distance between consecutive exemplars. In a high distance group, the order of presentation maximized the distance between successive exemplars. At test, only infants in the High Distance condition reliably discriminated between the category prototype and an atypical exemplar. Hence, the order in which infants learnt about the exemplars impacted their categorization performance. Our findings demonstrate the importance of moment-to-moment variations in similarity during infants' category learning. (C) 2011 Elsevier B.V. All rights reserved.
