不同概念范畴和特征类别对儿童归纳推理多样性效应的影响

为探讨概念范畴和特征类别对归纳推理多样性效应的影响, 采用2(概念范畴: 生物类别与非生物类别)´2(特征类别: 不可见的隐蔽特征和可见的外显特征)的实验设计, 设计了四组任务来考察5~6岁、8~9岁儿童归纳推理多样性效应的表现水平。结果显示: 在非生物类别范畴材料上, 5~6岁儿童在两种特征类别上均未表现出多样性效应, 8~9岁儿童在隐蔽特征类别上表现出多样性效应; 在生物类别材料上, 5~6岁、8~9岁儿童在外显特征和隐蔽特征上均未表现出多样性效应。概念范畴和特征类别对8~9岁儿童的归纳判断力有显著影响: 在概念范畴上, 儿童在非生物范畴材料上的表现显著高于生物范畴; 在特征类别上, 儿童在隐蔽特征上的表现高于外显特征。

The Interaction Effect of Conceptual Category and Property Category on Diversity Effects of Reasoning on Children

Positive diversity effects among adults have been reported in a number of studies using a variety of methods (e.g.,Heit,2000;Kim,Keil,2003;Osherson,Smith,Wilkie et al.,1990;Lopez,1995;Sloman,1993).However,there has been considerable debate about whether children also prefer diverse samples as the basis for induction.Several initial developmental studies,in which children were asked to make inductive inferences about animal categories based on a limited set of examples,suggested that children before 9 years ...
