Inductive Inferences across Time and Identity: Are Category Members More Alike than Single Individuals?
Lawson, Christopher A.; Kalish, Charles W.
Journal of Cognition and Development, v7 n2 p233-252 Apr 2006
Young children tend to expect that 2 members of the same category will share properties, yet they frequently deny that an individual's properties will remain stable across time and context. Two experiments, involving 72 four- to five-year-olds, 72 seven- to eight-year-olds, and 76 undergraduates, explored the factors that lead children to generalize properties across and within individuals. Results suggest that adults' and older children's judgments are consistent with the principle of homogeneity--within-individual projections are more secure than across. In contrast, young children showed distinct patterns of reasoning across and within individuals, suggesting that for young children, the 2 contexts may present distinct inductive problems. This discussion focuses on how features of each problem contribute to young children's willingness to make inductive generalizations. (Contains 2 figures, 1 footnote and 1 table.)
