Résumé
Comparison mechanisms have been implicated in the development of abstract, relational thought,
including object categorization. D. Gentner and L. L. Namy (1 999) found that comparing 2 perceptually
similar category members yielded taxonomic categorization, hhereas viewing a single member of the
target category elicited shallower perceptual responding. The present experiments tested 2 predictions
that follow from Gentner and Namy’s (1999) model: (a) Comparison facilitates categorization only when
the targets to be compared share relational commonalities, and (b) providing common labels for targets
invites comparison, whereas providing conflicting labels deters it. Four-year-olds participated in a
forced-choice task. They viewed 2 perceptually similar target objects and were asked to “find another
one.” Results suggest an important role for comparison in lexical and conceptual development.
