Abstract

We investigated how the benefits of comparisons (within- and/or between- category comparisons) for generalizing novel names for novel objects along a non-salient dimension (texture) might depend on dimensional distinctiveness. We tested 4- and 6-year-olds. We found that in the case of a lower distinctiveness, older children gave more texture-based answers following within-category comparison whereas younger children gave more texture-based answers in between-category comparisons. When distinctiveness was high, both groups benefited from within-comparison. They also benefited from between-category comparison only when within-category comparison were available (i.e. when both kinds of comparison were available). We interpret these findings in terms of differential costs of comparison for varying levels of distinctiveness along either nonsalient or salient dimensions.
