Resumo(s)
Previous research has found that category representations are highly malleable knowledge structures, varying
widely across different contexts and individuals. However, it has also been found that such malleability does not
apply equally to all types of category information. The present research further investigates the representational
malleability versus stability of natural taxonomic categories. Using perceptual fluency as means to induce
malleability, we explored whether malleability is moderated by the degree of typicality of category information.
In the first experiment, we found that fluency-based malleability only occurs for non-typical category information. In follow-up experiments, we investigated the boundary conditions under which such fluency-based
malleability occurs. Namely, in Experiment 2, we showed that the effect of fluency on non-typical features
disappeared when there is a sensory modality mismatch between study and test phases. Finally, in Experiment 3,
we demonstrated that this effect reappears in the modality mismatch condition when participants are given a
response deadline. The implications of these findings to current theories of category representation and the
perceptual fluency literature are discussed.
