چکیده
Language affects perception. But how? Recent findings (Boutonnet & Lupyan, 2015; Bocanegra, Poletiek & Zwaan, submitted) suggest a dissociation between perception that is mediated as compared to not mediated by language. One explanation is that language –that is combinatorial in naturestresses the separate features of objects. We investigated the effect of combinatorial (two words) and non-combinatorial (one word) labels on the perceptual separation of features in visual recognition. Participants were trained to categorize meaningless objects with two dimensions: shape and height. Each category had either a one word name; or a two words name reflecting its features. Participants then were tested on new objects . Combinatorial labels enhanced categorization performance as compared to single labels. This suggests that language, by decomposing objects into parts, might drive dimension separation in vision as well.
