Does the incongruent verbal label produce the inversed categorical perception of colour?
” Perception 36 ECVP Abstract Supplement Does the incongruent verbal label produce the inversed categorical perception of colour? T Suegami, C Michimata Previous studies (Roberson and Davidoff, 2000 Memory and Cognition 28 977 – 986; Suegami and Michimata, 2006 paper presented at the 4th Asian Conference on Vision in Shimene) suggested that categorical perception (CP) of colour would be mediated by a verbal label. On the basis of those studies, we hypothesize that the discrimination of the within-category pair that has different verbal labels would be more accurate than the discrimination of the between-category pair that has the same verbal label (inversed CP). In the experiment, we employed a simultaneous 2AFC colour-matching task. A colour word was presented before the stimulus. If the word was incongruent with the colour stimulus, the word would produce an incongruent verbal label. The results showed that an incongruent word eliminated the CP but did not produce the inversed CP. Ho
