摘要

A categorical perception (CP) effect is said to occur when performances in between-category discriminations are better than equally spaced within-category discriminations (Hamad, 1987). Evidence for CP effects is often obtained in successive as opposed to simultaneous discrimination tasks, and for emulated Munsell colour samples whose spacing might not correspond to equal discriminability between stimuli. These two questions were addressed, firstly by investigating CP effects in both a simultaneous and a delayed match-to-sample task, and secondly by using reaction times (RTs) in the simultaneous presentation task to derive an inter-stimuli discriminability space for two observers. CP effects as revealed by faster RTs in the cross-category condition were observed in the delayed but not in the simultaneous match-to-sample task. Distances in the u'v' diagram did not accurately predict discriminative RTs for supra-threshold colour samples, and the inter-stimuli discriminability spaces derived for our two observers differed.
