| Abstract: | Berlin and Kay's notion of basicness was defined by a combination of linguistic and psychological criteria, but they suggested that the psychological criteria might be extended. The experiments reported here were designed to explore a possible extension by searching for perceptual effects of basicness. Russian speakers who have two basic terms for the blue region of colour space were compared with English speakers who have only one basic term for the same region on two perceptual tasks. The first two experiments sought for greater Stroop interference for the Russians than for the English for the critical “blue” stimuli, and the third experiment sought greater perceptual differentiation for the Russians in the blue region. All experiments clearly replicated standard findings, but all singularly failed to find the predicted differences between the two groups. It is argued that whilst the results are consistent with there being no psychological effect of basicness, it is necessary to search for possible effects in other domains, such as recognition memory, before accepting this conclusion. |
