The hue spectrum is a continuum of light, yet we perceive it categorically. The categories used to describe this continuum vary across the world’s languages and there are marked differences in the numbers of colour categories and the locations of category boundaries. For example, the green–blue… read more

This study aimed to establish the basic colour terms of Arabic and to clarify the status of three Arabic terms for blue: azrock, samawee and khuhlie. Data from a list task were collected from 253 child and 200 adult native Arabic speakers. The patterns of the terms ordered by their frequency from… read more

Davies 2011 Investigating the underlying mechanisms of categorical perception of colour using the event-related potential technique New Directions in Colour Studies, Biggam, Carole P., Carole Hough, Christian Kay and David R. Simmons (eds.), pp. 237–250 | Article

Categorical perception (CP) of colour is demonstrated by faster and more accurate discrimination of colours that cross a category boundary than equivalently spaced colours from the same colour category. Despite a plethora of behavioural research investigating the origin and nature of colour CP, the… read more

Davies 2011 Category training affects colour discrimination but only in the right visual field New Directions in Colour Studies, Biggam, Carole P., Carole Hough, Christian Kay and David R. Simmons (eds.), pp. 251–264 | Article

There is indirect evidence that categorical colour perception (better discrimination of colours from different categories than those from the same category). For instance, CP can be induced across a newly learned category boundary (Özgen & Davies 2002). Here we replicate and extend Özgen and… read more

Lillo, Julio, Humberto Moreira and Ian R.L. Davies 2011 Red-Green dichromats’ use of basic  colour terms New Directions in Colour Studies, Biggam, Carole P., Carole Hough, Christian Kay and David R. Simmons (eds.), pp. 293–308 | Article

We describe Red-Green dichromats’ use of basic colour terms and compare this with naming errors predicted by metameric equivalence derived from confusion lines in CIE (International Commission on Illumination) coordinates. After briefly reviewing previous work, the results from two tasks –… read more

Perceptual learning has been shown on a wide variety of achromatic visual tasks. However, very little work has explored the possibility of improvements on chromatically based tasks. Here, we used a transfer of learning paradigm to assess the specificity of improvements at discriminating the… read more

Corbett, Greville G. and Ian R.L. Davies 1995 Linguistic and Behavioural Measures for Ranking Basic Colour Terms Studies in Language 19:2, pp. 301–357 | Article

We report an attempt to find more objective measures for identifying basic colour terms. We investigate the types of measure available, both linguistic and behavioural, and the statistical techniques for establishing the closeness of fit with the predictions derived from Berlin and Kay. This leads… read more
