A comparison of chromatic and achromatic versions of the Stroop color-word test

Abstract

Achromatic and chromatic versions of the color-word test were given to 25 Ss. When the patches were rectangles, achromatic shades were named slightly faster than colors. With interference to naming from the use of incongruent names as stimuli, achromatic shades were named much faster than colors. Interference from incongruent names thus appears to amplify processing time differences and may prove useful for temporal analysis of the visual processing of hue, luminance, and saturation. Extensions of the Stroop test to other perceptual attributes should allow similar analyses of these attributes. © 1971, The Psychonomic Society, Inc.. All rights reserved.
