The effect of stimulus color on naming performance of aphasic adults.

The purpose of this study was to investigate the potential effect that color in visual stimuli may have on the confrontation naming ability of aphasic patients. A group of 11 nonfluent and fluent aphasic adults were administered identical black and white and colored versions of a naming test. Administration procedure for the tests required that a phonemic cue be given in the event of an incorrect response. The results revealed that the presence of color in the visual stimuli did not result in significantly improved naming performance in either group of subjects. Only the addition of the phonemic cue resulted in improved naming performance for both the nonfluent and fluent aphasic subjects. Further, no additional benefit was seen when color and cue were simultaneously presented.
