The visual dimensions utilized by 11 aphasics in a match-to-sample task to match visual stimuli were investigated to determine if the response patterns differed significantly from those of non-brain-damaged controls (n = 11). There were no significant differences between aphasics and non-aphasics in their selection preference for the dimensions of color, size, orientation, or form. Thus, aphasics and non-aphasics responded similarly with respect to perceptual functioning, nonverbal behavior, and Dale's model (1968) of naming and color perception.
