Characteristics of visual stimuli and naming performance in aphasic adults.
A confrontation naming task utilizing objects and pictures from the Porch Index of Communicative Ability was presented to 14 aphasic patients. Both initially correct and self-corrected naming responses were compared for the two sets of visual stimuli. In contrast to some studies that have also varied the physical characteristics of size, color and dimensionality, the present study (as well as two other studies) found no significant differences in naming performance for aphasic patients. This evidence would suggest that a choice between pictures and objects will seldom be crucial to diagnosis or therapy with aphasic naming problems.
