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 the 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.

Confrontation naming impairment in dementia

The effects of dementia etiology and severity on the confrontation naming ability of individuals with Alzheimer's, Huntington's, and Parkinson's diseases and multi-infarct dementia are investigated. Although naming impairment is reported as a consequence of dementing illness, confrontation naming is not found to be significantly impaired in mildly involved patients. Further, although moderate Huntington's and Parkinson's patients made more naming errors than normals, only moderate Alzheimer's disease patients are found to be significantly different. Regardless of etiology, most misnamings are found to be semantically related or semantically and visually related to the stimulus. Results challenge the theory that misnamings of dementia patients result primarily from misperception.
