Orienting attention to visual stimuli was studied in 13 patients with Parkinson's disease whose responses were compared to those of a matched control group using a cued reaction-time task which measured cost and benefit effects of orienting of attention. Both groups were screened to exclude dementia, psychiatric disease, and other neurological abnormalities. Although Parkinson patients showed overall slow mean reaction time, responses showed a pattern of cost and benefit effects similar to that of the control group. The results suggested that Parkinson patients are not impaired on visuospatial orienting of attention on this task.
