Annotation	The performance of seven Parkinson's disease patients on a discrete pursuit tracking task was studied under alleviated (medicated) and unalleviated (non-medicated) conditions, and compared with the performance of seven non-Parkinson subjects matched for age and gender. All subjects completed 2,000 responses on the tracking task, which provided variations in directional probability and the distance to be moved. Overall, results suggested that once given sufficient practice to learn a novel task, and when under drug control, Parkinson patients were not significantly different from the age-matched controls. Two exceptions where Parkinson patients evidenced slower responses were noted: their ability to make decisions when movement direction was less predictable; and when they had to readjust their motor responses after an unexpected movement error.
