Abstract

Two experiments examined a new computerized pursuit rotor task that measured psychomotor performance. Exp. 1 examined the acquisition and reliability of performance of 25 adults who performed the task on two sessions separated by a 2-wk. interval. Exp. 2 was a placebo-controlled test of task sensitivity to the performance-impairing effects of a 0.65 g/kg dose of alcohol. Exp. 1 showed that participants' performance was reliable over time. Exp. 2 showed that alcohol-impaired performance compared with placebo. The task could be useful for evaluating performance-impairing effects of other CNS depressant drugs, as well as complementing assessment batteries for research and instruction in studies of motor learning and human performance.
