Abstract:
23 patients with idiopathic Parkinson's disease (PD) and 22 healthy control subjects participated in an experimental investigation of learned helplessness and illusion-of-control phenomena. Subjects were divided into depressed and non-depressed groups according to scores on the Beck Depression Inventory. Each completed four problems associated with an instrumental learning task in which they judged the degree of control their responses exerted over repeated green-light onset. Degree of contingency varied from 0% to 75% and subjects utilized both verbal and motor response modes. Subjects also estimated frequency of green light onsets for each problem. Contrary to expectation, PD subjects did not differ from relevant comparison groups in their contingency or frequency estimates. Tests of the prediction that depressed subjects' contingency ratings would be more accurate than non-depressives' approached significance (p < .064), although the pattern of mean differences was not consistent with an illusion-of-control interpretation.
