Abstract
Two groups of endogenous and reactive unipolar depressives were compared with two nondepressed groups, psychiatric patients and normal controls, on skill and chance task expectancy changes, psychomotor retardation measures, the Rotter externality, the Buss-Durkee Hostility, and the Eysenck Personality Questionnaire scores. There were no differences between the groups on the expectancy changes on skill task. This finding is not consistent with Seligman's learned helplessness theory of depression. Depressed patients scored more poorly on psychomotor speed tests. The scores on these tests were correlated with the ratings of the aspired-to performance, which is consistent with Beck's cognitive theory of depression.
