Previous research examining the impact of training and practice effects on modifying performance of fluid intelligence tasks (Gf) and crystallized intelligence tasks (Gc) were extended to include self-rated performance attributions among non-depressed and depressed older persons. The following general questions were addressed. How does level of depression affect performance on Gf and Gc measures and performance attributions? How does level of depression and degree of benefit from either training or practice relate to changes in attributional styles? The framework used for predicting shifts in attributional styles was the reformulated learned helplessness model. Three hundred twenty-five community-dwelling older persons completed the Gf/Gc Sampler, Beck Depression Inventory, and Attributions for Success/Failure Questionnaire at pretest, posttest (one week), and follow-up (one month). Between the pretest and posttest sessions, subjects participated in one of three experimental conditions; (a) cognitive (induction) training, (b) stress inoculation training, and (c) no-contact control groups. The results from univariate and multivariate analysis of covariance procedures provided partial support for the hypotheses. At pretest, both non-depressed and depressed older persons had internal attributional styles, although based on differential performance outcomes. The depressed persons were found to have more failure experiences as a result of their significantly poorer performance on Gf tasks, versus the non-depressed. Specific Gf training effects were documented regarding attributional shifts for the non-depressed, while there were no changes on their attributional style due to practice on either Gf or Gc tasks. In contrast, only differential practice effects were documented for depressed subjects across Gf and Gc tasks. The importance of assessing personality dimensions in older persons and their xelationship to training and practice effects were discussed, in addition to limitations of the study and suggestions for future research.
