Effects of description modes in the acquisition and transfer of a second-order conditional discrimination in human adults
Main Article Content
Abstract
Twenty college students served as subjects to evaluate the effects of different modes of describing performance on the acquisition, transfer and maintenance of a conditional discrimination. A second-order matching-to-sample task was used. A11 subjects were exposed to a pre-test, a first training phase on similarity and difference matching-to-sample, two intramodal and extramodal transfer tests and a post-test. In a second training phase, subjects were assigned to five different conditions: a control condition similar to the first training phase, and four ways of presenting descriptions after performance in every training trial. The descriptions modes were to read a text, to copy a text, to complete a text, or lo read a text and to recognize it by choice. Results of this study showed that a11 the subjects that read, copied or recognized by choice the descriptions, achieved 90% or more correct responses in the post-test, the second training phase and transfer test. Outcomes are discussed in terms of the effectiveness of the modes of presenting descriptions and new experiments are suggested.
