Learning and Retention of Concepts Formed from Unfamiliar Visual Patterns. Final Report.
Lantz, Alma E.
Two experiments were conducted to investigate the learning and retention of concepts formed from novel visual stimulus materials (wave-form patterns). The purpose of the first experiment was to scale sets of wave forms as a function of difficulty, i.e., subjects were shown a prototype wave form and were asked to give same-different judgments for subsequent wave forms. On the basis of these results, sets of "simple" and "difficult" instances of concepts were chosen. In the second experiment, subjects learned four wave-form concepts with either simple or difficult instances over a four-day period and were tested for retention after periods of 1, 3, and 10 days. The data showed significantly better performance for simple concepts, but neither group showed any performance decrement measured by the percentage of correct identifications over any of the three retention intervals. Both groups did, however, display longer decision reaction times during the retention testing. It was suggested that the results indicated a longer retrieval route for the correct responses after the passage of time. (Author/SW)
