Coding strategies and imagery differences in memory

概要

Both sentence-generation and imagery-formation are effective coding strategies in learning and memory of verbal materials. However, the problem of which is the more effective, or whether the efficiency of both strategies is the same or not, has not been decided yet. For this problem two theoretical standpoints are possible. One is the semantic elaboration model, and the other is the imagery elaboration model. In previous studies, both models have empirical supports. Here, this problem was examined by introducing the variable of imagery differences. Prior to the experiments, the VVIQ was administered to subjects (160 undergraduates) in order to assess their imagery ability. The main findings were as follows: Imagery-formation is more effective than sentence-generation in memory of verbal materials, the effects of imagery-formation continues longer in good imagers than in poor imagers, and good imagers are apt to voluntarily use imagery in processing input information. These results supported the imagery elaboration model, and this model was refined in order to explain the effects of imagery differences and coding strategies on memory.
