Age-Related Differences in Memory as a Function of Imagery Processing

The effects of aging on imagery production and use-following the learning of concrete and abstract words-and their relations to subsequent memory performance were explored in 2 experiments. Both experiments demonstrated better free recall of concrete than of abstract words (the concreteness effect). Experiment 1 showed this superiority to be greater for young subjects only under explicit imagery instructions. Experiment 2 revealed that the advantage of concrete over abstract words reflects the use of differential imagery production. The results are discussed in terms of age differences in imagery utilization and the effects of visual processing on recall.
