Verbal and pictorial elaborations enhance memory in younger and older adults

These studies examined the facilitative role of verbal and pictorial elaborations in younger and older adults' recall of verbal material. During acquisition, subjects studied short sentences under one of several encoding/retrieval conditions where the presence of verbal and pictorial elaborations was systematically varied. Subjects later recalled the target adjectives, given the sentence frames as a prompt. In Experiment 1, explanatory verbal elaborations at study and test enhanced verbal recall for both age groups, but no benefit of pictorial elaborations was observed. In Experiment 2, pictorial elaborations improved recall for both age groups. A significant Age x Encoding Condition interaction effect revealed that the benefit was especially pronounced for the older adults. The implications of these results for understanding the facilitative effects of pictorial illustrations on older adults' recall of verbal material are discussed.
