Depth of Processing and Text Recall in Adulthood

Abstract

The depth of processing model suggests that incidental learning occurs at various “depths” corresponding to the degree of semantic analysis. Because deep processing is associated with improved recall, and because older adults generally perform at a lower level than younger adults, this model has been applied to aging research. The present study examined the validity of this model by comparing a sample of three German adult age groups with a similar sample in an earlier American study. Specifically, subjects read a 500-word narrative under one of four conditions: (a) a shallow, nonsemantic orienting task; (b) and (c) two deep, semantic orienting tasks; or (d) an intentional condition. Results indicated that, overall, younger adults performed better than older adults, that recall in the intentional condition was significantly better than in the two deep processing conditions, and recall in these conditions was better than in the shallow condition. Cross-sample comparisons and subsequent implications for the validity of the model are discussed.
