Abstract
The present study investigated discourse processing in young, aged—normal, and aged—memory impaired individuals using materials which were of both general and aged—cohort specific interest. The results of free recall and recognition tasks indicated that reliable quantitative and qualitative differences distinguished the performance of the three groups. Application of the Kintsch and van Dijk model ( W. Kintsch & T. A. van Dijk. Toward a model of text comprehension and production. Psychological Review, 1978 , Vol. 85, pp. 363–394.) text processing both supported and enlarged upon this conclusion. the results are interpreted in terms of hypothetical age-related and pathology-related differences in the capacity of working memory and also in the selection process for storage of information in working memory. Lastly, the present application of cognitive science to one particular problem domain (life-span differences in the processing of discourse) is suggested as a model for exploring other applied issues.
