| Abstract: | Three experiments examined the effects of aging on comprehension of spoken language. Integrative and constructive aspects of comprehension showed much more marked age-related deficits than registration of surface meaning. Experiment 1 showed that old subjects had difficulty in making inferences based on presented facts. Experiment 2 revealed a similar deficit in old people's ability to detect anomalies in newly presented information by reference to prior everyday knowledge. And Experiment 3, which tested story recall, showed that old subjects were less well able to extract and retain gist information than younger subjects. These difficulties are interpreted as reflecting a limitation in processing capacity such that the demands of concurrently registering surface meaning and simultaneously carrying out integrative and constructive processes exceed capacity in old age. |
