Utilization of Fact Retrieval and Inferential Reasoning in Young, Middle-Aged, and Elderly Adults.
Camp, Cameron J.; Pignatiello, Michael F.
World knowledge is defined as information that is acquired by adults from life experiences. To investigate question answering processes involving world knowledge systems, 120 young, middle-aged and older adults were given questions intended to induce either fact retrieval or inferential reasoning. Multiple-choice and true/false formats were used. The number of correct responses, response time, and subjects' confidence in their responses were recorded. Results showed that the questions elicited appropriate differential cognitive processes for all ages and that both types of cognitive processes were slowed by aging. Older adults, however, were as confident or more confident in their responses than younger adults. The evidence indicates that older adults can accurately and effectively use both fact retrieval and inferential reasoning from world knowledge systems as long as their working memory capacity is not strained.
