In comparison to younger adults, older adults demonstrate deficiencies in cognitive and linguistic abilities. Such cognitive factors that decline with age include working memory capacity and inhibitory abilities. The purpose of the present investigation was to measure differences in time course processing of inference revision abilities, as well as working memory, as they exist relative to adult age differences. Fifteen neurologically intact older adults and 15 younger adults participated in this study. A cross-modal lexical priming, paradigm wits chosen as the measure of the inference revision task, the listening span task of Tompkins, Bloise, Timko, and Baumgaertner ( 1994) was selected as the measure of working memory. Both groups demonstrated normal priming effects. No age-related differences were found on the working memory measure. Age-related differences did emerge on inferencing abilities. A significant correlation emerged between the older group's performance oil comprehending inference revisions and their working memory capacity. Generally inhibitory abilities and working memory capacity appeared to adversely affect older participant's performance. (C) 2002 Elsevier Science (USA).
