Aging and inhibitory control in text comprehension.
The degree to which inhibitory regulation is related to the initial perception of information or to the control of response tendencies was examined by asking participants to read paragraphs that included italicized, to-be-ignored words. Older adults were more likely than younger adults to begin vocalization of the italicized words and to make text comprehension errors involving the to-be-ignored information. However, younger adults were subsequently more likely to recognize the words they had apparently ignored, suggesting that inhibitory regulation controls selectivity in response rather than initial perception. Commonalities between inhibitory regulation and source monitoring paradigms are demonstrated, and discussion focuses on the degree to which on-line monitoring of goal-relevant response underlies age-related deficits in both domains.
