Written language comprehension in younger and older adults.

This study examined the effects of text genre and repeated reading on written language comprehension in younger (M = 21 years) and older (M = 72 years) healthy adults (N = 54). Participants verified four text-based statements (i.e., explicit, implicit, contradictory, and elaborated) after reading expository, narrative, and procedural texts. Verification accuracy was comparable for both age groups; however, text genre, statement-type, and repeated reading produced significant effects. Expository passages, explicit and implicit statements, and repeated reading yielded superior results. Procedural passages and contradictory and elaborated statements yielded less accurate results. Statement-types invoked multiple levels of cognitive representation across text genres and age groups. Overall, reading time was significantly faster for younger adults, and reading times were significantly faster for both age groups during the repeated reading trial. Text genre also influenced reading time, with expository passages read faster than narrative and procedural passages. These findings suggest the appreciable influences of text genre and repeated reading on measures of text processing and comprehension in healthy adults, irrespective of age.
