THE ROLE OF PRINT EXPOSURE IN SUPPORTING COGNITIVE ABILITY AMONG OLDER ADULTS

Abstract

Reading is an activity that has long been thought to have beneficial effects on cognitive ability, however, little is known about the effects of long-term reading engagement on cognition among older adults. Pre-test data are reported from an ongoing study of the effects of a literacy-based intervention on cognition among older adults. Participants (66.7% female) ranging from 60 to 79 years of age with education ranging from 11 to 19 years were administered a battery of measures, including print exposure checklists, which are objective indices for assessing long-term reading-related activities, as well as cognitive assessments. A composite measure of print exposure was based on the Author Recognition Test, Magazine Recognition Test, Non-fiction Author Recognition Test, and Fiction Recognition Test (alpha=.92). Cognition was assessed in a comprehensive battery, including measures of verbal ability, working memory, episodic memory, and verbal fluency (alpha=.83). Print exposure was marginally related to self-reported time spent reading (r=.27, p.4), suggesting criterion-related validity. Age-related declines were not evident for any of our cognitive measures in this sample, t(46)’s.8, and there was a modest increase in reading engagement with age (r=.36, p=.01). Controlling for verbal ability, print exposure had a significant positive influence on global cognition (standardized beta=0.38, p=.01); however, these effects were specific to episodic memory and verbal fluency, t(46)>2, p<.05. These preliminary findings are suggestive of selective cognitive benefits from continued literacy engagement in reading in later life.
