â¢We explored how visual expertise for print changes with age.â¢Behavioral and electrophysiological data (P100, N170, alpha power) were recorded.â¢Visual expertise for print is preserved with age.â¢A decrease in stimulus processing speed was observed as a function of age.
Progressive visual processing decline is a known factor in aging. The present study investigates the evolution of visual expertise for printed stimuli with aging. Fifty-five participants of increasing age (20-30, 40-50, 60-70, 75-85Â years old) were recruited. Behavioral and EEG data were collected during a lexical decision task, in which words and symbol strings were presented. Analyses of EEG data focused mainly on three major points: visual expertise for print, automatization of the expertise and differences in attentional demand between the processing of words and symbols. Results indicated a preservation of visual expertise with age, with larger N170 amplitude for words than for symbols. Moreover, a decrease in stimulus processing speed was observed as a function of age. No difference in attentional demand as a function of stimulus was observed.
