AB The main aim of the present study was to assess whether aging modulatesthe effects of involuntary capture of attention by novel stimuli on performance,and on event-related potentials (ERPs) associated with target processing (N2b andP3b) and subsequent response processes (stimulus-locked Lateralized ReadinessPotential -sLRP- and response-locked Lateralized Readiness Potential -rLRP-). Anauditory-visual distraction-attention task was performed by 77 healthy participants, dividedinto three age groups (Young: 21–29, Middle-aged: 51–64, Old: 65–84 years old).Participants were asked to attend to visual stimuli and to ignore auditory stimuli. Aging wasassociated with slowed reaction times, target stimulus processing in working memory(WM, longer N2b and P3b latencies) and selection and preparation of the motor response(longer sLRP and earlier rLRP onset latencies). In the novel relative to the standardcondition we observed, in the three age groups: (1) a distraction effect, reflected in aslowing of reaction times, of stimuli categorization in WM (longer P3b latency), and ofmotor response selection (longer sLRP onset latency); (2) a facilitation effect on responsepreparation (later rLRP onset latency), and (3) an increase in arousal (larger amplitudesof all ERPs evaluated, except for N2b amplitude in the Old group). A distraction effecton the stimulus evaluation processes (longer N2b latency) were also observed, but only inmiddle-aged and old participants, indicating that the attentional capture slows the stimulusevaluation in WM from early ages (from 50 years onwards, without differences betweenmiddle-age and older adults), but not in young adults
