RT Journal Article T1 Involuntary capture and voluntary reorienting of attention decline in middle-aged and old participants A1 Correa Jaraba, Kenia Shaily A1 Cid Fernández, Susana A1 Lindín Novo, Mónica A1 Díaz Fernández, Fernando K1 Involuntary attention K1 Aging K1 Mismatch Negativity (MMN) K1 P3a K1 Reorienting Negativity (RON) AB The main aim of this study was to examine the effects of aging on event-related brainpotentials (ERPs) associated with the automatic detection of unattended infrequentdeviant and novel auditory stimuli (Mismatch Negativity, MMN) and with the orienting tothese stimuli (P3a component), as well as the effects on ERPs associated with reorientingto relevant visual stimuli (Reorienting Negativity, RON). Participants were divided into threeage groups: (1) Young: 21–29 years old; (2) Middle-aged: 51–64 years old; and (3) Old:65–84 years old. They performed an auditory-visual distraction-attention task in whichthey were asked to attend to visual stimuli (Go, NoGo) and to ignore auditory stimuli (S:standard, D: deviant, N: novel). Reaction times (RTs) to Go visual stimuli were longerin old and middle-aged than in young participants. In addition, in all three age groups,longer RTs were found when Go visual stimuli were preceded by novel relative to deviantand standard auditory stimuli, indicating a distraction effect provoked by novel stimuli.ERP components were identified in the Novel minus Standard (N-S) and Deviant minusStandard (D-S) difference waveforms. In the N-S condition, MMN latency was significantlylonger in middle-aged and old participants than in young participants, indicating aslowing of automatic detection of changes. The following results were observed in bothdifference waveforms: (1) the P3a component comprised two consecutive phases in allthree age groups—an early-P3a (e-P3a) that may reflect the orienting response towardthe irrelevant stimulation and a late-P3a (l-P3a) that may be a correlate of subsequentevaluation of the infrequent unexpected novel or deviant stimuli; (2) the e-P3a, l-P3a, andRON latencies were significantly longer in the Middle-aged and Old groups than in theYoung group, indicating delay in the orienting response to and the subsequent evaluationof unattended auditory stimuli, and in the reorienting of attention to relevant (Go) visualstimuli, respectively; and (3) a significantly smaller e-P3a amplitude in Middle-aged andOld groups, indicating a deficit in the orienting response to irrelevant novel and deviantauditory stimuli PB Frontiers Media YR 2016 FD 2016-03-30 LK http://hdl.handle.net/10347/16299 UL http://hdl.handle.net/10347/16299 LA eng NO Correa-Jaraba KS, Cid-Fernández S, Lindín M and Díaz F (2016) Involuntary Capture and Voluntary Reorienting of Attention Decline in Middle-Aged and Old Participants.
