Event-related brain potentials (ERPs) associated with the automatic detection of unattended infrequent (deviant/novel) auditory stimuli (MMN), the orienting response to these stimuli (P3a) and the reorienting of attention (RON) to visual relevant stimuli were evaluated. Middle-aged and old adults, relative to young, showed a decline in processing of irrelevant stimuli and the posterior reorienting of attention to relevant stimuli. MMN and P3a components may be useful psychophysiological markers for the diagnosis of aMCI and for distinguishing between aMCI subtypes.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Involuntary attentionEvent-related brain potentials (ERPs)Healthy aging and amnestic Mild Cognitive Impairment (aMCI)Materias::Investigación::61 Psicología::6106 Psicología experimental::610610 Psicología fisiológicaMaterias::Investigación::61 Psicología::6108 Psicología de la vejez::610803 Senectuddoctoral thesisopen access
