Neurophysiological characteristics of acts of remembering in the process of positive ageing / Características neurofisiológicas de los actos de recuerdo en el proceso de envejecimiento positivo

Abstract ‘Acts of remembering’ refer to the conscious cognitive process that facilitates recognition of socioculturally relevant events. This study presents an analysis of the differences and similarities between the morphological characteristics and architecture of Event-Related Potentials associated with the visual recognition of cultural events, by comparing a group of older adults (n = 15) with a group of young adults (n = 17). The results show similar modulations in the N1, P2, P300 and N400 components while a differential modulation appears in N200, a component that has been associated with attentional processes. Two ways of interpreting the results are put forward: one suggests that with age come greater difficulties for cognitive processing and the other suggests that older adults have a particular interest in this type of material.
