Some studies have reported a deficit in facial emotion processing in people with MCI or AD. However, it is unclear whether this deficit is also present in older people with SMCs. The present study used behavioral measurements and event-related potentials (ERPs) to investigate the facial emotion processing of 41 older people with SMCs and 38 without SMCs. The task contained 204 images displaying facial emotions (positive, negative, and neutral). In terms of behavior, our results showed that participants with SMCs were slower and less accurate than controls. In terms of ERPs, the N170 latency was longer in men with SMCs than in controls, whereas no differences were observed between groups in the P300 and late positive potential (LPP) latencies or amplitudes. Moreover, in participants with SMCs, higher P300 and LPP amplitudes were related to better performance on working memory, psychomotor speed, and attention. Additionally, women were faster and more accurate than men on the facial emotion-processing task. In sum, these results suggest that older people with SMCs may have deficits in the processing of facial expressions of emotion. However, this deficit seems to affect the structural encoding of faces, rather than the late stages of processing. info:eu-repo/grantAgreement/ES/DGA/S31-20D info:eu-repo/grantAgreement/ES/MICINN/PSI2016-78763-P info:eu-repo/grantAgreement/ES/MICINN/PSI2017-90806-REDT info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 4.348 2021 PSYCHOLOGY, BIOLOGICAL 3 / 14 = 0.214 2021 Q1 T1 PSYCHOLOGY, EXPERIMENTAL 18 / 91 = 0.198 2021 Q1 T1 PSYCHOLOGY 20 / 81 = 0.247 2021 Q1 T1 PHYSIOLOGY 22 / 81 = 0.272 2021 Q2 T1 NEUROSCIENCES 114 / 275 = 0.415 2021 Q2 T2 1.461 2021 Endocrine and Autonomic Systems 2021 Q1 Experimental and Cognitive Psychology 2021 Q1 Cognitive Neuroscience 2021 Q1 Physiology (medical) 2021 Q1 Neurology 2021 Q1 Neuroscience (miscellaneous) 2021 Q1 Physiology 2021 Q1 Developmental and Educational Psychology 2021 Q1 6.5 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Garrido-Chaves, Ruth Zapater-Fajari, Mariola Pulopulos, Matias M.
