Adults with and without ASD completed a facial emotion recognition task involving stimuli that varied by emotional intensity while electroencephalograms were recorded. Principal components analysis was used to examine P300 and late positive potential (LPP) modulation by emotional intensity. Results indicated that greater ASD symptomatology evinced heightened P300 to high relative to low intensity faces, then heightened LPP to low relative to high intensity faces. Findings suggest that adults with greater ASD symptomatology may demonstrate a lag in engagement in elaborative processing of low intensity faces.

Vocal Emotion Recognition in Autism: Behavioral Performance and Event-Related Potential (ERP) Response / Talena C. DAY in Journal of Autism and Developmental Disorders, 54-4 (April 2024)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 54-4 (April 2024) . - p.1235-1248 Titre : Vocal Emotion Recognition in Autism: Behavioral Performance and Event-Related Potential (ERP) Response Type de document : texte imprimé Auteurs : Talena C. DAY, Auteur ; Isha MALIK, Auteur ; Sydney BOATENG, Auteur ; Kathryn M. HAUSCHILD, Auteur ; Matthew D. LERNER, Auteur Article en page(s) : p.1235-1248 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Autistic youth display difficulties in emotion recognition, yet little research has examined behavioral and neural indices of vocal emotion recognition (VER). The current study examines behavioral and event-related potential (N100, P200, Late Positive Potential [LPP]) indices of VER in autistic and non-autistic youth. Participants (N = 164) completed an emotion recognition task, the Diagnostic Analyses of Nonverbal Accuracy (DANVA-2) which included VER, during EEG recording. The LPP amplitude was larger in response to high intensity VER, and social cognition predicted VER errors. Verbal IQ, not autism, was related to VER errors. An interaction between VER intensity and social communication impairments revealed these impairments were related to larger LPP amplitudes during low intensity VER. Taken together, differences in VER may be due to higher order cognitive processes, not basic, early perception (N100, P200), and verbal cognitive abilities may underlie behavioral, yet occlude neural, differences in VER processing.
