Late Positive Potential ERP Responses to Social and Nonsocial Stimuli in Youth with Autism Spectrum Disorder / Stephen D. BENNING in Journal of Autism and Developmental Disorders, 46-9 (September 2016)

Social stimuli were faces with positive expressions and nonsocial stimuli were related to common restricted interests in ASD (e.g., electronics, vehicles, etc.). The ASD group demonstrated relatively smaller LPP amplitude to social stimuli and relatively larger LPP amplitude to nonsocial stimuli. There were no group differences in subjective ratings of images, and there were no significant correlations between LPP amplitude and ASD symptom severity within the ASD group. LPP results suggest blunted motivational responses to social stimuli and heightened motivational responses to nonsocial stimuli in youth with ASD.

Late positive potentials elicited by negative self-referential processing predict increases in social anxiety, but not depressive, symptoms from age 11 to age 12 / Jaron X.Y. TAN in Development and Psychopathology, 37-4 (October 2025)  

Public ISBD [article]  inDevelopment and Psychopathology > 37-4 (October 2025) . - p.1985-1995 Titre : Late positive potentials elicited by negative self-referential processing predict increases in social anxiety, but not depressive, symptoms from age 11 to age 12 Type de document : texte imprimé Auteurs : Jaron X.Y. TAN, Auteur Article en page(s) : p.1985-1995 Langues : Anglais (eng) Mots-clés : depression  late positive potential  longitudinal  self-schematic processing  social anxiety Index. décimale : PER Périodiques Résumé : Social anxiety and depression exacerbate in early adolescence. Maladaptive self-referential processing confers risk for both conditions and can be assessed by the Self-Referent Encoding Task (SRET). Our cross-sectional findings indicated that the SRET-elicited anterior late positive potential (LPP) was uniquely associated with social anxiety symptoms, whereas behavioral SRET scores were uniquely associated with depressive symptoms. Expanding this work, this study investigated whether the SRET-generated behavioral and LPP indices differentially predicted changes of social anxiety or depressive symptoms over time. At baseline, 115 community-dwelling youths (66 girls; Mean age/SD = 11.00/1.16 years) completed an SRET with EEG. Youths reported social anxiety and depressive symptoms at baseline and ?six and ? 12 months later, based on which the intercept and slope of symptoms were estimated as a function of time. A larger anterior LPP in the negative SRET condition uniquely predicted a larger slope (faster increase) of social anxiety (but not depressive) symptoms. Greater positive behavioral SRET scores marginally predicted a smaller slope (slower increase) of depressive (but not social anxiety) symptoms. We provided novel evidence concerning the differential, prospective associations between self-referential processing and changes of social anxiety and depressive symptoms in early adolescence.
