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.

Prediction of social behavior in autism spectrum disorders: Explicit versus implicit social cognition / Cara M. KEIFER in Autism, 24-7 (October 2020)  

Public ISBD [article]  inAutism > 24-7 (October 2020) . - p.1758-1772 Titre : Prediction of social behavior in autism spectrum disorders: Explicit versus implicit social cognition Type de document : texte imprimé Auteurs : Cara M.

Matthew Lerner declares that he has no conflict of interest. Index. décimale : PER Périodiques Résumé : Difficulties with social communication and interaction are a hallmark feature of autism spectrum disorder. These difficulties may be the result of problems with explicit social cognition (effortful and largely conscious processes) such as learning and recalling social norms or rules. Alternatively, social deficits may stem from problems with implicit social cognition (rapid and largely unconscious processes) such as the efficient integration of social information. The goal of this study was to determine how problems in explicit and implicit social cognition relate to social behavior in 34 youth with autism spectrum disorder. We measured aspects of implicit and explicit social cognition abilities in the laboratory using behavioral, cognitive, and brain (electrophysiological) measures. We then used those measures to predict "real-world" social behavior as reported by parents, clinicians, and independent observers. Results showed that overall better aspects of implicit and explicit social cognition predicted more competent social behavior. In addition, the ability to fluidly integrate social information (implicit social cognition) was more frequently related to competent social behavior that merely knowing what to do in social situations (explicit social cognition). These findings may help with the development of interventions focusing on improving social deficits.

Social Anhedonia Accounts for Greater Variance in Internalizing Symptoms than Autism Symptoms in Autistic and Non-Autistic Youth / Alan H. GERBER in Journal of Autism and Developmental Disorders, 55-3 (March 2025)

It has historically been associated with autism, however, very few studies have directly examined behavioral symptoms of social anhedonia in autistic youth. We investigated rates of social anhedonia in autistic compared to non-autistic youth and the relative contributions of autism and social anhedonia symptoms to co-occurring mental health.

Structural hierarchy of autism spectrum disorder symptoms: an integrative framework / Hyunsik KIM in Journal of Child Psychology and Psychiatry, 59-1 (January 2018)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 59-1 (January 2018) . - p.30-38 Titre : Structural hierarchy of autism spectrum disorder symptoms: an integrative framework Type de document : texte imprimé Auteurs : Hyunsik KIM, Auteur ; Cara M. KEIFER, Auteur ; Craig RODRIGUEZ-SEIJAS, Auteur ; Nicholas R. EATON, Auteur ; Matthew D. LERNER, Auteur ; Kenneth D. GADOW, Auteur Article en page(s) : p.30-38 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  classification  structural hierarchy  Child and Adolescent Symptom Inventory  bass-ackwards Index. décimale : PER Périodiques Résumé : Background In an attempt to resolve questions regarding the symptom classification of autism spectrum disorder (ASD), previous research generally aimed to demonstrate superiority of one model over another. Rather than adjudicating which model may be optimal, we propose an alternative approach that integrates competing models using Goldberg's bass-ackwards method, providing a comprehensive understanding of the underlying symptom structure of ASD. Methods The study sample comprised 3,825 individuals, consecutive referrals to a university hospital developmental disabilities specialty clinic or a child psychiatry outpatient clinic. This study analyzed DSM-IV-referenced ASD symptom statements from parent and teacher versions of the Child and Adolescent Symptom Inventory-4R. A series of exploratory structural equation models was conducted in order to produce interpretable latent factors that account for multivariate covariance. Results Results indicated that ASD symptoms were structured into an interpretable hierarchy across multiple informants. This hierarchy includes five levels; key features of ASD bifurcate into different constructs with increasing specificity. Conclusions This is the first study to examine an underlying structural hierarchy of ASD symptomatology using the bass-ackwards method. This hierarchy demonstrates how core features of ASD relate at differing levels of resolution, providing a model for conceptualizing ASD heterogeneity and a structure for integrating divergent theories of cognitive processes and behavioral features that define the disorder. These findings suggest that a more coherent and complete understanding of the structure of ASD symptoms may be reflected in a metastructure rather than at one level of resolution.
