Emotional Arousal-Induced Episodic Memory Benefits Are Attenuated in Autism Spectrum Disorders, Especially in Older Age / Sidni A. JUSTUS in Autism Research, 18-9 (September 2025)  

Public ISBD [article]  inAutism Research > 18-9 (September 2025) . - p.1817-1829 Titre : Emotional Arousal-Induced Episodic Memory Benefits Are Attenuated in Autism Spectrum Disorders, Especially in Older Age Type de document : texte imprimé Auteurs : Sidni A. JUSTUS, Auteur ; Emily HUTSON, Auteur ; Justin SUMME, Auteur ; Audrey DUARTE, Auteur Article en page(s) : p.1817-1829 Langues : Anglais (eng) Mots-clés : aging  arousal-enhanced memory  ASD  autism  depression  emotional memory Index. décimale : PER Périodiques Résumé : ABSTRACT Autism Spectrum Disorder (ASD) is a common neurodevelopmental disorder associated with episodic memory impairment. Although emotional factors such as arousal, as well as age and depression symptoms, are known to influence episodic memory in neurotypical (NT) populations, how these factors affect memory processes in ASD, which is associated with a higher prevalence of depression, remains unclear. In this large-scale online study, 326 adults (ages 18 67) with or without ASD (n=163 per group) and varying levels of depressive symptoms rated their experienced arousal of positive, negative, and neutral images and performed a recognition task 48 h later. Adults with ASD reported lower arousal for positive images and exhibited reduced arousal-enhanced memory benefits for both positive and negative images compared to NT adults, independent of depression severity. Age further exacerbated this reduced arousal memory benefit in the ASD group, specifically for positive stimuli. These findings underscore the role of atypical emotional arousal in ASD on episodic memory, with age-related declines suggesting accelerated vulnerability in positive memory retention.

The Utility of the R-ABC in Assessing Risk for Autism Compared With the M-CHAT: An Exploratory Study / Sidni A. JUSTUS in Focus on Autism and Other Developmental Disabilities, 39-4 (December 2024)

This study is a follow-up, 3 to 8 years later, with parents/caregivers of 57 children previously enrolled in a U.S. university-based study evaluating early ASD-risk. The original study evaluated infants' (ages 15-35 months) ASD-risk through both observation-based and parent-report screeners. At follow-up, caregivers completed a phone interview inquiring about their child?s developmental progress and diagnostic outcomes. Results indicated screener at-risk status agreement in infancy predicted only one of the four parent-reported ASD diagnoses at follow-up. Single instrument at-risk status aligned with two additional ASD diagnoses (one per screener), and both screeners missed one ASD diagnosis at follow-up. Results did not indicate significant added utility for the observation-based screener over the commonly used parent-report screener, suggesting that ASD behavioral markers may be hard to observe at early ages.
