Emotional Arousal-Induced Episodic Memory Benefits Are Attenuated in Autism Spectrum Disorders, Especially in Older Age.

PMID 40657939WHAT IT FOUND
Adults with autism showed a smaller memory boost from high-arousal images than neurotypical adults.
This gap for positive images widened with age, while depression reduced arousal ratings but did not explain the memory differences.
Key findings
01Adults with ASD had lower arousal-enhanced memory benefits for positive items than did NT adults.
02Older age was associated with decreased arousal-enhanced memory benefits for positive images in adults with ASD.
03Depression symptoms were associated with decreased arousal for positive images but were not a significant predictor of arousal-enhanced memory.

What it does not show
The study was conducted online, so ASD diagnoses were self-reported and not confirmed with standard clinical tools like the ADOS-2. The NT group did not complete autism trait questionnaires, so some participants with elevated autistic traits may have been included in the control group. Physiological arousal was not measured, so results rely entirely on self-reported emotional intensity. The sample required technical proficiency to complete online tasks, which may exclude individuals with more severe support needs.
Declared interests
The authors declare no conflicts of interest. The study was funded by the National Science Foundation and the National Institute on Aging.
The easy way to misread this
Do not conclude that adults with autism have a general memory impairment or that depression is the cause of their emotional memory differences. Overall memory performance was similar between groups; the specific deficit was in leveraging arousal to boost memory, and depression did not predict this memory gap.
