Episodic Autobiographical Memory in Adults With Autism Spectrum Disorder: An Exploration With the Autobiographical...

Area of Science:

• Neuroscience
• Psychology

Background:

• Conflicting literature exists on episodic memory in autism spectrum disorder (ASD).
• Methodological variations across studies may explain discrepancies.
• Autobiographical memory, a key aspect of episodic memory, is often impaired in ASD.

Purpose of the Study:

• To investigate episodic memory in adults with ASD using the Autobiographical Interview.
• To assess the number and richness of phenomenological memory details before and after retrieval support.
• To clarify the status of autobiographical memory in ASD and challenge previous findings.

Main Methods:

• Twenty-five adults with ASD and 25 controls recalled six autobiographical events.
• Memory details (number and richness) were assessed globally and by category.
• A cueing phase with specific questions was used to elicit further details.

Main Results:

• No significant group differences in detail richness were observed.
• The number of internal details was lower in ASD individuals only after cueing, specifically for contextual details.
• Spontaneous recall showed no relevant group differences in detail quantity.

Conclusions:

• Results suggest no clear impairment of autobiographical memory episodicity in ASD.
• Findings challenge previous research indicating reduced specificity and episodicity in ASD.
• Further research is needed to fully understand episodic autobiographical memory in ASD.
