Scene construction ability in neurotypical and autistic adults.
Marchella Smith, Lindsey Cameron, Heather J Ferguson
PMID 38153207WHAT IT FOUND
Autistic adults generated less coherent imagined scenes than neurotypical adults, but they used sensory details and self-reference just as often.
The difference in scene quality was linked more to difficulty identifying emotions and understanding others' minds than to autism diagnosis itself.
Key findings
01Neurotypical participants scored significantly higher on the experiential index, indicating better ability to mentally construct coherent, detailed scenes compared to autistic participants.
02There was no significant difference between autistic and neurotypical groups in how frequently they referenced sensory details or used first-person pronouns during scene construction.
03When cognitive predictors were analyzed, Theory of Mind and alexithymia scores predicted scene construction ability, whereas autism diagnosis and autistic traits did not.

What it does not show
The study is cross-sectional and does not establish causality. The sample consisted of adults with average to high IQs, so findings may not generalize to those with intellectual disabilities. The scene construction task was a specific laboratory measure and may not fully reflect real-world narrative abilities. The authors note that explicit prompts to include sensory details might have provided enough support to mask potential differences in sensory processing.
Declared interests
The authors declared no potential conflicts of interest. The research was supported by a grant from the Leverhulme Trust.
The easy way to misread this
Do not conclude that autistic adults have a general deficit in sensory processing or self-reference based on this study. They used these elements as frequently as neurotypical adults; the difference lay in the overall coherence and quality of the constructed scene, which was better explained by emotional and social cognitive factors.
