Intact Visual Correlation Detection in Autistic Adults.

PMID 42544756WHAT IT FOUND
Autistic adults detected which visual disk flashed more often with a surrounding ring as accurately as non-autistic adults.
The small apparent advantage was explained by higher nonverbal reasoning scores, so this visual correlation task appears intact.
Key findings
01After nonverbal IQ was accounted for, autistic adults were not less accurate than non-autistic adults at detecting visual correlation.
02In the full sample, mean accuracy was 90.2% for autistic adults and 86.0% for non-autistic adults, but the group effect was not significant once IQ was included.
03Higher autistic traits and more prediction-related challenges were not linked to worse correlation-detection performance.

What it does not show
The autistic group had higher nonverbal IQ scores than the non-autistic group, and IQ was related to task performance, so the null finding depends on statistical adjustment and a matched subset. The sample included independently living, cognitively able autistic adults recruited through SPARK, so it may not represent autistic people with lower language ability, lower nonverbal IQ, or more profound support needs. The task tested only visual correlation detection over short 10-second trials, so it does not show that auditory, multisensory, communication, or everyday prediction tasks are intact. ADHD was common in the autistic group but excluded from the non-autistic group; subgroup analyses did not change the result, but the groups were not matched for ADHD.

The easy way to misread this
Do not conclude that autistic adults outperform non-autistic adults because the full-sample means were 90.2% and 86.0%. That apparent advantage was not significant after nonverbal IQ was included, and the IQ-matched groups scored 88.5% and 88.7%.
