Visual Preference for Biological Motion in Children and Adults with Autism Spectrum Disorder: An Eye-Tracking Study.
Dzmitry A Kaliukhovich, Nikolay V Manyakov, Abigail Bangerter and 9 others
PMID 32951157WHAT IT FOUND
People with autism looked less at biological motion than controls but still preferred it over random dots.
They also took longer to start looking at anything. This reflects reduced attention to social cues, not a lack of interest.
Key findings
01The autism group spent significantly less time looking at biological motion compared to the control group, but both groups still preferred biological motion over non-biological motion.
02Individuals with autism had longer delays before their first fixation on both biological and non-biological motion, suggesting slower visual attention allocation overall.
03There was no significant relationship between the severity of autism symptoms and the preference for biological motion, nor between eye-tracking metrics and behavioral ratings.

What it does not show
The study was exploratory and not designed to test specific hypotheses about clinical change. The typically developing control group was smaller and less characterized than the autism group, lacking IQ data. Multiple comparison corrections were not applied to all analyses, increasing the risk of false positives. The study did not measure socioeconomic status. Attention to the center of the screen before each video was not verified, which may affect latency measures.

The easy way to misread this
Do not interpret the reduced preference for biological motion as a complete lack of social interest. Both groups preferred biological motion over non-biological motion, and the difference was small. The longer latency to first fixation suggests a general slowing of visual attention, not just a social deficit.
