Eye tracking reveals how kids with autism see the world differently
NCT ID NCT07597694
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study used eye-tracking technology to understand how children with autism spectrum disorder (ASD), intellectual disability (ID), and typically developing children process visual cues. Researchers showed 80 children videos of a model choosing objects and recorded their eye movements. The goal was to identify differences in attention and gaze patterns that could help improve understanding of autism.

Who is studied
A total of 80 children (aged 3-10 years) were initially recruited and divided into three groups: 29 typically developing (TD) children (25 boys, 4 girls) from a kindergarten or primary school in Sichuan Province; 26 children with autism spectrum disorder (ASD) (20 boys, 6 girls) from a local disability federation or autism rehabilitation center in Chengdu, Sichuan Province, all clinically diagnosed and assessed with the Autism Diagnostic Observation Schedule (ADOS); and 25 children with intellectual disability (ID) (14 boys, 11 girls) from a disability federation or rehabilitation center in Chengdu, Sichuan Province, all clinically diagnosed. Based on eye-tracking data, 4 ASD participants and 1 ID participant whose total fixation duration accounted for less than 50% of the total trial time were excluded. Consequently, the final sample included 29 TD children (25 boys, 4 girls), 22 ASD children (18 boys, 4 girls), and 24 ID children (13 boys, 11 girls) for data analysis.
