Oculomotor performance in children with high-functioning Autism Spectrum Disorders.

Researchers compared eye movements of high-functioning kids with autism to typically developing peers. They used lab cameras to track how fast each child moved their eyes side-to-side and how well they followed a slow moving target up and down.

The autism group moved their eyes more slowly when jumping from one spot to another. They also lagged behind when smoothly tracking a vertical target. These tiny timing gaps showed up even though the kids were bright and verbal.

Kovarski et al. (2019) seems to say the opposite: their young autism group moved eyes faster, not slower. The difference is age and task. Klara tested toddlers through early elementary kids with no instructions; J et al. tested older, high-functioning children during guided tasks. Speed versus accuracy trade-offs explain the clash.

Carson et al. (2017) extend the story by showing the same high-functioning kids also have jerkier eye-stabilization after spinning. Together the papers map a pattern: basic eye-control circuits are off in autism, whether the move is voluntary or reflex.

Crippa et al. (2013) came first, finding poor eye-hand timing in autism during gap-overlap tests. The new data confirm the eye side of that problem: the motor command leaves the brain late.

If a client with autism seems to look away too long or miss visual cues, the issue may be hard-wired eye timing, not inattention. You can adjust teaching materials: give extra pause time, use larger targets, and check understanding verbally. These eye delays could also become cheap biomarkers to track progress or tailor therapy.
