Abnormal saccadic eye movements in autistic children.

The team watched how autistic kids moved their eyes. They used lab cameras to count quick jumps called saccades.

Kids looked at simple lights and pictures while the machine tracked every flick.

Autistic children made more extra eye jumps than peers. The jumps did not change when the picture changed.

This hints that their attention system ignores outside cues.

Caldani et al. (2020) saw the same thing: too many early jumps. Their newer gear shows the pattern is real and stable.

Ziv et al. (2024) went deeper. They turned jump counts into a randomness score and linked higher scores to worse ADOS ratings. Their finer metric updates the 1998 story.

Zalla et al. (2018) tested adults and still found odd jumps. The issue lasts past childhood and may tie to cerebellum wiring, not just attention.

Extra jumps can split attention during lessons or social cues. If a learner looks away too often, slow the task and use clear single signals. Eye-tracker data, even simple counts, can flag who needs this help.
