Oculomotor deficits in children with sensory processing difficulties.
Timothy L Hodgson, Phoebe Cartwright, Joseph Dodd and 1 others
PMID 40421443WHAT IT FOUND
Children with sensory processing difficulties made more errors on anti-saccade tasks and showed less accurate vertical eye tracking.
They had faster reaction times for correct anti-saccades. No differences were found in basic saccade timing or amplitude.
Key findings
01Children with SPD made significantly more errors in the anti-saccade task compared to controls.
02Children with SPD showed significantly larger amplitude saccades during horizontal smooth pursuit but not vertical pursuit.
03Children with SPD made significantly more saccades away from the target during sustained fixation compared to controls.

What it does not show
The sample size was very small (10 children with SPD). The SPD group was entirely male, while the control group was mixed gender, though analyses were repeated for males only. Most children with SPD had comorbid neurodevelopmental diagnoses (ASD, ADHD), making it difficult to isolate sensory processing deficits. Eye-tracking technology is expensive and lacks standardised norms for children.
Declared interests
The authors declared no potential conflicts of interest and no financial support for the research.
The easy way to misread this
Do not assume these eye-tracking deficits are specific to sensory processing difficulties alone. The children in the SPD group had comorbid conditions like ASD and ADHD, which are also associated with oculomotor differences, so the findings may reflect broader neurodevelopmental issues rather than SPD in isolation.
