Gaze Patterns of Children with Communication Difficulties Associated with Core Symptoms of Autism Spectrum Disorder.

Researchers studied how children aged 4-6 look at things on a screen to see if eye movements could help identify autism early. They found that children with social challenges preferred looking at shapes rather than faces, and those with communication difficulties looked less at people's eyes. These eye movement patterns were linked to autism traits, suggesting this could become a simple screening tool for autism in young children.

This study examined eye movement patterns in 4-6 year old children to identify potential early markers for autism spectrum disorder (ASD). Using data from the BirThree Cohort Study, researchers analyzed gaze patterns and correlated them with ASD characteristics measured by the Autism Spectrum Quotient Japanese version for children (AQ-J-child). Key findings revealed that children with social impairment preferred looking at geometric patterns, while those with communication difficulties spent less time looking at eyes in human face images. The study achieved a 92% median gaze rate, indicating good test execution.

Results showed significant associations between specific gaze preferences and core ASD symptoms including communication difficulties, social impairment, and impaired imagination, suggesting gaze patterns may serve as objective screening tools for ASD.

Gaze pattern analysis shows promise as an objective, non-invasive screening tool for autism in young children. The high test completion rate (92%) suggests feasibility for clinical use. However, further validation against gold-standard diagnostic assessments is needed before clinical implementation.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impaired social interactions. There is an urgent need to establish objective, simple, and accurate screening and diagnostic methods for ASD in childhood. Recently, the ability to visualize and quantify eye movements has emerged, suggesting that ASD may exhibit characteristic gaze patterns. To examine the potential of gaze patterns as an early marker of ASD, we analyzed the relationship between gaze patterns at ages 4-6 and individual ASD characteristics, as determined by the Autism Spectrum Quotient Japanese version for children (AQ-J-child) at age 6, using data from 4- to 6-year-old children recruited into the BirThree Cohort Study of the Tohoku Medical Megabank Project.

The median gaze rate, which represents the percentage of time the subjects spent looking at the screen during the test, was 92%, reflecting the highly versatile nature and proper execution of this test in our study. We found that children with social impairment tend to prefer looking at geometric patterns. In addition, children with communication difficulties tend to spend less time looking at the eyes in still images of human faces. Our analyses of the relationships between various gaze results and ASD characteristics defined by AQ-J-child revealed that specific gaze preferences are significantly associated with communication difficulties, social impairment, and impaired imagination.

These findings indicate that the gaze measurement results show strong correlations with specific aspects of ASD. Therefore, gaze patterns demonstrate the potential to reflect one aspect of ASD.
