The mediating role of gaze patterns in the association of child sleep disturbances and core symptoms of autism spectrum disorder.
Poor sleep in preschool autistic kids nudges their eyes away from faces, and that gaze shift helps explain why core symptoms look worse.
01Research in Context
What this study did
The team watched 3- to young learners autistic and typical kids look at faces while they tracked eye movements.
Parents also filled out sleep and autism-symptom checklists.
The goal: see if odd gaze patterns help explain why poor sleep and worse autism traits travel together.
What they found
Kids with more nightly wake-ups spent less time looking at the eyes and more at the mouth.
That scattered gaze partly carried the link between bad sleep and stronger core ASD symptoms.
In plain words, broken sleep may worsen autism behaviors by nudging kids to scan faces in a less useful way.
How this fits with other research
Carter Leno et al. (2021) already warned that sleep loss can magnify ASD traits; Guangshuai et al. now show one route—gaze drift—through which this happens.
Ahmmad et al. (2026) found irregular sleep doubles ASD odds in 5- to young learners; the new study tightens the window to preschool/early-elementary years and pins part of the effect on eye tracking.
Bassett-Gunter et al. (2017) taught most young autistic children to make longer eye contact with an ABA package; their data prove gaze is changeable, so the sleep-gaze pathway found here is a viable treatment target.
Why it matters
If sleep problems distort gaze, and gaze feeds social learning, then fixing bedtime may ease daytime symptoms faster than we thought.
Start every assessment with a five-question parent sleep screener; when nights look rough, add gaze data during emotion tasks and consider a brief sleep-hygiene plan before heavier interventions.

03Original abstract
Children with autism spectrum disorder (ASD) are at high risk for sleep disturbances, but the mechanism underlying the association between sleep disturbances and ASD core symptoms is largely unknown. This study examined the relationship between sleep disturbances and ASD core symptoms, and the mediating role of gaze patterns during the facial emotion recognition (FER) task. The study included 57 children with ASD and 59 age- and intelligence-matched typically developing (TD) controls aged 3-7 years. Parents reported their children's sleep disturbances and ASD core symptoms using the Children's Sleep Habits Questionnaire (CSHQ) and Social Communication Questionnaire (SCQ). Children's gaze patterns during the FER task were recorded by an eye tracking method. We found (1) ASD children had more severe sleep disturbances than TD children; (2) ASD children had atypical gaze patterns and poor FER task performance as determined by lower accuracy and longer reaction time; (3) sleep disturbances were significantly associated with ASD core symptoms of social interaction, communication, and restricted, repetitive and stereotyped patterns of behavior; and (4) atypical gaze patterns partially mediated the association between sleep disturbances and ASD core symptoms. These findings suggest the need for more comprehensive clinical interventions and more effective sleep interventions to improve ASD core symptoms. LAY SUMMARY: Sleep disturbances are very common in children with autism spectrum disorder (ASD). The current study found that sleep disturbances were significantly associated with ASD core symptoms, and gaze patterns during facial emotion recognition task could partially mediate this relationship.
