Effect of Social Stimuli on Postural Responses in Individuals with Autism Spectrum Disorder.
Faces make kids with autism lose balance—plan seating or hand support before eye-contact drills.
01Research in Context
What this study did
Ghanouni et al. (2017) watched how kids with autism stood still while looking at faces or objects. They used a force plate to measure tiny body wobbles. The team compared kids with autism to typically developing peers.
What they found
Children with autism swayed more when they saw faces than when they saw objects. Their peers without autism showed no difference. The sway grew even larger for kids with more severe autism traits.
How this fits with other research
LeBlanc et al. (2003) first showed that kids with autism wobble more under any changed sensory condition. Parisa adds that social pictures, not just blurry vision, can trigger that wobble.
Martín-Díaz et al. (2026) pooled 34 studies and confirmed poorer balance in autism. The new twist: faces alone can act like a balance challenge.
Kaartinen et al. (2016) found that kids who stay physiologically tense during eye contact have worse social skills. Parisa links the same social stress to a visible motor sign—more sway.
Why it matters
Expect more rocking, toe-tapping, or falling when you ask a child with autism to look at you. Offer a chair, a wall, or a footstool during face-to-face work. Start teaching social skills while the child is already seated or leaning against something sturdy.

03Original abstract
This study was aimed to investigate the effects of social versus non-social stimuli on postural responses in 21 boys with autism spectrum disorder (ASD) (mean age of 11.6 ± 1.5) compared with 30 typically developing (TD) boys (mean age of 11.7 ± 1.8). Postural control of children was examined while they were standing on a force plate and viewing images of an object, male face, or female face in sequence. Each image was shown in two trials and each trial lasted for 20 s. Results indicated a significant interaction between group and task (p < 0.05), meaning that children with ASD but not TD children showed an increased postural sway during face tasks than during object task. Furthermore children with higher autism severity compared to those with lower severity showed an increased change in response to social stimuli (p < 0.01). It seems that the postural control of children with ASD was more affected by the social stimuli than TD children.
