Binocular rivalry in children on the autism spectrum.
Themelis Karaminis, Claudia Lunghi, Louise Neil and 2 others
PMID 28301094WHAT IT FOUND
Autistic and typical children switched between pictures shown to each eye at a similar rate, but autistic children reported fewer blended views.
Key findings
01The number of perceptual transitions did not differ significantly between autistic and typical children.
02Autistic children reported a lower proportion of mixed perception and fewer mixed periods than typical children.
03For both groups, house/face stimuli produced fewer transitions and longer single-stimulus durations than grating stimuli.

What it does not show
The sample was small: 16 autistic and 20 typical children were analysed. Children with strong eye dominance were excluded, so the findings may not apply to children with that visual pattern. The groups differed in gender, with more girls in the typical group. All children had cognitive scores of at least 70, so the results may not apply to autistic children with more severe intellectual impairment. The study did not test a treatment or measure functional communication, social participation or daily living outcomes. The paper does not clearly name a single primary outcome, and several rivalry measures were compared. Children's recognition ability for the stimuli was not measured, so stimulus effects cannot be separated from recognition differences.
The easy way to misread this
Do not read fewer blended views as proof that autistic children have a general visual processing deficit or as a basis for therapy. The study tested a lab rivalry task in a small group of children, did not test a treatment, and several core rivalry measures were similar to typical children.
