Autistic Children Immune to Yawns?

From Mind Hacks

So a group of researchers, led by psychologist Dr. Atsushi Senju, wondered whether children with autism might be less susceptible to yawn contagion.

They came up with the ‘I wish I’d thought of that’ idea of showing videos of people yawning to groups of typically developing children, and children with a diagnosis of autism.

The study [pdf] showed that children with autism were far less likely to yawn in response to watching others do the same.
