Autism Affects Ability to Read Body Language

Problems processing visual information may stop those with autism from interpreting body language, harming their ability to gauge others' emotions, a study says.
Researchers from the University of Durham in England say people with autism have problems recognising physical displays of emotion, but also general difficulty perceiving certain sorts of motion.
With around half a million people in the UK affected by autism, the study suggests visual processing problems could be contributing to their day-to-day difficulties with social interaction.
The team studied 13 adults with autism and found the patients had difficulty identifying emotions such as anger or happiness when shown short animated video clips.
