A frown or a smile? Children with autism can...( angry expressions the brain may quiet ...),Health

angry expressions, the brain may quiet down, because when a negative gaze is averted, it is no longer seen as a direct threat. Gaze has a huge impact on our brains because it conveys part of the meaning of that expression to the individual. It cues the individual to what is significant, Davies said.

While the results show the key role of eye gaze in signaling communicative intent, it also shows that autistic children, even when gazing directly into someones eyes, dont recognize visual cues and dont process that information. That may be why children diagnosed with autism have varying degrees of impairment in communication skills and social interactions and display restricted, repetitive and stereotyped patterns of behavior.

They dont pick up whats going on they miss the nuances, the body language and facial expressions and sometimes miss the big picture and instead focus on minor, less socially relevant details, Davies said. That, in turn, affects interpersonal bonds.
