Autism symptoms not explained by impaired attention

Autism is marked by several core features — impairments in social functioning, difficulty communicating, and a restriction of interests. Though researchers have attempted to pinpoint factors that might account for all three of these characteristics, the underlying causes are still unclear.

Now, a new study suggests that two key attentional abilities — moving attention fluidly and orienting to social information — can be checked off the list, as neither seems to account for the diversity of symptoms we find in people with autism.
