Autism symptoms not explained by impaired attention
Date:7/30/2013

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.

"This is not to say that every aspect of attention is fine in all children with autism children with autism very often have attentional disorders as well," explain psychological scientists and lead researchers Jason Fischer and Kami Koldewyn of MIT. "However, our study suggests that attention impairments are not a key component of autism itself."

The study is published in Clinical Psychological Science, a journal of the Association for Psychological Science.

Attention has long been targeted as a possible causal mechanism in autism research:

"Problems with attention early in life could have far-reaching consequences," say Fischer and Koldewyn. "For example, if young children with autism don't pay close attention to the behaviors of the people around them, they might never learn to read body language and other social cues."

But much of the previous research on attention, social learning, and autism had been mixed.

"Some of the most fundamental questions remain debated," Fischer and Koldewyn explain. "Our goal was to conduct careful, systematic, relatively large-scale studies of some of the mental processes most often implicated in autism to discover which of them are actually disrupted in autism and which are not."

To investigate this, Fischer, Koldewyn, and their team had children with high-functioning autism and children without autism complete an attention tas
