The causes of social communication deficits in ASD

This week, former ASF fellow Katherine Stavropoulos from UC Riverside and Leslie Carver published data investigating what is the core cause of social communication deficits in autism.  Do people with autism show deficits in this area because they have a lack of motivation for social cues, or are social interactions just too overwhelming on their senses?  It turns out, both are true and this has direct implications for intervention methods.  Also, parents and siblings of people with autism show subtle symptoms of ASD without having a diagnosis.  This is called the broader autism phenotype, and a study by the Study to Explore Early Development led by Dr. Eric Rubenstein, demonstrated that parents of children with a particular group of symptoms are more likely to show this phenotype than other groupings.  You can read the full studies here:
