More than 900 scientists, parents and activists from around the world who are focused on understanding the causes of autism and finding treatments for the developmental disorder will gather in Seattle May 3-5 to share the latest research findings at the sixth International Meeting for Autism Research.

Younger siblings of children with autism are at risk to suffer from delayed verbal, cognitive and motor development in their early childhood years.

New research from Columbia's Primate Cognition Laboratory has demonstrated for the first time that monkeys could acquire meta-cognitive skills: the ability to reflect about their thoughts and to assess their performance.

Autistic children are able to interpret the mental state of others by looking at their eyes, contrary to previous research, a new University of Nottingham study has found.

Autistic children have long been thought to have difficulty interpreting people's mental states based on facial expressions, especially expressions around the eyes. Some researchers believe that this lack of ability could be central to the social problems experienced by these children.
