Children with autism spectrum disorders (ASD) lack the ability to share attention with others. This is a key symptom for diagnosing an ASD. The inability to reference the joint attention of another negatively impacts a child's language and social skill development. This study investigated whether three preschool boys, diagnosed with ASD, could be taught to detect an adult's eye gaze direction, to obtain a motivational item. Treatment improved all of the participants' ability to reference the trainer's eye gaze and use the trainer's eye direction to locate a concealed reinforcer. If children with ASD can improve their ability to share attention, this may positively affect their language and social skill development.
