Elliot works with autistic children and has developed a new app he thinks will improve their ability to track a conversation. He uses the app with the clients he works with at a private school for children with autism. He compare these children's performance in a conversation with peers to the performance of autistic children in the public school who have not used the app. Although Elliot notes
