Quizplus · Accepted Answer

Peter's behavior is characteristic of autism, which involves impairments in social interaction, communication, and repetitive behaviors or interests. Lack of eye contact, smiling, and verbal responsiveness are common features of autism, as well as appearing indifferent to others. Mental retardation, obsessive-compulsive disorder, and childhood schizophrenia may involve some similar behaviors, but they would not necessarily include all of the features described.
