Autism is primarily a disorder of social interaction. People with autism struggle to make and keep friends. Their struggle with “social reciprocity” means they do not understand the give-and-take of social relationships. They struggle to communicate, and social interactions tend to feel awkward. Individuals with autism might not get jokes, analogies, or metaphors. When an adult says, “button your lip,” a child with autism might think, “uh, no thank you. That would hurt.” Humorous and sarcastic comments are often misunderstood. Some individuals with autism sound a little odd when they talk. For example, they might use lots of big words or sound very formal. An individual with autism might use a robotic, sing-song, or high-pitched voice. People with autism tend to have favorite topics. They might go on and on about their favorite video game or movie, sometimes inserting quotes from that movie in their everyday speech. For example, a child might say “to infinity and beyond” after every question on a test. Often, children with autism do not play the way other children do. They might struggle to take on the part of a doll or an action figure. People with autism may need to be reminded to tune in with the conversation or to come join others in a game.
