Watching the same movie over and over is a common behavior in individuals with autism spectrum disorder (ASD). It can be a source of comfort and security, and it can also help to reduce anxiety. Repetitive behaviors are common in autism, and they can serve a variety of functions, including self-regulation, sensory stimulation, and communication.
There are a number of reasons why individuals with ASD may find comfort in watching the same movie over and over. The predictability and familiarity of the movie can provide a sense of safety and security. The repetitive nature of the movie can also help to reduce anxiety. In addition, the movie may provide sensory stimulation that is calming or enjoyable. Watching the same movie over and over can also be a way for individuals with ASD to communicate their interests and preferences.
