SAACA suggests that most AS individuals are monotropic and that the monotropic disposition informs AS cognition and subsequent learning styles. This implies only being able to focus on one thing at one time, as long as it’s within our interest system. The implication of having a monotropic disposition is that generalising one’s experience and understanding is difficult. This could also have an impact upon the understanding of time because time might not be noted as a concept but rather only as a hindrance to being able to stay focused upon the thing that is holding our attention.
