In recent years, autism has been at the center of a controversial interdisciplinary discussion. Alongside the expanded criteria for diagnosing autism, early diagnosis in early childhood, and refined tools for capturing autistic behaviors, the debate has increasingly focused on criticism of the pathologization of autistic behavior. The consequence of this development is a multitude of new technical and key terms, as well as reinterpretations of existing terms. The book addresses all essential key terms that are significant both practically and theoretically, providing a solid scientific guide. Professor Dr. Georg Theunissen holds the chair in Special Education for Individuals with Intellectual Disabilities and Education for Autism at the Institute for Rehabilitation Education at the University of Halle-Wittenberg.
