Underlying Mechanisms of Restricted and Repetitive Behaviors Across Typical and Atypical Development

Abstract

Restricted and repetitive behaviors and interests (RRBI) are a core feature of autism spectrum disorder (ASD) and occur across other neurodevelopmental disorders. They present a major barrier to learning and adaptation and a source of stress for parents. Despite their diagnostic prominence and clinical significance, mechanisms underlying RRBI are poorly understood. As a consequence, we currently lack effective individually tailored treatment options for RRBI. In this chapter we concentrate on restricted and repetitive behaviors (RRB), and will argue that one of the major obstacles to a better understanding of these behaviors in ASD has been that research thus far has been largely ASD-centric..
