Abstract
An intense focus on certain interests or items, characterized by the drive to pursue and prolong engagement with them, is a significant feature of autism. Generally known as ‘restricted interests’, these are observed in most autistic individuals. This paper critiques the deficit-based terminology used to describe this phenomenon and supports the adoption of the term ‘intense interest’ as a strengths-based alternative. We expand the argument, clarify its psychological nature, and present underlying reasons for its adoption with acknowledgement of its positive, agent-centred attributes. Recognising the strengths of intense interests can enhance professional care and education, to support academic and social competencies.
