The neurodiversity framework offers a transformative alternative to the traditional medical models in autism research. The concept of neurodiversity posits that human neurodevelopment is inherently heterogeneous. Although certain neurotypes are more prevalent within the population than others, there is no singular “correct” or normative type. This article begins by introducing the concept of neurodiversity and critically examines existing language and cognitive-behavioural studies on autistic children within traditional medical frameworks. It argues that, from the neurodiversity perspective, the core objective of language research on autistic children is to investigate their natural trajectories of language development so as to identify their strengths and communicative resources, to foster inclusive communicative environments, and to support them in using language for effective communication, and ultimately to enhance their autonomy, agency, and well-being. To achieve this goal, this article proposes a three-level shift in research approaches. First, at the philosophical level, it advocates the construction of an autonomous framework for language research on autism that does not rely on neurotypical traits as a comparative baseline. Second, at the methodological level, it emphasizes the incorporation of first-hand accounts of autistic experiences and taking autistic traits seriously as part of the research design. Finally, in terms of research content, it argues for a focus on pragmatic competence, particularly on how autistic children use language in social interaction, with the goal of empowering them as confident and effective communicators.
