This book introduces a novel approach for examining language and communication in autism spectrum disorder (ASD) - discourse and conversation analysis. The authors offer a set of very different perspectives on these complex issues than are typically presented in psychological and clinical work. Emerging from a range of social scientific fields, discourse and conversation analysis involve fine-grained qualitative analysis of naturally-occurring, rather than laboratory-based, interaction, enabling broad applications. Presented in two parts, this innovative volume first provides a set of pedagogical chapters to develop the reader's knowledge and skills in using these approaches, before moving to showcase the use of discursive methods through a range of original contributions from world-leading scholars, drawn from a range of disciplines including sociology, academic and clinical psychology, speech and language therapy, critical disability studies and social theory, and medicine and psychiatry.
