Written by some of the leading figures in the fields of conversation analysis, discursive psychology and ethnomethodology, this book looks at the challenging implications of new discourse-based approaches to the topic of cognition. Up to now, cognition has primarily been studied in experimental settings. This volume shows how cognition can be reworked using analyses of engaging examples of real life interaction such as conversations between friends, relationship counselling sessions, and legal hearings. It includes an extended introduction that overviews the history and context of cognitive research and its basic assumptions to provide a frame for understanding the specific examples discussed, as well as surveying cutting edge debates about discourse and cognition. This comprehensive and accessible book opens up important new ways of understanding the relation between language and cognition.
