Why is theory important to the practice of critical research? Why are debates over the role of discourse in psychology crucial to the way we interpret texts? This book explores crucial questions to do with discourse, subjectivity, postmodernism, psychoanalysis and Marxist theory in psychology. Key critical theoretical resources are described and assessed and a series of polemics is staged, bringing together writers who have helped shape critical work in psychology. The book also introduces key issues in critical discursive research in psychology, and outlines the historical context in the discipline for the emergence of qualitative debates. It also sets out methodological steps for critical readings of texts. The book makes available a set of debates at the intersection of theoretical intervention and political critique, and it maps the shape of critical discursive research for the twenty-first century.
