ten years later in Critical Discursive Psychology (2002), but by this time he is pessimistic about the critical potential of a purely discursive approach. He prefers the term 'discursive practice'. His book on methodology, Qualitative Psychology: Introducing Radical Research (2005) includes a new version of discourse analysis that attempts to break down the divisions between the researcher and those they study. Critical responses and commentaries on the impact of Ian Parker’s work on discourse analysis have often focused on what is seen as a reification of ‘discourse’: his conceptual work on discourse has been criticised on this basis from a traditional social psychological position (e.g., Abrams and Hogg, 1990 ) and from a 'discursive' position (e.g., Potter et al., 1990; Potter & Edwards, 1999 ). Critical commentaries on his work on discourse analysis were included in his book Critical Discursive Psychology in 2002, and in the second edition of that book in 2015. Marxist psychology Parker employed Marxist arguments in his first book, and that book on the 'crisis' ends with a discussion of 'transitional demands' that borrow from Trotskyist politics (and these demands are designed to start from what it is reasonable to ask for but in such a way as to lead to a questioning of oppression). A co-edited book, Psychology and Society: Contradiction and Coexistence (1996) is explicitly concerned with Marxist approaches to psychology, and a note indicates that the original title was to be Psychology and Marxism. All the contributors to this book are Marxists, but using a variety of different psychological theories (and Parker’s chapter is on Trotsky and psychoanalysis). Discussion of Marxist psychology is scattered throughout Parker’s work, and he defines himself as a Marxist, and supporter of the Fourth International. There is a reflection on this in the opening chapter by him of Critical Discursive Psychology, and Marxist ideas are outlined (alongside psychoanalysis, post-structuralism and feminism) in a paper 'Discursive resources in the Discourse Unit' written for the Discourse Unit, a research group which he founded with Erica Burman. Recent interviews indicate that feminist arguments have become more important to Parker, and that Marxism itself may not provide a complete true theory (or alternative to psychology). The discipline of psychology is now treated as an ongoing process of 'psychologisation' operating within institutions suffused with the power to define and manage individual behaviour and experience. This argument is outlined in the book Revolution in
