His writing has provided compass points for researchers searching for alternatives to ‘mainstream’ psychology in the English-speaking world (that is, mainstream psychology that is based on laboratory-experimental studies that reduce behavior to individual mental processes). The three critical traditions Parker has promoted are ‘discursive analysis’, ‘Marxist psychology’ and ‘psychoanalysis’. Each of these traditions is adapted by him to encourage an attention to ideology and power, and this modification has given rise to fierce debates, not only from mainstream psychologists but also from other ‘critical psychologists’. Parker moves in his writing from one focus to another, and it seems as if he is not content with any particular tradition of research, using each of the different critical traditions to throw the others into question.
