An attempt is made to define the subject-matter of the psychology of management, and to show the specificity of its basic notions. Particular attention is given to the problem of individual socialization in the process of organized common work. Three basic aspects of the problem are considered: socialization of individual work, socialization of individual needs, socialization of behavior in managerial situations. Particular tasks which arise before managerial psychologists in the corresponding context are analyzed. The principal idea of the suggested solution of the socialization problem consists in the rejection of the "immediacy postulate" and its substitution with the postulate of organized common activity as an intermediate link.
