Urgent problems in a new branch of knowledge - the psychology of reflection, the history of development and the present-day state of its basic lines, their philosophical-methodological and scientific-applied grounds are analyzed. Proceeding from the systems approach to a complex study of creativity the authors single out four types of reflection: intellectual, personality-bound, communicative, and cooperative. It is shown that interaction between them is a prerequisite for appearance of new psychological formations. Main models of reflection mechanisms are described - in informational-cybernetic terms, in meta-activity terms, and in personality-meaning terms. Some possibilities of application of the knowledge concerning types and models of reflection in educational psychology and in human factors engineering are considered.
