The purpose of the paper is to show the need to extend the framework and the subject of research in the contemporary developmental psychology. Some fundamental issues related to the problem of the nature and mechanisms of human development are discussed. In its context the General Model of Development is postulated. There is assumed that comprehension of human development requires: (a) description and explanation of all kinds of developmental changes, both short- and long-term, progressive and regressive; (b) to take into account other kinds of time then chronological (age of life) as a markers of developmental changes (i.e. biological, social, psychological age); (c) to overcome the limitations of conventional interactionism dominated in considerations about the genesis of psychic manifestations in different aspects of life.
