Theory and methodology

Jean Piaget’s so-called biological perspective is often paired with the viewpoint of Lev Vygotsky when we speak of learning in humans. Both authors acknowledged the active role of children in the construction of knowledge. However, they differ in that, unlike Piaget, Vygotsky believed that the assimilation of new information does not have to wait for an appropriate level of development but must, on the contrary, produce that development through instruction; thus, cooperation between teacher and student promotes the development of higher psychological functions. The present research presents proof that school instruction is instrumental in this process. Samples of adults who had acquired distinct levels of schooling (from illiterates to university students) are differentiated experimentally through the use of four Piagetian cognitive problem-solving tasks created for adolescents and adults. The present research suggests that instructional level is the distinctive factor in the development of those problem-solving capacities that implicate higher psychological functions.

Lev Vygotsky’s statement on the development of the higher psychological functions— from the interpsychological form to the intrapsychological form—is discussed in the article. I describe the changing of Vygotsky’s interest from nonverbal to verbal communication and his emphasis on verbal communication as an only kind of interpsychological function. I then analyze works that show the importance of nonverbal communication in this process. I raise the questions of what an interpsychological function is and who is its “owner.” I argue that immediate response to the behavior (verbal and nonverbal) of another person is a basis for the psychological functions of a child, and this basis continues to influence processes in later stages of human development, including adulthood. Thus, interpsychological function in the development of the child is inevitably connected with some kind of passivity in reactions to social stimulation.

One of the most important and sharply discussed aspects of scientific knowledge is the problem of the possibility for practical applications and results. The application of psychological knowledge in different types of schooling, training, and instruction is a representative illustration of that problem’s current state. The aims of this paper are (1) to consider the possibilities and difficulties of such an application, (2) to analyze the reasons for both success and failure, and (3) to try to work out a path toward the construction of an applied theory to bridge the gap between psychological theory (in particular, learning and developmental psychology) and instructional practice. Specifically, this article considers practical applications of the fundamental psychological theory of Planned, Stage-by-Stage Formation of Mental Actions, or the PSFMA theory, by P. Galperin as the target case.
