This article is the result of many readings, studies, reflections and debates of a research group that takes Historical-Cultural Psychology as its theoretical and methodological basis. Its nature is theoretical, in that it results from the writings of the authors of this approach and some of his researchers to present understandings of the major concepts of Vygotski, its most important theoretician. It aims to gather and discuss the key concepts of this author, which are scattered throughout his work, in addition to introducing their interpretation and application possibilities in the study and practice on human development. The complexity of the work of the author demands countless studies and the commitment to the dialectical and complex aspect of his theories. We therefore seek to demonstrate in this text the plausibility of his theory to explain psychological phenomena, providing contributions and suggestions for actions that can support the practice of psychologists in institutional settings, especially schools.
