Psicologia e Sociedade, Belo Horizonte, v. 24, n. 1, p. 5-14, 2012.e- 1807-03100102-7182Ohttp://repositorio.bc.ufg.br/handle/ri/13170This article discusses the mediation concept based in Vigotsky and Adorno, reputed authors in social and educa- tional psychology. Although these authors are influenced by Marxism and focused on culture, their approaches are different. Vigotsky outlines the concept of mediation from the social-historical perspective, while Adorno analyzes the contradictions in meditation under a critical theory by the Frankfurtian. On the other hand, Vigotsky understands the mediation as cultural process by learning, based on Marxian referential and the critique of devel- opmental naturalization in the acquisition of superior functions. In Vigotski the mediation establishes a liaison, the sign, the activity and the consciousness interact socially. For Adorno, the mediation, if mystified as a result of action and subjectivity, surpasses itself a contradiction: the objectification of culture and education and in the formation; risk of establishing a false consciousness. The epistemological discussion goes beyond sociology and psychology and slips in the subject-object relation.porAcesso AbertoTeoria crítica e sociointeracionismoMediaçãoEducação e teoria críticaCritical theory and social-interactionismMediationEducation and critical theory.Artigo10.1590/S0102-71822012000100002.
