Socio-cultural psychology is widely known as a theory and research field that stresses the determinant role of social interaction and culture in the development of the higher psychological functions. This chapter presents a view of the human subject that avoided dualism (mind-body, individual-social, physical-symbolic) and was capable of bridging the gap between the basic psychological processes and the higher processes involving consciousness and meaning. It describes the reorganization of dynamic systems as a key concept for the description and explanation of perception and movement. The main claim is that the kind of explanation including self-organization and temporal dynamics applied to the development of perception and action may be useful for the explanation of how socialization and enculturation processes develop. The chapter explores the concept of re-mediation, and the practices from it derived, which are one of the privileged arenas where basic psychological processes and socio-cultural phenomena have historically intersected.
