Objective
to concretely illustrate the role of language mediation in the constitution of the subject’s higher mental functions, seeking to articulate authors of a cultural-historical background, such as Vygotsky, along with the methodological perspective of Heloisa Marinho, a Brazilian researcher who focused on language and was a pioneering contributor to the area of child development.
Methodology
based on the study of the relationship between the oral and graphic mode of communication (MARINHO; WERNER,1982) and using Werner’s (2012) observation script, a microgenetic analysis of graphic activity (WERNER,1999,2001) was conducted with a sample of 3000 children on a two-year-old boy from the university nursery.
Result
it was possible to illustrate the way in which, in the setting of adult-child and child-child interactions, qualitative transformations occur in psychological functions in which semiotic mediation has a foundational and constitutional role.
