The article was organized in four parts, explaining: translation problems; the relationship between the author and his time; discussion of methods for investigating concepts/giftedness; the object, material and investigation procedures developed by Sakharov in relation with Vygotsky´s work. We also discuss the criticism, replication, and impact of the functional method of double stimulation (or method of Sakharov), presented in the translation.porAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Método funcional da dupla estimulaçãoFormação de conceitosMétodo de SakharovPsicologia histórico-culturalLeonid Solomonovich Sakharov (1900-1928)Functional method of double stimulationConcept formationMethod of SakharovCultural-historical psychologyLeonid Solomonovich Sakharov (1900-1928)Artigo https://doi.org/10.1590/S1984-02922013000300014
