In Psychology, over a century, different concepts have been developed. Vygotsky's theory of concepts is traditionally framed in the first one - the classical view, the only one in his time. However, this framework is questioned by the authors of this article. Based on the analysis of the literature, the aim of this study is to compare the design of Vygotsky with different psychological views on concepts, identifying similarities and differences between them. Through this analysis it was possible to identify the theory of Vygotsky relevant aspects of the different ways to understand the concepts, which indicates that the author was ahead of his time, anticipating questions that would only be discussed after decades.
