摘要:AbstractThis research is dedicated to answering the question on how the content of oppositions and implementation of dialectical thinking operations are connected at pre-school and adult age. We say that segregation of oppositions is a basic component of the structure of dialectical thinking, the one that is extremely important at the pre-school age. This ability appears to be essential for the formation and implementation of dialectical actions. With that, once formed and rigidly fixed, for example, through some specifics of the educational environment, representation of oppositions might result in development of formal logical constructions.
