The paper, presenting research within the scope of cognitive linguistics, concerns the problem of conceptualization of meanings by language users and terminological difficulties with the selection of terms for describing language aspects of human cognition. The aim is to present the referential fields of terms, such as schemas/frames, idealized cognitive models, mental spaces, as well as the cognitive mechanisms which hinder clear distinctions between them. The main goal of the author is an attempt to prove the thesis that the psychology reality principle to the largest extent satisfies the description of mental representation and processing of meanings in the categories of cognitive domains, mental spaces and conceptualizations.
