The article relates to the problem of the nature and structure of human language capacity. The author addresses the fundamental questions of the place of the language and the role it plays among other cognitive faculties, such as perception, thinking, memory, attitude etc. She first presents a multidisciplinary character of the research programs dealing with selected specific and unique attributes of the human cognitive system, its structure and function. Current models of the human mind are typically based on divergent methodological, epistemological, and ontological assumptions. How useful they prove to be comes with their heuristic value, which testifies the inspiration that they bring about theoretically and empirically. The author scrutinizes the modular models of the mind and argues that they constitute the basis for the further methodological discussion on human capacity of the language placed in the context of mono-, bi-, and multilingualism. The author opts for modular conceptions due to their theoretical relevance, originality, and convergence with the latest findings in cognitive neuroscience. The latter is the reason why she considers the cognitive and the neurobiological aspects of language capacity to be complementary to each other. Any and all attempts at relating cognitive neuroscience to modularity theories are, then, said to be interesting and have practical implications. So do neurolinguistic experiments and models of the mind that stem from both neurobiological and modular considerations.
