Introduction. The article is devoted to the issues of multidisciplinary interaction in new scientific fields, which involve a wide variety of convergences, no matter how strange at first glance they may seem. One of these phenomena is the interaction of psycholinguistics and neuroeconomics.
 The goal. The article examines the transition of modern science to multidisciplinary discourse, which makes it necessary to conceptualize and possibly operationalize methods of psycholinguistics. The conceptualization of new areas of neuroeconomics, in a psycholinguistic context, presupposes a certain mental experience that includes, in addition to the processes of creating new concepts and contextual economic knowledge, also defining the role of interests, intentions, emotions in human economic activity.
 Methods. Multivariate analysis, comparative analysis, extrapolation.
 Results. It is proved that in recent decades the development of new areas of economic science, namely those related to the development of neuroeconomics, has significantly expanded the field of psycholinguistics. The production of new paradigms of economic theory, the formation of the corresponding definitions, objects requires the design and definition of them both in form and in content. It considers the need for a theoretical and orderly definition of the functional meaning of the psycholinguistic context of new definitions, the result of which can be a conceptual system for communication between specialists in various fields of science at the level of their professional understanding. It seems that the central issues in the psycholinguistic discourse of neuroeconomics have become the relationship between economics, psychology, linguistics and psycholinguistics. Such connection is undoubtedly of a multidisciplinary nature, which contributes to the deepening of the relationship between scientific thought, culture and language and became the impetus for understanding the nature of human cognition at a higher, multidisciplinary level of development of science. This is a necessary component for understanding the meanings and structure of concepts, terms and definitions, as well as communications at a higher scientific level.
 Conclusions. It is concluded that new areas of neuroeconomics such as behavioral economics, behavioral finance, emotional economics, psychological economics, have become areas of economic theory that, explicitly or implicitly, take into account the psychological characteristics of human perception and behavior in the process of economic activity. These definitions catalyze the theoretical integration of various scientific fields, and, above all, psycholinguistic science.
