The study of cognitive mechanisms involved in the process of developing communicative competencies, particularly from the perspective of dialogue theory, is relevant and necessary to improve communicative activity and its effectiveness. The purpose of this research is to study the cognitive-communicative interaction in the process of dialogical communication and the cognitive conditionality of the development of communicative competencies. The methods of frame, cognitive and communicative analysis, and the analytical-synthetic method were used in the study. The main frame structures of dialogic (...) speech were considered: using one frame and similar ways of verbalization, using one frame and different ways of verbal expression, and using two frames with different thematic or semantic content. The study examined cognitive-communicative interaction in dialogic communication and the cognitive basis for developing communicative competencies. Among the important conclusions is the discovery of three primary dialogical unity frame structures. It has been found that cognitive functions affect successful communication. The study demonstrated how cognitive-communicative interaction fosters the development of communicative competencies. It was also determined that dialogue structure relates to response shifts represented as interrelated frames. The study concludes that future research should focus on studying cognitions in communicative contexts and improving foreign language communication. (shrink)
