Palatovska O. Russian complex sentence in cognitive-discursive interpretation (based on the material of oral scientific and professional communication)

The aim of this dissertation is to study Russian complex sentences of various formal organization in terms of their storage in the mental grammar of modern speakers and mechanisms of integration into oral scientific and professional discourse, which is generated without reliance on written text, as well as establishing a collection of prototypes that organize these syntactic units in an oral scientific monologue. The object of research is a Russian complex sentence. Research methods – general scientific, cognitive-discursive, traditional linguistic, psycholinguistic, corpus and quantitative, which varied and combined with each other depending on the stage of work and research problems. The theoretical significance of the dissertation is that the study is a promising stage in the development of cognitive-discursive theory of syntax, it will serve as a methodological basis for new cognitive-discursive studies of both complex sentences and other language units. The practical significance of the work involves the use of its materials in the teaching of theoretical grammar of the Russian language (syntax), general linguistics, special courses in cognitive linguistics, psycholinguistics, a practical course in Russian for foreign citizens. The dissertation materials can be used in experimental psychology and psycholinguistics, in formation of speech behavior of public speakers, in writing textbooks and practical grammars on the Russian language, as well as in the practice of intercultural communication and translation studies. The study led to the following effective innovations: identified and described universal mechanisms for embedding complex sentences in spontaneous scientific and professional discourse by the recipient of the message, as well as cognitive strategies for segmenting discourse into syntactic units by the addressee in terms of time- limited natural auditory perception; the discursive status of a complex sentence in an oral scientific monologue is determined from the cognitive positions of the speaker and the listener, in particular, research proved that both participants of communicative interaction single out a sentence as an intermediate unit of discourse based on its formal organization; clarified regularities of recoding the original oral scientific message for another (written) information transmission channel; the collection of prototypic means of syntactic connection of parts of a complex sentence, fixed in the consciousness of modern Russian language speakers; established is the relationship between the formal organization of the prototype construction and the type of discourse that it presents in external expression; theoretically substantiated and tested method of complex cognitive-discursive study of complex sentences in oral scientific and professional communication.
