Relations between the speech semantics and the sphere of speech application are considered. The experimentally obtained data enables the author to differentiate between the notion of meaning and the notion of sense (as a system of transformations of meaning functionally determined by the latter). Different orders of sense (information) derived from meaning by different functional structures are analyzed, and a conclusion is made about the necessity to postulate existence of functionally different types of communication. Study of systems of the meaning transformation functionally determined by the given text and indicative of the type of sense objectively functioning in the system of communication comprizes the subject-matter of the functional psychosemantics.
