Nowdays the study of poetic language involves the research of the subconscious components. We have the great variety of organoleptic characteristics in these researches, but we neither possess a thesaurus to indicate suggestive phenomena, nor the tools for their analysis. It is necessary to use the tools and thesaurus of the science, which has already been developing the theory of the subconscious for more than fifty years, such as psycholinguistics and neuropsychology. Thus the concept of VAK analysis is the study of auditory, visual and kinaesthetic predicates and images (olfactory and gustatory predicates have been including in kinaesthetic system). The study of the most part (about 500) of Mandelstam’s verses according to the VAK system has allowed us to establish that in his lyrics kinesthetic predicates have dominated. The system we use to experience and to represent the world is called our primary representational system. O. Mandelstam represents the world primarily kinaesthetically. The share of kinesthetic predicates in the poetic text of O. Mandelstam is 75% which is an incredibly high. Some people actually do use two or more systems absolutely simultaneously. But poetic language of Mandelstam has represented almost pure kinesthetic code.
