The article belongs to the cognitive dimension of contemporary cognitive linguistics based on the idea that the processes of the world conceptualization take place in the context of a certain culture and language imparting culturally determined character to our cognition. The ethnocultural specificity of cognition has various forms of manifestation in language, the most explicit of which is metaphor because the very nature of our thinking is metaphorical and reflects the correspondence with experience which is also culture-specific. The study aims to investigate how culturally determined cognition finds its manifestation in metaphor. The main goal of the article is to point out and characterize the forms of manifestation of ethnocultural specificity of metaphor in the text. The analysis is based on a corpus of 860 metaphorical expressions obtained from 34 English-language fiction texts. The main methods of analysis are conceptual, comparative-culturological and contextual analyses. The introduction contains a short survey of theoretical works related to the interaction of language, cognition and culture and describes the way methods are applied. In the second part the author analyses the interrelations between three branches of linguistics: ethnolinguistics, linguoculturology, and cultural linguistics united on the basis of their interest in the study of language in the cultural aspect. The main body of the article presents the analysis of metaphor in the aspect of culture specific cognition which results in the identification of three forms of representing the culturally determined cognition in metaphor: 1) the degree of metaphorical density of the text and the manner of metaphorical representation from the perspective of explicitness/implicitness; 2) the specificity of conceptual spheres which serve as the source of metaphors; 3) the choice of objects of metaphorical description determined by the sociocultural conventions of a linguocultural society. By way of conclusion, the author outlines the prospects of metaphor studies in the aspect of culture specific cognition.
