Perception features in texts of various scientific genres

The article considers the role of perception in a scientific text (article, monograph, or academic text). Special attention is paid to the representation of the phenomenon of perception, which has its origin in perception and functions in cognitive operations at the language level in a scientific text. In accordance with this, different intertextual "relations" between sources of information can be observed at different stages of perception of scientific information and the formation of scientific thought: opposition, comparison, cooperation, autonomy. The description of the process of perception in the text in the aspect of cognitive-discursive approach contributes to the knowledge of the interrelationships of linguistic and non-linguistic factors in the creation and understanding of a scientific text. Observations on the perception of author's semantic structures confirm our hypothesis about the reflection of the features of the volume of author's information, the number of features allocated to the object of knowledge, and the features of detail when describing objects of sensory and cognitive perception in scientific texts. Description of the features of reflection in the text of the process of perception in the cognitive-discursive approach contributes to the knowledge of the relationship between linguistic and extralinguistic factors of creating and understanding a scientific text.
