Relevance of the study is due to the need for more detailed researching of categorization of synonymous ranges of names of basic emotions by the energy characteristics “intensity” and “power”.

Objective. Construction of circular categorical scales of the energy characteristics “intensity” and “power” in the spherical 6-dimensional model of emotions and analysis of language organization of the semantic structure of perception of their names.

Methods. Psychophysical method of revealing mechanisms for structuring semantics in linguistic consciousness based on a neuropsychological spherical model of vector coding of emotional-cognitive operations of detection and differentiation of signals E.N. Sokolov. Method of direct supra-threshold measurement of the subjective value of semantic differences between the names of emotions. Method of multidimensional scaling ALSCAL of subjective differences. The method of modeling the subjective semantic structure in the form of a spherical 6-dimensional Euclidean space. Method of measuring subjective characteristics in the form of circular scales in 2-dimensional subspaces. Methods for grouping and segmention lexical units based on the threshold values of their semantic differences.

The experiment involved 152 people aged 19 to 22 years.

Results. Circular scales of energy characteristics of «intensity» and «power» of emotions are constructed in the spherical 6-dimensional model of the semantic structure of the names of emotions by the combination in pairs of distinctive features-axes “inhibition/excitation” – “variability/stability” and “closeness /openness” – “acceptance/rejection” respectively. 8 and 10 categorical groups of synonyms are highlighted on the “intensity” and “power” scales with gradual values “norm” – “deviation from the norm”. The categories of “intensity” and “power”, expressing a high degree of manifestation of emotions, prevail. The general content for all members of each of the synonymous series on the “intensity” and “power” scales is indicated through their enumeration.

Conclusions. The mechanism of semantic grouping of the names of emotions into categorical classes and segmentation them among themselves has a uniform character based on the computation of differences and belongs to the energy characteristics “intensity” and “power” of emotions as well as the qualitative characteristic of the tone.
