Аннотация:Multidimensional color and emotional semantic spaces were previously separately studied in the ‘Vector psychophysiology’ school of thought (E.N. Sokolov, 2013). The universal spherical model was verified, but brain mechanisms of interaction between these spaces are unclear. The same 20 Russian words of two categories were used in psychophysical and EEG series (10 basic emotions and 10 basic colors). Every possible successive combination of these stimuli was presented to subject and 20*(20-1) = 380 measures of (dis)similarity were registered. In separate series were recorded, multidimensionally scaled and intercorrelated: 1. Subjective semantic differences (1–9 point scale); 2. Reaction time for deciding if the category of new stimulus changed in comparison with previous one (measuring indirect semantic differences); 3. 600-ms visual evoked potentials (16-channels EEG) to 380 abrupt changes of stimuli. 5 full 20*(20-1) matrix passes in psychophysical series and 100 passes in EEG series were conducted and 45 subjects participated in the study. Results: 1. Integral subjective space was spherical and color-emotional isomorphic (much closed to Russell's affective circumplex and Newton's color wheel simultaneously); 2. RT-matrix significantly correlated with subjective differences only in 10x10 ‘first emotion-then color’ submatrix; 3. Significant correlations of subjective differences with VEP amplitudes were found in ‘first emotion-then color’ submatrix above temporal cortex at T5 and T6 leads in N87 and P300 components and slow negative shift starting from 400 ms.
