N2 - Emotion is a multicomponent reaction of organism to relevant stimuli and situations. The Influence ofconsciously perceived affective sensory stimuli on a human physiology and behavior is well studiedtoday, but little is known about the effect of unconsciously perceived emotional stimuli. Also there isunsolved question about the fundamental differences in physiological and behavioral reactions toemotional stimuli perceived either consciously or unconsciously.The purpose of current research was to carry out the comparative study of objective physiologicalchanges in response to emotions of different valence provoked by consciously and unconsciously 21perceived emotional stimuli. Precisely we analyzed dynamics of physiological measures (EEG, ECG,SGR, pneumogram and the latency of sensorimotor reaction) to acoustic stimuli with different emotionalcontents.It was received that both consciously and unconsciously perceived affective stimuli provoke definitechanges in frontal asymmetry (FAS) ratio of EEG, which correspond to the valence of the experiencedemotion. However in most cases these changes to unconsciously perceived stimuli started earlier, butwere less stable than in response to consciously perceived stimuli. Activation of sympathetic nervoussystem and arousal occurs in both cases of sensory perception of emotional acoustic stimuli. In case ofunconscious perception the complex of vegetative reactions (according to an ECG, SGR, respiration rate)were more pronounced , but didn‟t depend on the valence of the provoked emotional state as compare toconscious perception. Consciously perceived negative emotional sounds led to an increase in the time ofsensorimotor reaction and number of the missed reactions. The revealed differences in dynamics ofphysiological indexes to unconsciously and consciously perceived emotional acoustic stimuli improvedunderstanding of the common principles of physiological mechanisms of emotional processes.
