[Psychophysiological study of the information theory of emotions using the model of positive emotion][Article in Russian]

The pattern of inter-hemisphere distribution of EEG amplitude and frequency as a function of the levels of emotional experience and motivation as well as probability of the goal achievement was studied in 20 subjects. An emotional state was evoked by simulating emotionally colored events. A modified test of Prise et al. (1985) was used to evaluate the level of motivation for the simulated event as well as the probability of goal achievement from the lengths of line segments marked by the subjects. Here we studied simulated emotion of joy. The highest correlation coefficients were observed between the awareness and alpha activity in the both hemispheres. The levels of emotional experience and motivation inversely correlated with the delta and theta activity mostly in the left hemisphere. The beta activity correlated with both the emotional and motivation levels.
