EEG Frequency-Amplitude Characteristics of Successful Recognition of Emotion in Speech

Psychophysiological mechanisms of perception of speech emotional expression were I studied. Comparison of EEG between 2 extreme groups (with high and low indexes of) identification of emotional intonation) revealed significant differences in frequency-amplitude characteristics of brain electrical activity. Two general conclusions can be made from the data obtained. Firstly, the subjects with low identification rates show a higher brain activation and reactivity both during the emotion identification task and at rest as compared to the subjects with high identification rates. Secondly, the data reveal specific activation within the right posterior temporal cortex. Therefore, high initial cortical activation and more pronounced EEG reactivity impede recognition of emotion in speech.
