Abstract:  People's emotion is a kind of comprehensive state whether objective things meet people own needs is closely associated with the physiological signal. The subjects POMS (profile of moods states) scales and the EEG (electroencephalogram) signals of resting state at the same period are collected to study the correlation between them. Wavelet transform is used to preprocess the original EEG signal. EMD (empirical mode decomposition) method is adopted to decompose the denoised EEG into IMFs (intrinsic mode functions). Volatility index is extracted from the IMFs as a feature. The EEG features and POMS scales are analyzed by Pearson correlation analysis. The POMS scale and EEG signals are recorded and analyzed in 8 subjects for a period of 7 days. The experiment shows that there exists a strong correlation between the EEG signal and the related components of the personal emotion state.

Key words: profile of moods states (POMS) scale, electroencephalogram (EEG), empirical mode decomposition (EMD), Pearson correlation analysis
