This paper presents human stress pattern for alpha and beta waves obtained from EEG Power Spectrum analysis. The EEG stress evaluation conducted between human Cohen's PSS-10 Stress Questionnaires with EEG Power Spectrum. The EEG recording had been carried out among 86 volunteers as soon as they finished answering the stress questionnaires. The scores from questionnaires were computed immediately right after sample answering the questionnaires using GUI. Hence, the total stress score is used to figure out its relationship with the EEG Power Spectrum in determining the left or right brain activation during stress presence. The results of the study showed that there is EEG Human Stress Pattern for Low Stress and High Stress which is associated with Alpha and Beta Waves.
