Digitally analyzed EEG recordings were obtained from the left occipital to left high central areas of 76 adult subjects. EEG frequency, amplitude and an EEG index were compared with scores on the Self-description Questionnaire. Results supported the hypothesis that a difference existed in the EEG alpha of persons scoring below 24 on the questionnaire (O group) and those who scored 24 and above (H group). It was demonstrated that the group means were significant (p.06) with respect to EEG amplitude and index but not EEG frequency. Implications of the established EEG-personality relationship were discussed.
