title: Correlates of alpha, beta and theta wave production.
abstract: Studied the correlations of alpha, beta and theta time densities with psychological and psychophysiological variables in a psychiatric population (N = 76). The correlations of the EEG variables with measures of adjustment were small and barely exceeded chance expectations. Alpha and beta were correlated positively with pain threshold, while beta was related inversely to blood pressure. Theta was correlated positively with blood pressure and negatively with pulse rate. The implications of these findings for EEG biofeedback treatment were discussed.
