Resting levels of alpha and the Eysenck Personality Inventory.

The number of microvolt seconds of alpha rhythm emitted during a five-minute period were collected for 30 male and 30 female subjects. This measure of alpha abundance was then compared in subjects who scored high and in those who scored low on the E and N scales of the Eysenck Personality Inventory. Subjects who scored low on the E scale tended to have a significantly greater number of microvolt seconds of alpha than did subjects who scored high on the scale. No differentiation on the basis of emitted alpha was possible for subjects scoring high and low on the N scale.
