Abstract

The recent attention given to the feedback control of human brain wave activity and the implications of such control prompts a careful analysis of this phenomenon. Particular emphasis is placed on the learned control of the alpha rhythm. A review of possible factors which might influence the density of alpha rhythms led to the differentiation of three general sources of influence: constitutional, physiological, and cognitive-attentional factors. Each of these factors is discussed as a possible mediator of the learned control of the alpha rhythm. The view is advanced that increases in alpha density during feedback training arise from a diminution of those factors which block this rhythm, and some implications of such a view are discussed. Several of the issues raised appear generalizable to the whole question of the operant control of autonomic activity.
