According to Münsterberg's Action Theory the intensity of the sensation depends upon the strength of the incoming current. Its quality depends upon the position or location of this current in its particular neurone. The vividness depends upon the "openness" or "closedness" of the neurone conditioning the _outgoing current_. And finally to the feeling-tone shall correspond the local difference of this discharge in outgoing currents. For instance, the pleasant feelings have, related to them, central outgoing paths which lead to approach, and thus to the continuation of the stimulus, and the unpleasant feelings have related to them in turn central neurones which lead to withdrawal or escape, and thus to the breaking-up of the stimulus. Our empirical data gathered from the experiments above reported demand not so much a modification as an elaboration of this theory. The _tridimensionality_ of the feeling-tone itself must be physiologically described. We must conceive the feeling-tone itself as possessed of its own vividness, intensity, and quality. It seems clear indeed that any explanation of the affective or feeling-character of experience must be sought somewhere in the outgoing currents from the motor region. This alone will serve to account for the inevitable volitional or "intent" aspect which invariably accompanies feeling, and I think may serve to account also for the organic or necessarily coördinating or functioning aspect required by some writers who so stoutly object to "barren atomistic or structural" psychological explanations. The Action Theory might then be specialized in the following way:
