Wright & Panksepp's “SEEKING” closely resembles Freud's “libido”. SEEKING is unconditioned pleasure-seeking; it yields pleasure for its own sake. This is described as appetitive pleasure. SEEKING is stimulated by vital needs. Its biological purpose is to interest us in external objects, some of which deliver other forms of pleasure. These include consummatory pleasures, and there are a great variety of them (genital orgasm being one). The coupling of SEEKING with consummatory objects is a major task of development. Where Freud spoke of “sources,” “aims,” and “objects” of libido, Wright & Panksepp speak of “generating,” “enacting,” and “coupling” of SEEKING. Homeostatic imbalances in vital needs are the sources of SEEKING. On this view, stimulation of the mucous membranes of the oral, anal, and clitoral (phallic) regions are appetitive—not consummatory—acts. In this light, the classical erogenous zones should be described as “objects” rather than “sources” of libidinal drive.
