ABSTRACT
Sensory-motor ideas have appeared in several guises. They have been identified with the indexical component of the speech-thought relationship; with "images of movement" that guide articulation; with the basis of syntagma; and with elements of meaning that are semiotically extended to contact semantic content at other levels. All of these manifestations of sensory-motor ideas arise from the unique epistemology ofthe sensory-motor level of representation. Sensory-motor ideas alone exist simultaneously in the realm of action and the realm of meaning. It is this dual existence that gives them their central position in the speech-thought relationship. The sensorymotor meaning domain has direct access to the control of speech articulation.
