Various communication studies have revealed the existence of a "preverbal" stage of communication consisting of centers within the brain that exists in an innate form or a form preprogrammed for future information acquired from the environment through experience (socialization). Such centers serve to prepare the individual for communication at the intrapersonal and interpersonal levels. These ideas about the material within the centers and their "location" are predicated on knowledge gained from contributions made by behaviorial, psychoanalytic, and neurophysiological approaches to communication study. The preverbal model operates on drives associated with both internal and external stimuli. That is, the information stored in the preverbal centers can act in concert with that in other centers to provide an internal motivation or in concert with that in external centers to produce more or less predictable communication. The level of prediction, however, is mediated by the style or dominance of one hemisphere of the brain over the other and the control of one evolutionary level of the brain over other levels. Whether such centers are scientifically verifiable will be determined in the future. For the present, it is sufficient to suggest that the preverbal stage of communication does exist and that it affects the communication of both intrapersonal and interpersonal communication.
