Steven H. Knoblauch has been developing a strategy and theoretical perspective for using and understanding complex nonverbal experiences and communications that occur in the analytic exchange. His delineation of nonverbal communication contributes substantially to the ongoing expansion of our views of psychoanalytic interaction and theories of therapeutic action. This expansion, contributed to by many, involves the development of an interactive systems model in which verbal and nonverbal communications are viewed as actions occurring at explicit and implicit levels. In a number of Knoblauch's clinical illustrations, subsymbolic processes rapidly invoke, or are invoked by, nonverbal or imagistic symbolic processing and meaning-making as well, often followed by verbal symbolizing processing. Subsymbolic and verbal and imagistic symbolic processing, intrinsic modes of organizing data, probably continually influence one another bidirectionally in a flowing feedback loop.
