Book excerpt: In this book, Wilma Bucci applies her skills as a cognitive psychologist and researcher to the fields of psychoanalysis and psychotherapy, opening up new avenues for understanding the underlying processes that facilitate therapeutic communication and change. Grounded in research geared to understanding and demonstrating the clinical process (rather than "outcome") of analytic inquiry and therapeutic dialogue, Bucci’s multiple code theory offers clinicians, researchers, trainers, and students new perspectives on the essential, often unlanguaged, foundations of the psychotherapeutic endeavour.
