Book excerpt: Although psychoanalytic concepts underlie most forms of psychotherapy practiced today, the basic Freudian theory of mind the metapsychology does not mesh with current scientific views in psychology and related fields. As a result, despite its many strengths, psychoanalysis has been relegated to the periphery by clinicians and researchers alike. Filling a significant void, this book from cognitive scientist and psychoanalytic researcher Wilma Bucci proposes a new model of psychological organization that integrates psychoanalytic theory with the investigation of mental processes. Solidly rooted in current cognitive science, multiple code theory recognizes the focus on meanings and motives that is intrinsic to psychoanalytic clinical work. The theory points to parallel functions underlying free association and dreams, as well as conceptual development in children and creative work in sciences and the arts, and provides a strong foundation for empirical research on the psychoanalytic treatment process.
