Relationships in Development is both a clinical resource and a vital intellectual history--a clear account of how research about infancy transforms psychotherapy practice and an authoritative survey of the place of child development in psychoanalysis.It updates developmental psychoanalysis by integrating it with trauma theory, neuroscience, nonlinear dynamic systems theories, and infant mental health work. "Executive summaries" of attachment, intersubjectivity, and "the relational baby" are offered, leading to an open and flexible approach to psychodynamic therapy in varied socioeconomic and cultural situations. This Classic Edition includes a new introduction assessing the current state of developmental thinking in the psychotherapy world.Relationships in Development will appeal to psychoanalysts, psychoanalytic psychotherapists, and graduate students in psychology, social work, and psychotherapy, as well as to all those interested in psychotherapy and child development.
