Psychoanalysis has a long and complicated history in relation to the subjective experience of the infant. While initial efforts to account for what went on in the mind of infants was largely driven from within various psychoanalytic theoretical schools, the emergence of the developmental sciences introduced new challenges and opportunities for psychoanalytic developmental theorists. These tensions were most captured by the conflictual relationship between psychoanalysis and attachment theory. Since this time, some prominent analysts/developmentalists have made efforts to meaningfully integrate quality developmental research and theory with psychoanalytic theory. This course will survey the literature produced in this vein, with particular attention to the output of the Boston Process Change Study Group, a small group of practicing analysts, developmentalists, and analytic theorist who believed that knowledge of recent developmental studies and dynamic systems theory can be used to understand and model change processes in psychoanalytic therapy. The focus of this course will be on the subjective experience of the infant and the development of a sense of self, with our last class dedicated to considering implications for adult treatment.
