APA Dictionary of Psychology

one of Sigmund Freud’s earliest and most celebrated cases, reported in Fragment of an Analysis of a Case of Hysteria (1905). The study of this woman’s multiple symptoms (headaches, loss of speech, suicidal thoughts, amnesic episodes) contributed to his theory of repression and the use of dream analysis as an analytic tool. It was also the first case in which he suggested the concept of transference.
