Infant research observations and hypotheses have raised serious questions about previous mainstream psychoanalytic theories of earliest childhood development. In Jungian Psychotherapy and Contemporary Infant Research, Mario Jacoby looks at how these observations are relevant to psychotherapeutic and Jungian analytical practice. Using recent findings in infant research, along with practical examples from therapeutic practice, he shows how early emotional exchange processes, though becoming superimposed in adult life by rational control and various defenses, remain operative and become reactivated in situations of intimacy. Jungian Psychotherapy and Contemporary Infant Research will be of interest to both professionals and students involved in analytical psychology and psychotherapy.
