In 1884 he worked with Breuer which started his investigation, development and birth of psychoanalysis. Freud believed he was able to demonstrate the normal development of the sexual drive present in infants. Then on the basis of an examination of dreams and bungling acts, he claims he was able to determine the resistance of the unconscious that influences everyday thoughts and actions. Freud observed the essential relationship between the psychoanalyst and the patient in what he called transference, establishing its central role in the analytic process. Freud still exerts influence in psychology, psychiatry and psychotherapy, as well as modern Western thought with the common idea of a ”Freudian slip.” He continues to generate extensive and highly contested debate concerning psychoanalysis’s therapeutic efficacy, scientific status, and role. ver menos
