Psychoanalysis is a set of theories and therapeutic techniques related to the study of the unconscious mind, which together form a method of treatment for mental-health disorders. The peculiarities of the speech development of senior preschool age saw as his “most significant work”, appeared in November 1899. Psychoanalysis is a controversial discipline and its validity as a science is contested.
Nonetheless, it remains a strong influence within psychiatry, more so in some quarters than others. Sigmund Freud, who formulated his own theory of psychoanalysis in Vienna in the 1890s. Freud was a neurologist trying to find an effective treatment for patients with neurotic or hysterical symptoms. Josef Breuer, which was generally seen as the birth of psychoanalysis. Around the same time Freud attempted to develop a neuro-physiological theory of unconscious mental mechanisms, which he soon gave up. It remained unpublished in his lifetime. Freud’s essay “L’hérédité et l’étiologie des névroses” which was written and published in French in 1896.
In 1896 Freud also published his so-called seduction theory which proposed that the preconditions for hysterical symptoms are sexual excitations in infancy, and he claimed to have uncovered repressed memories of incidents of sexual abuse for all his current patients. By 1899, Freud had theorised that dreams had symbolic significance, and generally were specific to the dreamer. Freud formulated his second psychological theory— which hypothesises that the unconscious has or is a “primary process” consisting of symbolic and condensed thoughts, and a “secondary process” of logical, conscious thoughts. Freud turned his attention to the subject of narcissism.
Still using an energic system, Freud characterized the difference between energy directed at the self versus energy directed at others, called cathexis. Three years later, he summarised the ideas of id, ego, and superego in The Ego and the Id. In the book, he revised the whole theory of mental functioning, now considering that repression was only one of many defense mechanisms, and that it occurred to reduce anxiety. Hence, Freud characterised repression as both a cause and a result of anxiety. By 1936 the “Principle of Multiple Function” was clarified by Robert Waelder. He widened the formulation that psychological symptoms were caused by and relieved conflict simultaneously.
