Freud's psychoanalytic theories
The Psychopathology of Everyday Life is one of the most important books in psychology. It was written by Freud in 1901 and it laid the basis for the theory of psychoanalysis. The book contains twelve chapters on forgetting things such as names, childhood memories, mistakes, clumsiness, slips of the tongue, and determinism of the unconscious. Freud believed that there were reasons that people forget things like words, names, and memories. He also believed that mistakes in speech, now referred to as Freudian slips, were not accidents but instead the “dynamic unconscious” revealing something meaningful.
