Among the basic theories of psychoanalysis, the parts related to psychological counseling and psychotherapy mainly include: unconsciousness and depression theory, sexual psychological development theory, personality composition theory and psychopathology theory of neurosis.
Unconsciousness has two meanings: first, people can't realize the real reasons and motives of some of their actions; Second, there is a potential psychological activity under people's conscious consciousness.
Freud's unconsciousness is a kind of dynamic unconsciousness. He thinks that there is a conflict between motivation, desire and repression in human unconsciousness, which is dynamic rather than static. When the concept of unconsciousness was formed, Freud pointed out that there are two kinds of unconsciousness, one is the deep unconsciousness called "repressed unconsciousness"; One is shallow and close to consciousness, which is called "pre-consciousness" or "potential unconsciousness"
Freud believed that people have two instincts: self instinct and sexual instinct.
Psychological structure theory, also known as personality structure theory, is Freud's later theoretical contribution. According to this theory, personality structure includes three stages: ego, id and superego. Id: It is the most primitive, fuzzy and difficult part of personality. It is blind excitement with no purpose in the life system, including all kinds of desires and conflicts. It is an energy reserve with no purpose at all, and it is the motive force for seeking satisfaction from instinct. Ego: Ego is on the surface of the original ego, between pre-consciousness and unconsciousness. Reflect rationality and caution in personality structure. In addition to the general functions of perception, memory, thinking and action, the ego is mainly to feel the reality and deal with the relationship between individuals and reality. Superego: Also known as ideal ego, it is the supervising and criticizing institution in personality and the representative of all moral reasons. The main function is to distinguish good from evil according to the social moral concept to which an individual belongs, as a criterion for self-action. It represents ideals and conscience.
