A General Introduction to Psychoanalysis

Psychoanalysis is a set of psychological and psychotherapeutic theories and associated techniques, originally popularised by Austrian physician Sigmund Freud and stemming partly from the clinical work of Josef Breuer and others. Since then, psychoanalysis has expanded and been revised, reformed and developed in different directions.
This was initially by Freuds colleagues and students, such as Alfred Adler and Carl Gustav Jung who went on to develop their own ideas independently from Freud. Later neo-Freudians included Erich Fromm, Karen Horney, Harry Stack Sullivan and Jacques Lacan.
The basic tenets of psychoanalysis include the following:
besides the inherited constitution of personality, a persons development is determined by events in early childhood; human attitude, mannerism, experience, and thought is largely influenced by irrational drives; irrational drives are unconscious; attempts to bring these drives into awareness meet psychological resistance in the form of defense mechanisms; conflicts between conscious and unconscious, or repressed, material can materialise in the form of mental or emotional disturbances, for example: neurosis, neurotic traits, anxiety.
