Psychoanalytic Theory of Personality

Introduction to Psychoanalytic Theory

  • The psychoanalytic theory, primarily associated with Sigmund Freud, posits that childhood experiences and unconscious desires significantly influence behavior.
  • Freud was originally a physician and neurologist, not a psychologist. His interest in medical psychopathology began after studying hypnosis in Paris in 1885.

Key Concepts of the Theory

  • A central concept is the "unconscious," which encompasses memories, beliefs, urges, drives, and instincts that are not always accessible to awareness.
  • Libido is introduced as a natural energy source driving mental mechanisms; fixation at various psychosexual development stages can lead to lifelong conflicts affecting adult personality.

Psychosexual Development Stages

  • Fixation at specific psychosexual stages predicts adult personality traits; for instance, someone fixated at the oral stage may exhibit characteristics like excessive talkativeness or smoking habits.

Structure of the Mind

  • Freud's model divides the mind into three structures:
  • Id: Unconscious part demanding immediate gratification (developed post-birth).
  • Ego: Mediates between id's demands and reality; seeks long-term gratification (partly conscious).
  • Superego: Develops around age four; acts as moral compass or conscience.

Conflict Between Mental Structures

  • Conflicts arise when libidinal impulses are over-gratified or under-gratified during psychosexual stages. This leads to anxiety stemming from competition among id, ego, and superego.
