1. Structural Theory
2. Libido (Drive) Theory
3. Topographical Theory of mind
4. Theory of Narcissism

• Freud's structural theory postulated the existence of the id, ego, and superego.
• Id:
  • First to develop
    
  • Completely unconscious
    
  • Contains all drives
    
  • Ruled by pleasure principle
    
  • No awareness of reality
• Ego:
  • Second structure to develop
    
  • Operates on reality principle
    
  • Mediates conflict among id, ego, and superego
    
  • Provides reality testing
    
  • Monitors quality of interpersonal relations
    
  • Provides synthesis and coordination
    
  • Carries out primary autonomous functions
    
  • Defends against anxiety
• Suoerego
  • Third structure to develop
    
  • Self-criticism based on moral values
    
  • Self-punishment
    
  • Self-praise based on ego ideal
    
  • Most functions are unconscious
• Conflict is the main concept of structural theory.

• Libido theory assumes that biological “needs” (drives) fuel behavior.
• The aim of behavior is to gratify the drive.
• Drives are either sexual or aggressive in nature.
• The libido theory explains that the sexual instinct plays an etiological role in the neuroses and that sexual stimulation exerts a predominant force (which is called libido) on mental activity throughout life.
• The discharge of libido is experienced as pleasure.

• Topographical theory explains three regions of mental functioning or systems of the mind exist as defined by their relationship to conscious thought:
  • the conscious,
  • preconscious, and
  • unconscious.
• Conscious level of mind refers to the portion of mental activity and content that is directly available to immediate perception.
• Preconscious level of mind refers to mental content and processes that are not conscious but can be readily accessed by the direction of attention.
• Unconscious level of mind refers to a set of mental processes and content that operates outside conscious awareness.

• Narcissism refers to excessive love or admiration of oneself or self-love.
• The term also refers to the erotic pleasure derived from contemplation or admiration of one's own body or self, especially as a fixation on or a regression to an infantile stage of development.
• Freud explained his theory of narcissism in his seminal paper "On Narcissism: An Introduction" (Freud, 1914 ).
• Freud explains primary and secondary narcissisms, which emerge in normal human development.
• Primary narcissism refers to a the state in which  the desire and energy that drives one’s instinct to survive.
• Secondary narcissism occurs when the libido withdraws from objects outside the self, above all the mother, producing a relationship to social reality that includes the potential for megalomania.
• Problems in the transition from one to the other can lead to pathological narcissistic disorders in adulthood.
