Psych Exam Review: Theories of Dreaming

Introduction

• Presenter: Michael Corayer
• Focus: Introduction to three theories of dreaming
• Purpose: To briefly describe main concepts of each theory

Freudian Theory of Dreams

• Concepts:
  • Dreams represent contents of the unconscious
  • Hidden wishes, fears, desires are expressed in dreams
• Dream Content:
  • Manifest Content: Actual dream events
  • Latent Content: Hidden meaning behind dreams
• Interpretation:
  • Discover unconscious contents by analyzing dreams
  • Problems with Interpretation:
    • Some dreams seem direct, no hidden meaning
    • Interpretation is subjective; may reveal more about the analyst

Activation-Synthesis Model (Hobson & McCarley, 1977)

• Process:
  • Activation: Random activation of different brain regions
  • Synthesis: Brain tries to make sense of random activation
• Characteristics:
  • Accounts for bizarre, illogical nature of dreams
  • Interpretation may reveal aspects of the dreamer’s mind
• Criticism:
  • Question of randomness in brain activation

Information-Processing Theory

• Concept:
  • Dreams are not random; they are related to memory processing
  • Processes during REM:
    • Memory consolidation
    • Sifting through experiences for meaning
• Mechanisms:
  • Strengthening new neural connections (long-term potentiation)
  • Maintenance of old connections
• Day Residue:
  • Study: Robert Stickgold’s Tetris experiment
  • Dreaming about activities related to problem-solving
  • Memory consolidation and problem-solving during REM

Common Themes in Dreams

• Personal yet common:
  • Dreams reflect personal experiences but share universal themes
  • Common dreams: losing teeth, running from predators
• Evolutionary Perspective:
  • Dreams simulate experiences for future preparation
  • Not exact future events but preparation for potential problems
