  1. Evolutionary Psychology

  2. Two Different Approaches to Psychology SSSM • Standard Social Science Model EP • Evolutionary Psychology

  3. Major Contrast SSSM • All is Learned • No instincts • General Processor EP • Some is innate • Some Instincts • Modularity

  4. EP Principles • Assumptions • Humans Evolved • Theory of Natural selection • Traits vary across generations • Traits that promote survival & reproduction naturally selected • Naturally Selected traits passed on to next generation • Applied to Brain and Behavior • Social Behavior as set of Adaptations • Methods and Topics

  5. Important Evolutionary Changes for Humans • Bipedalism • Frees up the hands • Climbing • Throwing • Opposable Thumbs • Dexterity • Tools • Big Brains • Language • Complex Emotions & Social Behavior • Consciousness?

  13. What about culture?

  14. Misinterpretations • Genes are not Blueprints (do not determine) • Genes more like recipes (guide) • EP is not Biological Determinism • EP is not Genes + Environment • EP IS Genes x Environment • CULTURE (Environment) matters!

  15. Applications of EP: Brains, Intelligence, Talent • Human Cognitive ability and design

  16. Spandrels

  17. Applications of EP: Brains, Intelligence, Talent • Human Cognitive ability and design • We were NOT designed to do all that we can do! • Exaptations

  18. Applications of EP: Brains, Intelligence, Talent • Human Cognitive ability and design • We were NOT designed to do all that we can do! • Exaptations • Race, Cultural Differences and Intelligence

  19. Applications of EP: Brains, Intelligence, Talent • Human Cognitive ability and design • We were NOT designed to do all that we can do! • Exaptations • Race, Cultural Differences and Intelligence • Gender

  20. Applications of EP: Brains, Intelligence, Talent • Human Cognitive ability and design • We were NOT designed to do all that we can do! • Exaptations • Race, Cultural Differences and Intelligence • Gender • Talent and Success: Geniuses made or born? • Inherited? • Learned?

  21. Success Factors • 10,000 hour rule • Context • Influence • Parents • Peers • Others • Luck!
