Flashcards

Evolutionary Psychology (EP)

A way of thinking about psychology that uses the processes of natural selection to understand the design of the human mind, focusing on the adaptive problems of hunter-gatherer ancestors.

Natural Selection

The process where traits that enhance survival and reproduction are more likely to be passed down through generations.

Hunter-gatherer society

Groups of families who survived by hunting and gathering food, potentially with egalitarian social structures and division of labour.

Cognitive revolution

A significant change in human thinking, approximately 70,000 years ago.

Stone Age mind

Concept that although our bodies have evolved, our 'designed' mental processes reflect the needs of an earlier hominin hunter-gatherer society, i.e. the brains we have now are from an earlier evolutionary time.

Adaptive Problems (hunter gatherer)

Challenges faced by humans while hunting and gathering food, which natural selection shaped our brains to solve, example: judging distance.

Study Notes

Hunter-Gatherer Lifestyle and Human Evolution

  • Homo sapiens existed for 200,000 years, living in groups of families.
  • Social structures likely more egalitarian.
  • Labor division common.
  • High child mortality, but long lifespans possible.

Cognitive Revolution

  • Occurred 70,000 years ago.

Industrial and Digital Revolutions

  • Industrial revolution: 200 years ago.
  • Digital revolution: 20 years ago.

Evolution and Human Behavior

  • Genes and psychology are intimately linked.
  • Cognition, behavior, learning, and culture depend on brains.
  • Physiology and behavior depend on genes; forces that shaped our bodies also shaped our psychology.

Evolutionary Psychology (EP)

  • An approach to understanding the human mind's design.
  • A way of thinking applicable to all psychology domains.
  • Not a specific area of study.
  • The mind is a collection of information-processing mechanisms, designed by natural selection to address problems faced by hunter-gatherer ancestors.

Five Principles of Evolutionary Psychology

  1. The brain is a physical system governed by laws of chemistry and physics.
  2. Brain circuits were designed by natural selection to solve problems faced by ancestors.
  3. Most of the mind's operations are hidden from conscious awareness.
  4. Different neural circuits specialize in solving different adaptive problems.
  5. Modern minds evolved during the Stone Age.

Environment of Evolutionary Adaptedness (EEA)

  • The environment in which humans evolved.
  • Modern challenges misalign with EEA.

Mismatch Example 1: Fear

  • EEA fears (snakes, spiders) are more prevalent than modern fears (cars, guns).
  • Infants demonstrate fear responses to snakes and spiders.

Mismatch Example 2: Diet

  • Unhealthy modern diets contribute to health issues (diabetes, heart disease).
  • Cravings for high-sugar, high-fat foods.
  • EEA: limited sugar (honey, fruit) and fat (lean game).
  • Modern abundance mismatches ancestral needs.

Evolutionary Psychology of Aggression

  • Aggression is a context-dependent response to social challenges.
  • Seven evolutionary predictions regarding aggression.

Criticisms of Evolutionary Psychology

  • Methodology issues:
  • Difficulty testing backwards inferences
  • "Just-so stories"
  • Uncertainties about EEA pressures.
  • Example: gender differences in spatial reasoning.
  • Interpretations:
  • Eugenics (selective breeding)
  • Feminist concerns
  • Panglossianism (everything is perfect)
  • Naturalistic fallacy
  • Genetic determinism
  • Non-genetic explanations
  • Non-adaptive explanations.

Comparative Evolutionary Psychology

  • Addresses EP's limitations by relying less on speculation about the EEA.
  • Uses a comparative approach to study behavior origins.
  • Combines developmental, phylogenetic, and cross-cultural perspectives.

Comparative Evolutionary Psychology Methods

  1. Developmental: Early emergence suggests less reliance on social learning.
  2. Cross-cultural: Consistency suggests less social learning dependence.
  3. Cross-species: Examines if similar traits exist in other species.
  • The cultural intelligence hypothesis suggests human specialization in social cognition.
