Human mating psych 1

  1. Extramarital affair rate

    Conflict in mating
    30 to 50 percent of all couples

    Conflict in mating is the norm and not the exception
  2. Sexual Selection
    Evolutionary characteristics because of reproductive benefits
  3. Intrasexual Competition
    Members of the same sex compete with eachother

    Greater strength, intelligence, etc
  4. Intersexual Competition
    Looking for a certain characteristic in a mate

    (peahens look for peacocks with shiny, plump feathers)

    the peacocks with dull feathers will not survive
  5. Evolutionary Psychology
    Discovering underlying psychological mechanisms that explain evolution
  6. Sexual Strategies
    Ways that humans attract a mate through adaptations, etc

    Most of these acts are carried out unconsciously
  7. An evolutionary sign to combat infidelity
  8. Vigilance and Violence
    Responses to sexual jealousy
  9. Strategic Interference
    Sexual strategy of one sex can trip up the sexual strategy adopted by the other sex

    Ex: How long men and women wait to have sex

    There is a conflict because these two strategies because men cannot fulfill their short term wishes without interfering with a woman's long term goals
  10. Naturalistic Fallacy
    Whatever exists should exist

    (contradicted by viruses, plagues, etc)

    Just because they exist in nature doesn't mean that they should exist
  11. Antinaturalistic Fallacy
    Occurs when we see ourselves through the lens of utopian visions of what we want people to be
  12. Evolutionary Psychology
    Attempts to discern evolutionary forces behind the design of the human mind

    Uses evolutionary theory to make predictions about behavior and cognition
  13. Selection Pressures
    Determine which mutations will be selected for, and which mutations will be selected against

    Ex: a mutation that helps turn sunlight into energy will be selected in the population, not a gene that makes an organism allergic to sunlight
  14. Adaptation
    A biological trait that becomes widespread in the population through the process of natural selection because it solves an adaptive problem

    • The solution to a specific adaptive problem iscalled the adaptation’s “function.
    • ”• Example: Bones made out of calcium solve the adaptive problem of how to hold a body up and in shape. Calcium was selected for because it’s biologically available and has a good strength/weight balance.
  15. Byproduct
    A trait that is a consequence of an adaptation, but has not been selected itself

    Ex: The whiteness of bones from calcium
  16. Noise
    The result of random genetic mutation that has no functional significance at all

    Ex: flecks of color in eyes, the specific patterns of fingerprints
