9 - Moral & Evolutionary Psychology Flashcards
what are the 3 premises of Darwinian evolution?
- individuals of a species show variation in traits (behavioural, psychological etc).
- Some variation is heritable.
- Some traits provide benefits in terms of survival & reproduction (adaptation).
Therefore, certain adaptive traits are selected for over the course of generations (selected by survival & reproduction).
What is the definition & assumptions of evolutionary psychology?
Definition; the application of evolutionary theorising to u/stand human psychology & behaviour.
Assumptions:
- mind is composed of a collection of evolved mechanisms.
- Adaptations (selections).
- Domain-specific.
- Designed to solve various recurrent problems, e.g. disease avoidance, mate selection/retention, kin care.
What is the problem of altruism? What was Dawkin’s argument?
If evolution tailors organisms to behave in ways that facilitate success fo reproduction, doesn’t this mean organisms will be selfish?
Dawkins;
- take a gene’s-eye’-view.
- genes vs individuals (different perspective)
- genes try to make host behave in ways that facilitate gene proliferation.
- If altruistic behaviour helps person survive/reproduce, then altruism is evolutionarily-relevant.
What is inclusive fitness (Hamilton, 1964)? What is the difference between direct & indirect fitness?
The capacity for genetic info to spread in the population.
- Direct; number of offspring produced
- Indirect; increasing classical fitness of kin/relatives.
Key point; Not all kin are equal, kids more than
How do ground squirrels alarm calls (Sherman, 1977, 1981) provide evidence of helping kin at cost to self?
Squirrels emit alarm calls in response to predators, localising themselves at a cost, to benefit others. However, they’re more likely to call in the presence of sisters. aunts, & nieces.
Describe the findings by Essock-Vitale & McGuire (1985) in their Helping episodes for LA Women study.
Percentage of helping episodes were highest amongst close relatives, and decreases as relation decreased (less related, cousins etc).
What was the single largest predictor of child abuse and homicide (Daly & Wilson, 1988)?
Presence of a step-parent in the home resulted in 40-100 x higher rate compared to both genetic parents.
Describe Laham et al.’s (2005) Grandparental certainty/investment study.
Takeaway 1: Mother’s-mother highest investing, Father’s-father lowest. Investment is related to degrees of relatedness.
Takeaway 2: When there a more investment outlets for grandparents (more certainty), diluted effect.
List some challenges & criticism of evolutionary psychology.
- Pan-adaptationism; “everything’s an adaptation (unfounded crit).
- Genetic determinism; no nurture (unfounded crit).
- Implications for morality; naturalistic fallacy (unfounded crit) “because something is true it is moral”.
What is evolutionary psychology’s value?
- Metatheory; provides an organising framework for social and all psychology.
- The function of psych mechanisms.
- Unpacks distal (ultimate) causes; why not just the how. Why is sweet rewarding & shock not?
What is morality?
code of conduct or set of rules pertaining to right, good, wrong, bad etc.
Describe Turiel et al.’s (1987) moral/conventional task?
Children were presented with various scenarios that represent violations of rules; violence, boys wearing dresses, talking out of turn in class…
Then asked; is violation wrong/serious, punishable, authority dependent, and explanation of why it’s wrong.
What is the signature moral response?
SMR;
- serious, wrong, bad
- punishable
- authority independent.
- universal (general in scope).
- some harm/rights infringed.
Key feature: if HARM (justice or rights) then SMR.
How did Haidt, Holler, & Dias (1993) challenge the harm violation aspect of the signature moral response?
Some people judge certain transgressions, that do not include harm, as immoral, via authority independent & universal aspects.
What are Shweder et al.’s (1997) 3 ethics of morality?
- autonomy; individual freedom/rights violation.
- community; person fails to carry out duties within community/social hierarchy.
- Divinity/Purity; sin, the natural order of things, spiritual defilement.
