Evolutionary Social Psychology Flashcards
Darwin’s theory of evolution
1- Vary in traits (adaptations) 2- inherit traits 3- prevalent traits promote reproduction and survival (natural selection)
evolution and learning/environment
predisposed to certain developmental outcomes
Fixed action pattern
Hardwired behaviour which once triggered are run to completion
20th century explained human behaviour through
learning, culture/context, rationality
When did evolutionary social psychology occur
70/80
What are the costs of group living
exploitation, threat to safety and disease transmission
what is the mechanism that generates adaptive behaviour
functionally specialised (domain-specific) mechanisms
What is the proximate explanation
mechanisms
What is the ultimate explanation
function and evolutionary origins
what is the pregnancy sickness example?
function- heighten senses
ultimate- avoid toxins / protect embryos (Profet, 1992)
Heredity
adaptive mechanisms most humas process influenced by environment
Heritability
proportion of variation explained by genetic variation
kin selection theory
altruistic behaviour towards close genetic relative
reciprocal altruism
benifit potential recipients (punish cheats)
Parental investment theory
one sex choosier so other more competeivive
