Lecture 13 Flashcards
What is Evolution?
Change over time in frequency with which genes, and characteristics they produces, occur within an interbreeding population
What do Mutations do?
Continually introduce new genetic variation
What are Adaptations?
Changes that promotes survival/reproduction
What allows Adaptations to become more frequent in the population?
Natural selection
What do domain specific adaptation?
Solve particular problems (e.x. mate section, finding safe food, avoiding particular environmental hazards)
What are Broad Adaptations?
General, multi purpose, and versatile (e.x. language, logical reasoning)
How does the environment help?
It provides input to evolutionary mechanisms that predispose infants to learn particular things
What does Evolutionary Psychology ask?
How behaviour and tendencies have evolved in response to environmental demands
How much variance in personality is attributed to genotype differences?
40-50%
What does the Five factor model of personality suggest about genotype?
Genotype contributes to 40-50% of the difference in personality
What does the Genetic contribution to personalities imply?
There is an evolutionary role in shaping personality
What is the Basis for the Evolutionary Personality theory?
There is an evolutionary role in shaping personality
Why do some extremes for personality get selected by evolutionary mechanisms?
Because there is always some natural variation and some traits are adaptive in different environments
What do different environments exert?
Different evolutionary/selection pressures. And different environment are always changing
What do many different characteristics and behaviours have to potential to become?
Adaptive or maladaptive in different times/places
