Evolutionary Approach to Personality Flashcards
what is the evolutionary perspective to personality?
we are biologically programmed to engage in behaviours that facilitate survival and reproduction
goal is to pass down genes
what is natural selection
the process by which adaptive behavioura are selected
how do you study personality from the evolutionary perspective
adaptiveness of a personality trait in terms of natural selection, sexual selection, and inclusive fitness
what is inclusive fitness
traits that influence likelihood that relatives will survive
what parts of personality does inclusive fitness explain
altriusm
homosexuality
how can we assess whether traits were evolutionarily selected for?
if we see them cross-culturally, they were selected for
what is evidence for the evolutionary perspective?
universal emotion expression across cultures
why is pride an adaptive expression
occurs after success signalling the individual deserves high status
what position is most recoginized as pride?
head tilted up
puffed out chest
small smile
what is adaptive about the head tilt in pride?
looking above others
approach oriented
what is adaptive about the expanded posture in pride?
high status
draws attention
what is adaptive about the slight smile in pride?
social cohesion
individual remains within the group
what is the Burkina Faso Study?
studying if pride is a universal expression by testing recognition of pride in an isolated culture
what were the results of the Burkina Faso study
village recognized expression of pride beyond chance
pride recognition is comparable to other emotion recognition
recognition was lower than in western samples
what could have caused lower recognition of pride in the village versus in western sample
complicated procedure
previous research showed low recognition rates in preliterate cultures
what was the Olympic Judo study
photographs of olympic judo winners showed cross cultural expression of pride
shows evolutionary basis to pride
what was the paralympic judo study
photographs of blind olympic judo winners showed expresion of pride
showed innate nature of pride
what is the main cause of sex differences in adaptive measures
men fertilize externally therefore must invest in their own children
women fertilize internally therefore need to find a mate that will provide resources
what was the Buss et al. (1992) study
external fertilization should cause higher rates of sexual jealousy
internal fertilization should cause higher rates of emotional jealousy
what were the results of the Buss study?
males show higher rates of sexual jealousy cross-culturally
what is further evidence of the jealousy hypothesis
men show higher physiological arousal during imagery of sexual infidelity than emotional infidelity and vice versa
men show better memory of sexual infidelity, women show better for emotional
what is the ‘double shot’ theory
women think that for men being in love also means having sex same/vice versa for men
what effect does the double shot have on Buss’s results
no effect, sex differences in jealousy still hold
what is another way we can explain the sex differences in jealousy?
cognitive load study
distinct emotion findings
