The idea that individual differences in personality arise because they are unrelated to any
adaptive needs is the: Genetic noise hypothesis
Life history theory concerns: Each individual has finite time and energy to solve adaptive
problems (survive, reproduce, make sure your offspring reproduce).how you allocate
your energy reflects your life-history strategy
Costly signaling theory
Balancing selection
In the animal example of life history theory, the young, bold big horn males’ reproductive
life history strategy was to: Mating success
Promidcuous mating system
Strong competition for access to females
Strong intra-sexual selection
In the Blue-Headed Wrasse, when the alpha male is killed: the largest female turns into a
male over night
A protogynous sequential hermaphrodite species:
Primary form is female
Secondary males form harems
The primary males reproduce by spreading sperm randomly in the water or
sneaking into the harem and mating when the blue-headed guy’s not looking
The top four qualities most desired in a mate are:
Dependable character
Emotional stability and maturity
Pleasing disposition
Education and intelligence
The following is one of several reasons for costly signaling
Survival ( solicit investment from one’s parents, get other genetically-related
individuals to invest in you, get people ion your social network to invest in you)
Reproduction (helps to attract a mate)
The “Question Reality” bumper sticker is a costly signal for which of the Big Five?
Openness
Going to college is a costly signal for which of the Big Five? Openness
The “Coexist” bumper sticker is a costly signal for which of the Big Five? Agreeableness
Parasite load is associated with: openness
Being a sociopath is an example of: frequency dependent selection
Balancing selection
Genetic variation is maintained because different levels on a trait dimension are favored,
or are adaptive, indifferent environmental conditions
Reproductive strategies in which a person wants to have many children are called:
r Strategy
