Lecture 5: Attraction and Partner Selection Part 2 Flashcards
Familiarity and What is Beautiful is Good Study
- Participants rated yearbook photos of people they knew, while strangers also rated the same photos.
- They examined how much variance in participants’ ratings of physical attractiveness could be explained by objective measures of physical attractiveness, liking, familiarity, and respect.
- People find those they like more physically attractive than those they don’t like
facial preferences and desired personality study
- Step 1: ask participants which personality traits they find attractive in a partner and which faces they find attractive
- Step 2: create a composite of the 15 faces most attractive to those expressing the highest desire for a trait and 15 faces attractive to those expressing the lowest desire for the trait
- Step 3: ask a new set of participants to make personality judgments based on faces
- Found that face preferences reflect the desired personality
minimal parental investment
the least amount of time, energy, and resources that a parent must expend to produce offspring
parental investment for males
minimal time investment & biological cost
parental investment for females
- A much greater investment of time & resources
- Eggs are biologically more costly than sperm
- Pregnancy, producing a placenta, lactation, extended period of infertility following childbirth.
minimal parental investment in humans
Creates a large asymmetry in the minimal parental investment of male & female members of the species -> different adaptive problems & strategies
male adaptive strategy
- Reproductive success is primarily limited by the availability of fertile mates.
- Solution: may have evolved a preference for females possessing indicators of fertility
female adaptive strategy
- Also care about genetic quality
- Invest much more, so they should be more selective than males and prefer males that can ensure the best survival of offspring
- Females may select mates based on their ability to provide resources to potential offspring
- May need to make trade-offs
- In humans, women may view such characteristics as social status, wealth, intelligence, ability, and ambition as attractive.
evidence for the evolutionary perspective of attraction
- A lot of early research relied on self-reported ratings or rankings
- Most attributes were rated similarly by men and women
- Men value physical appearance more highly, and women value characteristics related to resource acquisition
- Differences were replicated across different cultures
critiques of the evolutionary perspective of attraction
evidence that men and women have different preferences for potential mates may be due to social (rather than innate, evolved) factors. For instance, across cultures, women may find status and resources attractive in men because women have less access to status and resources.
structural powerlessness approach
- Traditional socialization practices maintain & support differences in partner selection
- The two hypotheses are not fundamentally incompatible: there is no reason we should not expect differential socialization of the young according to the evolutionary view
- In cultures where there is greater gender equality, women place less importance on a man’s status and resources
- However, gender equality does not affect the importance placed on female attractiveness
critique of partner selection studies
Paper preferences may not translate into real-life contexts
how do partner selection strategies translate to real life?
- Meta-analysis of 97 studies involving romantic evaluations of a partner (either initial attraction contexts like speed-dating or established relationships)
- Evaluation is generally more positive for more attractive partners, and partners with better earning potential
- No difference by sex
short-term vs. long-term mating strategies
- Because of the asymmetry in levels of minimal parental investment & risk, males might be more likely to pursue short-term mating strategies.
- Both males and females can shift between short-term and long-term mating strategies when conditions are suitable (i.e. benefits outweigh costs)
- Some evidence that both men and women are likely to prioritize attractiveness in short-term relationships
corollary idea behind the dual mating hypothesis
women may combine mating strategies and their mating strategy may shift with their ovulatory cycle
