P3 Section B (Relationships) Flashcards
What is sexual selection
Sexual selection is the evolutionary process of selecting a mating partner who displays advantageous behaviour in human reproduction
What behaviour can be advantageous in human reproduction but disadvantage otherwise
Aggression can be advantageous in human reproduction but disadvantageous otherwise as it shows protection
What is anisogamy
Anisogamy is the form of sexual reproduction between the two opposite gametes - sperm and egg cells.
What is a consequence of anisogamy
A consequence of anisogamy is that there is a plentiful fertile male population, but fertile females are rare.
What are anisogamy’s two mating strategies
Anisogamy’s two mating strategies are inter- sexual selection and intra-sexual selection
What is inter-sexual selection
Inter-sexual selection is the strategy where mainly females have preferences for members of the opposite sex who have desirable qualities.
What is intra-sexual selection
Intra-sexual selection is the strategy whereby mainly males compete with each other to mate with a female.
What do females desire in a male
Females desire in a male: height, strength and physical attractiveness
What do males desire in a female
Males desire in a female: signs of fertility such as small waist-hip ratio and smallness
Summary of inter-sexual selection
Summary of inter-sexual selection: quality over quantity
Summary of intra-sexual selection
Summary of intra-sexual selection: quantity over quality
What is a psychological consequence of inter-sexual selection
A psychological consequence of inter-sexual selection is that females need to be very choosy as their offspring must have features of the mate
What is a psychological consequence of intra-sexual selection
A psychological consequence of intra-sexual selection is that males have a minimal post-coital responsibility as they are biologically driven by mating with as many fertile females
What is a behavioural consequence of intra-sexual selection
A behavioural consequence of intra-sexual selection is that males prefer youth such as youthful facial features and also fertility such as certain waist-hip ratio.
What is Fisher’s Sexy Sons Hypothesis
Fisher’s Sexy Sons Hypothesis is the idea that females prefer males who have desirable traits like height as this will be inherited by their son increasing the likelihood that they will then mate.
What was Buss’ method to support preferences relating to anisogamy
Buss’ method to support preferences relating to anisogamy was a survey of over 10,000 adults across 33 countries asking questions relating to their partner preference
What did Buss find to support preferences relating to anisogamy
Buss found to support preferences relating to anisogamy that females placed value on resource-related characteristics like finances and men placed value on reproductive capacity like good looks and youthfulness showing the sex differences in mating strategies
What was Clark and Hatfield’s method to support inter-sexual selection
Clark and Hatfield’s method to support inter-sexual selection was asking male and female students “would you go to bed with me?”
How do Clark and Hatfield support inter-sexual selection
Clark and Hatfield support inter-sexual selection by female/male confederates asking students “would you sleep with me” and found that 0% of females said said yes and 75% of males said yes - showing female choosiness when selecting a partner
How does Bereckzei say sexual selection has changed
Bereckzei says social changes have made women’s male preferences far less resource orientated as more women are financially independent
How does Singh support males preference of waist hip ratio
Singh supports males preference of waist hip ratio by finding that average liking is 0.7 to be deemed as fertile and not pregnant
What is a negative of Singhs WHR research
A negative of Singhs WHR research is that it was only tested on Asian men so can’t be applied universally
What did Anderson found about male preferences across countries
Anderson found that males in countries where food supply is scarce prefer heavier women but in countries where food supply is stable, men prefer slimmer women
What is self-disclosure
Self-disclosure is an act of revealing personal details like intimate thoughts, feelings and experiences.
How did Collins and Miller support self-disclosure in attraction
Collins and Miller supported self-disclosure in attraction as found people preferred those who reveal more information about themselves
What was Sprecher’s disclosure study procedure
Sprecher’s disclosure study procedure was pairing 156 participants and they engaged in a self-disclosure task on Skype
What did Sprecher’s disclosure study find
Sprecher’s disclosure study found that pairs in reciprocal condition liked closeness and enjoyed the interaction more than those in non-reciprocal dyads, so reciprocal disclosure more attractive
How does Reis and Shaver support Sprecher
Reis and Shaver support Sprecher by thinking relationship deepens by reciprocity - which also increases intimacy
How did Sprecher and Hendrick support self-disclosure
Sprecher and Hendrick supported self-disclosure by finding strong correlation between satisfaction and self-disclosure in heterosexual couples
How did Hass and Stratford support self-disclosure in relationships
Hass and Stratford supported self-disclosure by finding 57% of gay men/women said open and honest self-disclosure was the reason for a deep and committed relationship
How did Tang find cultural differences in self-disclosure in relationships
Tang found cultural differences in self-disclosure by reviewing literature to find men and women in individualistic cultures would disclose more sexual feelings than those in China - so self-disclosure can’t be generalised from the western cultures
How did Shackelford and Larsen say physical attractiveness affected attraction (symmetrical)
Shackelford and Larsen said physical attractiveness affected attraction as found people with symmetrical faces are rated more attractive as it is a sign of genetic fitness and also people are more attracted to neotenous features as they trigger a caring instinct
What is the halo effect
The halo effect is the tendency to to assign positive qualities to an attractive person like Palmer and Peterson finding better looking people were rated better politically
Who made the Matching Hypothesis
Walster and Walster made the matching hypothesis
What is the matching hypothesis
The matching hypothesis is the idea that individuals seek a partner whose desirability equals their own as it will maximise chances of a relationships initialising
What was Walster’s findings to test matching hypothesis
Walster’s findings were that people responded more positively to attractive people regardless of whether they matched in intelligence or personality - so not supporting the matching hypothesis
What was Walster’s repeated method to test matching hypothesis
Walsters repeated method to test matching hypothesis was having participants choose their own partners before the dance so it was more like real life as they could match with someone who they believed had same physical attractiveness
