Outline what is meant by human reproductive behaviour
Any behaviour which relates to opportunities to reproduce and pass on our genes
What is meant by sexual selection
An evolutionary basis for partner preference
Define anisogamy
The difference between male and female gametes
Define inter sexual selection
Selection between the sexes. Strategies one gender uses to select their partner
What do women seek in a male partner according to inter sexual selection?
Women seek indicators of socioeconomic status
What do men prioritise in their partner according to inter sexual selection?
Mens prioritise physical appearance which are cues to a woman’s reproductive value
What are the evaluation points for inter sexual selection? AO3
+ supporting evidence (BUSS)
- social desirability
+ supporting evidence (Clark and Hatfield)
- Face validity
Evaluate Buss’ research as supporting evidence for inter sexual selection AO3
P: a strength of inter sexual selection is that the here is supporting evidence for the theory
E: for example, Buss conducted a meta analysis including 37 cultures and analysed 10,000 responses to questionnaires asking respondents which factors were important in a sexual partner. Buss found that men valued attractiveness more than women did and that women valued economic status highly
E: this is a strength because evidence provided by Buss supports the theory of inter sexual selection
Explain social desirability as a counterpoint to Buss’ study AO3
P: a limitation of Buss’ study is that social desirability may have affected female responses
E: for example, females may be less likely to report finding physical attributes attractive as it may be deemed shalow
E: this is a limitation as for atleast the female respondents the findings may not be totally valid
Evaluate Clark and Hatfield’s study as supporting evidence for intersexual selection AO3
P: a strength of inter sexual selection is that there is supporting evidence
E: for example, Clark and Hatfield sent attractive male and female psychology students around the campus of a university. Asking other students if they would sleep with them tonight. 0% of females agreed but 75% of males agreed
E: this is a strength because it supports female choosiness when selecting a mate and that males opt for a different strategy to ensure reproductive success
Explain how inter sexual selection has high face validity AO3
P: a strength of inter sexual selection is that it has high face validity
E: for example, the existence of trophy wives and females using cosmetic surgery to appear younger is real world support of the validity of inter sexual selection. Furthermore, men often exaggerate their resources to persuade females to mate with them
E: this is a strength as it provides real world evidence in support of the validity of gender differences in mate choice
Explain intra sexual selection as a theory of partner preference
Intrasexual selection refers to strategies within a sex, for example competition between males to be selected by a female. This leads to gender dimorphism
Define gender dimorphism
Different genders looking different due to intrasexual selection, as males are competing, larger animals are at an advantage so males are often 15% larger than females
Evaluate research from Buss as a strength of intrasexual selection AO3
P: a strength of intersexual selection is that there is supporting evidence
E: for example, Buss found that men are significantly more likely than women to make threats of violence towards others who were perceived to have made sexual advances towards their mate. In contrast, females often used verbal aggression to target and reduce the attractiveness of a competitor in the eye of the male
E: this is a strength as it supports the theory of intra sexual selection and males competing
What are the 2 general evaluation points for partner preferences? AO3
- cannot explain homosexual relationships
- deterministic
Evaluate not being able to explain homosexual preferences as a limitation of evolutionary explanations of partner preference? AO3
P: a limitation of sexual selection theory is that it cannot explain partner preferences in homosexual relationships since reproduction isn’t the main aim.
E: for example, Lawson looked at personal ads placed by heterosexual and homosexual men and women describing what they were looking for and offering. They found that preferences of homosexual men and women differ just as they do in heterosexual men and women
E: this is a limitation as men still prioritise physical appearance and women prioritise resources despite not planning on having children
Evaluate evolutionary explanations as being deterministic AO3
P: a limitation of evolutionary explanations of human reproductive behaviour is that it is deterministic
E: for example, if human reproductive behaviour was driven by purely evolutionary considerations then they would be highly predictable. However, with the widespread use of contraception and couples choosing not to have children suggests we have more control over our own behaviour than suggested by the evolutionary explanation.
Gender difference may stem from cultural traditions rather than evolution such as women being denied economic and political powers might account for their tendency to rely on the security and economic resources provided by men
E: this is a limitation as it shows that mate preferences are the outcome of not only evolutionary influences but cultural too
Define parental investment
Any investment made by a parent that increases the chances of the offspring surviving
Do men have high parental investment and why?
Men have low parental investment since they have low paternity confidence and can produce a vast number of offspring in their lifetime.
It makes reproductive sense to mate with as many females as possible to ensure his genes are passed on to
Do females have high parental investment and why?
Females have high parental investment since they are 100% sure the child is theirs and can only have a maximum ammount of offspring in their lifetime.
So it makes evolutionary sense for women to be choosy since they should only mate with a male who would protect her offspring and pass on her genes
What are the 2 evaluation points for parental investment AO3
+ supporting research
- not relevant in today society
Evaluate supporting research of parental investment AO3
P: a strength of the parental investment explanation is that there is supporting research
E: for example, Clark and Hatfield sent an attractive male and female across a university and approached students asking if they would go to bed with them tonight. 75% of men agreed to the request but 0% of the females agreed
E: this is a strength since it supports the idea that women are more choosy than men because of their high investment. While men are more laidback when it comes to casual sex
Define self disclosure
The sharing of personal information about the self which leads to increased attraction
Explain social penetration theory
Focuses on the gradual process of revealing your inner self involving the reciprocal exchange of information. One partner reveals personal information, signalling they trust the other person. For the relationship to develop then this must be reciprocated
As each partner discloses more and more they penetrate more into each others lives
