Relationships Flashcards
Evolutionary psychology
Explains behaviour in terms of its function and adaptiveness. The extent to which the behaviour enhances the survival and reproduction of the individual genes
Natural selection
- the gradual process by which nature selects the forms most fit to survive and reproduce in a given environment
- individuals with characteristics that are most suited to the environment and are likely to survive and reproduce
Sexual selection argues…
That if a characteristic increases the chances of reproduction, it will be adaptive because the male will have more offspring
Anisogamy
Humans are anisogamous- they produce gamers of different sizes. In these species, the female invests more energy in reproduction than the male so it leads to two different types of sexual selection. Intersexual and intrasexual (explained on other cards)
Inter-sexual selection
Where one sex chooses traits they desire in the other sex- quality strategy (selective)
Intrasexual selection
Competition between same sex- quantity strategy
Travers (1972)
Females make a greater investment of time, commitment and resources before, during and after birth
Fisher’s (1930) sexy sons hypothesis
A woman chooses a man because he has a characteristic which will be more desirable to women therefore making the son ‘sexy’
Zahavi’s (1975) handicap hypothesis
Women chooses handicapped men because him overcoming this problems shows genetic superiority
Male characteristics
- 12-15% larger than females
- deeper voice
- facial hair
Female characteristics
- breasts
- hips
- smooth skin
Male strategies
- Physical size matters for men so they may use the gym
- behaviourally- aggression could work
- compete by producing larger testicles, bigger ejaculation and faster swimming sperm
Sneak copulation
- males mate with females other than their partner if given the opportunity as it increases reproductive chances
- women benefit as wider genetic diversity increases survival chances
- women can also gain by having a rich male, while copulating with a genetically fit stud
Cartwright (2000)
- men and women prefer symmetrical faces. Equates to reproductive fitness. Symmetrical breasts are more fertile, women with symmetrical partners have more orgasms
- supports the sexy sons hypothesis
Buss (1989) ‘what women want’
Conducted large cross cultural study into human mating preferences. 10,000 people, 37 cultures. Found consistent gender diferentes
Evaluation of evolutionary psychology
- explanations are oversimplified. It cannot explain couples choosing not to have children as it assumes there is desire to reproduce as well as heterosexuality
- Clark and Hatfield completed a study where attractive confederates would ask men and women to mate. ‘Found women mate wisely, men mate widely’
- Singh (1993+2002) ‘curves in the right places’ waist to hip ratio is a determinant of attractiveness. Optimum is 0.7 WHR
- fertile dancers earned more tips

Self disclosure
- involves revealing personal information about yourself
- romantic partners reveal more about their true selves as the relationship develops
- these revelations strengthen the relationship of used appropriately
Social penetration theory (Altman and Taylor, 1973)
- relationships are a gradual process of regalo my your inner self to someone
- in romantic relationships it involves reciprocal exchange of information between partners. Leads to a deep understanding of others lives. Breadth and depth
- onion metaphor. Low risk early. High risk information as relationship progresses
Reciprocity of self disclosure (Reis and shaver, 1988)
- there tends to be a balance of self disclosure in successful romantic relationships, as well as breadth and depth
- after disclosing information, you want your partner to respond in a rewarding way with understanding and empathy
- increases intimacy and deepens the relationship
Factors influencing the relationship between disclosure and attraction
- appropriateness of the disclosure. Can be inappropriate
- attributions for the disclosure. Reasons why we believe people are disclosing are important
- gender differences. Women better communicator es
- content for the disclosure. Higher disclosure too early is turn off
Evaluation of self disclosure
- supported by research studies. Lau ren ceau (2005) found that self disclosure was linked to higher levels of intimacy in long term married couples. Reverse was also true. Supported by social penetration theory
- real life application- people who want to improve communication in their relationships can use self disclosure
- individual differences, different individuals would have different needs for levels for intimacy in a relationship
- too reductionist- unlikely attraction is only due to the self disclosure shown
- correlation research doesn’t meant that it is a cause
Physical attractiveness
An important factor in the formation of romantic relationships. The term usually applies to how appealing we find a persons face. There is a general agreement within and across cultures about what is considered physically true.
Shackle Ford and Larson (1977)
Found people with symmetrical faces are more attractive as they have an honest signal of genetic fitness. People are attracted to baby face features. Triggers and instinct of protecting and caring
Mcnutly (2008)
Physical attractiveness continues to be an important feature of a relationship after marriage, for at least several years
The halo effect- Dion (1972)
- ‘what is beautiful is good’
- physically attractive people are rated as kind
- beliefs that food looking people will have such characteristics makes them more attractive to us so we behave more positively towards them
Walster (1966)
People choose romantic partners who are roughly of similar physical attractiveness to each other. To do this we must make a realistic judgement of our own value.
