Reproductive success

Sexual selection
Competition for mates between members of the same sec which has an impact on the evolution of certain facial and bodily features

Altman and Taylor social penetration theory
Breadth and depth of self disclosure
Breadth: at the start of relationship we disclose a lot of superficial information
Depth: as the relationship develops self-disclosure becomes deeper and higher risk
Reciprocity of self disclosure
Reis and shaver
Once you’ve disclosed something that reveals your true self hopefully partner will respond in a way that is with understanding, empathy and their own feelings
3 theories of self disclosure

Evaluation of self disclosure
+ research (Spencer and Hendrick)
+ practical application (hass and Stafford)
- reductionist (other explanations of attractiveness like physical)
-cause and effect
The halo effect
Helo effect is where people that are deemed more attractive tend to benefit from favourable perceptions from society
For example an attractive person is more likely to be acquitted of a crime, deemed more trustworthy and sociable impact as physical attractiveness is what we see first in a person
where people that are deemed more attractive tend to benefit from favourable perceptions from society
Halo effect
Matching hypothesis
The theory that people will seek partners of similar attractiveness to themselves. This means we need to have a realistic judgement of how attractive we are in the first instance.
Additionally if one feels their partner is more attractive there is likely going to be fears they will leave
Hence implying our choice of partner isn’t most attractive but a compromise
Evaluation of physical attractiveness
+research (palmer and peterson) (gunnell and ceci)
- highly subjective
+ research to support matching hypothesis (Murstein)
-Cause and effect
Filter theory (name)
Kerchoff and Davies
Filter theory
Our choices of mates are limited by several factors and they filter down potential mates available to us.
1.Social demography
2. Similarity in attitudes
3.complementarity
Filter theory 1. Social demography
Factors that influence the likelihood of you meeting a partner in the first place. Your more likely to meet someone that you’re physically close too
Filter theory 2. Similarity in attitudes
Partners will often share important beliefs and values
Filter theory 3. Complementarity
The ability to meet each others needs and compliment each others personality traits
Evaluation of filter theory
-lacks temporal validity (dating apps)
+research (Peter winch)
-cause and effect (couples end up complementing eachother because of the time they spend together
Social exchange theory (name)
Thibault and Kelly
Social exchange theory summary
Proposes that relationships involve the exchange of resources. Relationships are based on profit someone perceives they will gain from the relationships
Once the relationship starts ‘costing’ more than it benefits the relationship is likely to fail and break down
Social exchange theory (Comparison level)
the comparison on the current relationship with often past relationships using them as a guide
Social exchange theory (comparison level for alternatives)
Other personal relationships are looked at. Eg if you’re feeling someone else or considering others. If they’re judged to offer more benefits the relationship will likely break up.
4 relationship development stages (Social Exchange)
Sampling
Bargaining
Commitment
Institutionalisation
Sampling stage (SET)
Rewards and costs are assessed in a number of relationships
Bargaining stage (SET)
The couple negotiates the relationship and agrees the rewards and costs. Marking the start of the relationship where partners start to exchange
Commitment stage (SET)
The couple settles into the relationship and the exchange of reward becomes fairly predictable. Stability also increases as rewards increase and costs decrease
Institutionalisation stage (SET)
Norms and expectations are firmly established. The couple fully settle down
Evaluations for Social Excange theory
+ Rusbult and Zembradt
+ practical applications (fixing relationships)
- theoretical flaw (costs are less important when forming but more important when breaking down)
-negative view on humans (selfish)
Equity theory name
Walster
Equity theory overview
Based on fairness between partners. Individuals will become dissatisfied if they feel they are suffering from inequity (over or under benefitting)
Underbeneffitting can lead to feelings of anger, hostility
Overbeneffiting can lead to can guilt and shame
Perceived equity
Inequity doesn’t necessarily mean inequality.
Because a person holds subjective views on the relative inputs and outputs of themselves and partner.
Profit (equity theory)
Benefits of the relationships - the costs
Distribution (equity)
Trade-offs and compensations negotiated
Dissatisfaction (equity)
Less unfairness leads to less dissatisfaction
Realignment (equity)
Attempts made to realign equity
Evaluations of equity theory
+Dainton
+Yum (transcends cultural differences)
-cause issues (people only think about fairness when the relationship is already in trouble)
Commitment (relationships)
The likelihood that someone will persist in an existing relationship, this is influenced by high satisfaction and investment
Rusbults model of investments
Satisfaction + Alternatives + investments
Commitment
=
Future stay or leave decision
