  • Investment model
    • Rusbult et al: developed SET further
      • Couples stay together even when benefits outweigh the costs- so must be other factors
    • satisfaction
      • positive vs negative emotions experienced and how much one partner satisfies the others needs
    • comparison with alterntives
      • refers to if there is a more attractive alternative an individual might end their current relationship
    • investment
      • refers to anything that a person has to put into a relationship that would be lost if they left
      • can include possessions, children, time and energy
      • intrinsic: things we put directly into the relationship- effort, money, self disclosure
        • extrinsic: things that are brought to peoples life through the relationship e.g. children, friends and memories
      • intrinsic and extrinsic investmetns can be lsot- they conclude bigger the investment=more likely to stay
    • maintenance mechanisms
      • accommodation: acting in a way to promote relationships rather than keeping tally
      • willingness to sacrifice: putting their interests first
      • forgiveness: willingness to forgive mistakes both minor and serious
      • positive illusions: being unrealistically positive about a partner
      • ridiculing alternatives: minimising advantages of alternatives and viewing them in a negative light
    • research examining
      • research support: Beals and Peplau longitudinal study using married couples over 18 months
        • Stability of relationships positively correlated with commitment shown
      • Rhahgan& Axsom- studied group of women. all 3 factors identified influence their decision to stay with their partner
      • Le& Agneew- meta-analysis of 52 studies, 11,000 ppts. discovered that the factors contributed to commitment and this was a defining feature of  long lasting relationship
    • Evaluation
      • research support
      • explains why people remain in abusive relationships.
        • Rusbult& maltz studied battered women. more likely to return to abusive partner if they felt like they had invested something
          • can be applied to wide range of experiences which increases ecological validity
      • majority of research is correlational. this limits the predictive validity s it cannot say what type or *** much investment leads to a long term relationship
      • evidence from interviews and questionnaires- unreliable and subjective. but due to the values being subjective this is appropraite
    • issues and debates
      • oversimplifiedGoodfiend&Agnew: not just what we bring but also plans for the future that count as investments. shows that investment is complex
      • no culture bias: Le&Agnew- meta analysis found support across individualist and collectivist cultures. also valid in different subgroups
      • support found across cultures which suggests the need for investment and commitment is developed through natural selection
        • E.g. parents who are committed mean higher chance of ensuring child's survival thus passing on genes
          • supports nature nurture
