as theory looks at rewards & costs cn be used to explain all romantic rs all all include rewards & costs no matter what sex of couple is
also in abusive rs abuse is cost but may still be rewards - having children/receiving gifts/financial security explaining why rs is maintained
population
takes into account subjectivity of perceived rewards & costs of each individual & thus can be generalised to every type of rs
* evidence from simpson 1990?
showed p pictures of people & they had to judge their attractiveness
those who were in happy romantic rs were more likely to rate them lower than those who were not in happy romantic rs
shows that comparison level for alternatives is accurate as it demonstrates that those who are in happy romantic rs arent looking for alternatives as theyre receiving more rewards than costs so rs is maintained
X oversimplifies complex romantic relationships?
argyle suggests saying rs is similar to balance sheet as SET does - all about rewards & costs is unrealistic
rs based on feelings & human emotion - theory does not take into account
not everyone is bothered by how much reward they gain in rs some care more about other person
fails to explain why those in non profitable costly rs still maintain romantic rs
? ecological
isnt realistic explanation of rs
ungeneralisable to real life romantic experiences
may be other factors besides rewards & costs influencing formation & maintenance of rs
X not as complex as rusbults investment model?
rusbults investment model not only considers rewards & costs in rs also consideres factors that affect commitment in rs
its about maximising our rewards & doesnt explain deeper factors which can better explain how couples successfully stay together & maintain their romantic rs
X culturally biased?
its more suited to individualistic cultures than collectivist cultures
this is because in individualistic cultures people care more about their own rewards
in collectivist cultures they are more concerned with others than themselves
eg wives in collectivist culture do all houseword & childcare whilst husband goes to work to earn money - may be receiving more costs than rewards but still manage to maintain rs
? population
cannot be generalised to all cultures & explain why they still maintain rs despite having imbalances in their costs & rewards
