Kirchoff and Davies (1962) suggested that there are certain limitingfactors that affect the choice of partners. We only become attracted to those who passthrough a series offilters
Field of avaialbles
all the people who are available to us to start a relationship with
field of desirables
the subset of peoplewithin the field of availables that we’d actually like to start a relationship with.
social demography
Socialvariables such as age, socialbackground, ethnicity, religion, etc. determine the likelihood of individualsmeeting and socialising which will in turn influence the likelihood of a relationships being formed.
We are also morelikely to preferpotentialpartners we share a social demography with as they are moresimilar to us and we sharemore in common with them in terms of norms, attitudes and experiences.
similarity in attitudes
Psychological variables to do with sharedbeliefs and attitudes are the bestpredictor of a relationship becoming stable and these people are seen as moreattractive to us. Self Disclosure is essential at this stage to ensurepartnersreally do sharegenuinesimilarity
complementarity
Rather than having the sametraits and attitudes, people are attracted to those that possesstraits which the otherlacks, thus supporting their emotional needs.
Both partners being the same may lead to conflict, therefore this is important for the success of long termrelationships
Kirchoff and Davies (1962)
studied couples who had beentogether for more/less than 18months. Over sevenmonths, couples completedquestionnairesbased on their views and attitudes which were thencompared for similarities.
found that similarityofattitudes was the mostimportantfactor in the group who had been together for less than 18months (short-term relationships)
found that complementarity was the mostimportantfactor in long term relationships . This supports the filtertheorysuggestion of the importance of attitudes and complementary attraction for romantic partners.
limitation of Kirchoff + Davies study
the study may not be generalisable to populationsoutsideyoung, Americanstudents (culturebias)
lackstemporalvalidity
Some stages of this model may now be seen as lessrelevant, for example as modernsociety is much moremulticultural and interconnected (by things such as the internet) than in the 1960s, we may now see social demography as less of a barrier to a relationship. This may lead to the criticism that the theory lackstemporal validity
Davis and Rusbult (2001) and Andersonetal. (2003)
investigating the second and thirdlevels of the filtertheory look at correlation which cannot easily explaincausality
bothfound that people become moresimilar in differentways the moretime that they spend in a relationshiptogether. So it may be that the relationshipleads to an alignment of attitudes, and also a greater complementarity as couples assigneachotherroles
(strength) linked explanation
By including benefits of the partner in providing for emotionalneeds and complementing potential failings, this links to socialexchangetheories of relationships more than just a basicphysicalexplanation of attraction
