This theory suggests
that in choosing a mate,
we first reject people
who are too dissimilar to
us, then choose the
person most similar to
us from those who are
left.
The most important
factors to be similar on
are personality and
attitude. In
relationships where
partners hold different
views, attitude
alignment often
occurs.
Explanations of why similarity is important
strengthen the theory. It has been suggested
that we like people similar to ourselves because
we assume they are more likely to like us too, so
chances of rejection are lessened. Furthermore,
the reward-need satisfaction theory suggests
that holding similar attitudes would be
rewarding.
In a lab experiment,
participants read
descriptions of a stranger
and were asked to rate
liking of them. The
participants rated liking as
higher when they were
more similar to them.
(However - IDA - lab study
and related problems).
A competing hypothesis suggests that
dissimilarity is more important than
similarity (the dissimilarity-repulsion
hypothesis). One study found that
participants were first attracted based on
similarity, then became less attracted to the
other person as dissimilarities were
discovered. This weakens similarity theory
as it suggests that the steps suggested are
in the wrong order.
There are the same
issues as RNS theory
when it comes to
cultural and gender
differences (IDA).
Reward-Need Satisfaction Theory
This theory is based on
the idea that people have
unmet needs, for example,
the need for
companionship, and when
other people meet those
needs, it is rewarding.
Mutual attraction occurs
when both individuals
meet the other's needs.
Classical and Operant conditioning
are involved, classical conditioning
because we associate people with a
pleasant experience or feeling,
leading to conditioned pleasant
feelings when that person is
encountered. Operant conditioning
is involved because if a person
creates positive feelings for us by
sharing our views, etc, they become
a reinforcer to those feelings and
we are motivated to spend more
time with them.
Participants were evaluated on a creative task, then asked to rate
how much they liked the experimenter. When they were given a high
score they rated liking of the experimenter as higher (supports
operant conditioning). They also asked participants to rate how much
they liked a bystander. Liking of the bystander was also rated as
higher when they had been rated higher on the task (supports
classical conditioning). However, there are problems with this
being a laboratory study, for example, only liking was measured, not
how inclined participants were to form a relationship with the person.
Processes leading to just liking someone may be different to those
involved in choosing a mate.
This theory only explains the giving of rewards and
suggests that we are entirely selfish. However, it has
been found that we gain satisfaction from giving as
well as receiving. This has been especially found for
women, who have been found to be more focused on
rewarding than being rewarded in relationships. This
links into cultural differences: in many cultures,
relationships are formed for the good of the family or
group, rather than according to individual satisfaction.
This suggests that the theory does not hold across
gender or culture (IDA).
Social Exchange Theory can also be put in the
context of formation
The process of setting up the
cost:reward ratio is sampling (the
potential costs and rewards are
explored), bargaining (an acceptable
ratio is negotiated), commitment
(exchange of rewards and
acceptance of costs begins) and
institutionalisation (costs and
rewards become firmly entrenched
and there is more focus on the
relationship itself.
Maintenance of Romantic Relationships
Social Exchange Theory
This is an economic theory suggesting that relationships
are a series of exchanges of things that are rewarding and
costly, in the expectation of making a profit. If the
relationship is profitable then it will succeed.
The theory includes the concept of a comparison level. This is a
standard based on past experience and general expectations that a
relationship must exceed in order to be profitable. The comparison
level for alternatives is a related concept that suggests that when
people in a relationship are presented with another potential mate,
they weigh up the costs of ending their current relationship with the
rewards of being with the other person.
This theory can be applied to real
life situations, as it can explain
why women stay with an abusive
partner, as if investments in the
relationship are high, e.g. financial
security, children, and alternatives
are low, e.g. nowhere to live, then
the relationship might still be
considered profitable. This has
implications for intervention in
these relationships (IDA -
application to real life).
The theory is very clinical and suggests that people
are only motivated by the desire to make a profit,
however, this is not necessarily the case, especially
in different cultures where relationships are formed
for the good of the community, and thus making an
individual profit is not relevant (IDA - culture).
However, even in Western relationships it has been
found that security is more highly valued than
making a profit.
SET ignores many factors to do with relationship
maintenance. It cannot explain why some people
leave profitable relationships despite having no
alternative, and it does not detail how many
costs the comparison level can handle before the
relationship ceases to be profitable. It also
ignores the social aspects of relationships, for
example, how partners communicate and
interpret shared events. Not taking these factors
into account weakens the theory, as it makes it
an incomplete explanation.
Equity Theory
This is another economic theory, that suggests
that relationships are profitable when both
partners feel it is equitable, that is to say that
"benefits - costs" is equal for both partners.
People who give a lot in relationships and receive
little in return will perceive inequity and be
dissatisfied. For this reason, partners are both
motivated to reduce inequity and achieve fairness.
Equity does not necessarily mean equality. It is to do with
perceived fairness rather than equal contribution, eg. it
might be considered fair that the partner with the higher
salary pays for more things for both partners.
The theory is culturally biased, as it has
been found that equity does not have
the same importance in a relationship
everywhere as it does in America. For
example, in a study of European
students it was found that they
preferred equality in their relationships
to equity. Therefore the theory appears
to be ethnocentric.
An obvious prediction of the theory is that inequitable
relationships should lead to breakdown. However, in a
longitudanal study of 1500 couples into marital inequity,
it was found that marital inequity only correlated with
later marital breakdown when the woman felt
underbenefitted. The theory, however, suggests that
feeling overbenefitted should also lead to dissatisfaction,
and does not account for gender differences between
women and men (IDA - gender differences). Therefore it is
an incomplete explanation of relationship maintenance.
There is a competing proposal that while some relationships,
eg. business relationships are economic, romantic
relationships are communal, and involve a desire to meet the
needs of the partner and the belief that things will balance
out in the long term. The theory is deterministic to suggest
that people will only seek a profit in relationships, as humans
also have an altruistic side, and altruism is often seen as
attractive (IDA - determinism).
Breakdown of Romantic Relationships
Duck's Reasons for
Relationship Breakdown
Extramarital affairs can be seen as
being caused by a lack of skills and
stimulation. In one study, participants
were asked to think of reasons for
infidelity. Factors such as sexual
boredom were more often reported
by men, whereas women were more
likely to blame emotional reasons
such as lack of attention. Despite the
gender differences, these factors are
the type of thing that the theory
suggests would cause relationship
dissatisfaction. However, there are
methodological issues with this
research, as participants were only
asked to think of reasons, not give
reasons for their own infidelity. In the
case of actual infidelity, other factors
might be more important.
It has been found that when partners'
relationship skills have been enhanced,
relationships are of a better quality. Fifty
couples who received couples coping
enhancement training (CCET) were compared
to a control group who had not. They reported
much higher marital quality after the CCET.
This supports the model by suggesting that
lack of skills does lead to a lower relationship
quality, and suggests a practical application of
the theory to real life (IDA). However, the
couples receiving training were not on the
verge of relationship breakdown, so it cannot
be inferred from the study whether lack of
skills leads to relationship breakdown or just
a lower quality of relationship.
Lack of Skills (such as
interpersonal skills and
social skills), Lack of
Stimulation (such as
feeling the relationship is
going nowhere) and
maintenance difficulties
(such as living far apart).
Reasons for Relationship
Breakdown does not separate
male and female viewpoints.
Studies have found that women
are more likely to express
unhappiness or incompatibility
as reasons for breakdown,
whereas men are more likely to
give reasons such as sexual
withholding. The theory does
not account for gender
differences, thus this weakens
it (IDA).
Both these theories have
been criticised as being
culturally biased as these
modes of relationship
breakdown are
individualistic and may not
extrapolate across cultures.
Rollie and Duck's Model of
Relationship Breakdown
Breakdown: dissatisfaction with relationship.
Intrapsychic processes: ruminating on
dissatisfaction and justifying withdrawal.
Dyadic processes: discussion of discontent
with partner, uncertainty, anger, hostility.
Social processes: seeking third party support,
confirming the inevitability of breakdown.
Gravedressing processes: saving face,
preparing stories, separating lives, strategic
reinterpretation, justification. Resurrection
processes: establishing what has been learnt
and what to seek from future relationships.
This model offers
implications for intervening
in a relationship and ideally
saving it and improving it
instead. The model stresses
the importance of
communication and can help
to develop appropriate
interventions for each stage
(application to real life).
This is a socially sensitive
area of research, delving into
private matters. Participants
in experiments may
experience distress at being
asked to recall previous
breakdowns (IDA).
It has been found that people
who instigate relationship
breakdown experience fewer
negative effects than the person
who is being broken up with.
This is a criticism of the theory
as it suggests the same
processes apply to both parties
of the relationship.
Evolutionary Explanations
Parental Investment Theory
The premise of this theory is that males and
females do not invest equally in offspring, as a
female can only have a limited number of
offspring and have high childcare requirements,
whereas a male can have a virtually unlimited
number of children and has low childcare
requirements. This leads females to look for
quality rather than quantity, seeking a man with
resources to bring up the offspring, whereas men
look for quantity over quality as they have a large
capacity to reproduce and risk cuckoldry if they
invest in offspring.
This theory also suggests that men
are more upset due to sexual
jealousy, due to the risk of
cuckoldry, whereas women are more
upset due to emotional jealousy, due
to the risk that her mate will leave
her and she will have no resources to
bring up the offspring. Men are more
jealous if their rival is high in status,
and are thus more likely to express
jealousy by displaying resources.
Women are more jealous if their rival
is attractive, and thus display
jealousy by attempting to enhance
their physical attractiveness.
Studies into women's sexual behaviour
support PI theory and can also explain a
desire for casual sex in women. A woman
may marry a man with good resources, but
seek to provide their offspring with better
genes through extramarital affairs. It is
difficult to assess this accurately, but an
anonymous survey with over 2700
participants suggested that up to 14% of
the population are the products of
extramarital affairs. This supports the idea
that women seek men with good resources,
however also look for good quality genes.
However (IDA), extramarital affairs are a
sensitive subject and people may display
social desirability even in an anonymous
study, as often people do not even want to
admit something to themselves.
Studies showing males' reticent attitudes to parenting support PI
theory, as they suggest that a reluctance to settle down with
offspring is biologically shaped. Participants were exposed to
parenting scenarios and their ANS arousal was measured. Males
showed significantly increased heart rate and stress response when
exposed to scenarios highlighting the costs of parenting compared
to women. However, these results can be from a biological approach,
you could also interpret them from a psychosocial approach: men are
not biologically less prepared to raise children, just psychosocially
less prepared due to societal gender roles, and this is why costly
parenting acts as a stressor for them (IDA - approaches).
This theory is very determinist, suggesting
that men and women will always act in
certain ways (IDA). Humans have higher
order thinking skills and seek more out of a
relationship than just children. Furthermore,
the evolutionary fear of cuckoldry is no longer
relevant with modern-day paternity tests.
Furthermore, it is irrelevant to other aspects
of modern day life, such as homosexual
relationships. Therefore, the theory is not
generalisable in the modern day.
Sexual Selection
Intersexual selection: Preference of
one sex for members of the opposite
sex who possess certain attributes
reflecting health, fertility or resources.
Intrasexual selection: Members of
the same sex compete for access to
members of the opposite sex. The
victorious are able to reproduce
and pass on their genes.
Short-term mating preferences:
Men have a greater desire for casual
sex and seek sex earlier in a
relationship, as they wish to
impregnate as many women as
possible to pass on their genes.
Women, however, have no desire for
casual sex, as their prerogative is to
get pregnant by a man with enough
resources to look after the offspring.
Long-term mating preferences: Men
may eventually settle down and provide
resources for their offspring in order to
give them the best chance of survival.
Both partners will be choosy in the long
term: women want a man with good
resources and men want a fertile woman
they can impregnate many times.
Studies support the idea of the importance of fertility in women for men, as men seem to
find women more attractive when they are in their oestrus phase, for example, lap
dancers have been found to earn twice as much money when they are in their oestrus
phase (however, this is correlational and so causality cannot be assumed. It could be that
women feel more attractive and are thus more confident when they are in their oestrus
phase).
Evidence has been found to support the theory's predictions on short
term mating preferences. In one study, male and female students were
asked by an opposite sex researcher: "I find you very attractive. Would
you a) go on a date with me, b) come back to my apartment with me
and c) have sex with me?" Responses for women were a)50% b)6% and
c)0%, whereas responses for men were a)50% b) 69% anc c) 75%. This
suggests that men are more inclined to engage in casual sex than
women, as the theory suggests.
The theory is very deterministic, as it suggests that men and women will always behave in
certain ways. However, modern day humans have higher order thinking skills and seek more out
of a relationship than just sex and children. The theory also cannot explain women's desire for
casual sex, giving it an inherent gender bias, and does in no way explain homosexual
relationships, meaning it is not generalisable in the modern day (IDA).
Effects of Early Experiences
Childhood: Parent-Child Relationships
Romantic love in adulthood is related to childhood attachment, caregiving and
sexuality systems. Later relationships are likely to be continuations of early
attachments because the early attachment figure provides a model for future
relationships. Knowledge about caregiving is learned by modelling the behaviour of the
primary attachment figure. Views on sex are also learned from early attachments, for
example, avoidant attachments tend to lead to seeking sex without love later in life.
The psychodynamic approach suggests that how we adapt to
adult relationships depends on how well we dealt with the
Oedipus/Electra complex in childhood. If a boy does not
successfully resolve his Oedipus complex, he may look for a
nurturing, care-taking woman in the future.
There is research support for the idea that early attachment type affects later relationships. It has
been found that individuals with attachment disorders in childhood struggle to build trust and
intimacy in adult relationships. In another study, participants who were rated as being securely
attached as infants were found to have higher social competence aged 6-8, be closer to their friends
ages 16 and were more expressive and emotionally attached to their partner in early adulthood.
However, research is mixed, and correlations from 0.1-0.5 between early attachment type and later
adulthood relationships have been found, meaning results are unreliable.
The idea that having a certain attachment type as a
child dooms you to having a certain type of relationship
as an adult is very deterministic. Other experiences and
personality factors are likely to have an effect.
The psychodynamic approach is very androcentric
and also unempirical and unscientific (IDA)
Childhood: Peer Interactions
Children learn how to conduct future relationships from early friendships with other children.
Children have experiences they internalise, and these affect their beliefs and attitudes. It is
suggested that children's friendships are important training grounds for adult relationships.
Close friendships give children a sense of alliance, intimacy, trust and confidence.
Theorists have not considered gender differences found in childhood
friendships, for example, girls tend to have more intimate friendships
whereas boys' are more competitive (IDA - gender differences)
Adolescence
Adolescence marks critical development, as the adolescent's primary
support network becomes their friends rather than their family.
Adolescents compare their relationships with their friends to their
relationships with their parents, and realise that their parents no longer
meet their attachment needs, leading them to seek other relationships.
Romantic relationships in adolescence serve the goals of separating from
parents and the experience of a different type of intimacy.
A study on the effects of dating
behaviour in 15-17.5 year olds found
that low-moderate dating in
adolescence predicted higher quality
adult relationships, whereas high
dating frequency predicted lower
quality adult relationships. Other
research has found that romantic
relationships in early adolescence have
negative effects, such as lower
academic achievement, but this effect
is not found in later relationships.
These studies suggest suggest the
theory is simplistic.
Many of the studies of
adolescent relationships
have been done in a
single school or city,
usually in the US. This
creates issues with the
studies' external validity,
and makes them
ungeneralisable (IDA).
The suggestion that
separating from parents in
adolescence is a main goal
is simplistic. Research
suggests that future
relationships are healthiest
when accompanied by
continuing warm and close
relationships with parents.
Culture
AO1
Mobility and Choice: In Western culture, due to geographical and social mobility,
people interact with a lot of other people on a daily basis, meaning there is a large
pool of choice from which to select mates. Non-Western cultures have fewer large,
urban centres and less social and geographical mobility, leading to less mate choice.
Individual Choice vs Choice made for Group Benefit: Individualist cultures highlight the importance
of individual choice and mutual happiness. Collectivist cultures tend to focus on the group, leading
to the formation of relationships that benefit the group, such as arranged marriages.
The Value of Continuity: Non-Western cultures tend to regard things such as ancestry
and heritage as important and are suspicious of change. This leads to an expectation
of permanence in relationships. In Western cultures, change is usually viewed as
progress, and this leads to an acceptance of more temporary relationships.
The Social Norm of Reciprocity: Reciprocity in
individualist cultures is generally voluntary, whereas in
collectivist cultures is is more obligatory, and a failure to
reciprocate can have large consequences.
Explicit and Implicit Rules: Having rules in relationships has been
found to be important across cultures, even though the rules
themselves differ. Some rules are similar across culture, for example,
marriage, but some are different, for example, polygamy.
AO2
Non-voluntary relationships such as arranged marriages have low
divorce rates, and spouses often report that they have fallen in love
over time, suggesting that non-Western relationships can promote
high levels of happiness and commitment. However, other research
refutes this, for example, the declining popularity of arranged
marriages in non-Western cultures, that marriage satisfaction has
been found to be higher for people in non-arranged marriages, and
that freedom of mate choice promotes marital stability.
Evidence of romantic love has been found in 90% of non-Western
cultures. This is supported by evidence from fMRI scans as they
seem to show a functionally specialised system that lights up in
the brains of people in love (this is a good way to test it because it
is objective). This suggests that love is universal, and has evolved
to promote survival and reproduction in humans. This means that
relationships can be fairly compared across cultures, as the same
concept of love is present in all cultures.
Psychologists have traditionally ignored cultural
differences in relationships because of needing to use
experimental methods, using laboratory studies and living
in Western cultures. This means that the majority of
research into relationships does not take account of cultural
differences in relationships, meaning that our
understanding of the full effect of culture on relationships is
lacking, due to the ethnocentric approach to research (IDA).
There is support for the idea that increased
mobility increases choice and thus leads to less
permanent relationships. In Britain, divorce rates
multiplied by six between 1960 and 2000, in line
with urbanisation, suggesting that due to the
increased choice, relationships were becoming
more temporary. However, this study is
correlational, and there might be other factors that
contribute to the increased divorce rate, for
example, the declining power of the church and
turn away from religion
