Theory 1: Reinforcement affect Model (BYRNE and CLORE, 1970)
We enter into a relationship because the individual concerned creates positive feelings in us, which makes them more attractive to us.
A02: Limitations
Explores only one factor that may affect liking
Probably only relevant to certain kinds of relationships
Does not account for gender and cultural differences
A01 -
Operant conditioning - We like some individuals because they provide us with direct reinforcement (i.e. they make us feel good.
A02: This is supported by... GRIFFIT and GUAY (1969) who found that participants rated an experimenter more highly if he or she had given them a positive evaluation.

Classical Conditioning - we like some individuals because they are associated with pleasant events.
A02: This is supported by... GRIFFIT and GUAY (1969) who found that onlookers were also rated more highly when the experimenter had rated participants positively.

Affect - these feelings lead to either a postive (if they make us feel happy) or negative (if they make us feel unhappy) evaluation of the individual concerned.
A02: This supported by... CUNNINGHAm (1988), who found that men who watched a happy movie later interacted more positively with a female and disclosed more to her.
(Operant + Classical Conditioning - Affect)
Commentary on learning theory:
Learning theory, which underlies this approach, is supported by well-controlled experimental research.

Theory 2: Social exchange theory (THIBAULT and KELLEY, 1959)
The formation of relationships is a two-way process, involving an interaction between two partners, each with their own needs and expectations.
A02: Strengths
This theory is relevant to many different kinds of relationships
It can explain individual differences between and within individuals
A01 - Stages in the development of a relationship
4 of 7
THIBAULT and KELLEY (1959) believed that there were four stages in the development of a relationship
Sampling - consider potential benefits and costs of a new relationship and compare it other relationships available at the time.
Bargaining - as the relationship develops, partners give and recieve rewards; this tests whether a deeper relationship is worthwhile.
Commitment - predictability increases; each partner knows how to elicit rewards from the other, and costs are lowered.
Institutionalisation - norms are developed within the relationship; establishing the patterms of rewards and costs for each partner.

A02: Limitations of four stages:
The theory ignores the social aspects of relationship
If focuses only on the selfish nature of relationships
It ignores 'fairness of exchange' rather than simply seeking a profit
A01 - Profit and Loss - In any relationship, individuals try to maximise their rewards (profit) and minimise their costs (loss).
A01 - Comparison Level (CL) -A produce of our experiences in other relationships together with what we might expect from this one. Relationships that exceed our CL are judged worthwhile.

A02:
This is supported by... RUSBULY and MARTZ (1995) who used this theory to explain why some women stay in abusive relationships.
However... ARONSON and LINDER (1965) found that increases in reward, rather than constant reward are crucial.
This is supported by SIMPSON et al. (1990) who found participants who were involved in a relationship gave lower attractiveness ratings to possible opposite sex alternatives (persumably to protect their own relationships).
