I'm not back to school yet I'm afraid, but am confident I will be in time for our lesson on Thursday. We will then review the Evolutionary approach's explanations for human reproductive behaviour, and will look at theories of the formation and maintenance of relationships (the first section in your textbook).
Read this, and make notes on the Filter Model, and Reward/Need Theory of relationship formation.
Reward/need is basically the behavioural approach applied to relationships - a relationship forms if the needs of both parties are met, and they are rewarded for spending time together, with primary reinforcers (hopefully just food on the first date) and secondary reinforcers (laughing at each other's jokes, compliments on hair etc). This idea is developed into a theory of the maintenance of relationships (having got together, will the couple stay together?), called Social Exchange Theory. This basic idea (that costs as well as rewards need to be taken into account) is adopted by other so-called 'economic' theories. Read about these and make brief notes on the following:
Social Exchange Theory
Interdependence Theory
Investment Model
Equity Theory
