outcomes received in a relationship could define a person's attractions to relationships. Homans Homans based his theory on concepts of equilibration, expectancy and distributive justice in dyadic exchange. With this, he tries to explain the social interaction in small groups and the rewards received proportional to their costs and investments. Homans summarizes the system in three propositions: success, stimulus, and deprivation–satiation proposition, described below. Success proposition: When one finds they are rewarded for their actions, they tend to repeat the action. Stimulus proposition: The more often a particular stimulus has resulted in a reward in the past, the more likely it is that a person will respond to it. Deprivation–satiation proposition: The more often in the recent past a person has received a particular reward, the less valuable any further unit of that reward becomes. Blau Blau's theory is very similar to Homans’. However, he uses more economics terms and it is based principally on emergent social structure in social exchange patterns in small groups. His theory analyzes the development of exchange theory in economics without emphasizing on the psychological assumptions. He contributed to the idea of distinguishing between social and economic exchanges and exchange and power. The goal of his theory was to identify complex and simple processes without ignoring emergent properties. Blau's utilitarian focus encouraged the theorist to look forward, as in what they anticipated the reward would be in regards to their next social interaction. Blau felt that if individuals focused too much on the psychological concepts within the theory, they would refrain from learning the developing aspects of social exchange. Blau emphasized technical economic analysis whereas Homans concentrated more on the psychology of instrumental behavior. Emerson Emerson was inspired by Homans and Blau's ideas. He focused on the interaction and relationship between individuals and parties. His view of social exchange theory emphasizes the resource availability, power, and dependence as primary dynamics. He thought that relations were organized in different manners, and they could differ depending on the type and amount of the resources exchanged. He poses the idea that power and dependence are the main aspects that define a relationship. According to Emerson, Exchange is not a theory, but a framework from which other theories can converge and be compared to structural functionalism. Emerson's perspective was similar to Blau's since they both focused on the relationship power had with the exchange process. Emerson says that social
