In making wedding preparations, jamarcus conforms to the expectations of his future bride's family in order to win their favor. his behavior illustrates the importance of social influence.

The correct answer is Normative Social Influence.

It may be defined as influence resulting from a person's desire to gain approval or avoid disapproval. The normative social influence involves conforming in order to be accepted or liked by a group, not necessarily because one actually believes the things one is doing or saying. This tendency is due to the fact that one of core instincts is to long to be in a social group of some sort. This comes into play because when a bunch of people get together and want to stay together there needs to be some degree of agreement as far as rules, morals, and behaviors because otherwise there would be issues among the members.
