Normative social influence is when someone changes their behaviour to meet expectations. These can be their own expectations for themselves or the expectations others have for them. The influence will be bigger between people in a group than between two people, for example. Furthermore, the normative influence is smaller when someone feels that there is no need for them to conform. Additionally, not conforming to these expectations can make someone feel scared or guilty. For example, a small child might laugh with their family even if they cannot understand the joke yet.
