Kelman Three types of conformity:
Compliance
Identification
Internalisation
Compliance - the shallowest level of conformity. The person changes how they act in public, but not their private beliefs. This is short term and usually the result of NSI
Identification - middle level of conformity. The person changes their public behaviour and private beliefs, but only while they are in the presence of the group. This is short term and usually the result of NSI
Internalisation - the deepest level of conformity. A person changes their public behaviour and private beliefs. This is long term and usually the result of ISI.
Normative social influence - conforming to be accepted and feel like that they belong to a group. The person conforms because it is socially rewarding or to avoid social rejection. It is more short term
Informative social influence - Conforming to behaviour of others when you believe they are likely to be correct.
