When a person changes their attitudes or behaviour due to implied pressure from another group or individual. Conformity usually occurs amongst people with equal status. There are 3 types: Compliance, internalisation, identification.
Compliance
When a person shows a short-term change in their public behaviour, but their private attitudes remain the same. It occurs easily to temporarily fit in or avoid conflict with the majority group. It lasts whilst the person is in the presence of the majority group.
Identification
When a person shows a lasting change in their public and private attitudes or behaviour in order to show groupmembership. It occurs moderately easily to show a sense of belonging to the majority group. It lasts whilst the person 'identifies' with a particular group.
Internalisation
When a person shows a permanent change in their public and private attitudes or behaviour because they agree with the majority group. It does not occur easily because it involves meaningfulpersonalchange. It lasts indefinitely because the person actually agrees with the majority group.
