We could conclude the reason of conformity into two categories:

* To?gain?information?from?others?for?proper?behavior;

* To?avoid?punishment?or?to?gain?a?reward.

Conformity?resulting?from?the?observation?of?others?for?the?purpose?of?gaining?information?about?proper behavior?tends?to?be?more?powerful?than?that?in?the?interest?of?being?accepted?or?of?avoiding?punishment.

Compliance,?Identification?and?Internalization

Compliance:best?describes?the?behavior?of?a?person?who?is?motivated?by?a?desire?to?gain?reward?or?avoid?punishment.?Typically,?the?person's?behavior?is?only?as?long-lived?as?the?promise?of rewards or the threat of punishment.

Identification:is?a?response?to?social?influence?brought?about?by?an?individual's?desire?to?be?like?the influencer.In?identification,?we?behave?because?it?puts?us?in?a satisfying?relationship?to?influencer.

It?is?called?a?"good-old-Uncle-Charlie?phenomenon".

Internalization:the?internalization?of?a?value?or?belief?is?the?most?permanent,??most?deeply?rooted?response?to?social?influence.?The?motivation?to?internalize?a?particular?belief?is?the?desire?to?be?right.

Differences

1. Compliance is the least enduring, and has the least effect on individuals. People comply merely to gain reward or to avoid punishment, and it can hardly continue when the rewards or punishments disappeared.

2. Identification?doesn't?need?continuous?rewards?or?punishments.?It?works?even?when?the?person?with whom we?identify?is?not?present.?All?that?it?needed?is?our?desire?to?be?like?the?person.?But?when?a?more admirable?person/group appears,?a?more?important?identification?may?supersede?a?previous?one.

3. Internalization?is?the?most?permanent?response?to?social?influence?precisely because?our motivation to be right.?It?is?a?powerful?and?self-sustaining?force that?it?does?not?depend?on continuous rewards or punishments, or?our?continued?esteem?for?some?person?or?group.

Any?specific?action?may?be?due?to?either?compliance,?identification,?or?internalization.
