Deutsch and Gerard (1955) developed a two-process theory, arguing that there are two main reasons people conform
They are based on two central human needs:
The need to be right (ISI)
The need to be liked (NSI)
Informational social influence - An explanation of conformity that says we agree with the opinion of the majority because we believe it is correct
We accept it because we want to be correct as well - this may lead to internalisation
Informational social influence: EXAMPLE
You may not know the answer to a question in class
But if most of your class gives one answer, you accept it because you feel they are likely to be right
We follow the behaviour of the group (the majority) because we want to be right
Informational social influence is a cognitive process because it is to do with what you think
It leads to a permanent change in opinion/behaviour (internalisation)
Informational social influence: WHEN
In situations that are new to a person (so you don't know what is right)
Where there is some ambiguity (so isn't clear what is right)
Crisis situations where decisions have to be made quickly and we assume the group is more likely to be right
Normative social influence - An explanation of conformity that says we agree with the opinion of the majority because we want to gain social approval and be liked
This may lead to compliance
Normative social influence:
Is about norms, ie what is 'normal' or typical behaviour for a social group
Norms regulate the behaviour of groups and individuals so it is not surprising that we pay attention to them
People do not like to appear foolish and prefer to gain social approval rather than be rejected
Normative social influence is an emotional rather than cognitive process
It leads to a temporary change in opinions/behaviour (compliance)
Normative social influence: WHEN
In situations with strangers where you may feel concerned about rejection
With people you know because we are most concerned about the social approval of our friends
In stressful situations where people have a greater need for social support
