Group Polarisation
Group polarisation is the strengthening of attitudes in individuals when they are in groups of people who hold similar attitudes
Has an implication for government, religion, commerce and the justice system
Myers and Bishop (1970)
When students who were low in racial prejudice talked about racial issues, their attitudes became even more accepting. When highly prejudiced students talked about racial issues, they became even more prejudiced
Main and Walker (1973)
Analysed the decisions of Federal District Court Judges sitting either alone or in groups of three to see if group discussions were a factor. In the 1500 cases where judges sat alone they took an extreme course of action only 30% of the time. however, when sitting in a group of three this figure rose to 65%. Trained professional decision makers are subject to the forces of group polarisation
3 Main theories as to why group polarisation occurs
there are 3 main theories as to why it occurs
1. Persuasion --> people change their mind as a result of the rational arguments presented by others 2. Comparison --> people change their minds to fit in with their view of the sort of decisions their group should make 3. Differentiation --> people change their minds to fit in with their view of the sort of decisions their group should make
McCauley (2002)
Stated that terrorist mentality does not come out of thin air; rather it arises when people with a shaved grievance get together and talk in a group in which there are no moderating influences
Social Facilitation
Improved performance due to the presence of others
Social Inhibition

Latane and Darley’s Five Stage Decision Model (1970)
Formulated a 5 stage model to explain why bystanders at emergencies sometimes do and don’t offer help
STAGE 1 - Notice the situation
STAGE 2 - Interpret it as an emergency (looking at the behaviour of others)
STAGE 3 - Accept from personal responsibility to intervene
STAGE 4 - Consider what is the best form of intervention
STAGE 5 - Decide how to implement the intervention. Related to many variables and characteristics
Darley and Bateson (1973)
Students at a theological college on their way to present a sermon on helping passed a man slumped and groaning in a doorway.
10% of students that thought they were late helped.
63% who thought they were early helped.
Some didn’t notice the victim
Clark and Word (1972)
Asked participants to fill in a questionnaire either individually or in groups. In either condition, if a man walked through the room carrying a ladder and then screamed ‘oh my back’, all participants helped, compared to 30% when they heard just a crash
Cramer et al (1988)
Found that by standers trained in first aid are more likely to help
Conformity
Conformity is the tendency to adjust one’s thoughts, feelings and behaviour in ways that are in agreement with those of a particular individuals or groups, with accepted standards about how a person should behave in certain situations (social norm)
Asch’s Line Experiment
