How groups influence behaviour

How Groups Influence Behaviour


We learn what is expected of each role

Social groups pressure us to conform


Behaviour expectations or guidelines

a) mores – highly regarded moral views on behaviour, almost never broken

b) folkways – everyday habits or traditional practices concerning things such as manners or personal appearance

Chapter 8 groups and group behaviour

  • Sanctions – formal or informal penalty or reward given to ensure conformity

    informal - Eg. A smile or a frown

    formal – public rewards or punishments Eg. A suspension or a scholarship

How does a group influence one to conform

How Does A Group Influence One to Conform?

Psychological Perspective

Four factors that determine whether or not a person will conform to a group

1.Group attractiveness – the more attractive the group is to its members (how much they like, admire or want to be a part of the group), the more likely the are to conform

2.Group unanimity – when a group is in seemingly total agreement, there is great pressure to conform

Chapter 8 groups and group behaviour

3.Public vs. private response – when a person has to give their opinion in front of the group they are more likely to conform their opinion to match the groups’

4.Nature of the task – tasks or questions that are vague or have no clear answer are easier to have people conform to. When they are clearer, factual or on a topic you feel competent about you are less likely to conform

Asch's Conformity Experiment

Chapter 8 groups and group behaviour

Groupthink – when group members have such a strong desire to reach a consensus they don’t examine all of the options or consequences

  • Too little time evaluating alternatives

  • Important information is dismissed

  • There is the illusion of total agreement; people think they are the only ones who disagree and so say nothing

    Example of Group Think

    Candid Camera

    Dangerous Group Think

Why do people obey figures of authority

Why Do People Obey Figures of Authority?

  • An authority figure can use rewards or punishment to induce people to conform (or people think they will be rewarded or punished)

  • We know (or think we know) that conformity in necessary to provide order and security

  • People conform when they can (or think they can) shift responsibility for their actions to someone else.
