social influence Flashcards
social psychology
looks at how people interact and influence each other
social influence
when the behaviour of others causes a person to change their behaviour
conformity
when the behaviour of an individual or a small group is influenced by a larger group
study for conformity
Asch’s line study
Procedure: 123 US male undergraduate students participated in a study where they judged line lengths by saying out loud which comparison line matched the standard line. They were in groups of eight, however each group had one REAL participant - the rest were confederates. In 12 out of the 18 trials, confederates gave an incorrect answer.
Findings: participants conformed to the majority 37% of the time and 75% at least once. In control trials, participants gave the wrong answer 1%
Conclusion: study showed normative conformity as majority of the participants conformed to the rest of the group
variables affecting conformity: group size
having a bigger group means that you are more likely to conform compared to having a smaller group.
- Asch (1956) conducted his experiment again with fewer confederates, and found conformity decreased to 14% with two confederates, and 32% with 3
variables affecting conformity: unanimity of the group
Asch wondered whether the presence of non-conforming person would affect the participants conformity - he introduced a confederate who said the same answer as the participant
- conformity decreased from 37% to 5.5%
variables affecting conformity: task difficulty
Asch made the task more difficult by making the lines more similar.
- This increased conformity rates due to the uncertainty of the real participants
evaluation of Asch’s study
✔️lab experiment (control over EV) ✔️standardised procedures ❌low ecological validity ❌artificial tasks (not applicable to real life) ❌ethical issues (deception & protection)
internalisation
- person conforms publicly & privately because they have internalised and accepted the views of the group
- deepest form of conformity
identification
- person conforms publicly as well as privately, but the change of belief is often temporary
compliance
- person conforms publicly but NOT privately, and therefore continues to privately disagree
- shallowest form of conformity
conformity explanation: informational social influence
- when you agree with a group because you are unsure of a situation & we believe others have the right information
research to support informational social influence
- participants saw a video of what they thought were other people reacting to the candidates speeches
- this produced a large shift in participants views on each candidate due to the participants thinking the reactions they watched were correct
conformity explanations normative social influence
- when you agree with a group due to a need for social approval & a desire to avoid social rejection
research to support normative social influence
- hotel guests were exposed to the normative message “75% of guests reused their towels each day rather than requiring a fresh one”, and their own towel usage then decreased by 25%
- this shows people will change their behaviour to fit in with the majority
evaluation of explanations of conformity
✔️evidence to support (after Asch’s study, some participants that conformed said they did because they were afraid of disapproval)
❌nafiliators (people who are greatly concerned with being liked by others)
social roles
the ‘parts’ people play as members of social groups
- our role is often accompanied with expectations
study for conforming to social roles
Zimbardo’s Stanford Prison Experiment
Procedure: 21 male college students randomly assigned into two groups - prisoner or guard. When the prisoners were arrived at the prison they were stripped off all identity
Findings: both guards and prisoners easily conformed to their roles, but the guards conformed quicker. Within hours of the study beginning, guards harassed prisoners and behaved in a sadistic manner. The prisoners started taking prison rules very seriously, and some began siding with the guards. Some prisoners even began to leave the study early
Conclusion: people will conform to the social roles they are expected to play
evaluation of Zimbardo’s study
✔️realistic ✔️ethics (withdrawal & debriefing) ❌ethical issues (deception, protection) ❌lab ❌sample bias (androcentric, western culture, small sample size)
obedience
a form of social influence concerned with direct order
- a figure of authority gives orders, and has the right to punish if these orders aren’t followed
study for obedience
Milgram
Procedure: 40 males aged between 20 and 50years took part in Milgram’s shock experiment. They were introduced to Mr Wallace, an actor, and were assigned the role of teacher or learner (it was rigged so the participant was always the teacher). The learner was strapped to a chair and the participant began asking questions - if the learner got one wrong they would be shocked, and the voltage kept increasing.
Findings: all participants gave Mr Wallace at least 300 volts, but 65% gave the maximum of 450 volts. Throughout the study many participants showed signs of nervousness, as they sweat, trembled, stuttered and dug fingernails into their flesh.
Conclusion: participants were distressed by the task as they believed they had killed Mr Wallace, and when interviewed they said they felt as if they had to continue the study due to the experimenters orders
evaluation of Milgram’s study
✔️laboratory experiment (control over EV)
✔️ethics (debriefed)
❌ethical issues (deception, protection, withdrawal)
❌sample bias (androcentric, small sample size)
situational variables
features of the environment which may influence a person’s behaviour (proximity, location, uniform)
situational variable: proximity
refers to how close someone is to you
- the closeness of the authority figure to you and whether this will influence your obedience
⚫️teacher + learner in same room = decrease from 65% to 45%
⚫️teachers involvement = decrease to 30%
⚫️experimenter left the room and called the teacher = decrease to 20.5%
situational variable: location
Milgram’s original study conducted in Yale, one of the most prestigious universities in America (gave the study legitimacy and authority)
situational variable: uniform
uniforms encourage obedience as they are recognised as a symbol of authority
- obedience decreased to 20% when the experimenter wore everyday clothes instead of a lab coat
