Social influence Flashcards
(151 cards)
define conformity
the tendency to change what we do, think or say in response to the influence of real or pressure from a majority group
what are the two explanations for conformity
-Normative social influence –> we agree with the opinion of the majority because we want to be accepted, gain social approval and be liked. This may lead to compliance
-Informational social influence –> 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 (may lead to internalisation)
what are the three types of conformity suggested by Klerman
Compliance –> When an individual changes their behaviour in response to an explicit or implicit request made by another person (the most shallow) - superficial as only change public beliefs
Internalisation –> When a person changes both their public behaviour and private beliefs (deepest level)
Identification –> When a person changes their public behaviour and private beliefs but only in the presence of the group they are identifying with
what was the aim of sherifs experiment
demonstrating that people conform to group norms when they are put in an ambigious situation
what was the method of sherifs experiment
Sherif used a lab experiment to study conformity. He used the autokinetic effect where a small spot of light was projected in a dark room that appears to be moving even though it is still. Participants were falsely told the experimenter would move the light. There were 3 phases. In the first phase participants were by themself and estimates were varied widely. In the second phase participants were in a group where estimates tended to converge and be more alike. In the final phase participants were alone but their estimate was similar to their previous group estimate.
Conclusion of sherif’s experiment
When in an ambiguous situation a person is more likely to turn to others for guidance as they want to do the right thing.
define majority influence
refers to the process by which the majority alters the attitudes and behaviour of the minority. This may be due to normative social influence but can also be due to informational social influence, where the minority yields to group pressure because they perceive the majority as having more knowledge or information
Aim of Asch’s line study (1951)
investigate conformity and majority influence
what was the procedure of Asch’s line study
- Participants and confederates were presented with 4 lines; 3 comparison lines and 1 standard line
- They asked to state which of three lines was the same length as a stimulus line
- The real participant always answered last or second to last
- Confederates would give the same incorrect answer for 12 out of 18 trials
- Asch observed how often the participant would give the same incorrect answer as the confederates versus the correct answer
Findings of Asch’s line study
36.8% conformed
25% never conformed
75% conformed at least once In a control trial,
only 1% of responses given by participants were incorrect (which eliminates eyesight/perception as an extraneous variable, thus increasing the validity of the conclusions drawn)
what are the variables affecting conformity
group size
unanimity of conformity
difficulty of task
how does group size affect conformity
An individual is more likely to conform in a larger group. There was low conformity with group size of confederates were less than 3 - any more than 3 and the conformity rose by 30%. A person is more likely to conform if all members of the group are in agreement and give the same answer, because it will increase their confidence in correctness of the group, and decrease their confidence in their own answer. Conformity does not seem to increase in groups larger than four so this is considered the optimal group size. This shows that the majority must be at least 3 to exert an influence, but an overwhelming majority is not needed in all instances to bring about conformity
how does unanimity of majority affect conformity
An individual is more likely to conform when the group is unanimous i.e. all give the same answer, as opposed to them all giving different answer. When joined by another participant or disaffected confederate who gave the correct answer, conformity fell from 32% to 5.5%. If different answers are given, it falls from 32% to 9%. . The more unanimous the group is, the more confidence the participant will have that they are all correct, and therefore the participant’s answer is more likely to be incorrect. Unanimity is vital in establishing a consistent majority view, which is particularly important by providing normative social influence.
how does difficulty of task affect conformity
An individual is more likely to conform when the task is difficult. For example, Asch altered the (comparison) lines (e.g. A, B, C) making them more similar in length. Since it was harder to judge the correct answer conformity increased. When the task is difficult, we are more uncertain of our answer so we look to others for confirmation. The more difficult the task the greater the conformity. This suggests that informational social influence is a major mechanism for conformity when the situation is ambiguous and the individual does not have enough of their own knowledge or information to make an informed decision independently, and so has to look towards others.
conclusion of Asch’s line experiment
In a group situation there is a tendency to conform to the judgements of others, even when these judgements are quite clearly incorrect. However, there are considerable individual differences in whether people or not conform.
Strength’s of Asch’s line experiment
-High internal validity - There was strict control over extraneous variables, such as timing of assessment and the type of task used. The participants did the experiment before without confederates to see if they actually knew the correct answer, thus removing the confounding variable of a lack of knowledge. This suggests that valid and reliable ‘cause and effect’ relationships can be established, as well as valid conclusions. Lab experiment
- Extraneous and confounding variables are strictly controlled, meaning that replication of the experiment is easy. Successful replication increases the reliability of the findings because it reduces the likelihood that the observed findings were a ‘one-off’
weaknesses of Asch’s line experiment
-Lacks ecological validity - it was based on peoples’ perception of lines and so the findings cannot be generalised to real life as it does not reflect the complexity of real life conformity i.e. where there are many other confounding variables and majorities exert influence irrespective of being a large group.
limited application of findings = Neto (1995) = women might be more conformist as they might be more concerned about social relationships than men
-Lacks population validity due to sampling issues - For example, the participants were only American male undergraduates, and so the study was subject to gender bias, where it is assumed that findings from male participants can be generalised to females (i.e. beta bias).
-Ethical issues: - there was deception as participants were tricked into thinking the study was about perception rather than compliance so they could not give informed consent. - There could have been psychological harm as the participants could have been embarrassed after realising the true aims of the study. - Such issues simply mean that a cost-benefit analysis is required to evaluate whether the ethical costs are smaller than the benefits of increased knowledge of the field. They do not affect the validity or reliability of findings.
conducted in individualistic not collectivistic cultures
-Lacked temporal validity - The social context of the 1950s may have affected results. For example, Perrin and Spencer criticised the study by stating that the period that the experiment was conducted in influenced the results because it was an anti-Communist period in America when people were more scared to be different i.e. McCarthyism. Thus, the study can be said to lack temporal validity because the findings cannot be generalised across all time periods.
what type of conformity goes with which explanation
internalisation –> informational social influence
compliance –> normative social influence
What are the difficulties in distinguishing between NSI and ISI
The original two process theory stated that people either conform due to ISI or NSI. For example Asch’s non conforming confederate condition conformity levels reduced. This may have been due to NSI in having social support from someone else of reduced ISI due to another source of information. This shows that it is not always possible to be sure which is the influencing factor. This therefore reduces the validity of the theory
Support for normative social influence
Asch’s line study
-Unanimity in a group increases conformity
Support for informational social influence
Asch’s made comparison lines more similar so task was more difficult. Participants conformed as they wanted to be correct.
Jenness jelly bean experiment
what was Jeness’ experiment (1932)
Aim: investigate how humans conform based on the behaviour of others surrounding them
Procedure: gathered 101 psychology students who had to estimate how many beans were in a jar. Then they were split into groups to communicate guesses. They then had to estimate again.
Results: Males changed answer by 256 beans and females by 382 beans
Conclusion: Demonstrates informational social influence especially in an ambiguous situation
what are the strengths and limitations of Jeness’s experiment
Strengths –> ethical study (no psychological harm etc)
-ambigious question
Limitations –> Experiment had no controls so extraneous variables were not accounted for
—> ambigious so does not inform us about conformity in non-ambigious situations
–> included both normative and informational social influence
