Social influence Flashcards
What is social influence?
- Attitudes/behaviours influenced by real/implied presence of others
- Change of attitudes/beliefs/opinions/values and behaviour
What are 7 key functions of social norms?
- reduce uncertainty about how to behave
- coordinate individual behaviour
- help with distribution of outcomes
- potentially dynamic
- evaluative - violating norms leads to negative responses
- descriptive and injunctive
- communicated implicitly, explicitly and through inference
What did Sherif (1936) study relating to socially facilitated influence?
Autokinetic effect:
- optical illusion
- pitch black room -> point of light 5m away
- light point appears to move
- 1/2 took part individually then came together in groups, other half took part as groups then individually and asked to give an oral estimate of how much they thought the light had moved
- The subjects conformed to group norms, often without even realizing it. Group norms were established by finding an intermediate position, with the extreme positions moving toward the middle.
What are 3 types of social influence?
- compliance
- conformity
- obedience
What is compliance?
- public change in behaviour
- no private change in attitudes
- research has focussed on factors affecting compliance
What is the foot-in-the-door compliance technique?
Small request -> big request
What did Freedman and Fraser (1966) research relating to foot-in-the-door?
- Can our researchers come to your home to do a 2 hour survey of household product use? - just over 20% compliance
- When same question asked after ppts had agreed to take part in a short telephone survey, just over 50% complied
Why does foot-in-the-door work as a compliance technique?
We infer what we are from what we do: if we are helpful on first occasion, we must be a helpful person, and so we should be helpful on second occasion
What is the door-in-the-face compliance technique?
Big request first -> unlikely to be successful
Followed with more reasonable request -> greater likelihood of compliance than if 2nd request was presented in isolation
What did Cialdini et al. (1975) study in relation to the door-in-the-face compliance technique?
‘will you volunteer at a young offenders’ institute for 2hrs p/w for the next 2yrs?’ -> minimal compliance
‘will you take these young offenders to the zoo?’
- after 1st request, 50% compliance
- without 1st request, 17% compliance
2nd request perceived as a concession on the part of the requester
What is conformity?
- influence in groups
- more indirect form of influence
- behaviour guided by group norms
- affects attitudes as well as behaviour
- informational vs normative influence
What is normative influence? (conformity)
Desire to be liked
What is informational influence? (conformity)
Desire to be right - in Sherif’s autokinesis study, people might assume that other group members have a more accurate judgement than they do
What problem did Asch (1952) address with Sherif’s (1936) study?
No clear right answer
- people might conform to group norms in ambiguous situations but what about when there is an obvious and objective criteria on which to base one’s judgement?
Solution: Line-length judgement experiment
What was Asch’s 1952 line experiment?
Which of the lines is the same length as the target line?
- ppts in group of 7-9 (rest were confederates who had been instructed to give wrong answer)
- 50% of ppts conformed to majority and gave wrong answer in at least 1 trial
- without group (control) less than 1% gave wrong answer.
Reasons for conformity:
- confusion
- group pressure
- fear of disapproval
- feelings of anxiety/loneliness
- group may have been right
- didn’t want to stand out
Most common response over all trials was resistance
Who studied minority influence?
Moscovici (1976)
What is minority influence?
Minorities require consistency to overcome majority rejection
- when minorities are persistent, they can succeed at influencing majority
What did Moscovici et al. (1969) study in relation to minority influence?
6 ppts presented with a series of slides unambiguously blue and differed only in light intensity - had to say colour of slide
- in one condition, 2 confederates answered green on every trial
- incorrect guesses rose from 0.25% to 8.42%
What is conversion theory (Moscovici, 1980)?
Group discussion -> minority influence -> validation -> conversion (indirect, delayed, durable)
Group discussion -> majority influence -> comparison -> compliance (direct, immediate, temporary)
How does Nemeth (1974) show that consistency and confidence aid minority influence?
Personal injury claim given to 5 subjects (1 confederate)
Before discussion - compensation of $12000 to $20000 deemed fair
Discussion - 40 mins to discuss the case
Conditions:
- chosen
- chosen head
- chosen side
- assigned
During discussion - confederate consistently presents 6 arguments for compensation of only $3000
Findings: only when confederate chose the head seat were they influential
