2Overview
- Looking at a series of experiments that studied
the effects of social influence on both
individuals and small groups - processes of social influence
- Majority influence (conformity compliance)
- Minority influence (innovation)
3Objectives
- By the end of this lecture, you should be able
to - Define what is meant by the 'fundamental
attribution error' - Describe the two major mechanisms through which
groups influence their members - Discuss why conformity is thought to result from
exposure to a majority influence - Discuss the characteristics a minority should
have in order to exert influence over a majority - Report criticisms of the dual-process model and
alternative explanations of minority influence
4Social influence
- What is meant by social influence?
- the extent to which an individuals opinions,
attitudes and judgments are influenced by being
exposed to the views of others -
(Van Avermaet, 2001)
5Fundamental attributional error
- The attribution error refers to the effect of the
situation over above the effect of personality - Situational factors generally ignored
- Termed the fundamental attributional error
6Norm formation
- The development of group norms SHERIF (1936)
- Experimental paradigm based on perception of
motion - autokinetic effect paradigm
- A stationary but flickering single light in dark
room - optical illusion appears to move but doesnt
actually move
7Sherifs experimental design
- Private viewing task
- Private estimate of distance light moved over 100
trials (written down)- - Ss formed personal consensus
- Group viewing task
- Public judgement (state out loud how far moved)
Ss formed a group consensus - This effect influenced Ss later judgement when
subsequently asked to perform task again on their
own
8Why people conform
- Major mechanisms of how groups influence their
members - Informational influence
- Value of others opinions
- Generally useful source of information
- Adaptive advantage
- Normative influence
- Need to be accepted by others
- Need to be approved of by others
- Fear of being disliked
9Social influence (1950s) The Asch Conformity
Experiments
- Ss shown a standard line
- This was then to be compared against 3 other
lines which varied in length from the standard
line by between ¼ and 13/4 - A
- B
- C
10The Asch Conformity Experiments
- Ss sits in groups varying from 7 9 people
- All asked to state which line is same as standard
line - Only 1 subject (rest are confederates)
- Each confederate makes false judgment in turn
(out loud) - Ss goes last in making judgment
- Control group (no confederates)
- Ss judgments made in private
11Asch conformity experimentRESULTS
- Experimental group
- Many Ss conformed to confederates false judgments
on majority of trials - Most caved in on a few trials
- Control group
- errors only about 2
12Changes in size of stimuli/group
- Asch increased the disparity in line length
- Larger disparities
- 28 of experimental Ss still made errors
- Only 2 in control
- Asch decreased size of majority group
- 1 confederate to 1 Ss
- Abolished the group effect
- Even though confederate still went first.
13Increased sized of minority
- Introduced a partner
- 1 confederate (immed.) prior to Ss gave correct
response - Reduced majority effect to 13 of estimates
- Wrong minority of 1 (reverse of original
experiment) - I confederate gives wrong answer first but rest
of group were Ss - No majority effect
14Variations of stimulusCRUTCHFIELD (1955)
- Studies of attitude
- Free speech being a privilege rather than a
right, it is proper for a society to suspend free
speech when it feels threatened - 19 agreed with statement in private
- 58 agreed under pressure of group influence
15Variations of stimulus CRUTCHFIELD (1955)
- Statement presented to Army leaders
- I doubt whether I would make a good leader
- None agreed with statement in private
- 37 agreed under group pressure
- BUT
- When Ss were presented with judgements again in
private most reverted to their pre-group answers - No permanent attitude change as result of
experiment - So, more an effect of compliance than conformity
16Critique of Asch experiments PERRIN SPENCER
(1980)
- Generalisability of Aschs experiments?
- Failure to replicate line experiments with
British engineering, maths and chemistry students
(6 confederates, 1 Ss) - Only 1 out of 396 trials did a Ss join the
erroneous majority. - Stresses cultural rather than personality factors
in explaining conformity
17Difference between Asch Sherif studies
- Sherif (moving light)
- Subject didnt know wasnt correct answer
- Reasonable to consider others views
- Participants later adopted social norms
- Conformity leads to internalization
- Asch (parallel lines)
- Participants knew there was a correct answer
- Conformity does not lead to internalization
- Suggests important differences between compliance
and conformity
18Minority influence
- Minority influence exemplified in TV play film
Twelve Angry Men - 12 jurors have to decide over the guilt or
innocence of a young man charged with the murder
of his father. - At outset of the play a single juror in the
murder trial favours acquittal, other 11 jurors
favour conviction - By end of play unanimously not guilty
- The minority (of 1) has influenced a majority jury
19Minority influence and social change
- Most instances of minority influence or
innovation cannot be accounted for by the same
mechanisms that explain majority influence
(Moscovici, 1976) - Minorities are few in number
- No normative control over the majority
- More likely to be ridiculed by the majority than
taken seriously - Perceived as weirdos.
- Seem to have access to the same informational and
normative means of control either explicitly or
implicitly as a majority
20How do minorities influence others?
- Minorities influence others through their own
behavioural style - Make their proposition clear at the outset
- Stick to their original proposition
- Withstand the majority influence
21Behavioural Style
- Key factor in minority influence is consistency
of behavioural style - Consistent
- Across time situation (diachronic consistency)
- Across individuals (synchronic consistency)
- Strength of conviction
22Assumptions of of minority influence
- Minority can create conflict
- Creates doubt and uncertainty
- Solution cognitive change
- Minority can exploit majoritys dislike of
conflict - Influence is reciprocal
- Every group member both influences and is
influenced, irrespective of status
23Genetic model of social influence (Moscovici,
1976)
- Emphasis of genetic model on growth and
innovation as basic processes of social life - Social influence doesnt just adapt people to to
a social system - Continual production of system
- Continual change of system
- So, people dont merely conform to systems they
actively participate in and change systems
24Power and Influence (Moscovici, 1976)
- Confusion within earlier social influence
research between power and influence - Power is the basis of social influence
- Those who are dependent conform to those with
power - Influence is a process of submission to social
pressure - Power and influence are alternatives
- Coercion when cant influence
- If can influence, dont need power
25Summary of Moscovicis theoretical framework
- A consistent minority
- Disrupts the established norm
- Produces doubt and uncertainty in majority
- Makes itself visible
- Focuses attention on itself
- Shows that there is an alternative point of view
- Demonstrates certainty, confidence commitment
to the alternative point of view - Does not compromise or move (flexible, not rigid)
- Implies the only solution is for the majority to
accept the minority view.
26Differences between Asch and Moscovici
- Asch and Moscovici viewed conformity differently
- Asch
- conformity as a process to reduce cognitive
uncertainty - Moscovici
- conformity as a process to reduce social conflict
(and people dont like conflict) - Agree to avoid social conflict (nervous, anxious)
27Experimental paradigm
- Moscovici et al (1969)
- Responses to consistent minority influence
- Told female Ss that in colour perception
experiment - Task was to judge the colour of a series of
slides that would vary in intensity of colour and
name this colour aloud when seated in a row of
groups of 6. - In each group there were 2 confederates
- (Control group of 6 naïve Ss).
28Consistent minority influence

Green

Confed 2

29Percent of green responses given by majority Ss
30Variations of theme
- Inconsistent minority
- Sometimes said green in a random order,
regardless of hue of the blue slide - Discrimination task
- Ss had to also later complete 2nd task in private
judging varied colour of slide from green-blue - 3 blue and 3 green
- 10 blue/green
- Slides presented randomly
31RESULTS (of subsequent experiments)
- Inconsistent minority
- 0nly 1.25 said green
- Also, changed order of confederates to being
placed 1st and 4th - No effect
- Discrimination task
- Ss who publicly kept to blue, privately stated
sig more ambiguous blue/green slides as green - So, a public vs. private distinction
- The impact of the consistent minority was greater
at the perceptual than at the public, verbal level
32Comparison of minority and majority influence
- Moscovici Lage (1976)
- Blue-green paradigm, 6 conditions
- Controls respond to stimuli in writing
- (no group influence)
- Consistent minority
- (Same as before 2 confederates, 4 Ss)
- Inconsistent minority
- (Same as before 2 confederates, 4 Ss)
- Consistent minority of 1
- (who went first 1 confederate, 3 Ss)
- Unanimous consistent majority
- (who went first 3 confederates, 1 Ss)
- Non-unanimous consistent majority
- (4 confederates, 2 Ss, varied order)
33Replication of Aschs lines conformity exps
using blue/green paradigm
- But, when tested in private, only the consistent
minority of 2 influenced change of belief
34Majority influence revisited
- Movement to majority position is due to
- The common belief that there is truth in numbers
(informational influence) - Due to the concern for being accepted by those
numbers (normative influence) - Underlying this social influence is a generally
positive judgment of and attraction toward to
majority by those being influenced (Wood et al,
1994)
35Conformity studies of majority influence
- In conformity studies of majority influence (all
others in group are opposed to the subject) - Normative pressures lead to public influence
- Opinion uniformity is valued because it provides
group members with social support for, and
validation of their views (Festinger, 1954) - Dissenters are disliked because they impede group
goals (Levine, 1989) - Informational pressures lead to public and
private influence - So, do minorities have less social influence?
- Or, is it because minorities tend to be disliked
that people do not wish to conform in public?
36Minority vs. majority influences
- Depth of processing (Moscovici Lage, 1976)
- Minority influence deep
- A minority, without obtaining substantial overt
acceptance of its point of view can influence the
basis of other peoples judgements. - Majority influence shallow
- A majority, if unanimous, can make almost all
accept its point of view without affecting the
underlying perceptual-cognitive system.
37Theory of minority conversion
- Moscovici (1980)
- Majorities produce public compliance rather than
conversion - Direct, immediate, temporary effect of social
influence - Minorities challenge beliefs and produce private
conversion - Indirect, delayed, private effect of social
influence
38Dual Process Model
- Majorities induce conformity by means of a public
comparison process - Without giving attention or thought to the issue
itself - (no conversion of attitude)
- Minorities induce conformity by means of a
private validation process - Directed cognitive activity aimed at
understanding why the minority consistently holds
on to its opinion - Attention diverted to the object, a latent
process of conversion as Ss begin to look at the
object as the minority does - (conversion of attitude)
39Evaluation of dual-process model
- WOOD et al. (1994)
- Meta-analysis of 97 studies of minority influence
- 3 kinds of influence were reviewed
- Public judgment change (c.f. compliance)
- Private change on issues directly related to the
appeal (c.f. conversion) - Private change on issues indirectly related to
the appeal (i.e. changes in after-image colour
effects, or indirectly related beliefs)
40Wood et al (1994)
- Found that patterns of influence were consistent
with Moscovicis dual-process model - Minorities measures of influences
- Minorities influence on indirect private
measures - But offered different interpretation of findings
41Wood et als interpretation of results
- Social influence occurs not because of different
cognitive processes - But because Ss dont want to align themselves
with deviant social groups - i.e. studies showed less direct private agreement
when they defined the minority source as a
member of a minority social group (e.g.
homosexual student, or radical feminist)
42Conclusions
- Moscovici raised questions about nature of social
influence - Differences in deep/shallow processing between
minority and majority social influences - Wood et al concluded
- Effects of social influence may not be related to
different levels of processing but may be more
related to social stigma of deviant minorities
