Social Psychology Flashcards
Group Polarisation
the strengthening of attitudes of individuals when in groups who hold similar attitudes
Group polarisation - empirical evidence
Those without racist views speaking about race issues leads to increased acceptance - and vice versa (Myers & Bishop, 1970)
Judges tend to take the extreme course of action when people are present (65%) vs when they are alone (30%) (Main & Walker, 1973)
Theories why group polarisation occurs
persuasion, comparison, differentiation
Persuation - group polarisation
Changing attitudes due to rational arguments presented by others
Comparison - group polarisation
Change attitude to conform with group norms, especially if they are socially desirable
Differentiation - group polarisation
Alter views to align with the decisions their group should be making
Groups that aren’t affected by group polarisation
Well established groups/ groups discussing well-known problems
Social facilitation
increased performance due to presence of others (Triplett, 1898)
Social inhibition
decreased performance due to presence of others
Triplett, 1898
Yerkes & Dodson (1908)
Perform best with moderate levels of arousal
Simple/well-known tasks - high level of arousal
Difficult/new tasks - low levels of arousal
Diffusion of Responsibility
the assumed reduction in responsibility if others are present
Bystander Effect
the tendency for individuals to be less likely to intervene if others are present
Kitty Genovese Case (1964)
Example of diffusion of responisibility, bystander effect 38 people heard the murder, noone called for help
Darley and Latane (1968)
Diffusion of responsibility, bystander effect - found that all participants who were alone went for help, 85% in first 80 seconds
62% in the group went for help, 31% going quickly
Five Stage Decision Model (1970)
- Notice the situation
- Interpret it as an emergency
- Accept some personal responsibility to intervene
- Consider the best form of intervention
- Decide how to implement their intervention
Stage 1 - 5 stage decision model (1970)
Notice the situation - Darley & Batson (1973): 10% of people who were late assisted, compared to 65% who were early
Stage 2 - 5 stage decision model (1970)
Interpret it as an emergency - Clark & Word (1972): all participants helped, regardless of being in a group when explicitly stated, vs 30% who heard a crash
Stage 3 - 5 stage decision model (1970)
Accept some personal responsibility to intervene - Darley & Latane, 1968
Stage 4 - 5 stage decision model (1970)
Consider the best form of intervention - Cramer et al., 1998 - more help from those trained in 1st aid
Stage 5 - 5 stage decision model (1970)
Decide how to impliment their intervention - Bryan & Test, 1967 - social learning is important
Conformity
tendency to adjust one’s thoughts feelings, and behaviour to be in alignment with those of a certain group/individual; conformity is required in society to established norms, accepted behaviour
Asch (1955) - findings
75% agreed with an incorrect response at least once
33% agreed with incorrect responses 1/2 the time
24% didn’t conform at all
- all reported feeling some degree of self doubt
- those who conformed - aware that their responses were wrong, went along because they didn’t want to hinder results/generate disharmony/conflict
- Felt conspicuous/crazy when they gave the wrong answer
