Required Case Studies

• Asch's research into conformity/variables

  group size- increased but only to a certain number of confederates

  unanimity- dissenter present decreases conformity

  difficulty- harder tasks increase conformity (ISI)
• Asch A03

  pp's were all American men lacks generalisability has androcentrism and ethnocentrism.

  pp's knew they were being investigated may show demand characteristics
• Zimbardo and Social Roles

  Mock prison in stanford university

  21 emotionally stable male pp's

  both roles randomly assigned and given uniform

  Guards heavily followed roles, prisoners became depressed

  ended 8 days early
• Zimbardo A03

  lacks realism to true prison, pp's acted as their stereotypes of roles with lacks generalisability to real prisons.

  Zimbardo may have got too involved, experimenter bias

  Zimbardo had control over key variables and could change them as pleased increasing internal validity and help draw conclusions
• Milgrams investigation on obedience Yale

  Confederate was leaner role, pp's always teacher but did not know

  give shocks for punishment up to 450V, cannot see them

  proximity- press learners hand decreased obey

  location- run down office block decreased obey

  uniform- decreased obey when not in lab coat(authority legitimacy)
• Milgram AO3

  Ethical issues- do no harm and deception

  pp's may not have believed shocks are real, showing demand characteristics, decreasing validity of results.
