          • learner has heart condition
            • as teacher moves to 165V experimenter stops
      • learner has heart condition
        • as teacher moves to 165V experimenter stops
    • Model Refusal Condition

      • empathy had no significant difference
      • higher locus of control caused people to stop at 150V or before
    • Evaluation
      • generalisable
        • sample of 70 reduce anomalies
        • sample covers wide age range (20-80 compared to 20-50)

        • script
        • filmed it all
          • inter-rater reliability
      • application
        • increase obedience in schools - wear symbols of authority
        • test people for locus of control as they are more disobedient
      • Validity
        • lacks ecological validity
        • ppts paid before so social pressure made them continue not money threat
        • all based on assumption
      • ethics
        • 2 step screening to remove ppts who have negative reaction to exp
        • told could withdraw at any time
