  Teacher had to give a stronger shock for each incorrect answer

  Prods were given by the experimenter to keep going
• What was the voltage range?

  Started at 15v and went up to 450v
• What happened at 300v?

  Learner pounded and gave no response
• Findings

  No participants stopped below 300v

  12.5% stopped at 300v

  65% went to the highest 450v

  3 participants had 'full-blown uncontrollable seizures'
• What were the predictions?

  14 psychology students predicted that no more than 3% would go to 450v
• What happened at the end of the study?

  Participants were debriefed - 54% were glad they took part
