The naïve participant was told to read words out loud which the ‘learner’ has been given to memorise. If the ‘learner’ answered correctly with the other word in the pair, the naïve participant was to read the next word. If the ‘learner’ answered incorrectly, the naïve participant was told to deliver an electric shock. Each time an incorrect answer was given, the electric shocks increased by 15v (from 0 all the way up to 450v ‘danger - XXX’).
