Milgram's procedure (1963)
40 American men volunteered
Paired with a confederate to Milgram
The draw was fixed - participant always teacher + confederate always learner
+ An Experimenter (also a confederate)(dressed in a grey lab coat)
the confederate = 'learn' a set of word pairs and the teacher would test his knowledge
adjacent rooms and teacher positioned in front of a set of controls to administer electric shocks to the learner for each incorrect answer given - reluctance to injure the learner = they were encouraged to continue the procedure
