Persons Needed for a Study of Memory
Those who responded to Yale University’s advertisement were told that they would be participating in a study of the relationship between punishment and learning. Each volunteer acted as a teacher, putting questions to a pupil. For each incorrect answer, the teacher was required to give the pupil an electric shock. The intensity of the shock was increased with each mistake, from a 15-volt tingle to a whacking 450 volts.
