Jerry Burger (2009) replicated Milgram’s experiment with several modifications, implementing which of the following protection?
no subject was allowed to go beyond the 300-volt mark
participants were told two times that they could withdraw from the study at any time and still receive their $50 for participation
participants were monitored by a trained canine psychic
participants were told immediately after the experiment that the “learner” had received only a few minor shocks
