Now let us look at the actual performance of subjects in the experiment. To begin, we shall consider the results of the Remote-Feedback variation (Experiment 1). It differs slightly from the usual situation in that no vocal complaint is heard from the victim. He is placed in another room where he cannot be seen by the subject, nor can his voice be heard; his answers flash silently on the signal box. However, at 300 volts the laboratory walls resound as he pounds in protest. After 315 volts, no further answers appear, and the pounding ceases.
