In the Stanford Prison Study, Male College Students Agreed to Participate

In the Stanford prison study, male college students agreed to participate in a two-week experiment to discover what would happen when they took on the roles of prisoners and guards. The researchers found that:

A) within a short time the prisoners became distressed and felt helpless, developing emotional symptoms and physical ailments.
B) about five percent of the guards became tyrannical, giving the prisoners electric shocks when they were slow in obeying their orders.
C) 90 percent of the guards tried to be "tough but fair" and demanded that the tyrannical guards lighten up on the prisoners because it was only a simulation.
D) the study was conducted in an unused wing of a real prison; therefore, the realistic atmosphere enhanced the role behaviour of prisoners and guards.
