Push-ups were a common form of physical punishment imposed by the guards to punish infractions of the rules or displays of improper attitudes toward the guards or institution. When we saw the guards demand push-ups from the prisoners, we initially thought this was an inappropriate kind of punishment for a prison -- a rather juvenile and minimal form of punishment. However, we later learned that push-ups were often used as a form of punishment in Nazi concentration camps, as can be seen in this drawing by a former concentration camp inmate, Alfred Kantor. It's noteworthy that one of our guards also stepped on the prisoners' backs while they did push-ups, or made other prisoners sit or step on the backs of fellow prisoners doing their push-ups.

At first push-ups were not a very aversive form of punishment, but
they became more so as the study wore on. Why the change?
