Stanford Prison

b. What are the effects of living in an environment with no clocks, no view of the outside world, and minimal sensory stimulation?

People would go crazy or isolated. They would have mindshock, and feel that 1 day is as long as 1 year. They would stare and sit at one spot all the time.

d. 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?

At first, the body is kinda used to do push up, but as time goes on the body's muscles become weaker in prison so push ups will be harder to do. The guards or other prisoners step on the prisoner's back while he's doing push up. Also, the push up count is increased to several hours later on. Push up is also used in Nazi camps as punishment.
