I was a conscientious objector during Viet Nam and worked two years in a mental hospital as my alternative service. I asked one of the psychologists to explain how the patients were different from the staff and she gave me all the psych tests such as the Rohrschach, sentence completion and the TAT so I could compare my answers to the answers of patients that I knew. IME, it doesn't matter whether the patient has seen the images before or not. The proof: we had a patient that was committed by her mother. The law said she had to stay on the ward for 2 weeks and then go before a judge. She told me that she would act totally normally for the 2 weeks so that, when we went before the judge, the staff would look like idiots. She did act totally normally for 2 weeks and when we went before the judge, the first thing he asked her was, "Why are you here?" And she said, "Because I'm the Queen of France."
