) What did the authors, McFarland and Carnahan, do to try and get the same kind of people to sign up for their study as the people who signed up for the original Stanford Prison Experiment? (look in the Methods section for this info)

b) The authors found that the participants who signed up for the "prison experiment" scored higher on certain personality traits compared to a control sample of psychology participants - what were these traits? (you may just list them, you will see them listed in several places throughout the paper)

c) What do these authors then conclude regarding situational (external) vs dispositional (internal) explanations of the behavior of the participants in the Stanford Prison Experiment as well as the behavior of the U.S. military personnel involved in events that took place at Abu Ghraib? (look at the Discussion section near the end of the paper.)
