Problem: Extract the answer to the question from the following context. Question: what did the Dr. give patients for the experiment Context: Stanley Schachter formulated his theory on the earlier work of a Spanish physician, Gregorio Maranon, who injected patients with epinephrine and subsequently asked them how they felt. Interestingly, Maranon found that most of these patients felt something but in the absence of an actual emotion-evoking stimulus, the patients were unable to interpret their physiological arousal as an experienced emotion. Schachter did agree that physiological reactions played a big role in emotions. He suggested that physiological reactions contributed to emotional experience by facilitating a focused cognitive appraisal of a given physiologically arousing event and that this appraisal was what defined the subjective emotional experience. Emotions were thus a result of two-stage process: general physiological arousal, and experience of emotion. For example, the physiological arousal, heart pounding, in a response to an evoking stimulus, the sight of a bear in the kitchen. The brain then quickly scans the area, to explain the pounding, and notices the bear. Consequently, the brain interprets the pounding heart as being the result of fearing the bear. With his student, Jerome Singer, Schachter demonstrated that subjects can have different emotional reactions despite being placed into the same physiological state with an injection of epinephrine. Subjects were observed to express either anger or amusement depending on whether another person in the situation (a confederate) displayed that emotion. Hence, the combination of the appraisal of the situation (cognitive) and the participants' reception of adrenaline or a placebo together determined the response. This experiment has been criticized in Jesse Prinz's (2004) Gut Reactions.

A: adrenaline or a placebo

Since 2004, several buildings have been added, including the DeBartolo Performing Arts Center, the Guglielmino Complex, and the Jordan Hall of Science. Additionally, a new residence for men, Duncan Hall, was begun on March 8, 2007, and began accepting residents for the Fall 2008 semester. Ryan Hall was completed and began housing undergraduate women in the fall of 2009. A new engineering building, Stinson-Remick Hall, a new combination Center for Social Concerns/Institute for Church Life building, Geddes Hall, and a law school addition have recently been completed as well. Additionally the new hockey arena opened in the fall of 2011. The Stayer Center for Executive Education, which houses the Mendoza College of Business Executive Education Department opened in March 2013 just South of the Mendoza College of Business building. Because of its long athletic tradition, the university features also many building dedicated to sport. The most famous is Notre Dame Stadium, home of the Fighting Irish football team; it has been renovated several times and today it can hold more than 80 thousand people. Prominent venues include also the Edmund P. Joyce Center, with indoor basketball and volleyball courts, and the Compton Family Ice Arena, a two-rink facility dedicated to hockey.
