Error risk in the decision making process

This research starts from the assumption, widely observed in literature, that stress and distraction involve risks of error, especially in high-density decision making work situations, including Urgent Care -Emergency Departments. Three groups of undergraduates, 20 subjects each, were given fifteen multiple-choice logical questions: one group worked under stress; the second group worked under stress and was distracted twice; the third group worked under conditions that were neither stressful nor disturbing. The highest number of correct answers was generally scored by those working under quiet conditions.
