In this demonstration/activity (with PowerPoint slides) students are randomly assigned to a high or low arousal group based on the last digit of their social security number. Those in high arousal condition believe they will give a short speech on a randomly selected topic. Those in low arousal condition believe they will merely listen a short speech on a randomly selected topic. Both groups rate the physical attractiveness of several pictures (taken from HotorNot.com) .
During the “Data Analysis” slide instructors can take the time to analyze the data in class if time/facilities permit. Afterward, students have the opportunity to discuss key features of the experiment such as IV, DV, manipulation checks, use of deception, and the importance of experimental control.
