Dr. Martinez is a social psychologist interested in a hypothesized link between playing violent virtual reality (VR) video games and aggressive decision-making. She recruits 50 college students who identify as regular gamers to participate in her study. The participants are randomly assigned to one of two conditions: In the “violent VR” condition, participants play a violent VR game for two hours a day for two weeks. In the “nonviolent VR condition, participants play a nonviolent VR game for two hours a day for two weeks. After the two weeks, all participants are administered a questionnaire that measures aggressive decision-making. On this questionnaire, higher scores indicate higher levels of aggressive decision-making. She finds that participants in the violent-VR condition scored significantly higher on the questionnaire than participants in the nonviolent-VR condition.
