Demolishing the Competition: The Association between Competitive Video Game Play and Aggression among Adolescents and Young Adults by Paul J. C. Adachi A thesis Submitted in partial fulfilment of the requirements for the degree Doctor of Philosophy Department of Psychology Brock University St. Catharines, Ontario, Canada April 28, 2015 © Paul Adachi Abstract The link between video game play and aggression is an important issue as video games are the fastest growing form of entertainment in the world. Past research on this association has been focused primarily on the link between video game violence and aggression; however, this research has confounded the effect of video game violence versus competition on aggression. The main goal of the current dissertation, therefore, was to examine the short- and long-term associations between competitive video game play and aggression. In addition, the longitudinal work on this association to date has been limited to adolescent samples, but not young adults. Thus, the second goal of the dissertation research was to investigate whether video game play predicts aggression in the long-term among young adults in addition to adolescents. To address these goals, three studies were conducted. Study 1 consisted of a series of experiments examining the short-term effect of video game violence versus competition on aggression. Study 2 examined the long-term association between competitive video game play and aggression among adolescents, and Study 3 examined this long-term link among young adults, in addition to adolescents. Taken together, the results of the three dissertation studies converged to suggest that video game competition, rather than violence, may be a stronger predictor of aggression in both the short- and long-term. Overall, the current research represents an important advance in our understanding of the association between video game play and aggression, and leads to a new direction in the video game and aggression literature. ii Acknowledgements I am extremely grateful for all of the mentorship and support that I have received from my Ph.D. supervisor Dr. Teena Willoughby. You have played an integral role in my development as a researcher, and I will be forever thankful for your guidance and support. In addition to providing me with excellent training in research and teaching, you helped me persevere through the tough times and you always encouraged me to savor my accomplishments (usually with good wine). I look forward to continuing to collaborate with you throughout my career as a researcher. I am also very thankful for the guidance and support of my Ph.D. committee members, Dr. Gordon Hodson and Dr. Zopito Marini. In addition to receiving excellent feedback and guidance from you regarding my dissertation work, I have had the pleasure of collaborating with each of you on side research projects. You have played a critical role in my development as a researcher, and I hope to continue to collaborate with you in the future. I also would like to thank Dr. Michael Busseri for his dedication to statistical training and mentorship. Through your statistical courses in longitudinal data analysis and structural equation modeling, I developed the knowledge and ability to conduct complicated longitudinal analyses, including those in Study 2 and Study 3 of my dissertation. I am also honored to have been a member of the Adolescent Development Lab. I would like to offer a special thank you to all of the members of this lab, especially Marie Good, Chloe Hamza, Royette Tavernier, Thalia Semplonius, and Tina Brook for all of iii your encouragement and support over the years. I look forward to watching your careers develop and I hope that we continue to collaborate in the future. I want to offer my deepest gratitude to my parents for their unconditional love and support, and their encouragement to pursue my intrinsic interests in psychology. Thank you for always believing in me and for showing me what a strong work ethic is all about. And of course, I want to thank the number 1 person in my life, my loving wife Ashlynn for all of her love and support through this journey. You have put up with many late nights in the lab, research discussions, and even sat through many of my practice presentations. You encouraged me to persevere through the tough times, and you are always excited to celebrate my accomplishments. I can’t imagine the past six and a half years without you. iv Table of Contents Chapter 1: General Introduction…………..…………………………………………........1 Theoretical Background: The Frustration-Aggression
