First, I would like to thank all the members of my dissertation committee for their invaluable comments and guidance. I would especially like to thank my dissertation chair, Professor Joey George for his superb guidance and wisdom. I would also like to thank Gabe Giordano for his assistance in collecting data for my dissertation. He unselfishly contributed many hours to help with conducting the experiment at the same time that he was working on his own dissertation and teaching. His help was greatly appreciated. I would also like to thank Brian Keane for helping me with my data collection. Another person I would like to thank is Cate Serino for her support as a cohort in going through the doctoral program with me. I appreciate all the experiences and discussions we shared together. Finally, I would like to thank my son, Rick, who brightened my life and gave me encouragement. His love and friendship were instrumental in helping me through this process. I appreciate his contributions to making these years a rich experience. I would also like to thank my parents for their love and support, which helped me immensely in completing my research. iv TABLE OF CONTENTS List of Tables vii List of Figures vii Abstract ix 1.

Deception detection research has expanded to include lies transmitted via computer-mediated communication. Recent studies have only begun to look at the influence of media richness, training, and warning on deception detection accuracy. Studies on the effect of training on deception cue recognition with cross-media comparison are scarce. In addition, few studies have been conducted on the effects of training with warning on deception detection. This study examines the effects of media richness, training, warning, and the combination of training and warning on deception detection accuracy. To test the hypotheses, a laboratory experiment, in which deceivers were interviewed based upon deceptive information in their enhanced resumes, was conducted. Results of the study indicate that training in deceptive cue recognition improves deception detection success. ix CHAPTER 1 INTRODUCTION Deception has a long history in the human experience, from the earliest mythical religious stories of the fallen Archangel lying to Adam and Eve about what would happen to them if they took a bite out of an apple to today’s deceptions surrounding terrorism and the buildup of weapons of mass destruction. Various communication mass media transmit stories of corruption and lies in business and everyday life. It is hard to view television or read a newspaper without learning of someone who created harm through distorting the truth. People have been interested in learning about deception and its detection for many years (Trovillo 1939). Various topics related to deception have been studied, including deception in business practices. Employees’ personal beliefs and attitudes toward lying and the organizational ethical climate are some factors that can influence the prevalence of lies in business (Leonard et al. 2001). Also, people tell more lies when they want to appear likeable or competent, both important aspects for success in business (Feldman et al. 2002). Since deception in business tends to hurt productivity and profitability (Prater et al. 2002), any insights that researchers obtain from the study of deception may have beneficial consequences. For example, auditors can develop a set of heuristics to help them detect financial fraud (Johnson et al. 2001). One area essential to business success is the ability of businesses to hire the most qualified applicants. But research has shown that from 25% to 67% of applicants lie on their resumes and defend these lies in job interviews (Prater et al. 2002). This can be an enormous problem when firms are looking to hire the most qualified applicants (Snell et al. 1999). Detection of deceptive information on resumes is important to improve the interviewing and hiring processes. False information on resumes tends to pertain to the most job relevant items (Becker et al. 1992). For this to be true, applicants must be aware that many companies do not conduct extensive background checks. It is often common knowledge that to compete for jobs, applicants need to present themselves in a positive 1 light. Often, as seen from the above statistics about lies on resumes, applicants cross the line between presenting a positive image and presenting a deceptive image. One example of the perils of real life resume deception is that of Notre Dame football coach George O’Leary who fabricated information on his resume. He said that he had been a letterman and had a football career at the University of New Hampshire, and held a masters’ degree from New York University. After Notre Dame found out about these fabrications, he resigned after only five days on the job (Hughes et al. 2003). Although the above example was a high-profile case, other cases of deception occur that can affect many people and organizations. Hi-technology applicants have more resume fraud than applicants in other industries (Prater et al. 2002). Since technology
