This dissertation examines rhetorics of heroism and immortality as they are negotiated through a variety of (new) media contexts. The dissertation demonstrates that media technologies in general, and videogames in particular, serve an existential or “death denying” function, which insulates individuals from the terror of mortality. The dissertation also discusses the hero as a rhetorical trope, and suggests that its relationship with immortality makes it a particularly powerful persuasive device. Chapter one provides a historical overview of the hero figure and its relationship with immortality, particularly within the context of ancient Greece. Chapter two examines the material means by which media technologies serve a death denying function, via “symbolic immortality” (inscription), and the McLuhanian concept of extension. Chapter three examines the prevalence of the hero and villain figures in propaganda, with particular attention paid to the use of visual propaganda in the twentieth and twenty-first centuries. Chapter four situates the videogame as an inherently heroic, death denying medium; videogames can extend the player’s sense of self, provide quantifiable victory criteria, and allow players to participate in “heroic” events. Chapter five examines the soldier-as-hero motif as it appears in two popular genres, the First Person Shooter, and Role-Playing Game. Particular attention is paid to the Call of Duty series and The Elder Scrolls V: Skyrim. Chapter six outlines an “epistemological exercise,” which attempts to empirically test the claims made in the previous chapters via Terror Management Theory, an experimental paradigm which examines the relationship between mortality, self-esteem, and ideology. The conclusion discusses how videogames can contest prevailing views of the heroic, and calls for a departure from contemporary game design practices.

Social identity theory (Tajfel & Turner, 1979) is one of the most influential social psychological theories of group behavior and intergroup relations. Early social identity research focused on many different group processes; however, the motivation behind group identification was not fully explored. Researchers have proposed a variety of accounts for why people join and identify with groups. This dissertation unravels the relationship between, on the one hand, mortality salience, self-related uncertainty and self-esteem, and on the other group identification and ingroup defense. The general hypothesis derived from uncertainty-identity theory (Hogg, 2010) is that uncertainty and not fear of death or pursuit of self-esteem motivate people to identify with and defend their groups, and that identification mediates the relationship between uncertainty and defense of the group. Experiment 1 (N = 112) tested the relationship between uncertainty and self-esteem on defense of the ingroup, with the additional test of the mediating effects of identification with the group between uncertainty and ingroup defense. Results showed that uncertainty and not self-esteem motivate people to identify with a group, to defend their group, and that group defense is mediated by identification. Experiment 2 (N = 112) provided a replication of the typical TMT study, which suggests that self-esteem will buffer the effects of mortality salience on ingroup defense, with the additional test of the mediating effects of identification between mortality salience and defense of one's group. As predicted, mortality salience only increased identification and defense of the group when self-esteem was not enhanced, as well, the interactive effects of mortality salience and self-esteem on defense was mediated by identification. Experiment 3 (N = 294) was a combination of both Experiments 1 and 2 and tested the hypothesis that uncertainty would moderate the relationship between self-esteem and mortality salience on group identification and ingroup defense. Exactly as predicted, only under high uncertainty the typical TMT results are demonstrated. Results across these three experiments demonstrate that self-uncertainty plays a significant role in reactions to mortality salience, and support uncertainty-identity theory's analysis of the role of self-uncertainty in ideological conviction and group behavior.

Abstract This thesis addresses the issue of the effects of (repeated) exposure to death-related news content systematically and programmatically through a four-phase research project using a Terror Management Theory (TMT) framework. The central research questions that are posed include, ‘What are the effects for individuals of exposure to death in TV news?’; ‘When will individuals personalise death-related TV news as opposed to feel desensitised to it?’; and, ‘How do individuals cope with repeated exposure to death in TV news?’ The first three chapters provide an extensive literature review that integrates current research from the media effects and mass communication literature with that of experimental findings based on TMT. This leads to an overview of the research program. Then, a series of empirical chapters present findings from six experiments, using a mixed methods approach that incorporates both quantitative and qualitative data and analyses. Finally, in Chapter 9 trends within the quantitative and qualitative data across the studies are discussed along with the theoretical and broader implications of the findings. Overall, there are three primary aims of the research. (1.) To examine a) whether death in news media can prime personal mortality salience, thus eliciting death thought accessibility and cultural worldview fluid compensation defensive outcomes as theorised by TMT (increased nationalism, endorsement of affiliation needs and self-esteem bolstering), and b) whether it is only particular portrayals of death in news media that work this way (i.e., whether there are critical factors such as viewer-victim similarity or level of exposure, as identified in the media effects literature) that play a significant moderating role. (2.) To explore whether it is necessary for the outcomes of exposure to death in news media to be defensive or whether there are alternative and more pro-social outcomes related to the extent that the viewer elaborates cognitively on the content or views more rationally (as implicated in Cozzolino, Staples, Meyers, & Sambceti, 2004). This could be as a function of individual differences (e.g., in cognitive thinking style) or as a function of the situational or contextual factors that prompt one to consider death-related news content more personally (emotionally) versus rationally. (3.) To ask about the “repeated” nature of death primes in news media, given that news media is unique in its daily emphasis on death-related content. Towards this aim we seek to answer the following: Does repeated exposure lead to accentuation of the defensive fluid compensation effects or does it lead to diminished effects because of desensitisation and depersonalisation? This third aim is potentially the most complex and is an under-researched area with important real-world implications. Specifically, Study 1 addresses reactions to death in TV news using a written stimulus task for a range of dependent variables– namely, death thought accessibility, cultural worldview endorsement, and cultural worldview defence. Examining the same dependent variables, Studies 2 and 3 explore the effects of actual TV news footage of a bus crash with multiple fatalities and the role of viewer-victim similarity. Study 4 examines what happens when explicit instructions to imagine your own death are given while watching the same TV news footage. Next, Study 5 examines whether more pro-social effects rather than the typical TMT defensive reactions are possible when a method by Cozzolino et al. (2004) that involves deeper death reflection and the role of cognitive elaboration are explored. Finally, Study 6 addresses the question of repeated exposure to death in TV news, with a focus on whether prior death exposure leads to attenuation or heightening of typical TMT defensive outcomes. Together, results from the six studies indicate that exposure to death-related TV news does not lead inevitably to defensive reactions. While there is strong evidence that death in TV news increases death thought accessibility (especially compared to a non-death TV news control), critically, whether personal mortality salience (as evidenced by self and other death thoughts) is resultant is more variable. Qualitative data shows that people have a range of defensive strategies and resources available to them and that we are honed at detecting personal relevance. Rather than viewing desensitisation as a negative by-product of TV news consumption it seems that the self-protective features of desensitisation are note-worthy. Detachment or neutrality seems to help individuals cope with the barrage of death-related images and sound bytes broadcast via TV news. Conversely, a sensitivity to detect personal relevance helps serve an important surveillance function also geared towards self-protection and meaning making. When there is maximal similarity with the victims of TV news stories portraying death, we can expect viewers to perceive high personal relevance, to personalise news content and to process the content more emotionally, as opposed to feeling desensitised. Although the buffering role of high rational thinking was weak overall, contrary to TMT-based predictions higher rational thinkers were found to be more prone to cultural worldview defence in a number of instances. The theoretical implications for TMT, social identity-based theories, Cozzolino et al.s (2004) work, and relevant media effects literature are discussed. The primary implication for TMT is evidence that death-related TV news footage has the capacity to make personal mortality salient and that higher death thought accessibility often can be evoked by death-related TV news. However, when subsequent measurement of cultural worldview defence is undertaken after a three-minute delay, higher death thought accessibility does not necessarily lead to consistent evidence of defensive fluid compensation effects. These two dependent variables have not been measured together in the literature to date, so these findings provide a significant theoretical distinction for TMT. While death in TV news more likely promotes procreation or family-related defensiveness than national bias, a range of factors (such as detecting self-relevance, viewer-victim similarity, and one’s ability to adopt a rational thinking style) moderate effects in various situations. In particular, factors such as contextual news features, rational thinking, shock value or spontaneous realisation of relevance, and reminders of one’s own family or of one’s own or others’ death are important.

According to Terror Management Theory (TMT; Greenberg, Pyszczynski, & Solomon, 1986) a key function of cultural worldviews is facilitating people's belief that they are different from animals and therefore more than physical creatures fated to obliteration upon death. We sought to investigate the relationship between peoples’ perceived similarity to animals (PSA) and their investment in their ingroup cultural-worldviews, creativity and personal achievement, as ways of managing their awareness of death. We focused on four central hypotheses: (1) high faith in cultural worldviews should reduce PSA; (2) people who view themselves less similar to animals (low-PSA) should be more invested in their cultural worldview, especially after death primes; (3) people who view themselves as more similar to animals (high-PSA), should invest more in personal achievement and creativity as a terror management strategy and (4) be more prone to experience anxiety, particularly after a threat to their creativity. Supporting Hypotheses 1 and 2 we found that: validation of cultural worldviews reduces PSA (Study 1); low-PSA individuals cared more about their ingroup identity and worldviews and perceived other cultures as more different (Studies 2a-2b); after death primes low-PSA individuals defended their groups' cultural worldview more (Studies 3-4), and liked people from other cultures less (Studies 5-6). Hypothesis 3 was partially supported: PSA was positively correlated to importance of creativity, openness and performance on a creativity task (Studies 7, 9 and 10), but it was not correlated with self-reported or projected need for achievement (Studies 7 and 8), or with creative story writing (Studies 8). Hypothesis 4 was also partially supported: PSA was positively related to trait-anxiety (Study 9), and to levels of death thought accessibility (Study 10), and high-PSA individuals experienced more anxiety after receiving negative feedback about their creativity (Study 10). The implications these findings to the field of social psychology are discussed.

Following the 9/11 terror attacks, many Americans experienced some form of habit or mood-altering stress though, most had received their impressions of the violence via distributed media reporting rather than firsthand exposure. Researchers have found that the propagating effects of media broadcasting can exasperate the effects of terror. However, little is known of how reports of terror violence affect group dynamics in geographically distant nations. The purpose of this study, following terror management theory, was to understand if terrorist violence influences cognitive and implicit racial evaluations in a culturally similar, but geographically distant, population. The study's design was a quantitative natural experiment. Time of completing the assessment, either before or after the 2015 Paris Bataclan terror attack, comprised the 2-level independent variable; the dependent variables were the Race Implicit Association Test (IAT) and a cognitive evaluation of racial anxiety. Age and religiosity served as covariates. The target population included White citizen residents of the United States over the age of 18; 263 participants were derived from archival data. Comparisons of raw IAT scores showed an 8% increase in negative implicit racial evaluations following the attack; however, the MANCOVA failed to achieve multivariate significance (p > .05). Despite the lack of statistical significance, important details on implicit racial attitudes were uncovered. Results of this study have the potential to foster positive social change by informing individuals on how their implicit associations might be affected following exposure to reports of terrorist violence. Additionally, these findings may guide national security and intelligence professional's development of post-attack response measures and task forces.

Previous research has found a correlation between death anxiety and self esteem. Researchers have found that both self-esteem and death anxiety play a significant role in an individual's behavior. The purpose of this study was to investigate a correlation, if any, between death anxiety and self esteem using death related scenarios. It was hypothesized the high death anxiety groups will have lower self-esteem than the low death anxiety group, and that the low self-esteem group will have higher death anxiety than the high self-esteem group. Results of an ANOVA indicate that there is a significant difference between the high death anxiety group and low death anxiety group concerning self-esteem. The results also indicate that there is a significant difference between the low self-esteem group and the high self-esteem group concerning death anxiety. Overall it was found that there was significant negative correlation between death anxiety and self-esteem.

To examine how awareness of death (cues) influences believers with implicit and explicit images of Jesus with terror management theory. Previous research has found with terror management theory (TMT), that a persons view of their God provides an understanding of their worldviews and motivations. There is much evidence to suggest that character assessments, or individual differences in personality, are closely tied to people’s facial appearance and their trustworthiness. In this study using TMT, we are able to relate death thoughts to their visual perceptions of Jesus. In over 30 years, empirical research has demonstrated that reminders of morality leads people to defend their worldviews. The purpose of this research was to understand if specific words alluding to death would change how Christian individuals mentally see their Christ in comparison with no priming. We specifically have hypothesized that people who were reminded of death words would illustrate a more positive, empathetic Christ and a more neutral Christ with the lack of priming.
