La mort est l’événement inévitable que la grande majorité des individus souhaite occulter, motivés par une volonté incontestable de continuer à vivre. Parce qu’elle est à la fois source de mystère, de fascination et d’angoisse, cette thématique a fait l’objet de beaucoup d’intérêt en psychologie grâce à la Terror Management Theory (ou théorie de la gestion de la terreur, TMT). Celle-ci permet de rendre compte de la façon dont la peur de la mort est fondamentalement ancrée dans la nature humaine, ainsi que les mécanismes de défense déployés en réponse aux rappels de la perspective de fin de vie suscités par la situation de saillance de mortalité. Ce travail doctoral souhaite compléter la littérature existante sur la TMT en étudiant notamment l’impact de la saillance de mortalité sur le cadrage situationnel, i.e. la mobilisation d’une stratégie d’approche versus d’évitement et les préférences produits promotion versus prévention. Dans cette perspective, une expérimentation a été menée auprès de 360 individus de deux tranches d’âge distinctes (40-59 ans et 60-79 ans). Les résultats obtenus confirment l’existence de deux processus indépendants (approche vs. évitement), de sorte que la manipulation de la saillance de mortalité suscite l’adoption d’une stratégie spécifique et des préférences produits distinctes. Ils montrent également le rôle modérateur fondamental de l’âge chronologique dans ce processus, qui peut s’expliquer notamment par le processus de vieillissement. / Death is the unescapable event that most of individuals want to hide motivated by a fundamental will to stay alive. Because it can be source of mystery, fascination and anxiety, this topic has been of specific interest in psychology thanks to the Terror Management Theory (TMT). This theory enables to understand how fear of death is fundamentally anchored in the human nature and the defense mechanisms that are used in response to death reminders that are aroused by the mortality salience situation. This doctoral research aims at filling the gap in the litterature on TMT while studying specifically the impact of mortality salience on situational regulatory focus, i.e. the adoption of an approach versus avoidance strategy and the preferences for promotion versus prevention products. In this perspective, an experimentation has been conducted among 360 individuals from two distinct age classes (40-59 and 60-79). The results confirm the existence of two independent processes (approach vs. avoidance), so that the mortality salience manipulation leads to the adoption of a specific strategy and distinct product preferences. They also show the main moderator role of chronological age in this process, that can be mainly explained by the aging process.

The aim of the present research was to investigate the issue of loss anxiety within the framework of disability and terror management theory. A questionnaire package was administered to 217 participants twice to examine the effects of mortality salience and disability salience. Besides mortality salience, paralysis salience was found to be effective. Highly conservative participants were becoming more conservative in the paralysis salience and mortality salience conditions. Content analysis was also conducted relating the participants&rsquo / accounts. It was concluded that death and disability were both inducing sadness for the participants. However, this sadness experience could have two different formats. The relation between experimental manipulations and global sadness accounts was not significant. However, the relationship between experimental manipulations and individual sadness accounts was significant. Participants in the mortality salience condition were experiencing less individual sadness than expected. In contrast, participants in the paralysis salience condition were experiencing more individual sadness than expected. It is concluded that death may not be the one and only fundamental fear as terror management theory suggests. Disability might be as fearful as death. A theoretical model is proposed for the alternative experimental manipulation in terror management theory studies. According to this conceptualization, an experimental manipulation could be successful if it satisfies the following three conditions: moderately fearful, highly imaginable/easily available and highly self-relevant. Any kind of loss which satisfies these conditions might result in cultural worldview defense. The threatening nature of disability might provide one more reason relating the importance of a disability-friendly environment.

Terror management theory predicts that when people are reminded of their own mortality (mortality salience), they cling more strongly to cultural worldviews which provide them with a sense of security (Greenberg et al., 1986). For some people, this reaction to mortality salience also involves derogation of, and discrimination against, “other” people and cultures. An increasing tendency towards sensationalism in the news media has resulted in even more frequent reminders of vulnerability and death (e.g., terrorism, violent crime, health and safety concerns). In two experiments involving 868 introductory psychology students, the present research examined the extent to which their (a) support for authoritarian social policies relevant to Canada and (b) authoritarian attitudes in general are influenced by mortality salience. Specifically, right-wing authoritarianism, attachment security, and political orientation were measured in participants in both experiments. Participants were then prompted to think about either their own mortality or about another aversive experience having nothing to do with mortality. Next, participants were asked their opinions regarding authoritarian social policies (Experiment 1) and beliefs indicative of right-wing authoritarianism (Experiment 2). Multiple regression, analysis of variance, and t-tests revealed that individuals with (a) high pre-existing right-wing authoritarian attitudes and (b) conservative political beliefs increased their support for authoritarian social policies following mortality salience (Experiment 1). In contrast, individuals with (a) high attachment security and (b) moderate political beliefs decreased their support for right-wing authoritarian beliefs following mortality salience (Experiment 2), although the former relationship only approached statistical significance. The findings are discussed in terms of their implications for the news media, for social policies and political opinions, and for social justice.

Death, Mortality and Consumer Decision Making: Two Essays Dwayne Scott McGraw ABSTRACT This dissertation presents two essays that address specific aspects of the broad domain of death, mortality and consumer decision making. Essay 1 examines how priming mortality salience (MS) and financial vulnerability (FV) influences insurance policy choices of young, middle aged and senior consumers. Essay 2 investigates how, in funeral planning contexts when consumer may be dealing with significant grief, manipulating choice architecture (via additive vs. subtractive framing of funeral package options) influences the composition and cost of the chosen funeral package. In Essay 1, we use a three-factor design: 2 (MS prime: present/absent) x 2 (FV prime: present/absent) x 3 (Age: Young/Middle-Aged/Senior) to examine how participants evaluate and choose among three hypothetical policies (premium/benefits: low, medium, and high). In a control group (neither prime present), the younger and middle age groups modally select the medium policy whereas the seniors select the high policy. However, the primes affect these choices. When MS alone is primed (FV prime absent), young adults move toward the low policy (assures death benefits at affordable cost). The middle-aged group moves toward the high policy. The seniors remain over-insured with the high policy. When FV is primed, the senior group seems to recognize that their strong financial situation and low obligation levels warrant the medium policy. Interestingly, sensitive to higher financial obligations, the middle-aged tend to buy the high policy. With both MS and FV primed, seniors continue to show affinity toward the medium policy (salience of lower FV tempers the MS effect). Sensitized to their financial situation, younger adults continue to favor the low policy. The middle-aged group remains with the higher policy: both primes have impact. These evaluation data are generally consistent with the choice data. The findings have significant implications for designing life insurance products attuned to the needs of consumers in various age groups. They provide insight into the factors that, if made salient at choice, may facilitate better consumer choices. The results also have important regulatory implications. In Essay 2, we examine if consumers are influenced by how funeral package options are presented at the time of choice. Specifically, we study these effects of choice architecture using manipulations of choice architecture (additive versus subtractive framing of package options). In study1, we examine how grief and related emotions surrounding death influence the effects of additive versus subtractive framing of items. In Study 2, we examine how these effects are moderated by when the funeral is pre-planned or planned at the time of death. These studies shed light on how options framing influence the choice of funeral packages and also the costs and benefits of preplanning funeral events and providing advanced directives for end-of-life care and death related expenses. / Doctor of Philosophy / Death, Mortality and Consumer Decision Making: Two Essays Dwayne Scott McGraw GENERAL AUDIENCE ABSTRACT This dissertation (titled Death, Mortality, and Consumer Decision Making: Two Essays) address specific aspects of the broad domain of death, mortality and consumer decision making. Essay 1 examines how priming mortality salience (MS) and financial vulnerability (FV) influences insurance policy choices of young, middle aged and senior consumers. Essay 2 investigates how, in funeral planning contexts when consumer may be dealing with significant grief, manipulating choice architecture (additive vs. subtractive framing of funeral package options) influences the composition and cost of the funeral package that is ultimately chosen. In Essay 1, we investigate how priming mortality salience (MS), and financial vulnerability (FV) influences the insurance policy choices of young, middle-aged, and senior consumers. These findings show that such priming affects makes the likelihood of death and associated financial needs salient, and differentially influences choice of policies with specific benefit/premium profiles in different age groups. The results provide significant insights for designing life insurance products tailored to the needs of consumers at different life stages and the factors that highlight may influence consumer choices of such products. The results also have regulatory implications. In Essay 2, we examine how coping with grief surrounding death and bereavement may influence consumers' choices of funeral packages. Specifically, we examine the effects of choice architecture (additive versus subtractive framing) on the funeral package that is finally chosen in such situations. In Study 1, we find that both option framing as well as grief and related emotions surrounding the death of a loved one affect the composition and cost of the funeral package that consumers choose. In Study 2, we assess how these effects are influenced by whether the funeral is pre-planned or arranged at the time of death. These studies shed light on how options framing influence the choice of funeral packages and also the costs and benefits of preplanning funeral events and providing advanced directives for end-of-life care and death related expense.

Cette recherche s’intéresse à l’efficacité des registres communicationnels actuels dans une perspective de mobilisation des consommateurs dans la sobriété carbone. Afin d’examiner l’efficacité de ces registres, quatre études ont été menées, i.e. une « méthode-Q » et trois expérimentations. Les deux premières études visent à explorer le rôle des représentations visuelles (i.e. images) et linguistiques (i.e. contenus sémantiques) utilisées pour désigner le changement climatique dans la transmission des préoccupations, des perceptions et des intentions envers la décarbonisation. La troisième étude cherche à expliquer l’effet de l’exploitation de la saillance de mortalité dans ces registres (i.e., anxiogènes vs. informatives) sur les choix de consommation pro-environnementaux (vs. pro-matérialistes). La dernière étude cherche à confirmer qu’une saillance de mortalité, quel que soit son origine (e.g. le changement climatique ou les attaques terroristes) est générateur en majorité des choix de consommation pro-matérialistes (vs. pro-environnementaux). En s’appuyant sur les résultats des ces études, nous mettons en lumière, tout d’abord, la nécessité de modifier ces registres afin de réduire leurs effets négatifs et/ou contreproductifs. Ensuite, la nécessité d’adopter une stratégie de segmentation de la communication selon la vision culturelle du monde dominante des individus pour les engager dans une lutte effective contre le changement climatique. / This research focuses on the effectiveness of climate change communications in order to engage the consumer behaviour in carbon sobriety. To examine this effectiveness, four studies were carried out, i.e., a “Q-method” research and three experiments. The first two studies aim to explore the role of visual representation of climate change and semantic expressions, used to describe this phenomenon in conveying perceptions and attitudes towards decarbonisation. The third study aims to explain the impact of the type of communication (anxiety induced vs. informative) on consumption choices (pro-materialistic vs. pro-environmental). The last study seeks to confirm that mortality salience, whatever its origin is (e.g., climate change or terrorist attacks), generates mostly pro-materialistic consumption choices (vs. pro-environmental). Based on the results of these studies, we highlight, firstly, the necessity to modify these registers in order to reduce their negative and/or counterproductive effects. Secondly, the necessity to adopt a segmentation strategy of communication according to the cultural worldviews of individuals to engage them in an effective fight against the climate changes.

While some individuals experience their work as meaningful, others, with the same job, do not. The purpose of this dissertation is to answer the following question: Why do different individuals, with the same job, view the meaningfulness of their work in conflicting ways? I draw on terror management theory and generativity theory to answer this question by testing the relationship between death awareness and meaningful work. The bulk of academic work concerning meaningful work focuses on its outcomes and few scholars have explained the antecedents of meaningful work. This study aims to extend empirical work of the relationship between death awareness and meaningful.
