Cancer and the threat of death: the cognitive dynamics of death-thought suppression and its impact on behavioral health intentions.

Five studies examined the cognitive association between thoughts of cancer and thoughts of death and their implication for screening intentions. Study 1 found that explicit contemplation of cancer did not increase death-thought accessibility. In support of the hypothesis that this reflects suppression of death-related thoughts, Study 2 found that individuals who thought about cancer exhibited elevated death-thought accessibility under high cognitive load, and Study 3 demonstrated that subliminal primes of the word cancer led to increased death-thought accessibility. Study 4 revealed lower levels of death-thought accessibility when perceived vulnerability to cancer was high, once again suggesting suppression of death-related thoughts in response to conscious threats associated with cancer. Study 5 extended the analysis by finding that after cancer salience, high cognitive load, which presumably disrupts suppression of the association between cancer and death, decreased cancer-related self-exam intentions. Theoretical and practical implications for understanding terror management, priming and suppression, and responses to cancer are discussed.

Mother's milk: an existential perspective on negative reactions to breast-feeding.

Drawing from an existential perspective rooted in terror management theory, four studies examined the hypothesis that breast-feeding women serve as reminders of the physical, animal nature of humanity and that such recognition is threatening in the face of one's unalterable mortality. Study 1 demonstrated that mortality salience (MS) led to more negative reactions toward a scenario depicting a woman breast-feeding her infant in public, and in Study 2, MS decreased liking and increased physical avoidance of a potential task partner described as breast-feeding in another room. Further supporting the hypothesis that such reactions are rooted in threats associated with human creatureliness, MS in conjunction with a breast-feeding prime led to an increase in the accessibility of creaturely related cognitions (Study 3) and priming human/animal similarities (i.e., creatureliness) led to increased negativity toward a magazine cover depicting a woman breast-feeding her child (Study 4). Implications of this research are discussed.

Nostalgia: content, triggers, functions.

Seven methodologically diverse studies addressed 3 fundamental questions about nostalgia. Studies 1 and 2 examined the content of nostalgic experiences. Descriptions of nostalgic experiences typically featured the self as a protagonist in interactions with close others (e.g., friends) or in momentous events (e.g., weddings). Also, the descriptions contained more expressions of positive than negative affect and often depicted the redemption of negative life scenes by subsequent triumphs. Studies 3 and 4 examined triggers of nostalgia and revealed that nostalgia occurs in response to negative mood and the discrete affective state of loneliness. Studies 5, 6, and 7 investigated the functional utility of nostalgia and established that nostalgia bolsters social bonds, increases positive self-regard, and generates positive affect. These findings demarcate key landmarks in the hitherto uncharted research domain of nostalgia.

Reexploring the connection between terror management theory and dissonance theory.

Building upon suggestive earlier findings, the present study sought to test more informatively the notion that reminders of mortality can intensify efforts at dissonance reduction. Toward this end, an induced-compliance experiment was conducted in which participants were given high versus low choice to write a counterattitudinal statement regarding a boring topic under conditions of either mortality salience (MS) or uncertainty salience (control). It was predicted that although dissonance reduction (via attitude change) would be provoked in the control group, MS would significantly exacerbate this effect. These predictions were borne out empirically. The findings, obtained using the historically preeminent paradigm for assessing dissonance reduction, provide firm support for the notion that MS amplifies concerns with cognitive consistency.

Illuminating the dark side of creative expression: assimilation needs and the consequences of creative action following mortality salience.

Previous research indicates that mortality salience and creative behavior combine to increase feelings of guilt, presumably over the disruption to social connection elicited by the call for innovative expression. The present studies examined whether satiating assimilation motives by highlighting conformity to others reduces this effect (Study 1) and facilitates positive psychological engagement (Study 2). Study 1 used a 2 (conformity vs. neutral feedback)x2 (mortality salience vs. control)x2 (creative task vs. noncreative task) design and had participants complete a self-report measure of guilt. Study 2 used a 2 (mortality salience vs. control)x2 (other goal task vs. self-goal task) design, and after a creativity exercise, had participants complete measures of positive mood, vitality, and creative problem solving. Results indicated attending to assimilation needs reduced the elevated guilt that follows the juxtaposition of mortality salience and creative behavior and also increased a sense of positive engagement. Implications are briefly discussed.

Dying to be thin: the effects of mortality salience and body mass index on restricted eating among women.

Following terror management theory, the authors suggest women's striving to attain a thin physique is fueled in part by existential concerns. In three studies, women restricted consumption of a nutritious but fattening food in response to reminders of mortality (mortality salience; MS). When conducted in private (Study 1), this effect was found among women but not men; when replicated in a group setting in which social comparison was likely (Studies 2 and 3), only women who were relatively less successful attaining the thin ideal (i.e., high body mass index; BMI) restricted eating after MS. In Study 3, MS caused high BMI women to perceive themselves as more discrepant from their ideal thinness; this perceived failure mediated the effects of MS and BMI on eating behavior. Findings are discussed from a self-regulatory framework, which considered in the context of pressures for women to be thin, can shed light on health risk behavior.

Firing back at the backfire effect: the influence of mortality salience and nullification beliefs on reactions to inadmissible evidence.

Two studies were conducted to explore psychological factors that contribute to the influence of inadmissible evidence (i.e., the backfire effect) on jurors' verdicts. On the basis of hypotheses derived from terror management theory, we predicted that reminders of mortality, in contrast to an aversive control topic, should lead participants to be less punitive when confronted with inadmissible (as opposed to admissible) evidence, when participants were either situationally induced or dispositionally prone to follow their personal sense of justice. In Study 1, control participants who scored high on a measure of nullification beliefs, and thus were prone to relying on their own sense of justice rather than the law, exhibited the backfire effect. However, reminding participants of their mortality reduced the damaging influence of inadmissible evidence. Study 2 extended these findings by showing parallel effects with a manipulation of nullification proneness via judicial instructions. The implications of these factors on the judicial process are discussed.

Why do people need self-esteem? A theoretical and empirical review.

Terror management theory (TMT; J. Greenberg, T. Pyszczynski, & S. Solomon, 1986) posits that people are motivated to pursue positive self-evaluations because self-esteem provides a buffer against the omnipresent potential for anxiety engendered by the uniquely human awareness of mortality. Empirical evidence relevant to the theory is reviewed showing that high levels of self-esteem reduce anxiety and anxiety-related defensive behavior, reminders of one's mortality increase self-esteem striving and defense of self-esteem against threats in a variety of domains, high levels of self-esteem eliminate the effect of reminders of mortality on both self-esteem striving and the accessibility of death-related thoughts, and convincing people of the existence of an afterlife eliminates the effect of mortality salience on self-esteem striving. TMT is compared with other explanations for why people need self-esteem, and a critique of the most prominent of these, sociometer theory, is provided.

A time to tan: proximal and distal effects of mortality salience on sun exposure intentions.

According to the dual defense model of terror management, proximal defenses are engaged to reduce the conscious impact of mortality salience, whereas thoughts of death outside of conscious awareness motivate distal defenses aimed at maintaining self-esteem. Two experiments examined these ideas by assessing women's intentions to engage in tanning-related behavior. In Study 1, when concerns about death (relative to dental pain) were in focal attention, participants increased intentions to protect themselves from dangerous sun exposure. In contrast, when thoughts about death were outside of focal attention, participants decreased interest in sun protection. In Study 2, participants primed to associate tanned skin with an attractive appearance responded to mortality concerns outside of focal attention with increased interest in tanning products and services. These findings are discussed in relation to the dual-defense model of terror management, societal determinants of self-esteem, and implications for health risk and promotion.

Deliver us from evil: the effects of mortality salience and reminders of 9/11 on support for President George W. Bush.

According to terror management theory, heightened concerns about mortality should intensify the appeal of charismatic leaders. To assess this idea, we investigated how thoughts about death and the 9/11 terrorist attacks influence Americans' attitudes toward current U.S. President George W. Bush. Study 1 found that reminding people of their own mortality (mortality salience) increased support for Bush and his counterterrorism policies. Study 2 demonstrated that subliminal exposure to 9/11-related stimuli brought death-related thoughts closer to consciousness. Study 3 showed that reminders of both mortality and 9/11 increased support for Bush. In Study 4, mortality salience led participants to become more favorable toward Bush and voting for him in the upcoming election but less favorable toward Presidential candidate John Kerry and voting for him. Discussion focused on the role of terror management processes in allegiance to charismatic leaders and political decision making.

Literal and symbolic immortality: the effect of evidence of literal immortality on self-esteem striving in response to mortality salience.

Three studies investigated the effect of encouraging participants to believe in an afterlife on the relationship between mortality salience and self-esteem striving. Participants were exposed to essays arguing either in favor of or against the existence of an afterlife, and reminded about death or a control topic. Mortality salience led to increased accuracy ratings of a positive personality description (Studies 1 and 2) and increased striving for and defense of values (Study 3) among participants who read the essay arguing against an afterlife, but not among participants who read the essay in favor of it. The implications for the terror management analysis of self-esteem, the appeal of immortality beliefs, and the interplay between self-esteem striving and spiritual pursuits are discussed.

In search of the organismic valuing process: the human tendency to move towards beneficial goal choices.

We attempted to test Rogers' concept of the organismic valuing process (OVP) by assessing changes in peoples' goal choices over time. When changes occur, are they more or less random, or do people tend to move towards goals that are more likely to be beneficial, both for themselves and others? "Beneficial" goals were defined as goals typically associated with subjective well-being (SWB) and with prosocial behavior--specifically, we focused on the distinction between intrinsic and extrinsic goal contents. In three studies, participants tended to move towards intrinsic goals and/or away from extrinsic goals over periods ranging from 20 minutes to 6 weeks. These changes were not reducible to social desirability nor to the differing motives underlying differing goal contents, did not vary for persons of different value-types, and had not changed when participants were retested a third time. We conclude that people may have a positive bias toward changing their minds in directions most likely to be SWB enhancing.

Mortality salience and the spreading activation of worldview-relevant constructs: exploring the cognitive architecture of terror management.

Seven experiments assessed the hypothesis derived from terror management theory that reminding people of their mortality would increase accessibility of constructs central to their worldview. Experiment 1 found that mortality primes, relative to control primes, increased accessibility of nationalistic constructs for men but not for women. Experiment 2 replicated this finding and also found that mortality salience increased romantic accessibility for women but not for men. Four subsequent experiments supported the role of unconscious death-related ideation in producing these effects. A final experiment demonstrated that situational primes can increase the accessibility of nationalistic constructs for women after mortality salience. The roles of situational cues and individual differences in the effects of exposure to death-related stimuli on worldview-relevant construct accessibility are discussed.

To belong or not to belong, that is the question: terror management and identification with gender and ethnicity.

The terror management prediction that reminders of death motivate in-group identification assumes people view their identifications positively. However, when the in-group is framed negatively, mortality salience should lead to disidentification. Study 1 found that mortality salience increased women's perceived similarity to other women except under gender-based stereotype threat. In Study 2, mortality salience and a negative ethnic prime led Hispanic as well as Anglo participants to derogate paintings attributed to Hispanic (but not Anglo-American) artists. Study 3 added a neutral prime condition and used a more direct measure of psychological distancing. Mortality salience and the negative prime led Hispanic participants to view themselves as especially different from a fellow Hispanic. Implications for understanding in-group derogation and disidentification are briefly discussed.
