Mortality Salience Motivates the Defense of Environmental Values and Increases Collective Ecoguilt

Modelling associations between mortality salience, environmental concerns, and climate change risk perception in the context of the pandemic

The pandemic and climate change are mortality salience triggers. Environmental issues, attitudes, and climate change risk perceptions were hypothesised to impact how individuals perceived the threat of COVID-19 and climate change during the pandemic. The study explored: 1.) the associations between seeing a link between COVID-19 and climate change and environmental concerns; 2.) the associations between mortality salience and environmental concerns; 3.) the associations between feeling less worried during the pandemic and environmental concerns; and 4.) what these associations tell us about the relationship between mortality salience, the perceived link between COVID-19 and climate change, and feeling less worried during the pandemic. A sample of 665 respondents was achieved from an online survey in 2021. The results of the multiple regression analysis and structural equation modelling showed that environmental issues, attitudes and perceptions, time spent in nature, and climate change risk perception played a role in the extent to which individuals perceived COVID-19 as an indicator of climate change threats, whether mortality salience was made conscious, and whether there was distancing of concern about climate change and social issues during the pandemic. The study makes an important contribution to understanding psychological processes that are activated during disasters that trigger mortality salience, and how this is impacted by the human-nature nexus, and climate change risk perception.

Mortality salience enhances neural activities related to guilt and shame when recalling the past

Mortality salience (MS) influences cognition and behavior. However, its effect on emotion (especially moral emotions) and the underlying neural correlates are unclear. We investigated how MS priming modulated guilt and shame in a later recall task using functional magnetic resonance imaging. The behavioral results indicated that MS increased self-reported guilt but not shame. The neural results showed that MS strengthened neural activities related to the psychological processes of guilt and shame. Specifically, for both guilt and shame, MS increased activation in a region associated with self-referential processing (ventral medial prefrontal cortex). For guilt but not shame, MS increased the activation of regions associated with cognitive control (orbitofrontal cortex) and emotion processing (amygdala). For shame but not guilt, MS decreased brain functional connectivity related to self-referential processing. A direct comparison showed that MS more strongly decreased a functional connectivity related to self-referential processing in the shame than in the guilt condition. Additionally, the activation of insula during MS priming was partly predictive of neural activities related to guilt and shame in the subsequent recall task. Our study sheds light on the psychological and neural mechanisms of MS effects on moral emotions and provides theoretical insights for enriching terror management theory.

Do Salient Social Norms Moderate Mortality Salience Effects? A (Challenging) Meta-Analysis of Terror Management Studies

Terror management theory postulates that mortality salience (MS) increases the motivation to defend one's cultural worldviews. How that motivation is expressed may depend on the social norm that is momentarily salient. Meta-analyses were conducted on studies that manipulated MS and social norm salience. Results based on 64 effect sizes for the hypothesized interaction between MS and norm salience revealed a small-to-medium effect of g = 0.34, 95% confidence interval [0.26, 0.41]. Bias-adjustment techniques suggested the presence of publication bias and/or the exploitation of researcher degrees of freedom and arrived at smaller effect size estimates for the hypothesized interaction, in several cases reducing the effect to nonsignificance (range g_corrected = -0.36 to 0.15). To increase confidence in the idea that MS and norm salience interact to influence behavior, preregistered, high-powered experiments using validated norm salience manipulations are necessary. Concomitantly, more specific theorizing is needed to identify reliable boundary conditions of the effect.

Existential threat as a challenge for individual and collective engagement: Climate change and the motivation to act

The global climate crisis can be perceived as a threat to existential human needs like control, certainty, and personal existence. These threat appraisals elicit an affective state of individual anxiety - one of the strongest motivators of individual pro-environmental behavior and collective policies and activism. Direct action against a threat is associated with other affective approach-motivated states that help to overcome anxiety: Recent findings show collective emotions of anger, guilt, and 'being moved' increase collective engagement but also show a positive relationship between positive activation and individual behavior. Climate threat furthermore promotes palliative responses, such as ingroup defense, identification with nature, or salient common humanity. Here, collective responses seem to reduce anxiety, and when combined with pro-environmental norms, even promote pro-environmental action.

The Impact of Mortality Salience on Intergenerational Altruism and the Perceived Importance of Sustainable Development Goals

The Sustainable Development Goals (SDGs), consisting of 17 specific goals such as ending poverty, reducing inequality, and combating climate change, were proposed by the UN member states in 2014 for the ongoing UN agenda until 2030. These goals articulate the growing need for the international community to build a sustainable future. To progress and build a truly sustainable future requires not only the immediate support of individuals for the current SDGs, but also their personal long-term commitment to the needs of future generations (i.e., intergenerational altruism). Reminders of death can influence attitudes, motivation, and behavior in various aspects of our lives. In the current research, we thus explored whether reminding individuals of their own death will influence their intergenerational altruism and perceived importance of the SDGs. Using a three-condition (mortality salience vs. dentist visit vs. neutral) randomized experiment, we found that mortality salience led participants to place a higher priority on the needs of future generations only when compared to the neutral condition. Further, we conducted a factor analysis that generated two SDGs factors (socially related SDGs and ecologically related SDGs). We found that mortality salience reduced participants' perceived importance of the socially related SDGs when compared to both the dentist visit and the neutral conditions, and mortality salience decreased participants' perceived importance of the ecologically related SDGs only when compared to the neutral condition.
