Disgust as embodied moral judgment

Moral trade-offs reveal foundational representations that predict unique variance in political attitudes

Moral Foundations Theory (MFT) explains variation in moral judgements on the basis of multiple innate, intuitive foundations and has been subject to criticism over recent years. Prior research has tended to rely on explicit self-report in the Moral Foundations Questionnaire (MFQ). In contrast, we seek to capture intuitive choices between foundations in a novel task - the Moral Foundations Conflict Task (MFCT). Across four studies, responses on this task reflect foundations measured by the MFQ (study 1), are not altered under cognitive load or reduced cognitive control (studies 2a and 2b); and explain unique variance in political orientation and related constructs (study 3). Furthermore, using responses and response times generated on the MFCT, we present a computationally explicit model of foundation-related intuitive judgements and show that these patterns are consistent with the theoretical claims of MFT. These findings show that the MFCT outperforms the MFQ and can contribute to the understanding of moral value conflicts, furthering debate on the nature of moral values.

The Relationship Between Face-Based First Impressions and Perceptions of Purity and Compared to Other Moral Violations

A trait labelled as "morality" has been argued to be perceived and prioritised during first impressions of faces; however, immorality is not a homogenous concept. Violations of purity are frequently distinguished from other violations via distinct behavioural and emotional patterns, arguably stemming from physical disgust, sexual content, or "weirdness" impure scenarios. In the current research, participants were asked to rate unfamiliar faces based on social traits and their likelihood of engaging in immoral or nonmoral behaviours. Across two studies, perceived engagement in most autonomy and purity moral violations but also the non-moral sexual and "weird" acts was predicted by lower facial morality. There was also a distinction wherein most purity violations and physical disgust were more associated with male gender, and most autonomy violations with ratings of high dominance. The scenarios also differed within categories, such as sexually impure scenarios and disgust associated with unattractive faces; while behaving "weirdly" and certain other purity violations were associated with low dominance. Taken together, our results suggest faces seemingly low on the trait labelled "morality" are perceived as more likely to engage in most immoral behaviours, but also in other socially relevant, nonmoral behaviours. Social judgements are also not homogenous within or between theory-based categories of moral violations.

Humans: An integrative review exploring dehumanisation in advanced dementia

Background: People living with advanced dementia risk being seen as someone without personhood in contemporary societies, an understanding that has been described and challenged for decades in dementia scholarly literature. Such perception can be characterised as forms of existential dehumanisation, which still asserts itself in dementia care practices, adversely affecting the ethical and caring aspects of such care.Aim: To challenge dehumanisation in dementia care, we must first learn to recognise what foster it in caring relations. Thus, the aim of our study is to identify existing perceptions of care recipients living with advanced dementia, which elicit dehumanising attitudes among formal caregivers.Research design: We conducted an integrative review based on Whittemore and Knafl's updated methodology. This allowed us to identify and analyse 26 articles incorporating both qualitative- and quantitative studies as well as theoretical- and grey literature all describing perceptions of care recipients living with dementia that lead to dehumanisation.Ethical considerations: Studying the darker sides in caring relations was to be beneficial in improving dementia care practices.Findings: Through an analytical process five themes that can sprout dehumanising attitudes in caring relations were identified, which include perceiving people living with advanced dementia as (1) absurd, (2) shadow, (3) perilous, (4) void, or (5) repugnant. We argue that these perceptions can be seen as unintentional and stem from a misled embodied perception, which caregivers should learn to recognise and consequently be able to resist through virtue ethics.Conclusion: Our study indicates that challenging dehumanisation is a practical matter of identifying and reacting in a timely way to ones misled embodied perceptions. We suggest the five themes offer a potential means to warn formal caregivers of impending dehumanising attitudes and help them to review how they ethically are thinking and perceiving the person living with advanced dementia.

The Role of Disgust Certainty in Intuitive Thought Processing: Electrophysiological Evidence

Introduction

The impact of emotions on intuitive and analytical thinking has been widely studied. Most research suggests that negative emotions enhance analytical processing. However, there are studies indicating that the sense of certainty associated with disgust can stimulate intuitive processing. Despite these findings, the neuroelectrophysiological evidence supporting the role of disgust in promoting intuitive processing remains unexplored.

Methods

This study aimed to investigate the neuroelectrophysiological mechanisms by which disgust promotes intuitive processing. A total of 54 participants were recruited and randomly assigned to specific emotion groups. Emotional states were induced by exposing participants to disgust and fear videos designed to evoke specific dimensions of certainty and uncertainty. Event-related potentials (ERP) and the Cognitive Reflection Test (CRT) were utilized as experimental materials to measure participants' responses.

Results

The results demonstrated that disgust facilitated intuitive thinking, as evidenced by the lowest accuracy in behavioral outcomes. ERP findings showed that disgust led to smaller N2 and larger P3b amplitudes under conditions of conflict. These results suggest that disgust reduces individuals' conflict-detection ability, resulting in a stronger sense of certainty in intuitive but incorrect answers.

Conclusion

This study provides neuroelectrophysiological evidence that disgust enhances intuitive thinking. The findings offer a new perspective on the influence of emotions on dual-process thinking, highlighting the role of disgust in shaping intuitive and analytical thought processes.

Emotion-Driven Moral Evaluation: A Mechanistic Study Based on the Drift-Diffusion Model

BACKGROUND

Moral evaluation is identified as the first stage in the theory of moral judgment, and academics believe that it may align with the social intuitionist model. This study aims to prove that the model's emotional dominance hypothesis applies to moral evaluation by presenting a computational decision-making model that mathematically formalizes this emotional dominance decision-making process. We also compared different types of valence evaluation tasks to test the emotional priority hypothesis.

METHODS

We used a convenience sampling method to randomly recruit 30 enrolled college students. The drift-diffusion model was employed to analyze reaction times for words with various emotional and moral valences Additionally, we designed different valence evaluation tasks based on the response relevance hypothesis and evaluated the processing order through reaction time comparisons.

RESULTS

The analysis revealed that the emotional mechanism of immoral evaluation differs from moral evaluation. An increase in emotional valence accelerates the speed of evidence accumulation (v) for moral evaluation (M = 1.21, 0.2% < 0 < 99.8%) but lowers decision caution (a) in immoral evaluation (M = -0.64, 96.1% < 0 < 3.9%). In contrast, moral valence does not have a significant influence on evaluation processes (v, M = -0.28, 72.1% < 0 < 27.9%; a, M = -0.32, 79.3% < 0 < 20.7%). Furthermore, We found no significant difference in reaction times between moral and immoral words in the emotional evaluation task (F(1,29) = 0.55, p = 0.464, partial η2 = 0.02), but a significant difference existed in the moral evaluation task (F(1,29) = 17.99, p < 0.001, partial η2 = 0.38), indicating that the tendency of relatively fast immoral evaluation in emotional evaluation tasks may be caused by emotional priority.

CONCLUSIONS

Our findings support the intuitive model's emotional dominance hypothesis and introduce a new emotional mechanism into moral evaluation. This study clarifies the distinct emotional processes in moral and immoral evaluations, fills a gap in the research on moral evaluation, and offers insights into human decision-making in moral contexts.

Sensitivity to moral and conventional rules in temporal lobe epilepsy

OBJECTIVES

Sensitivity to moral and conventional rules (SMCR) is supported by bilateral brain networks and psychosocial input both of which may be altered in temporal lobe epilepsy (TLE). This study evaluated the components of SMCR in patients with TLE, aiming to clarify their preservation and link to psychopathological and cognitive aspects.

METHODS

Adult patients with unilateral TLE and healthy controls were evaluated using neuropsychological tests for SMCR, memory, language, and executive functions, the Empathy Questionnaire (EQ), and the Symptom Checklist-90-R (SCL-90-R).

RESULTS

The SMCR test items showed good reliability and validity, yielding the Severity and Rules factors distinct from the Executive, Lexical and Memory factors. Patients with right TLE scored worse in moral rules recognition than controls, but this difference was nullified by a significant influence for age and sex. The Severity and Rules factors related to semantic fluency and age and, respectively, TLE side and psychoticism. However, these factors did predict TLE membership.

CONCLUSIONS

In adult patients with TLE, the SMCR test reflects a distinct cognitive domain. Conventional rules are well-retained, while moral reasoning may be only affected in right TLE if unfavorable demographics coexist. Although age, TLE side, semantic abilities, and psychoticism cooperate to determine SMCR, impairment of such domain is not a distinctive feature of TLE.

The fear factor: examining the impact of fear on vaccine hesitancy and anti-vaccine conspiracy beliefs

OBJECTIVES

While anti-vaccine conspiracy beliefs can reduce vaccine intentions, longitudinal research shows that vaccine hesitancy can increase conspiracy beliefs. In three experiments (N = 949), we examined the effect of fear about a vaccine on vaccine hesitancy and anti-vaccine conspiracy beliefs.

METHOD AND MEASURES

In Studies 1a (N = 221) and 1b (N = 508), participants were exposed to high fear (vs low fear) about a (fictional) vaccine before reporting vaccine hesitancy and anti-vaccine conspiracy beliefs. In Study 2, all participants were exposed to high fear before being asked to think about not getting vaccinated (vs vaccinated) against the (fictional) disease. Participants then reported their vaccine hesitancy, anti-vaccine conspiracy beliefs, and closeness to others who distrust official narratives.

RESULTS

In Studies 1a and 1b, exposure to high fear (vs low fear) increased vaccine hesitancy, which was positively correlated with anti-vaccine conspiracy beliefs. The reverse model's effect was either smaller (Study 1a) or non-significant (Study 1b). In Study 2, fear and not wanting to vaccinate resulted in vaccine hesitancy, which then predicted anti-vaccine conspiracy beliefs and feeling closer to those distrusting official narratives.

CONCLUSION

Therefore, fear creates a response not to get vaccinated. A conspiracy belief may then justify this response.

Randomized trial on the effects of an EMDR intervention on traumatic and obsessive symptoms during the COVID-19 quarantine: a psychometric study

Introduction

It has been suggested that the COVID-19 pandemic was a potentially traumatic occurrence that may have induced generalized anxiety and discomfort, particularly in susceptible populations like individuals with mental illnesses. The therapeutic approach known as eye movement desensitization and reprocessing (EMDR) has been shown to be successful in helping patients process traumatic events and restore wellbeing. Nevertheless, little is known about the precise processes through which EMDR fosters symptom recovery.

Methods

In order to disentangle these issues, we conducted a randomized controlled trial (ClinicalTrials.gov Identifier NCT06110702) with 107 participants who were selected from university hospitals as a sample of investigation. Random assignments were applied to the participants in order to assign them to the experimental and control groups. The experimental group, but not the control group, underwent an 8-week EMDR intervention. Body perception, disgust, and emotions of guilt and shame, as well as mental contamination and posttraumatic and obsessive-compulsive symptoms, were investigated before and after the EMDR intervention.

Results

The EMDR intervention was able to improve all of the variables investigated. Path analysis showed that body perception was able to predict both disgust and emotions of guilt and shame. Disgust was able to predict both mental contamination and obsessive-compulsive symptoms, while guilt and shame were able to predict post-traumatic symptoms.

Conclusions

EMDR is an effective therapy for the treatment of post-traumatic and obsessive symptoms that acts through the promotion of improvement of the emotions of guilt/shame and disgust, respectively. Implications for clinical practice are examined.

People who seem disgusting seem more immoral

Despite unresolved questions about replicability, a substantial number of studies find that disgust influences and arises from evaluations of immoral behavior and people. Departing from prior emphases, the current research examines a novel, related question: Are people who are viewed as disgusting (i.e., people whose habits seem disgusting) perceived as more immoral than typical or unusual people? Four experiments examined this, also exploring the downstream impacts of moral character judgments. Adults who seemed disgusting were regarded as more immoral for purity and non-purity violations (Experiment 1) and less praiseworthy for prosocial acts (Experiment 2). In Experiment 3, an 8-year-old with typical (but seemingly disgusting) habits was rated as "naughtier" and likelier to misbehave than an atypical child who loved vegetables and disliked sweets. Experiment 4 revealed how, when no behavioral information is available, beliefs about target disgust influence beliefs about future behavior, helping explain why seemingly disgusting targets are viewed as more immoral, but not always more punishable for their bad behavior.

Disgust as a basic, sexual, and moral emotion

Disgust is a basic emotion that increases the organism's survival success by preventing the transfer of pathogens. In this regard, it directs cognitive processes and motivates avoidance behaviors that prevent pathogens from entering the body. Moreover, disgust has many specific characteristics that distinguish it from other basic emotions. Firstly, unlike other basic emotions, it contaminates neutral objects around it and causes difficult-to-change learning. Another specific characteristic of disgust is that it depends on ideational processes. Objects, situations, and behaviors that do not contain pathogens can also cause disgust. In this regard, disgust appears not only as a basic emotion but also as different adaptations in different fields. In this context, two distinct adaptations of disgust stand out: sexual and moral disgust. These two adaptations of disgust benefit from disgust-related behaviors and motivations in different ways. Sexual disgust works as a gene protection mechanism, while moral disgust helps maintain social rules. The specific characteristics of disgust and its effects on cognitive processes such as attention and memory interact. In conclusion, the multifaceted structure of disgust shows that it needs to be studied more in the subfields of psychology. (Strohminger, Philos Compass 9:478-493, 2014) defines disgust as a psychological nebula that needs to be discovered. However, it is observed that disgust has not been adequately addressed. This review aims to comprehensively explore unique characteristics and diverse aspects of disgust, shedding light on its significance from various perspectives. This study underscores the broader understanding of disgust and its pivotal role in psychological research.

Within your rights: Dissociating wrongness and permissibility in moral judgement

Are we ever morally permitted to do what is morally wrong? It seems intuitive that we are, but evidence for dissociations among judgement of permissibility and wrongness is relatively scarce. Across four experiments (N = 1438), we show that people judge that some behaviours can be morally wrong and permissible. The dissociations arise because these judgements track different morally relevant aspects of everyday moral encounters. Judgements of individual rights predicted permissibility but not wrongness, while character assessment predicted wrongness but not permissibility. These findings suggest a picture in which moral evaluation is granular enough to express reasoning about different types of normative considerations, notably the possibility that people can exercise their rights in morally problematic ways.

Disgust Processing and Potential Relationships with Behaviors in Autism

PURPOSE OF REVIEW

While there are reports of differences in emotion processing in autism, it is less understood whether the emotion of disgust, in particular, plays a significant role in these effects. Here, we review literature on potential disgust processing differences in autism and its possible associations with autistic traits.

RECENT FINDINGS

In autism, there is evidence for differences in physical disgust processing, pica behaviors, attention away from other's disgust facial expressions, and differences in neural activity related to disgust processing. In typically developing individuals, disgust processing is related to moral processing, but modulated by individual differences in interoception and alexithymia. Autistic individuals may experience atypical disgust, which may lead to difficulty avoiding contaminants and affect socio-emotional processing. In autism, such outcomes may lead to increased occurrences of illness, contribute to gastrointestinal issues, diminish vicarious learning of disgust expression and behaviors, and potentially contribute to differences in processes related to moral reasoning, though further research is needed.

Little Evidence for the Role of Disgust Sensitivity in Implicit Disgust to Images of White People Engaged in Injecting Drug Use (IDU)

Background: Previous research has shown that People Who Inject Drugs (PWID) are subject to public stigma, which affects access to, and provision and quality of, treatment and support services. Less is known about the socio-cognitive processes that support the development and maintenance of public stigma toward PWID. The present study investigated the role of disgust sensitivity in implicit disgust to injecting drug use. Methods: 126 participants took part in an online Implicit Association Task (IAT) measuring implicit disgust to pictorial stimuli of injecting drug use or medical injecting. Participants also completed The Disgust Scale Revised, Injecting Phobia Scale (Short Form), Attitudes to People Who Use Drugs (PWUD) scale and a substance use inventory. Results: Average IAT score was negative indicating significantly higher implicit disgust to injecting drug use. Hierarchical linear regression found that injecting phobia predicted implicit disgust to injecting drug use. Questionnaire measures of disgust did not predict implicit disgust. While animal reminder disgust and injecting phobia were significantly correlated with each other, animal reminder disgust did not predict implicit disgust scores. Conclusions: On the basis of our findings, stigma toward PWID may not be a result of feelings of disgust toward injecting drug use. We discuss findings in the context of the underlying cortical processes supporting implicit and explicit representations of disgust. Future research should seek to investigate neurophysiological evidence for disgust to and stigmatization of injecting drug use and the potential role of domains of disgust in this.

The Problem of Purity in Moral Psychology

Academic AbstractThe idea of "purity" transformed moral psychology. Here, we provide the first systematic review of this concept. Although often discussed as one construct, we reveal ~9 understandings of purity, ranging from respecting God to not eating gross things. This striking heterogeneity arises because purity-unlike other moral constructs-is not understood by what it is but what it isn't: obvious interpersonal harm. This poses many problems for moral psychology and explains why purity lacks convergent and divergent validity and why purity is confounded with politics, religion, weirdness, and perceived harm. Because purity is not a coherent construct, it cannot be a distinct basis of moral judgment or specially tied to disgust. Rather than a specific moral domain, purity is best understood as a loose set of themes in moral rhetoric. These themes are scaffolded on cultural understandings of harm-the broad, pluralistic harm outlined by the Theory of Dyadic Morality.

How does disgust regulate social rejection? a mini-review

The need to belong is a fundamental aspect of human nature. Over the past two decades, researchers have uncovered many harmful effects of social rejection. However, less work has examined the emotional antecedents to rejection. The purpose of the present article was to explore how disgust--an emotion linked to avoidance and social withdrawal--serves as an important antecedent to social rejection. We argue that disgust affects social rejection through three routes. First, disgust encourages stigmatization, especially of those who exhibit cues of infectious disease. Second, disgust and disease-avoidance give rise to cultural variants (e.g., socially conservative values and assortative sociality), which mitigate social interaction. Third, when the self is perceived as a source of contamination, it promotes shame, which, subsequently, encourages withdrawal from social interaction. Directions for future research are also discussed.

Does multisensory stimulation with virtual reality (VR) and smell improve learning? An educational experience in recall and creativity

Purpose

The purpose of this paper is to derive into practical recommendations from multisensory stimulation with virtual reality (VR) and scent to help educators develop effective teaching strategies geared toward aspects of the learning experience, recall, and creativity in a stereotypical learning context.

Design/methodology/approach

The paper is based on a randomized experiment in which student participants were subdivided into three treatment groups and one control group. Each group was stimulated by a different combination of visual, auditory, and olfactory stimuli (2D SMELL, VR, and VR SMELL) and the outcomes were compared against those of the control group (2D). Consistent with the Cognitive Theory of Multimedia Learning, hypotheses were constructed to study the effect of different combinations of stimuli on the learning experience and learning outcomes related to recall and creativity in a stereotypical learning context.

Findings

Traditional video content alone and bundled with a coherent olfactory stimulus prompted higher self-reported ratings of perceived quality of the sensory experience. Olfactory stimulus in combination with either VR or a traditional video prompted higher self-reported ratings on perceived immersion. In a stereotypical learning context, the highest recall scores were achieved with traditional video alone. Both VR alone and bundled with an olfactory stimulus resulted in enhanced creativity.

Research limitations/implications

The findings of this study should be interpreted in the context of adopting multisensory stimulations combined with VR technology as part of stereotypical learning contexts. Most professional educators do not have robust knowledge or experience in using build-on-purpose multisensory stimuli but are increasingly engaged in using multisensory tools such as VR, as part of their teaching practice. In relation to recall, the results are consistent with the hypothesis that in a stereotypical learning context, a multisensory experience involving VR and olfactory stimuli can be related to an undesired cognitive load for learners. There exists a possibility that the low-technical version of the VR goggles used, as well as the contents of the instructional video may have influenced the learning outcomes in terms of recall. Hence, future research should consider such aspects and focus on richer learning contexts.

Originality/value

This work offers practical recommendations for instructional design strategies aiming to create multisensory stimulations with VR and olfactory components to foster a richer learning experience and enhanced learning outcomes, under the assumptions of a stereotypical learning context.

Pandemic elevates sensitivity to moral disgust but not pathogen disgust

The behavioral immune system, with disgust as its motivational part, serves as the first line of defense in organisms' protection against pathogens. Laboratory studies indicate that disgust sensitivity adaptively adjusts to simulated environmental threat, but whether disgust levels similarly change in response to real-life threats, such as a pandemic, remains largely unknown. In a preregistered within-subject study, we tested whether the threat posed by the Covid-19 pandemic would lead to increased perceived disgust. The perception of threat was induced by testing during two phases of the Covid-19 pandemic (periods of high vs. low pathogen threat). We found heightened levels of moral disgust during a "wave" of the pandemic, but the effect was not observed in the domain of pathogen or sexual disgust. Moreover, the age of respondents and levels of trait anxiety were positively associated with pathogen and moral disgust, suggesting that variation in disgust sensitivity may be based chiefly on stable characteristics.

The role of emotional awareness in evaluative judgment: evidence from alexithymia

Evaluative judgments imply positive or negative regard. But there are different ways in which something can be positive or negative. How do we tell them apart? According to Evaluative Sentimentalism, different evaluations (e.g., dangerousness vs. offensiveness) are grounded on different emotions (e.g., fear vs. anger). If this is the case, evaluation differentiation requires emotional awareness. Here, we test this hypothesis by looking at alexithymia, a deficit in emotional awareness consisting of problems identifying, describing, and thinking about emotions. The results of Study 1 suggest that high alexithymia is not only related to problems distinguishing emotions, but also to problems distinguishing evaluations. Study 2 replicated this latter effect after controlling for individual differences in attentional impulsiveness and reflective reasoning, and found that reasoning makes an independent contribution to evaluation differentiation. These results suggest that emotional sensibilities play an irreducible role in evaluative judgment while affording a role for reasoning.

Disgusting Democrats and Repulsive Republicans: Members of Political Outgroups Are Considered Physically Gross

The status of disgust as a sociomoral emotion is debated. We conducted a stringent test of whether social stimuli (specifically, political outgroup members) can elicit physical disgust, as distinct from moral or metaphorical disgust. We employed stimuli (male faces) matched on baseline disgustingness, provided other ways for participants to express negativity toward outgroup members, and used concrete self-report measures of disgust, as well as a nonverbal measure (participants' facial expressions). Across three preregistered studies (total N = 915), we found that political outgroup members are judged to be "disgusting," although this effect is generally weaker for concrete self-report measures and absent for the nonverbal measure. This suggests that social stimuli are capable of eliciting genuine physical disgust, although it is not always outwardly expressed, and the strength of this result depends on the measures employed. We discuss implications of these results for research on sociomoral emotions and American politics.

Defensive emotions and evaluative judgements: Sensitivity to anger and fear predicts moral judgements, whereas sensitivity to disgust predicts aesthetic judgements

Aesthetic and moral evaluations engage appetitive and defensive emotions. While the role played by pleasure in positive aesthetic and moral judgements has been extensively researched, little is known about how defensive emotions influence negative aesthetic and moral judgements. Specifically, it is unknown which defensive emotions such judgements tap into, and whether both kinds of judgement share a common emotional root. Here, we investigated how participants' individual sensitivity to disgust, fear, anger and sadness predicted subjective judgements of aesthetic and moral stimuli. Bayesian modelling revealed that participants who were more sensitive to anger and fear found conventional and moral transgressions more wrong. In contrast, participants who were more sensitive to disgust disliked asymmetrical geometric patterns and untidy rooms more. These findings suggest that aesthetic and moral evaluations engage multiple defensive emotions, not just disgust, and that they may rely on different defensive emotions as part of their computational mechanism.

Awe promotes moral expansiveness via the small-self

The experience of awe has been shown to challenge how people think about themselves and the world around them, linking them to something greater than themselves. We investigated whether this emotional experience of awe may also challenge the boundaries of our moral consideration, leading to a generalized expansion in our moral worlds. Across five studies (N = 990), we examined whether awe might promote moral expansiveness; that is, increased moral concern across a broad range of entities (e.g., out-groups, animals, plants, environments). Cross-sectional Studies 1a and 1b, found dispositional awe was related to greater moral expansiveness. Experimental Studies 2 and 3, using video-induced awe, found consistent indirect effects on moral expansiveness, via self-reported awe and the small-self sense of vastness. Experimental Study 4, using Virtual Reality induced awe, found those in the awe condition (vs. control) reported greater moral expansiveness, and this was fully mediated by the small-self sense of vastness. Our findings show awe expands our sense of connectedness to the broader world, and through this, increases the breath of our moral concern.

Assessing the factors that influence the donation of a deceased family member's organs in an opt-out system for organ donation

RATIONALE

Family, and sometimes longstanding friends, have considerable influence over organ donation, through agreeing or disagreeing to the donation of a deceased individual's organs. To date, most research has been undertaken within opt-in systems.

OBJECTIVE

This study advances on previous research by assessing next-of-kin approval under opt-out legislation. We tested whether next-of-kin approval varies when the deceased is a registered donor (opted-in), registered non-donor (opted-out) or has not registered a decision under an opt-out policy (deemed consent). We also tested if the deceased's wishes influenced next-of-kin approval through relatives anticipating regret for not donating and feelings of uncertainty. Finally, we assessed whether next-of-kin's own beliefs about organ donation influenced whether they followed the deceased's wishes.

METHODS

Participants (N = 848) living in a country with opt-out legislation (Wales, UK) were asked to imagine a relative had died under an opt-out system and decided if their relatives' organs should be donated. Participants were randomly allocated to imagine the deceased had either (i) opted-in, (ii) opted-out or (iii) not registered a decision (deemed consent). The outcome variable was next-of-kin approval, with uncertainty and anticipated regret as potential mediators and next-of-kin's beliefs about organ donation as moderators.

RESULTS

Next-of-kin approval was lower when the deceased had opted-out than under deemed consent. This was due to next-of-kin anticipating more regret for not donating under deemed consent than opt-out. Further analyses revealed the deceased's wishes influence next-of-kin approval, via anticipated regret, when next-of-kin did not hold negative beliefs about organ donation.

CONCLUSIONS

The deceased's wishes were less likely to be followed when next-of-kin had negative beliefs towards donation. Developing large-scale campaigns to improve these beliefs in the general public should make people more likely to follow the deceased's wishes. As a result, these campaigns should improve the availability of donor organs.

Opposite effects of estradiol and progesterone on woman's disgust processing

Background

Ovarian hormones play a critical role in emotion processing, which may be a major reason for the high rates of major depressive disorders in women. However, the exact roles of estradiol and progesterone in emotional processing remain unclear. To this end, we performed behavioral and rs-fMRI studies on the effects ovarian hormones on disgust emotion.

Methods

In Experiment 1, 95 Chinese female undergraduates completed the single category implicit association test (SC-IAT) and explicit measures of disgust intensity task, 32 in the menstrual phase, 30 in the follicular phase, and 33 in the luteal phase. In Experiment 2, A total of 25 healthy female undergraduates completed three sessions of the rs-fMRI. The menstrual group was scanned during cycle days 2-5, the follicular group during cycle during days 10-13, and the luteal group was scanned 3-7 days before the next menstruation.

Results

The behavioral results showed that women during the luteal phase had higher D scores and shorter response times (RTs) to disgust stimuli compared to the menses and follicular phases. In contrast, women during the follicular phase had fewer feelings of disgust and longer RTs to pathogen stimuli compared with that during the menses and luteal phases, but this effect was moderated by the intensity of the stimuli. rs-fMRI studies showed that women during the luteal phase have higher functional connectivity in the salience network than those in the follicular phase. Compared with the menstrual phase, women have lower functional connectivity in the amygdala during the follicular phase.

Conclusion

In summary, a more negative attitude to disgust stimuli and the enhanced functional connectivity of the salience network during the luteal phase may be associated with high progesterone levels, whereas lower disgust feelings and reduced functional connectivity of the amygdala during the follicular phase may be associated with high estradiol levels.

Specificity Versus Generality: A Meta-Analytic Review Of The Association Between Trait Disgust Sensitivity And Moral Judgment

Disgust seems to play an important role in moral judgment. However, it is unclear whether the role of disgust in moral judgment is limited to certain kinds of moral domains (versus many) and/or certain types of disgust (versus many). To clarify these questions, we conducted a multilevel meta-analysis ( k = 512; N = 72,443) on relations between trait disgust sensitivity and moral judgment (disgust-immorality association). Main analyses revealed a significant overall mean disgust-immorality association ( r = .23). Additionally, moderator analyses revealed significant specificity in disgust type and moral domain (grounded in Moral Foundations Theory): effects were stronger for (a) sexual disgust compared to pathogen disgust, (b) sanctity moral judgments compared to other domains of moral judgments, and (c) sexual-sanctity associations compared to other disgust type-moral domain pairings.

Do we enjoy what we sense and perceive? A dissociation between aesthetic appreciation and basic perception of environmental objects or events

This integrative review rearticulates the notion of human aesthetics by critically appraising the conventional definitions, offerring a new, more comprehensive definition, and identifying the fundamental components associated with it. It intends to advance holistic understanding of the notion by differentiating aesthetic perception from basic perceptual recognition, and by characterizing these concepts from the perspective of information processing in both visual and nonvisual modalities. To this end, we analyze the dissociative nature of information processing in the brain, introducing a novel local-global integrative model that differentiates aesthetic processing from basic perceptual processing. This model builds on the current state of the art in visual aesthetics as well as newer propositions about nonvisual aesthetics. This model comprises two analytic channels: aesthetics-only channel and perception-to-aesthetics channel. The aesthetics-only channel primarily involves restricted local processing for quality or richness (e.g., attractiveness, beauty/prettiness, elegance, sublimeness, catchiness, hedonic value) analysis, whereas the perception-to-aesthetics channel involves global/extended local processing for basic feature analysis, followed by restricted local processing for quality or richness analysis. We contend that aesthetic processing operates independently of basic perceptual processing, but not independently of cognitive processing. We further conjecture that there might be a common faculty, labeled as aesthetic cognition faculty, in the human brain for all sensory aesthetics albeit other parts of the brain can also be activated because of basic sensory processing prior to aesthetic processing, particularly during the operation of the second channel. This generalized model can account not only for simple and pure aesthetic experiences but for partial and complex aesthetic experiences as well.

A Dual-Process Approach to Moral Panic and Public Support for Sex Offender Management Policies

The current study explores if and how dual-process thinking styles (System I/experiential and System II/rational processing) predict and explain the degree to which members of the public express moral panic toward and support for existing sex offender management policies (registration, notification, residence restrictions), regardless of their efficacy or effects on recidivism rates, for different types of individuals who commit sex offenses (sex offender, juvenile sex offender, cybersex offender, female sex offender, rapist, child molester). Online experimental methods were used with a lay sample (N = 324). Results show that the extent to which participants exhibited a reliance on System I processing significantly predicted their feelings of moral panic (concern, hostility, and volatility) toward individuals classified as child molesters. Further, feelings of concern, hostility, and volatility, as significant predictors of support for existing sex offender management policies for individuals classified as child molesters, were found to increase as a function of participants' reliance on the System I, experiential thinking style. Implications of this work, specifically related to addressing public support for existing sex offender management policies for individuals classified as child molesters, are discussed.

A tale of two cities: emotion and reason in the formation of moral judgement and possible metaethical implications

The project of naturalizing ethics has multiple contributions, from cognitive and moral psychology to primatology, neuroscience or evolutionary theory. One of the strategies for naturalizing ethics has been to argue that moral norms and values can be explained away if we focus on their causal history, if it is possible to offer both an ultimate and proximate causal explanation for them. In this article, I will focus on the contribution of cognitive and moral psychology as a way of offering a proximate causal explanation for moral judgments. I am mostly interested in understanding to what extent these cognitive and psychological questions have some bearing in the fields of ethics and meta-ethics. Does this research programme put at stake the contention that ethics is a manifestation of human rationality? Is it true that finding the cognitive underpinnings of some of our moral judgments vindicates some meta-ethical position, namely some kind of reductionist naturalism? In the end, I will argue that even if scientific disciplines such as cognitive psychology give us a naturalized picture of the moral agent, there seem to be no reasons to think that from a naturalized perspective of the agent capable of perceiving value it must follow the naturalization of value itself.

How Stable are Moral Judgments?

Psychologists and philosophers often work hand in hand to investigate many aspects of moral cognition. In this paper, we want to highlight one aspect that to date has been relatively neglected: the stability of moral judgment over time. After explaining why philosophers and psychologists should consider stability and then surveying previous research, we will present the results of an original three-wave longitudinal study. We asked participants to make judgments about the same acts in a series of sacrificial dilemmas three times, 6-8 days apart. In addition to investigating the stability of our participants' ratings over time, we also explored some potential explanations for instability. To end, we will discuss these and other potential psychological sources of moral stability (or instability) and highlight possible philosophical implications of our findings.

Effects of Core Disgust and Moral Disgust on Moral Judgment: An Event-Related Potential Study

Core disgust is elicited by physical or chemical stimuli, while moral disgust is evoked by abstract violations of moral norms. Although previous studies have pointed out these two types of disgust can affect behavior and spatial dimensions of moral judgment, less is known about how moral and core disgust affect the temporal neural processing of moral judgment. In addition, whether moral and core disgust are only related to purity-based moral judgment or all kinds of moral judgment is still controversial. This study aimed to explore how core and moral disgust affect the neural processing of purity-based moral judgment by using affective priming and moral judgment tasks. The behavioral results showed that the severity of moral violation of non-purity ones is higher than purity ones. The event-related potentials (ERP) results mainly revealed that earlier P2 and N2 components, which represent the automatic moral processes, can differentiate neutral and two types of disgust rather than differentiating moral domain, while the later N450, frontal, and parietal LPP components, which represent the conflict detection and, later, cognitive processing can differentiate the purity and non-purity ones rather than differentiating priming type. Moreover, core and moral disgust priming mainly differed in the purity-based moral processing indexed by parietal LPP. Our findings confirmed that the disgusting effect on moral judgments can be explained within the framework of dual-process and social intuitionist models, suggesting that emotions, including core and moral disgust, played an essential role in the automatic intuition process. The later parietal LPP results strongly supported that core disgust only affected the purity-based moral judgment, fitting the primary purity hypothesis well. We show how these theories can provide novel insights into the temporal mechanisms of moral judgment.

Serial reproduction of narratives preserves emotional appraisals

We conducted the largest multiple-iteration retelling study to date (12,840 participants and 19,086 retellings) with two different studies that test how emotional appraisals are transmitted across retellings. We use a novel Bayesian model that tracks changes across retellings. Study 1 examines the preservation of appraisals of happy and sad stories and finds that retellings preserve the story's degree of happiness and sadness even when length shrinks and aspects of story coherence and rationalisation deteriorate. Study 2 compared the transmission of appraisals of happiness and sadness with embarrassment, disgust, and risk. Appraisals of happiness, sadness, and also embarrassment showed high appraisal preservation, while disgust and risk were not well preserved. We conclude that participants in our studies encoded happy and sad stories by encapsulating the events and details into an overall emotional appraisal of the story and that this processing strategy might also apply to stories involving other emotions like embarrassment. The emotional appraisal played a key role in retelling by helping to guide the selection, invention, and ordering of the story elements. Hence, we posit that emotion appraisals can operate as anchors for remembering and retelling stories, thus playing an important role in narrative communication.

Why must we rush to bury our dead (pigs): The option of excarnation by exposure

The accepted paradigm of foreign animal disease preparedness in Canada, the emergency for which to prepare, starts with identification of the exotic viral agent in a Canadian farm animal population. This narrative focuses on the containment of the infectious agent, within diseased animals, on infected premises. Framing the emergency as a disease incursion limits rational imagination to only one version of one potential animal emergency. This framing of the problem directs the carcass disposal solutions to consider only methods to dispose of viral infected material. However, in all documented responses to catastrophic swine diseases in the past three decades, the number of uninfected animals caught up in movement control zones and killed greatly exceeds the number of infected animals killed. The temporary closures of slaughterhouses in spring 2020 due to COVID-19 transmission resulted in thousands of healthy market hogs surplus to market; an unanticipated emergency of healthy pigs. This paper proposes an alternate carcass disposal option for material from uninfected farms. "Excarnation by exposure" is a natural process of debulking and dehydrating carcasses by blow fly larvae, mitigating financial costs of final disposal. Excarnation by exposure is a reasonable and possibly necessary additional option for the management of uninfected carcasses in a catastrophic emergency response in commercial pigs.

Omission bias in children's and adults' moral judgments of lies

This study examined whether omission bias occurs in moral judgments of lies. Omission bias is the tendency to judge acts of commission as morally worse than equivalent acts of omission. Children aged 8 and 9 years (third graders) and 11 and 12 years (sixth graders), as well as adults, made moral judgments about lies of commission and omission to conceal transgressions. Descriptions of four scenarios varied in terms of whether the protagonists lied to benefit themselves or others and whether the transgression was deliberate or accidental. The results showed that both age groups of children, as well as adults, judged that lies of commission were morally worse than lies of omission in all four scenarios, indicating that omission bias clearly occurs in moral judgments of lies. However, there were age differences in the magnitude of omission bias. Third and sixth graders generally showed omission bias of the same magnitude for all scenarios, whereas omission bias in adults was stronger for the scenarios that benefited self rather than others and for scenarios in which deliberate transgressions, rather than accidental ones, were concealed. These results reveal differences in moral judgments of lies between middle childhood and adulthood.

Exploring Clinical Practice and Developing Clinician Self-Reflection Through Cross Self-Confrontation Methodology: An Application Within an Addiction Medicine Unit

Use of the methodology of cross self-confrontation (CSC) is limited in the field of healthcare and in the context of clinical practice. We applied this methodology within an addiction medicine unit of a university hospital, as part of an exploration of addiction-related clinical difficulties. Cross self-confrontation was used according to a 3-phase design based on video recorded clinical interviews with pairs of nurses and medical doctors. The article reports and discusses the application of CSC in a specific clinical context and illustrates the methodological process through one result. Findings suggest two major strengths of CSC in the context of clinical practice research and education: (1) the capacity to elicit tacit knowledge from daily clinical practice and (2) the ability to enhance self-reflection by questioning professionals both individually and collectively. Further use of CSC in nursing surroundings and clinical settings should be encouraged.

Impaired Perception of Unintentional Transgression of Social Norms after Prefrontal Cortex Damage: Relationship to Decision Making, Emotion Recognition, and Executive Functions

OBJECTIVE

Patients with prefrontal cortex damage often transgress social rules and show lower accuracy in identifying and explaining inappropriate social behavior. The objective of this study was to examine the relationship between the ability to perceive other unintentional transgressions of social norms and both decision making and emotion recognition as these abilities are critical for appropriate social behavior.

METHOD

We examined a group of patients with focal prefrontal cortex damage (N = 28) and a group of matched control participants (N = 28) for their abilities to detect unintentional transgression of social norms using the "Faux-Pas" task of theory of mind, to make advantageous decisions on the Iowa gambling task, and to recognize basic emotions on the Ekman facial affect test.

RESULTS

The group of patients with frontal lobe damage was impaired in all of these tasks compared with control participants. Moreover, all the "Faux-Pas", Iowa gambling, and emotion recognition tasks were significantly associated and predicted by executive measures of inhibition, flexibility, or planning. However, only measures from the Iowa gambling task were associated and predicted performance on the "Faux-Pas" task. These tasks were not associated with performance in recognition of basic emotions. These findings suggest that theory of mind, executive functions, and decision-making abilities act in an interdependent way for appropriate social behavior. However, theory of mind and emotion recognition seem to have distinct but additive effects upon social behavior. Results from VLSM analysis also corroborate these data by showing a partially overlapped prefrontal circuitry underlying these cognitive domains.

Spacious Environments Make Us Tolerant-The Role of Emotion and Metaphor

The physical environment plays an important role in moral cognition. Previous research has demonstrated that the physical environment affects individual moral judgment. Investigators have argued that the environment influences moral judgment through emotion and cognition, such as during metaphor processing. Following the intensification of urbanization and increases in population size, the phenomenon of a narrow environment has become more common. However, the relation between environmental spaciousness and moral judgment has not been thoroughly examined. We examined the effect of environmental spaciousness (spaciousness vs. narrowness) on moral judgments in Experiment 1 and Experiment 2. Results showed that participants report a higher rating score of moral judgment in more spacious environments compared with narrow environments. We further explored the roles of emotion and metaphor in the relation between environmental spaciousness and moral judgments. We found support for a partial mediation effect of emotion in the relationship between environmental spaciousness and moral judgment. The results also supported an association between the concept of spaciousness and tolerant cognition. Spacious environments may elicit positive emotions and more tolerant cognition, which in turn influences moral judgment. These results provide new evidence for the influence of the environment on moral judgments, and more attention may be warranted to incorporate this relationship in environmental design.

Moral metaphorical effect of cleanliness on immoral workplace behaviors

Cleanliness connotes cleanness, hygiene, and beauty. Physical cleanliness is also a metaphor for moral purity, as proposed in recent literature. However, cleanliness means not only physical cleanliness but also environmental cleanliness. The article proposes that environmental cleanliness and physical self-cleanliness may metaphorically influence immoral behaviors in the workplace, and their effects may be different. The current study conducted a 2 (environmental cleanliness: clean vs. dirty) × 3 (self-cleanliness: hands-cleansing vs. face-cleansing vs. non-cleansing) between-subjects field experiment with employees as participants in a Chinese enterprise. One-hundred-seventy-seven employees volunteered to participate in the experiment. It was found that a clean workplace, rather than physical self-cleansing, renders harsh moral judgment regarding immoral workplace behaviors. The participants were less willing to accept immoral workplace behaviors in a clean environment than in a dirty environment, while self-cleanliness (hands-cleansing or face-cleansing vs. non-cleansing) had no significant influence on employees’ moral judgments of immoral workplace behaviors. In addition, the significant effects of environmental cleanliness were found in all the ten dimensions of immoral workplace behaviors. The findings reveal the metaphorical association between environmental cleanliness and the concept of higher social moral norms, and confirm that environmental cleanliness is a key factor leading to moral metaphorical effects. This result provides unique insight to the social significance of environmental cleanliness, and has important implications to prevent immoral workplace behaviors. A theoretical framework is proposed to explain why environmental cleanliness is more likely to affect moral judgment involving organizational interests than self-cleanliness. Considering most previous research has been done with samples of college students, this study is especially valuable through a field experiment on actual employees.

The scent of attraction and the smell of success: crossmodal influences on person perception

In recent decades, there has been an explosion of research into the crossmodal influence of olfactory cues on multisensory person perception. Numerous peer-reviewed studies have documented that a variety of olfactory stimuli, from ambient malodours through to fine fragrances, and even a range of chemosensory body odours can influence everything from a perceiver's judgments of another person's attractiveness, age, affect, health/disease status, and even elements of their personality. The crossmodal and multisensory contributions to such effects are reviewed and the limitations/peculiarities of the research that have been published to date are highlighted. At the same time, however, it is important to note that the presence of scent (and/or the absence of malodour) can also influence people's (i.e., a perceiver's) self-confidence which may, in turn, affect how attractive they appear to others. Several potential cognitive mechanisms have been put forward to try and explain such crossmodal/multisensory influences, and some of the neural substrates underpinning these effects have now been characterized. At the end of this narrative review, a number of the potential (and actual) applications for, and implications of, such crossmodal/multisensory phenomena involving olfaction are outlined briefly.

Deontological and Altruistic Guilt Feelings: A Dualistic Thesis

In this paper we argue in favor of the existence of two different guilt feelings: altruistic guilt (AG) and deontological guilt (DG). AG arises from having harmed, through one's own action or omission, an innocent victim, while DG arises from the transgression of an internalized norm. In most daily experiences of guilt feelings both types are present, but we argue that they are not traceable to each other and that each can be present without the other. We show that the two guilt feelings can be distinguished with reference to behavioral, cognitive, and neurophysiological aspects. Moreover, we demonstrate that they are differently related to other processes and emotions. AG is connected with pain, empathy and ToM. DG is strongly related to disgust. We briefly illustrate some implications for moral psychology and clinical psychology.

The experience of disgust by nursing and midwifery students: An interpretative phenomenological approach study

Although disgust is recognized as a common and prominent emotion in healthcare, little is known about how healthcare professionals understand, experience and conceptualize disgust. The aim of the study was to gain an in-depth understanding of how nursing and midwifery students experience, understand and cope with disgust in their clinical work. Interviews were transcribed verbatim and analysed using interpretative phenomenological analysis (IPA). Six participants (all women: two nursing students, four midwifery students) from a university in the South of England were interviewed. Four superordinate themes with eight subthemes were identified. Overall, findings suggest that participants experience both moral and physical disgust; however, they find it difficult to talk about and use other terms to describe their experience. Findings are discussed through the lens of social identity theory, to understand the relevance of professional identity and how this might further maintain the disgust taboo. The strategies participants have developed in order to cope with disgust are explored and understood within the current healthcare climate. Future research should focus on ways of addressing the experience of disgust by healthcare professionals in order to improve the quality of care provided, especially in the climate of the COVID-19 crisis.

Environmental Aesthetic Value Influences the Intention for Moral Behavior: Changes in Behavioral Moral Judgment

The environment affects moral behavior. Previous research found that a beautiful environment leads to pro-social behavior, which is related to behavioral intention. However, the effect of environmental aesthetic value on immoral and moral behavior remains unclear. Therefore, in the present study, we explored the effect of environmental aesthetic value on behavioral intention and its possible mechanisms. We conducted four experiments. Experiment 1 adopted the priming paradigm and IAT paradigm to explore the relationship between environmental aesthetic value and behavioral intention. It used photographs of the environment as priming stimuli and scene drawings of behavior as target stimuli. The results showed that participants had a higher intention to engage in moral behavior in an environment with a high aesthetic value, and a lower intention to engage in immoral behavior, compared to in an environment with a low aesthetic value. Similarly, an environment with a low aesthetic value was related to immoral behavior. Experiment 2 further explored the possible mechanism for the above results: changes in moral judgment. The results showed that moral judgment in different environments may lead to different behavioral intentions. The current study extends prior research by demonstrating the effect of environmental aesthetic value on behavioral intention and moral judgment, and good knowledge about the relationship between environmental aesthetic value and moral behavior. In addition, it provides a new hypothesis for the relationship between environment and behavior according to the results of the environment-behavior matching hypothesis, which can provide a new perspective on moral education.
