“Taken, Blessed, Broken, Given”: Lukan Table Practices in the Faith Formation of Christian Communities

Luke’s Eucharistic pattern not only serves as a Christological marker, but formative pattern for Christian faith communities. In this article, I appeal to Luke’s Eucharistic pattern to advance the claim that hospitable Eucharistic table practices are not only consistent with Luke’s Christology but also form faith that is capable of confronting and dismantling psychological disgust responses to outsiders. This motif is expanded in Luke–Acts, where acts of table fellowship become the places where socio-moral barriers are transgressed, signaling the good news of the gospel, especially for Gentiles. Drawing from biblical scholarship as well as recent work in psychology, I will advance the claim that hospitable Eucharistic practices not only expose disgust psychology in the faith formation of persons but also act as a potential balm, forming persons according to the good news proclaimed in Luke–Acts.

Virtual Reality Exposure Therapy for Treating Fear of Contamination Disorders: A Systematic Review of Healthy and Clinical Populations.

Virtual Reality Exposure Therapy (VRET), particularly immersive Virtual Reality Exposure Therapy (iVRET), has gained attraction as an innovative approach in exposure therapy (ET), notably for some anxiety disorders with a fear of contamination component, such as spider phobia (SP) and obsessive-compulsive disorder (OCD). This systematic work investigates iVRET's effectiveness in modulating disgust emotion-a shared aberrant feature across these disorders. Recent reviews have evaluated VRET's efficacy against in vivo ET. However, emerging evidence also highlights iVRET's potential in diminishing atypical disgust and related avoidance behaviors, expanding beyond traditional fear-focused outcomes. Our systematic synthesis, adhering to PRISMA guidelines, aims to fill this gap by assessing iVRET's efficacy in regulating disgust emotion within both clinical and at-risk populations, identified through standardized questionnaires and subjective disgust ratings. This research analyzes data from eight studies on clinical populations and five on healthy populations, offering an insight into iVRET's potential to mitigate the aberrant disgust response, a common transdiagnostic feature in varied psychopathologies. The findings support iVRET's clinical relevance in disgust management, providing evidence for a broader therapeutic application of iVRET and pointing out the need for more focused and complete investigations in this emergent field.

Contamination-Focussed Vignettes as an Analogue of Infectious Pandemics: An Experimental Validation using the State Disgust and Anxiety Responses in OCD.

Despite infectious pandemics proving particularly detrimental to those with Obsessive-Compulsive Disorder (OCD), the investigation of analogous experimental paradigms is lacking. To address this gap, we conducted two studies employing vignettes that depicted contamination-related situations commonly experienced during a pandemic (e.g., Coughing into hands and failing to use hand sanitizer). We manipulated the salience of these vignettes across three levels: high contamination, low contamination, and a neutral control condition. Our examination of state anxiety and disgust responses in all participants revealed the successful manipulation of the vignettes' impact. Specifically, individuals with more severe OCD symptoms reported significantly higher levels of state disgust and anxiety for both high and low contamination vignettes, in contrast to the group with lower symptom severity. No significant differences were observed in the neutral vignette condition between the high- and low-scoring groups. Interestingly, for those with higher OCD symptoms, high salience contamination-focused vignettes resulted in similarly elevated state disgust and anxiety, regardless of whether the vignettes were situated in public (Study 1) or domestic (Study 2) settings. This suggests that the heightened sensitivity to contamination-related scenarios observed in individuals with OCD symptoms in the present study is not confined to a specific context. These findings support the use of contamination-focused vignettes as analogues for studying infectious pandemics and provide valuable insights into OCD models, interventions, and future research.

Disgust responses to virtual erotica: Analysis of their interaction with sexual anxiety and immersive tendencies

Previous research suggests that experiencing disgust in sexual contexts may negatively impact sexual satisfaction and functioning. However, little is known about the mechanisms (e.g., sexual anxiety) that influence or underlie sex-related disgust. Additionally, immersive tendencies may play a role in shaping emotional experiences when presented with sexual cues. Recent technological advancements, especially in virtual reality (VR), offer a promising avenue to explore emotions in simulated intimate and sexual interactions. This study aimed to examine the influence of sexual anxiety and immersive tendencies on reported levels of disgust when exposed to virtual erotica. A sample of 59 participants (≥ 18 years) completed self-report questionnaires of sexual anxiety and immersive tendencies. Levels of disgust were assessed during exposure to synthetic virtual characters engaging in erotic behaviours of increasing intensity across six scenarios, ranging from flirting to nudity, masturbation, and orgasm. Linear mixed models were performed on observed data. Higher levels of sexual anxiety were significantly associated with increased disgust throughout the immersive experience (β = 0.48), while greater immersive tendencies were significantly linked to lower disgust ratings (β = −0.66). Additionally, disgust ratings significantly increased with the intensity of the virtual sexual stimuli (β = 0.48). Virtual erotica shows promise as a tool to investigate sex-related disgust and its related mechanisms, such as sexual anxiety and immersive tendencies.

Age-related disgust responses to signs of disease

ABSTRACT Previous studies found similarities in adults’ disgust responses to benign (e.g. obesity) and actual disease signs (e.g. influenza). However, limited research has compared visual (i.e. benign and actual) to cognitive (i.e. disease label) disease cues in different age groups. The current study investigated disgust responses across middle childhood (7–9 years), late childhood (10–12 years), adolescence (13–17 years), and adulthood (18+ years). Participants viewed individuals representing a benign visual disease (obese), sick-looking (staphylococcus), sick-label (cold/flu), and healthy condition. Disgust-related outcomes were: (1) avoidance, or contact level with apparel the individual was said to have worn, (2) disgust facial reactions, and (3) a combination of (1) and (2). Avoidance was greater for the sick-looking and sick-label than the healthy and obese conditions. For facial reaction and combination outcomes, middle childhood participants responded with greater disgust to the sick-looking than the healthy condition, while late childhood participants expressed stronger disgust towards the sick-looking and obese conditions than the healthy condition. Adolescents and adults exhibited stronger disgust towards sick-label and sick-looking than obese and healthy conditions. Results suggest visual cues are central to children’s disgust responses whereas adolescents and adult responses considered cognitive cues.

Facial disgust in response to touches, smells, and tastes.

Disgust serves to defend the body from the entry of toxins and disease. Central to this function is a strong relationship with the proximate senses of smell, taste, and touch. Theory suggests that distinct and reflexive facial movements should be evoked by gustatory and olfactory disgusts, serving to impede bodily entry. While this hypothesis has received some support from facial recognition studies, whether smell and taste disgusts actually produce distinct facial responses, is unknown. Moreover, there has been no assessment of the facial response evoked by contact with disgusting objects. To address these issues, this study compared facial responses to touch, smell, and taste disgusts. Sixty-four participants were asked to touch, smell, and taste disgust-evoking and neutral control stimuli, and rate them on disgust, on two occasions-first, while they were video recorded and second, with facial electromyography (EMG) applied (measuring levator labii and corrugator supercilii activity). Videos were coded for facial expressions by humans and for facial action units (FAUs) by machines. Self-report data confirmed the disgust stimuli as highly disgusting. Comparison of the overall pattern of FAUs evoked by touch, smell, and taste disgusts, indicated two distinct facial disgusts for the proximate senses-a chemosensory and a tactile-disgust face. The nose wrinkle and upper lip raise were central to all facial disgusts, indicating their centrality to the disgust face. Several facial disgusts appear to exist, each with different functional goals. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Age differences in emotional reactions to ageist memes and changes in age of one's Best Self

Memes on social media can carry ageist messages and can elicit reactions that are both emotional and self-evaluative. The present study investigates age-related differences in nine discrete emotions and in the evaluation of when individuals have been or will be their best selves. Participants (n = 360) representing young (m = 26 years), middle-aged (m = 39 years) and older adults (m = 63 years) were randomly assigned to view either non-ageist (animals) or ageist (e.g., incompetent older people) memes. After viewing memes, we assessed nine emotional reactions (i.e., fear, anger, sadness, happiness, anxiety, discomfort, disgust, surprise, enjoyment) and Best Self evaluations. Younger and middle-aged people reported more intense emotional reactions to memes than older people, with the exception that older people reported more discomfort and disgust in response to ageist versus non-ageist memes. Younger adults were less surprised by ageist memes (vs. non-ageist) and for all age groups ageist memes (vs. non-ageist) elicited less happiness and enjoyment and were less likely to be shared. With respect to evaluations of one's Best Self, older individuals were more likely to report being their best selves in the past, while after viewing ageist memes, younger individuals were more likely to report being their best selves in the future. Emotions of disgust and discomfort were related to identifying one's Best Self as further in the past. The current study adds to the literature on the impact of ageism by examining age-related differences in the emotions and self-evaluations experienced when confronted with memes on social media.

AI-ASSISTED emotion analysis during complementary feeding in infants aged 6–11 months

This study aims to explore AI-assisted emotion assessment in infants aged 6–11 months during complementary feeding using OpenFace to analyze the Actions Units (AUs) within the Facial Action Coding system. When infants (n = 98) were exposed to a diverse range of food groups; meat, cow-milk, vegetable, grain, and dessert products, favorite, and disliked food, then video recordings were analyzed for emotional responses to these food groups, including surprise, sadness, happiness, fear, anger, and disgust. Time-averaged filtering was performed for the intensity of AUs. Facial expression to different food groups were compared with neutral states by Wilcoxon Singed test. The majority of the food groups did not significantly differ from the neutral emotional state. Infants exhibited high disgust responses to meat and anger reactions to yogurt compared to neutral. Emotional responses also varied between breastfed and non-breastfed infants. Breastfed infants showed heightened negative emotions, including fear, anger, and disgust, when exposed to certain food groups while non-breastfed infants displayed lower surprise and sadness reactions to their favorite foods and desserts. Further longitudinal research is needed to gain a comprehensive understanding of infants' emotional experiences and their associations with feeding behaviors and food acceptance.

Accusing the opponent of divinity violations in intergroup conflicts: Bystander reactions to harmfulness and underdog status as a function of the autonomy–divinity discrepancy

We experimentally investigated psychological responses of bystanders to violations of moral codes to find out why divinity violations may be more effective for gaining victimhood status than autonomy violations in real-world intergroup conflicts. In particular, we considered how anger versus disgust responses are differentially invoked by violations of autonomy versus divinity ethics. Two experiments compared autonomy versus divinity violations in interaction with two other parameters known to produce different effects: level of harm (Experiment 1) and differential intergroup power (Experiment 2). Overall, we found support for the proposed dissociation in anger versus disgust responses to autonomy versus divinity violations in a way that the anger responses to autonomy violations were amplified but disgust responses to divinity violations were not affected when the moral violation was more harmful and the perpetrator was more powerful than the victim. We discuss the implications of the cognitive processes involved in considering autonomy versus divinity violations, and the functionality for parties to intergroup conflict of accusing the opponent of divinity violations.

Conscious knowledge of CS-UCS contingency information affects extinction retrieval of conditioned disgust responses: Findings from an online de novo disgust conditioning task.

The present study aimed to establish and develop an online de novo conditioning paradigm for the measurement of conditioned disgust responses. We further explored the effects of explicit instructions about the CS-UCS contingency on extinction learning and retrieval of conditioned disgust responses. The study included a sample of 115 healthy participants. Geometric figures served as conditioned stimuli (CS) and disgust-evoking pictures as unconditioned stimuli (UCS). During disgust conditioning, the CS+ was paired with the UCS (66% reinforcement) and the CS- remained unpaired; during extinction and retrieval, no UCS was presented. Half of the participants (n=54) received instructions prior to the disgust extinction stating that the UCS will not be presented anymore. 1-2 days or 7-8 days later participants performed a retrieval test. CS-UCS contingency, disgust and valence ratings were used as dependent measures. Successful acquisition of conditioned disgust response was observed on the level of CS-UCS contingency, disgust and valence ratings. While some decline in valence and disgust ratings during the extinction stage was observed, contingency instructions did not significantly affect extinction performance. Retrieval one week later revealed that contingency instructions increased the discrimination of the CSs. Extinction of conditioned disgust responses is not affected by explicit knowledge of the CS-UCS contingencies. However, contingency instructions prior to extinction seem to have a detrimental effect on long-term extinction retrieval.

The Role of Childhood Experiences in the Development of Disgust Sensitivity: A Preliminary Study on Early Moral Memories.

Disgust is a basic emotion evolved to safeguard our omnivorous species from contagion. Although the factors eliciting disgust typically involve concerns related to physical contamination, physical disgust responses are also prompted by moral transgressions, (i.e. cannibalism, pedophilia, betrayal). The link between the general propensity to experience disgust (i.e. "Disgust Sensitivity") and morality, in particular in the deontological domain, is supported by an increasing amount of data on clinical and non-clinical sample. Evolutionistic explanations of this link posit that disgust evolved to indicate the presence of a threat to the integrity of the individual not only in the physical domain but also in the social and moral domain.In addition to the evolutionary point of view, this link could also be better investigated in terms of individual development. To the best of our knowledge, literature is scarce regarding which early experiences are associated to high DS. Therefore, this study aims to explore the content of early memories associated with disgust. Based on the strict link between disgust and morality, we hypothesized an association between DS and early memories of moral criticism. 60 non-clinical participants filled in measures of DS. They were then presented with an auditory disgust induction, after which they recalled early memories through the technique of the "affect bridge". 10 independent raters assessed the emotional content of the memories on visual-analogical scales. Results showed a positive association between disgust sensitivity and the propensity to experience deontological guilt. There was also a significant positive association between disgust sensitivity and moral memories, in particular relating to early experiences of being the object of contempt, moral criticism, anger, and of being held responsible. These data directly support the centrality of early morally-loaded interpersonal experiences in the development of DS, confirming the link between disgust and morality also at the level of individual historical development.

Food as a key disgust elicitor in infancy and childhood: Previous research and opportunities for future study.

Disliked foods may have important value in the study of the development of disgust. The current review draws from literature across disciplines, including theories of disgust and studies of the development of eating behavior and food preferences, to highlight food as an important category of disgust responses across a wide age range, including children as young as 3 years old and adults. Children's disgust responses to certain types of food are considered to be both innate and culturally constrained behaviors, and their perceptions of other people's food choices indicate potential links between foods and cultural groups. We end by discussing several ongoing and future research areas, including connections between disgust responses and food rejection in infancy and children's food rejection behaviors across cultures.

Ewww-Investigating the neural basis of disgust in response to naturalistic and pictorial nauseating stimuli.

Emotion induction in psychological and neuroscientific research has been mostly done by presenting participants with picture or film material. However, it is debatable whether this passive approach to emotion induction results in an affective state comparable to real-life emotions, and if the neural correlates of emotion processing are ecologically valid. To investigate the appropriateness of pictures for the induction of emotions, we presented 56 participants in a within-subjects design with naturalistic disgusting and neutral stimuli as well as with pictures of said stimulus material while recording continuous EEG data. We calculated asymmetry indices (AIs) for alpha power as an index of emotion processing and emotion regulation at the F3/4, F5/6, F7/8, and O1/2 electrode pairs. Participants reported higher disgust ratings for disgusting naturalistic compared to disgusting pictorial stimuli. Investigating changes in the EEG signal in participants with a pronounced disgust response (n = 38), we found smaller AIs for naturalistic stimuli compared to pictures. Moreover, in this disgusted sub-sample, there were smaller AIs in response to naturalistic disgusting stimuli compared to pictorial disgusting and neutral stimuli at the O1/2 electrode pair indicating stronger activation of the right relative to the left hemisphere by naturalistic stimuli. As the right hemisphere has been shown to display dominance in processing negative and withdrawal-associated emotions, this might indicate that naturalistic stimuli are more appropriate for the induction of emotions than picture stimuli. To improve the validity of results from emotion induction, future research should incorporate stimulus material that is as naturalistic as possible.

Attenuating experimentally acquired disgust: Comparing counterconditioning, exposure and unconditioned stimulus revaluation

Background and objectivesDisgust is implicated in the aetiology and maintenance of various psychopathologies such as anxiety disorders and obsessive-compulsive disorders. Despite its prominent role in psychopathology, little is known about how to effectively attenuate disgust. The study examined strategies to modify an experimentally acquired disgust response in a sample of undergraduate students. MethodsA conditioning paradigm was used where participants (N = 175) first underwent acquisition of disgust via repeated presentations of a neutral picture (functioning as conditioned stimulus + [CS+]) paired with a disgusting picture (functioning as unconditioned stimulus [US]). Participants were then randomly assigned to either an exposure (repeated presentation of CS-only trials), counterconditioning (pairing CS+ with pleasant pictures), US revaluation (pairing disgusting US with pleasant pictures) or a control (filler task) condition. We hypothesised that counterconditioning would attenuate evaluative learned disgust to the greatest extent, relative to exposure and US revaluation. Participants’ evaluations of the pictures were attained with a disgust-pleasantness visual analogue scale. ResultsExposure, counterconditioning and US revaluation reduced disgusting US expectancies. However, experimental and control conditions did not differ in terms of attenuating disgust towards CS+. LimitationsMeasures of psychopathology and implicit evaluations of disgust were not collected. Modest power might have limited significance of the results. ConclusionsNo statistical support for the effectiveness of disgust attenuation following exposure nor counterconditioning were found. Findings for US revaluation are inconclusive. Implications for future research are discussed.

Horror Manga: An Evolutionary Literary Perspective

Abstract This article provides support for the argument that horror media “works” by activating evolved cognitive and affective systems that are flexibly tailored to local socio-ecological contexts. Guided by previous work using evolutionary theory to study horror literature (e.g., Clasen 2012, 2018, 2019), I investigate horror manga’s popularity and international market, which indicate a cross-cultural preoccupation with horror transmedia that is expli­cable in terms of the form’s ability to target evolved psychological systems. Specifically, these multimodal texts elicit the evolved emotions of anxiety, fear, and disgust in response to culturally specific and evolutionarily relevant narratives, characters, antagonists, and environments. Thus, horror manga reflects the myths, folklore, and religious traditions of Japanese society in addition to salient ubiquitous evolutionary threats such as predators, antisocial conspecifics, and infectious diseases.

A Theoretical Proposal for a Perceptually Driven, Food-Based Disgust that Can Influence Food Acceptance During Early Childhood

Disgust, the “revulsion at the prospect of (oral) incorporation of an offensive substance”, is not thought to influence the acceptability of food during infancy and early childhood. This is because the feelings of disgust require a person to have developed an understanding of contagion and to be aware of the nature and origin of a given disgust stimulus, which does not occur until around seven years of age. Despite this need for higher cognitive functioning, studies have demonstrated the potential for disgust in children as young as two years of age. Furthermore, it seems that young children can demonstrate aspects of disgust without having the cognitive understanding of contagion. This review is the first paper to demonstrate how core disgust may influence the acceptability of foods from late infancy. Firstly, food neophobia may act as a catalyst for disgust. Secondly, that disgust in young children can result from the visual perceptual features of food (as opposed to a cognitive response based on non-food disgust stimuli). Thirdly, that some disliked foods have contaminating properties, much like non-food, adult disgust stimuli (e.g. insects). Fourthly, that the response reduces as the child ages and learns more about food and its variability between presentations. Finally, individual differences exist to explain why an individual child may be more or less likely to respond to a given food with a disgust response. This proposal adds to the current debate relating to the motivations of ‘picky’ eating during early childhood and introduces an alternative to the proposal that these behaviours are the result of a child’s desire for autonomy.

Sexual-specific disgust sensitivity mechanisms in homonegativity and transnegativity; the mediating role of right-wing authoritarianism (RWA)

ABSTRACT Disgust specific to sexual stimuli has been thought to be an adaptation that serves purposes of pathogen-avoidance, partner selection and social dominance. While the link between disgust responses and homonegative and transnegative attitudes has been relatively established, it is not yet clear why. Literature using evolutionary psychology perspectives of these phenomena is scarce in areas with substantial LGBT-related violence like Colombia. This research aimed to study the interplay of predispositional (e.g. sociodemographic, reported contact), affective (e.g. disgust sensitivity) and cognitive (e.g. Right-Wing Authoritarian) variables in homonegative and transnegative attitudes of Colombian adults. Participants (N = 272) had a mean age of 26.38 (SD = 9.47), women comprised 72% of the sample and men 28%. Hierarchical regression analyses showed that increased sexual specific disgust sensitivity and greater RWA predicted stronger homonegativity and transnegativity. The relationship between sexual disgust and prejudice was partially mediated by RWA. Findings suggest that sexual disgust sensitivity adaptations in homonegativity and transnegativity may respond to selection pressures that differ from pathogen-avoidance perspectives, and that are associated with maintaining social hierarchy and social dominance. Anti-prejudice initiatives would benefit from targeting emotional responses of sexual disgust, especially within communities and institutions that have historically endorsed conservative and traditional values.

When Politics Disgust: Emotional versus Rational Processing of Attack Ads

ABSTRACT Following the 2016 Presidential election, 82% of respondents felt disgusted with politics. This revulsion persisted into the 2020 Presidential campaign with voters reporting avoidance of voting and increased disgust with the opposition. Previous political research has noted a moderate negative correlation between negative political campaigning and trust in government and mixed findings on voting intentions. We make a distinction between emotional versus rational processing of political attack ads and use that distinction to demonstrate that emotional processing of these ads evokes disgust and accordingly avoidance of voting and decreased trust in government. Moreover, disgust evoked by political attack advertisements is transferred to politics in general, dampening voting intentions, trust in government, and in the short term political aspirations. This research helps explain previous mixed findings in the negative political campaigning literature and suggests how emotional processing and the disgust response are alienating portions of the electorate.

Auditory affective processing, musicality, and the development of misophonic reactions.

Misophonia can be characterized both as a condition and as a negative affective experience. Misophonia is described as feeling irritation or disgust in response to hearing certain sounds, such as eating, drinking, gulping, and breathing. Although the earliest misophonic experiences are often described as occurring during childhood, relatively little is known about the developmental pathways that lead to individual variation in these experiences. This literature review discusses evidence of misophonic reactions during childhood and explores the possibility that early heightened sensitivities to both positive and negative sounds, such as to music, might indicate a vulnerability for misophonia and misophonic reactions. We will review when misophonia may develop, how it is distinguished from other auditory conditions (e.g., hyperacusis, phonophobia, or tinnitus), and how it relates to developmental disorders (e.g., autism spectrum disorder or Williams syndrome). Finally, we explore the possibility that children with heightened musicality could be more likely to experience misophonic reactions and develop misophonia.
