Abstract
Consumers' emotional responses complement sensory and hedonic ratings in the prediction of food choice and consumption behaviour. The challenge with the measurement of consumption emotions is that emotions are highly context dependent. For emotion evaluations to bring greater insight to food research and development, it is essential that the influence of contextual variables on emotion are quantified. The present study contributes to the discussion with an investigation of the effect of an unfamiliar social presence on affective facial responses to visual food stimuli. Seventy participants (52 female and 18 male) viewed food images of varying acceptability either alone, or in the presence of the researcher. Subjective liking ratings were measured using a labelled affective magnitude scale, and facial muscle activity from zygomaticus major (contracted during smiling), corrugator supercilii (contracted during frowning) and levator labii superioris (contracted during nose wrinkling) were measured with an EMG recording system. Controlling for individual differences in facial expressivity and food image acceptability using linear mixed models, it was found that social context did not predict smiling or frowning muscle activity. Social context did predict the intensity of muscle activity indicative of a disgust response, with participants in the observed condition exhibiting less levator activity than participants in the alone condition. Regardless of social context, each muscle was found to have a relationship with subjective liking, with the direction of effects as expected. The results indicate that emotional stimuli and social context both influence food-evoked facial expression and provides support for the utility of facial EMG in measuring food-evoked emotion.

Abstract
BACKGROUND Emotional processes and responses are underestimated in stroke patients because the massive clinical picture of large hemispheric strokes often hides these symptoms. We report on a patient with peculiar unpleasant emotional responses after temporal stroke. CASE PRESENTATION We describe a 62-years old man with significant unpleasant emotional responses that occurred after an acute episode of confusional state, disorientation, agitation, vertigo, postural instability, vomiting, and photophobia. Since then, he complained that vision of pictures containing curved/multicolored lines or tangles was associated with an uncomfortable feeling of fear and disgust, lasting few minutes, so that he avoided looking at them. Notably, he also showed an abnormal facial expression of disgust and fear, together with neurovegetative reaction and horripilation, at the presentation of pictures of objects or animals containing curved, multicolored, or tangled lines. A post-acute infarction of the right temporal-insular region, together with mild periventricular white matter changes, were evident at the brain magnetic resonance imaging. CONCLUSIONS The anterior insula is crucial in transforming unpleasant sensory input into visceromotor reactions and the accompanying feeling of disgust. It is also known that temporal pole modulates visceral emotional functions in response to emotionally evocative perceptual stimuli. In the present case, the ischemic lesion of anterior part of the insula and temporal pole may have caused a decoupling of emotional and visceral response to complex visual stimuli. Further reports will provide a significant contribution to the taxonomy of these complex and relatively uncommon non-motor post-stroke symptoms that negatively affect quality of life.

Abstract
Intimate partner violence (IPV) is a persistent problem in our society, and there is strong evidence for the existence of bidirectional violence in heterosexual romantic relationships. Couples' research has long focused on conflict and distressed communication patterns as a source of relationship distress and eventual dissolution. In addition to relationship dissatisfaction, dysfunctional communication also appears to be associated with elevated risk of IPV. In fact, one study found that communication difficulties were one of the most frequently self-reported motivations for committing partner violence in a sample of both males and females arrested for IPV. The current study sought to explore the association between the expression of distressed communication (contempt and anger) during a laboratory conflict discussion and reports of IPV perpetration using a dyadic data analysis method, the Actor Partner Interdependence Model, in a large ethnically diverse sample of heterosexual couples. We found that negative communication in the form of contempt was not only associated with one's own physical assault perpetration, but it was also associated with physical assault perpetration of the other partner. In contrast, anger was only associated with one's own physical assault perpetration. Therefore, our results highlight the potential efficacy of treatments for IPV that target negative communication patterns and affect.

Abstract
Individuals vary in their personal space (PS) size as reflected by the preferred distance to another person during social interactions. A previous study with adults showed that pathogen-relevant disgust proneness (DP) predicted PS magnitude. The present study investigated whether this association between DP and PS already exists in 8- to 12-year-old children (144 girls, 101 boys). The children answered a disgust questionnaire with the two trait dimensions "core disgust (contact with spoiled food and poor hygiene) and "death-relevant disgust" (imagined contact with dead and dying organisms). PS magnitude was assessed with a paper-pencil measure (drawing a PS bubble; Experiment 1) or with the stop-distance task (preferred distance to an approaching woman or man; Experiment 2). In both experiments, only death-related disgust predicted PS magnitude and only if the approaching person was male. The current study questions the relevance of pathogen-related disgust in children for regulating interpersonal distance.

Abstract
Pathogen threat affects social preferences and responses across species. Here we examined the effects of social context and the infection status of conspecific females and males on the social and mate responses of female mice. The responses of female mice to males were rapidly affected by the presence of infected female conspecifics and infected males. In mice odor cues drive appetitive and aversive social and mate responses. Brief (1 min) exposure to the fresh urinary odors of females infected with the murine nematode parasite, Heligmosomoides polygyrus, attenuated the responses of other uninfected females to the odors of naturally preferred unfamiliar males and enhanced their preferences for familiar males. Likewise exposure to the odors of a male either infected with H. polygyrus or treated with the bacterial endotoxin, lipopolysaccharide, reduced the responses of females to the odors of unfamiliar males. In addition, females displayed an avoidance of, and discrimination against, male mice whose odors had been associated with that of an infected female ("guilt by association") and a preference for the odors associated with an uninfected female ("mate copying"). These shifts in preferences for female associated male odors were attenuated in a dose-related manner by pre-treatment with the oxytocin receptor antagonist, L-368,899. These findings show that social information associated with the infection status of conspecifics can rapidly bias the mate preferences of female mice in an oxytocin receptor dependent manner.

Abstract
New food technologies have a high potential to transform the current resource-consuming food system to a more efficient and sustainable one, but public acceptance of new food technologies is rather low. Such an avoidance might be maintained by a deeply preserved risk avoidance system called disgust. In an online survey, participants (N = 313) received information about a variety of new food technology applications (i.e., genetically modified meat/fish, edible nanotechnology coating film, nanotechnology food box, artificial meat/milk, and a synthetic food additive). Every new food technology application was rated according to the respondent's willingness to eat (WTE) it (i.e., acceptance), risk, benefit, and disgust perceptions. Furthermore, food disgust sensitivity was measured using the Food Disgust Scale. Overall, the WTE both gene-technology applications and meat coated with an edible nanotechnology film were low and disgust responses toward all three applications were high. In full mediation models, food disgust sensitivity predicted the disgust response toward each new food technology application, which in turn influenced WTE them. Effects of disgust responses on the WTE a synthetic food additive were highest for and lowest for the edible nanotechnology coating film compared to the other technologies. Results indicate that direct disgust responses influence acceptance and risk and benefit perceptions of new food technologies. Beyond the discussion of this study, implications for future research and strategies to increase acceptance of new food technologies are discussed.

Abstract
To investigate the emotional conflict processing during the processing of emotional stimuli in individuals with different levels of social adjustment through developing an event-related potential (ERP) method, the study used positive words (happy), negative words (disgusted), positive faces and negative faces as experimental materials for a face-word Stroop emotional conflict task, which was completed by 34 participants. For the N2 component, there was a significant difference between the high and low social adjustment groups for the congruent condition; the low social adjustment group evoked more negative amplitude under the congruent condition. Under the incongruent condition, there was a marginally significant difference between the high and low social adjustment groups; the low social adjustment group evoked more negative amplitude under the incongruent condition. For the SP component, there were no significant differences for both the high and low social adjustment group between the congruent and incongruent conditions of emotional conflict. However, within the low social adjustment group, the incongruent evoked more positive amplitude. Our findings indicate that the difference in the emotional conflict process between individuals with high and low social adjustment mainly lies in the early processing stages of emotional information. That is, for both congruent and incongruent emotional stimuli, individuals with high social adjustment showed better emotional conflict monitoring, used less cognitive resources, and had a higher degree of automated processing than those with low social adjustment. During the later stages of emotional conflict processing, individuals with low social adjustment showed poorer conflict processing.

Abstract
Evidence suggests that Disgust Sensitivity (DS) is a personality trait that may confer risk for the development of some anxiety-related disorders. To examine the origins of this trait we administered the DS subscale of the Disgust Propensity and Sensitivity Scale-Revised to 90 monozygotic and 90 dizygotic twin pairs, of which 55% were women. The DS subscale consists of two dimensions; Somatic Disgust and Ruminative Disgust. Biometrical modeling techniques were used to estimate heritability of the DS dimensions by sex. For women, each dimension was influenced by a combination of genetic and environmental factors. More specifically, 40.1% of the variance in DS was observed to be due to additive genetic factors and the remaining variance due to non-shared environment. Correlations among DS dimensions for women could be explained by genetic and environmental factors influencing the two dimensions. For men, the two dimensions were influenced by environmental but not genetic factors. These findings suggest that the etiology of DS is complex and arises as a function of dimension-specific and non-specific etiologic factors that vary as a function of sex. The implication of these findings for the sex differences in the etiology of some anxiety-related disorders are discussed.

Abstract
Consumption of insects has gained interest because it may provide a more sustainable and healthier alternative for conventional meat. However, in Western societies, insect consumption is met with resistance due to negative attitudes based on fear and disgust. To further understand consumers' willingness to try insect meat, a 2 (meat type: bovine vs. insect) × 2 (product type: common vs. uncommon) experiment was conducted (n = 130). Four food choice factors were expected to mediate the effect of meat type and product type on willingness to try: health, sensory appeal, risk perception, and disgust. Results indicate that meat type had no effect on willingness to try. Relative to bovine meat, insect meat was perceived as both healthier and more disgusting, which could explain the absence of a meat type effect. Unexpectedly, use of insects in common products (burgers) as compared to uncommon products (skewers) was met with a lower willingness to try. Also, common products with insect meat was considered to be less healthy and more disgusting, compared to uncommon products with insect meat.

Abstract
Disgust propensity (DP) has been conceptualized as a stable personality trait that confers risk for contamination-related OCD (C-OCD). However, the extent to which DP leads to the subsequent development of C-OCD is unclear. In fact, the presence of C-OCD might lead to an increase in DP rather than the inverse. The present study was aimed to test this hypothesis in a large clinical sample of OCD patients (≥ 21 years of age) with (C-OCD; n = 56) and without (NC-OCD; n = 103) contamination-related symptoms that completed measures of OCD symptoms, depression, anxiety, and DP. DP was assessed twice, in reference to the present situation (T1) and to when the participant was 18 years old (T0). The two groups did not significantly differ in DP at T0. However, C-OCD participants reported higher DP scores than NC-OCD at T1. Furthermore, the T1 vs T0 difference in DP was significant only in the C-OCD group. Subsequent analyses also showed that T1 DP levels, but not T0 levels, significantly predicted contamination-related symptoms. Despite study limitations, these findings question the role of DP as a risk factor for C-OCD.

Abstract
From an evolutionary perspective, incestuous behavior is puzzling. The goal of this study was to assess the tenability of the Westermarck hypothesis (1891, 1921)-that people who live in close physical proximity with one another during childhood will develop a sexual indifference or aversion toward one another-and the mediating role of disgust as an incest avoidance mechanism in father-daughter relationships. A sample of fathers with daughters ( N = 632) from Canada and the United States were recruited by Qualtrics-a survey platform and project management company-to complete an online survey. The results from this study did not support the viability of the Westermarck hypothesis as a mechanism that facilitates incest avoidance for fathers. Physical proximity was not associated with incest propensity or disgust toward incest. Less disgust toward incest, however, was found to be associated with more incest propensity. These results indicate that physical proximity may not be a reliable kinship cue used by fathers to inform incest avoidance, but that disgust toward incest may still be a proximate mechanism that facilitates incest avoidance among fathers using kinship cues other than physical proximity.

Abstract
It is often assumed that things that are disgusting to eat are, themselves, disgusting, and that things that are disgusting to eat are also contaminating. We present data that counters both of these assumptions. In adult American and Indian samples, Study 1 provides evidence that, in contrast to many other insects, participants have positive attitudes toward butterflies. Participants are relatively unbothered by touching them or eating food that they have contacted but are very disgusted by the thought of eating them. Study 2 extends these findings with an adult American sample, comparing four pairs of animals, one admired and one disgusting: butterflies and cockroaches, canaries and vultures, koalas and rats, and dogs and hyenas. In all 4 cases, the positive animals themselves are rated as very low in disgustingness but rated as very disgusting to consume-almost as disgusting as the negative animals. However, although contact between the negative animals and a favorite food produces a strong disgust response to the favorite food, this contamination effect is much smaller, and sometimes absent, with the positive animals. We present evidence that the perceived immorality of killing admired animals is related to the disgust at consuming them. Disgust at eating an admired animal may have a moral component because it involves, at least indirectly, killing the animal. An admired animal that has contacted a favored food does not reliably make that food disgusting. In this scenario, as opposed to eating, there is no harm to the animal.

Abstract
Background The generation or persistence of sexual arousal may be compromised when inhibitory processes such as negative emotions, outweigh sexual excitation. Disgust particularly, has been proposed as one of the emotions that may counteract sexual arousal. In support of this view, previous research has shown that disgust priming can reduce subsequent sexual arousal. As a crucial next step, this experimental study tested whether disgust (by means of odor) can also diminish sexual arousal in individuals who are already in a state of heightened sexual excitation. Methodology In this study, participants were all men (N = 78). To elicit sexual arousal, participants watched a pornographic video. Following 4.30 minutes from the start of the video clip, they were exposed to either a highly aversive/disgusting odor (n = 42), or an odorless diluent/solvent (n = 36), that was delivered via an olfactometer, while the pornographic video continued. In both conditions the presentation of the odor lasted 1 second and was repeated 11 times with intervals of 26 seconds. Sexual arousal was indexed by both self-reports and penile circumference. Principal findings The disgusting odor (released when the participants were already sexually aroused) resulted in a significant decrease of both subjective and genital sexual arousal compared to the control (odorless) condition. Significance The finding that the inhibitory effect of disgust was not only expressed in self-report but also expressed on the penile response further strengthens the idea that disgust might hamper behavioral actions motivated by sexual arousal (e.g., poor judgment, coercive sexual behavior). Thus, the current findings indicate that exposure to an aversive odor is sufficiently potent to reduce already present (subjective and) genital sexual arousal. This finding may also have practical relevance for disgust to be used as a tool for self-defence (e.g., Invi Bracelet).

Abstract
Although many studies revealed that emotions and their dynamics have a profound impact on cognition and behavior, it has proven difficult to unobtrusively measure emotions. In the current study, our objective was to distinguish different experiences elicited by audiovisual stimuli designed to evoke particularly happy, sad, fear and disgust emotions, using electroencephalography (EEG) and a multivariate approach. We show that we were able to classify these emotional experiences well above chance level. Importantly, we retained all the information (frequency and topography) present in the data. This allowed us to interpret the differences between emotional experiences in terms of component psychological processes such as attention and arousal that are known to be associated with the observed activation patterns. In addition, we illustrate how this method of classifying emotional experiences can be applied on a moment-by-moment basis in order to track dynamic changes in the emotional response over time. The application of our approach may be of value in many contexts in which the experience of a given stimulus or situation changes over time, ranging from clinical to consumption settings.

Abstract
Multisensory integration (MSI) is crucial for human communication and social interaction and has been investigated in healthy populations and neurodevelopmental disorders. However, the use of stimuli with high ecological validity is sparse, especially in event-related potential (ERP) studies. The present study examined the ERP correlates of MSI in healthy adults using short (500 ms) ecologically valid professional actor-produced emotions of fear or disgust as vocal exclamation or facial expression (unimodal conditions) or both (bimodal condition). Behaviourally, our results show a general visual dominance effect (similarly fast responses following bimodal and visual stimuli) and an MSI-related speedup of responses only for fear. Electrophysiologically, both P100 and N170 showed MSI-related amplitude increases only following fear, but not disgust stimuli. Our results show for the first time that the known differential neural processing of fear and disgust also holds for the integration of dynamic auditory and visual information.

Abstract
The present study examined the internal and external validity of the French version of the 12-item Disgust Propensity and Sensitivity Scale-Revised (DPSS-12) in a nonclinical sample from the general population. Two hundred and eighty-two participants completed the DPSSf-12 questionnaire as well as the Anxiety Sensitivity Index (ASI), Anxiety Trait (STAI B), Obsessional Belief Questionnaire 44 items (OBQ 44), Obsessive Compulsive Inventory-Revised (OCI-R) and Positive and Negative Affect Schedule (PANAS). Confirmatory Factor Analysis supported a 2-factor structure after two sensitivity items were removed. The 10-item scale showed good internal consistency, construct validity and test-retest reliability. These adequate psychometric properties make the DPSSf-10 appropriate for use by researchers and practitioners.

Abstract
To address ongoing debates about whether feelings of disgust are causally related to moral judgments, we pharmacologically inhibited spontaneous disgust responses to moral infractions and examined effects on moral thinking. Findings demonstrated, first, that the antiemetic ginger (Zingiber officinale), known to inhibit nausea, reduces feelings of disgust toward nonmoral purity-offending stimuli (e.g., bodily fluids), providing the first experimental evidence that disgust is causally rooted in physiological nausea (Study 1). Second, this same physiological experience was causally related to moral thinking: ginger reduced the severity of judgments toward purity-based moral violations (Studies 2 and 4) or eliminated the tendency for people higher in bodily sensation awareness to make harsher moral judgments than those low in this dispositional tendency (Study 3). In all studies, effects were restricted to moderately severe purity-offending stimuli, consistent with preregistered predictions. Together, findings provide the first evidence that psychological disgust can be disrupted by an antiemetic and that doing so has consequences for moral judgments.

Abstract
For prepubertal youth, sexual stimuli elicit disgust and avoidance, yet in adolescence this avoidance shifts to sexual approach. One explanation could be that disgust declines in adolescence. This project examined whether disgust is indeed lower in adolescence compared to preadolescence, and whether this difference across age groups would be restricted to sex-relevant disgust elicitors. We also examined whether the strength of disgust would depend on familiarity between participant and source. To examine disgust responses in youths, two cross-sectional studies (N = 248, ages six to 17 years) were conducted using scenario-based measurements. Disgust was overall higher in early adolescence than in preadolescence and relatively weak when the source of disgust was a familiar person. Specifically, when parents were the source, sex-relevant disgust was higher in the groups of early and middle adolescents than in the group of preadolescents. Sex-relevant disgust elicited by a stranger or best friend, however, was lower in middle than in early adolescence. The latter is consistent with the view that repeated confrontation with disgusting stimuli might attenuate disgust, which could contribute to healthy sexual functioning. The heightened sex-relevant disgust in middle adolescents when parents were the source might reflect a functional avoidance mechanism of inappropriate sex mates.

Abstract
One of the most recent and original adaptations of Mary Wollstonecraft (Godwin) Shelley's Frankenstein; or, The Modern Prometheus (1818) is the ballet version choreographed by Liam Scarlett and performed by the Royal Ballet in 2016 and the San Francisco Ballet in 2017 and 2018. What emerges from this translation is an economical, emotionally wrenching, and visually elegant drama of family tragedy from which we can draw a cautionary tale about contemporary bioethical dilemmas in family making that new and forthcoming biomedical technologies present. This performance of bodies interacting suggests the need for an ethics of acceptance and recognition as people navigate complex familial relationships involving procreative liberty, questions of moral personhood, and parental obligation. In the Frankenstein ballet, the narrative genre of dance-what I'll call "story in the flesh"-invites viewers to identify with the characters and enter into the complexity of interpersonal relations. The ballet becomes a compelling testimony about possible unintended outcomes set in motion by well-intended fallible humans like themselves.

Abstract
A sizeable number of studies have documented a relationship between heterosexual persons' experience of disgust (measured as an individual difference variable or induced experimentally) and prejudice toward gay men (i.e., homonegativity). Yet, to date, no one has attempted to meta-analytically review this corpus of research. We address this gap by conducting a meta-analysis of published and unpublished work examining heterosexual men and women's disgust and their homonegativity toward gay men. Fourteen articles (12 published, two unpublished) containing 17 studies were analyzed (N = 7,322). The average effect size for disgust sensitivity studies was moderate to large (d = 0.64), whereas for disgust induction studies, the effect was large (d = 0.77). No evidence of effect size heterogeneity emerged. Future directions and recommendations for methodological improvements are outlined.

Abstract
Throughout evolutionary history, pathogens have imposed strong selection pressures on humans. To minimize humans' exposure to pathogens, a behavioral immune system that promotes the detection and avoidance of disease-connoting cues has evolved. Although most pathogens cannot be discerned by our sensory organs, they produce discernable changes in their environment. As a result, a common denominator of many disease-connoting cues is morphological deviance-figurative disparity from what is normal, visual dissimilarity to the prototype stored in memory. Drawing on an evolutionary rationale, we examine the hypothesis that activation of the behavioral immune system renders people more sensitive to morphological deviance and more prone to perceive dissimilarities between stimuli. In Study 1 ( N = 343), participants who scored higher on disgust sensitivity demonstrated greater differentiation between normal and disfigured faces, reflecting greater sensitivity to morphological deviance in the bodily domain. In Study 2 ( N = 109), participants who were primed with pathogen threat demonstrated greater differentiation between perfect and imperfect geometrical shapes, reflecting greater sensitivity to morphological deviance even in stimuli that have nothing to do with health or disease. In Study 3 ( N = 621), participants who scored higher on disgust sensitivity perceived pairs of neutral pictures as less similar (i.e., more dissimilar) to each other. Literature on the relations to social deviance and implications for social perception and for social behavior is discussed.

Abstract
A 2 × 2 experiment was conducted, where participants watched anti-tobacco messages that varied in deception (content portraying tobacco companies as dishonest) and disgust (negative graphic images) content. Psychophysiological measures, self-report, and a recognition test were used to test hypotheses generated from the motivated cognition framework. The results of this study indicate that messages containing both deception and disgust push viewers into a cascade of defensive responses reflected by increased self-reported unpleasantness, reduced resources allocated to encoding, worsened recognition memory, and dampened emotional responses compared to messages depicting one attribute or neither. Findings from this study demonstrate the value of applying a motivated cognition theoretical framework in research on responses to emotional content in health messages and support previous research on defensive processing and message design of anti-tobacco messages.

Abstract
PURPOSE OF REVIEW In the past 20 years, the role of disgust in anxiety disorders and obsessive-compulsive disorder (OCD) has been investigated with increasing precision. In this review, we examine recent evidence implicating disgust in anxiety and OCD, highlighting recent measurement and methodological improvements. Specific emphasis is placed on understanding the mechanisms that may account for the role of disgust in OCD and related disorders. RECENT FINDINGS Recent developments include clarification of the role of distinct disgust-relevant vulnerabilities in the etiology of anxiety and OCD, an improved understanding of the neurobiology of disgust processing in OCD, and an increased focus on disgust-related mechanisms that contribute to psychopathology, such as disgust-based learning and emotion regulation. Disgust proneness is increasingly linked with symptoms of anxiety and OCD. However, further examination of the mechanisms that account for the roles of distinct disgust-relevant vulnerabilities is needed, and studies that directly examine disgust during the course of treatment are limited. Increasingly, the field has moved toward experimental investigation of specific disgust-relevant mechanisms that influence the etiology and treatment of OCD and related anxiety disorders.

Abstract
Using a combination of personal reflections, published literature, and original empirical research, we argue that the disgust triggered by gay men's sexual practices (specifically, anal intercourse) is a critical, though overlooked, contributor to heterosexual men and women's homonegativity (i.e., negative attitudes and behaviors directed toward men who are or are perceived to be gay). We conclude our article by articulating several directions for future inquiry that we believe will advance current understanding of prejudice and discrimination directed toward gay men.

Abstract
A growing body of research has implicated disgust in various psychopathologies, especially anxiety-related disorders. Although the observed role of disgust in many disorders is robust, the mechanisms that may explain this role are unclear. Cutting-edge research in cognitive science has the potential to elucidate such mechanisms and consequently improve our understanding of how disgust contributes to the etiology and maintenance of psychopathology. In this qualitative review, we systematically assess cognitive bias mechanisms that have been linked to disgust and its disorders. This review suggests that disgust-related biases may be observed in memory, interpretation, judgment of expectancies, and attention, as well as at implicit levels. Of these cognitive domains, the most robust bias appears to be observed at the level of attention. However, reliable moderators of attentional biases for disgust have not yet been identified, and this bias has not been systematically linked to other levels of analysis. Despite these limitations, the available research indicates that attentional avoidance rather than orienting or maintenance may be the most characteristic of disgust. Attentional avoidance of disgust may have important implications for etiological and treatment models of disorders characterized by excessive disgust reactions. The implications for advancing such models are discussed in the context of a combined cognitive bias hypothesis.

Abstract
Consistent with the view that disgust might be involved in persistent body dissatisfaction, there is preliminary evidence showing a positive correlation between measures of negative body image and indices of both trait disgust and self-directed disgust. In two correlational studies among undergraduates (N = 577 and N = 346, respectively) we aimed at replicating and extending these findings by testing a series of critical relationships, which follow from our hypotheses that 1) trait disgust propensity would increase the risk of developing a negative body image by increasing the likelihood of feeling self-disgust, and 2) trait disgust sensitivity would heighten the impact of self-disgust on the development of persistent negative body appraisals. Replicating previous research, both studies showed that negative body image was positively related to self-disgust, disgust propensity and disgust sensitivity. Mediation analyses showed that, in line with our model, self-disgust partly accounted for the association between disgust propensity and negative body image. Although disgust sensitivity showed an independent relationship with body image, disgust sensitivity did not moderate the association between self-disgust and negative body image. All in all, findings are consistent with the view that self-disgust-induced avoidance may contribute to persistent negative body appraisals.

Abstract
Emotion dysregulation, the pervasive difficulty managing negative emotions, is a core problem across mood and anxiety disorders. Anger, shame, and disgust are particularly problematic emotions, impacting both disorder severity and treatment outcome. We previously found that a 16-week dialectical behavior therapy skills training group (DBT-ST) was superior to an activities-based support group (ASG) in decreasing emotion dysregulation in 44 adults with high emotion dysregulation who met diagnostic criteria for an anxiety or depressive disorder. We presently examine these participants' changes in anger, shame, disgust, and distress using self-reports collected over 6 months during and after treatment. Hierarchical linear modeling analyses show that DBT-ST was superior to ASG in decreasing anger suppression (d = 0.93) and distress (d = 1.04). Both conditions significantly reduced shame, disgust propensity, and disgust sensitivity, but neither was superior for these outcomes. The treatments did not significantly reduce anger expression. Mediation analyses suggest that condition indirectly influenced 4-month anger suppression, shame, and distress through its effect on 2-month emotion dysregulation. These findings suggest that DBT-ST is efficacious for certain problematic emotions and distress in depressed and anxious adults and that common factors may account for some, but not all, of its benefits.

Abstract
Disgust has been shown to perform a "disease-avoidance" function in contamination fears. However, no studies have examined the relevance of disgust to obsessive-compulsive (OC) concerns about sexual orientation (e.g., fear of one's sexual orientation transforming against one's will, and compulsive avoidance of same-sex and/or gay or lesbian individuals to prevent that from happening). Therefore, we investigated whether the specific domain of contamination-based disgust (i.e., evoked by the perceived threat of transmission of essences between individuals) predicted OC concerns about sexual orientation, and whether this effect was moderated/amplified by obsessive beliefs, in evaluation of a "sexual orientation transformation-avoidance" function. We recruited 283 self-identified heterosexual college students (152 females, 131 males; mean age = 20.88 years, SD = 3.19) who completed three measures assessing disgust, obsessive beliefs, and OC concerns about sexual orientation. Results showed that contamination-based disgust (β = .17), responsibility/threat overestimation beliefs (β = .15), and their interaction (β = .17) each uniquely predicted OC concerns about sexual orientation, ts = 2.22, 2.50, and 2.90, ps < .05. Post hoc probing indicated that high contamination-based disgust accompanied by strong responsibility/threat overestimation beliefs predicted more severe OC concerns about sexual orientation, β = .48, t = 3.24, p < .001. The present study, therefore, provided preliminary evidence for a "sexual orientation transformation-avoidance" process underlying OC concerns about sexual orientation in heterosexual college students, which is facilitated by contamination-based disgust, and exacerbated by responsibility/threat overestimation beliefs. Treatment for OC concerns about sexual orientation should target such beliefs.

Abstract
BACKGROUND Relative to other body-focused repetitive behaviors, skin-picking has received little investigation. In particular, its association with disgust has hardly been studied. This is surprising because one etiological model of skin-picking disorder (SPD) suggests that the excessive picking is a form of disgust-motivated grooming that aims at the removal of pathogens from the skin. SUBJECTS AND METHODS This questionnaire study explored whether SPD patients (n=46) and healthy controls (n=36) differ in different facets of trait disgust (tendency to experience pathogen disgust, moral disgust, self-disgust, and disgust regulation ability). Moreover, a multiple regression analysis was calculated in order to investigate whether skin-picking symptoms can be predicted based on these components of trait disgust. RESULTS Patients received higher scores on all disgust measures than controls. The degree of patients' skin picking (symptom severity, resulting impairment) could be predicted based on moral disgust (disgust experienced when confronted with moral transgressions) and difficulties in disgust regulation. CONCLUSION This study provides evidence for the role of specific disgust components in SPD.

Abstract
Skin-picking disorder (SPD) is a common mental disorder characterized by recurrent and excessive picking of dermatological irregularities. Different disorder models have been developed to explain this behavior, but empirical evidence is still scarce. One model (the disgust-related disease avoidance model) suggests that SPD might be understood as pathological grooming elicited by skin imperfections that singal possible infection. Twenty-five women with SPD and 19 matched controls viewed and rated images depicting skin irregularities and smooth skin during functional magnetic resonance imaging. The participants did not engage in picking behavior. Relative to controls, SPD patients reported more disgust and urge to pick when looking at skin irregularities. This was accompanied by greater activation in the insula and amygdala, and stronger insula-putamen coupling. Disgust feelings elicited by viewing skin irregularities were positively correlated with activation of the insula and the putamen, in the clinical group. On personality questionnaires, the SPD patients reported elevated self-loathing and problems in regulating their disgust feelings. The current study provides first evidence for altered disgust processing in SPD patients.

Abstract
The extent to which emotionally significant stimuli capture visual attention remains elusive because a preference for reporting or choosing emotionally significant stimuli could mimic attentional capture by these stimuli. We conducted two prior-entry experiments to disentangle whether phobic and fear-relevant stimuli capture attention or merely produce a response bias in spider-fearful participants. Prior entry denotes the effect that attended stimuli are perceived earlier than unattended stimuli as indicated by temporal order judgments. We presented phobic (spiders), fear-relevant (snakes) and neutral stimuli in pairs with varying temporal onset. The participants' task was to indicate which stimulus was presented first (Experiment 1) or second (Experiment 2). In the first experiment, spider-fearful but not control participants indicated that they had perceived spiders as occurring earlier in time, suggesting a prior-entry effect for spiders in this group. But surprisingly, in the second experiment, spider-fearful participants indicated more frequently that they had seen spiders as being presented second. This finding rules out a genuine prior-entry effect and instead suggests a strong preference for the response option associated with the feared animal. This response bias may result from a hypervigilance toward the feared stimulus and contribute to maintaining avoidance behavior in individuals with specific phobias.

Abstract
BACKGROUND Little is known about how emotion recognition may be modified in individuals prone to elicit disgust. OBJECTIVE We sought to determine if subjects with total laryngectomy would present a modified recognition of facial expressions of disgust. METHODS A total of 29 patients presenting with a history of advanced-stage laryngeal cancer were recruited, 17 being surgically treated (total laryngectomy) and 12 treated with chemoradiation therapy only. Based on a validated set of images of facial expressions of fear, disgust, surprise, happiness, sadness and anger displayed by 6 actors, we presented participants with expressions of each emotion at 5 levels of increasing intensity and measured their ability to recognize these emotions. RESULTS Participants with (vs without) laryngectomy showed a higher threshold for the recognition of disgust (3.2. vs 2.7 images needed before emotion recognition, p = 0.03) and a lower success rate of correct recognition (75.5% vs 88.9%, p = 0.03). CONCLUSION Subjects presenting with an aesthetic impairment of the head and neck showed poorer performance in disgust recognition when compared with those without disfigurement. These findings might relate either to some perceptual adaptation, habituation phenomenon, or to some higher-level processes related to emotion regulation strategies.

Abstract
How is emotion represented in the brain: is it categorical or along dimensions? In the present study, we applied multivariate pattern analysis (MVPA) to magnetoencephalography (MEG) to study the brain's temporally unfolding representations of different emotion constructs. First, participants rated 525 images on the dimensions of valence and arousal and by intensity of discrete emotion categories (happiness, sadness, fear, disgust, and sadness). Thirteen new participants then viewed subsets of these images within an MEG scanner. We used Representational Similarity Analysis (RSA) to compare behavioral ratings to the unfolding neural representation of the stimuli in the brain. Ratings of valence and arousal explained significant proportions of the MEG data, even after corrections for low-level image properties. Additionally, behavioral ratings of the discrete emotions fear, disgust, and happiness significantly predicted early neural representations, whereas rating models of anger and sadness did not. Different emotion constructs also showed unique temporal signatures. Fear and disgust - both highly arousing and negative - were rapidly discriminated by the brain, but disgust was represented for an extended period of time relative to fear. Overall, our findings suggest that 1) dimensions of valence and arousal are quickly represented by the brain, as are some discrete emotions, and 2) different emotion constructs exhibit unique temporal dynamics. We discuss implications of these findings for theoretical understanding of emotion and for the interplay of discrete and dimensional aspects of emotional experience.
