A disgust mood state causes a negative interpretation bias, but not in the specific domain of body-related concerns

The present study was designed to examine the effects of a disgust mood state on negative interpretation bias, in particular in the domain of body and weight concerns. Participants (N = 120) were randomly assigned to one of four mood induction groups (i.e., disgust, anxiety, happy, and neutral) and were afterwards asked to respond to various types of ambiguous scenarios to index general threat interpretations, negative body-related interpretations, and neutral/positive interpretations. Results demonstrated that both the anxiety and disgust mood induction groups displayed higher levels of negative interpretations of the ambiguous threat scenarios than the neutral and happy groups. However, no evidence was obtained for a negative interpretation bias in the body-related domain for these negative mood groups, and this conclusion was also true for participants scoring high on a scale of eating disorder symptoms. Altogether, these findings suggest that disgust does not play a role in eating pathology by inducing a negative interpretation bias in the specific domain of body and weight concerns.     

Social anxiety and interpretation biases for facial displays of emotion: emotion detection and ratings of social cost

The current study assessed the processing of facial displays of emotion (Happy, Disgust, and Neutral) of varying emotional intensities in participants with high vs. low social anxiety. Use of facial expressions of varying intensities allowed for strong external validity and a fine-grained analysis of interpretation biases. Sensitivity to perceiving negative evaluation in faces (i.e., emotion detection) was assessed at both long (unlimited) and brief (60 ms) stimulus durations. In addition, ratings of perceived social cost were made indicating what participants judged it would be like to have a social interaction with a person exhibiting the stimulus emotion. Results suggest that high social anxiety participants did not demonstrate biases in their sensitivity to perceiving negative evaluation (i.e. disgust) in facial expressions. However, high social anxiety participants did estimate the perceived cost of interacting with someone showing disgust to be significantly greater than low social anxiety participants, regardless of the intensity of the disgust expression. These results are consistent with a specific type of interpretation bias in which participants with social anxiety have elevated ratings of the social cost of interacting with individuals displaying negative evaluation.     

Le dégoût dans le trouble obsessionnel compulsif,mécanismes, évaluation,implications pour des pistes thérapeutiques

IntroductionAlthough considered a basic emotion, disgust has received little attention from research from the psychology of emotions compared to other emotions such as fear or sadness.Literature findingsMany empirical and experimental data suggest, however, that disgust plays a determining role not only in our ability to adapt to our environment but also in the maintenance and development of certain psychopathological states such as obsessive-compulsive disorders. The purpose of this article is to review the literature on the construct of disgust, including its two basic dimensions of disgust and disgust. A first part will be dedicated to the acquisition of disgust in the framework of evaluative and Pavlovian learning, we will then describe in detail the assessment tools available in the literature allowing to evaluate the different dimensions, then we will address the continuum. Experience of disgust, from normal disgust to pathological disgust, and will particularly target its role in dysfunctional obsessions of contamination and emotional distress.DiscussionIf, from a theoretical point of view, the understanding of the underlying mechanisms of pathological disgust reactions improves, the proposals for treatment to mitigate these reactions are rare. New approaches to care will be described to allow the development of empirically based psychological interventions.ConclusionThe recognition of emotional influences beyond anxiety in obsessive-compulsive disorder (OCD) stems from the fundamental importance of a dimensional approach to psychopathology and support. The accumulated data suggest that the inclusion of disgust in the theoretical models of OCD, in particular those with contamination concern, will thus improve our understanding and treatment of this disorder.     

Individual differences in pathogen disgust predict men’s,but not women’s,preferences for facial cues of weight

Previous research suggests that people who score higher on measures of pathogen disgust demonstrate (1) stronger preferences for healthy individuals when assessing their facial attractiveness and (2) stronger negative attitudes about obese individuals. The relationship between pathogen disgust and attractiveness judgments of faces differing in cues of weight has yet to be investigated, however. Here we found that men’s, but not women’s, pathogen disgust was positively correlated with their preference for facial cues of lower weight. Moreover, this effect of pathogen disgust was independent of the possible effects of moral and sexual disgust. These data implicate pathogen disgust in individual differences in preferences for facial cues of weight, at least among men, and suggest that the sex-specific effects of pathogen disgust on preferences for facial cues of weight may be different to those previously reported for general negative attitudes about obese individuals.     

Disgust,scrupulosity and conservative attitudes about sex: Evidence for a mediational model of homophobia

In the present study, core disgust predicted negative attitudes toward homosexuals even after controlling for contamination fear. The effect of core disgust on negative attitudes toward homosexuals was indirect, partially mediated by conservative sexual attitudes and religiosity. The effects of religious principles on negative attitudes toward homosexuals were indirect, via conservative sexual beliefs. These results establish a link between disgust and negative attitudes towards homosexuals that is not fully accounted for by contamination concerns, but rather is partially accounted for by conservative sexual ideology and religiosity.     

Contamination vs. harm-relevant outcome expectancies and covariation bias in spider phobia

There is increasing evidence that spiders are not feared because of harmful outcome expectancies but because of disgust and contamination-relevant outcome expectancies. This study investigated the relative strength of contamination- and harm-relevant UCS expectancies and covariation bias in spider phobia. High (n=25) and low (n=24) spider fearful individuals saw a series of slides comprising spiders, pitbulls, maggots, and rabbits. Slides were randomly paired with either a harm-relevant outcome (electrical shock), a contamination-related outcome (drinking of a distasting fluid), or nothing. Spider fearful individuals displayed a contamination-relevant UCS expectancy bias associated with spiders, whereas controls displayed a harm-relevant expectancy bias. There was no evidence for a (differential) postexperimental covariation bias; thus the biased expectancies were not robust against refutation. The present findings add to the evidence that contamination ideation is critically involved in spider phobia.     

Emotion-specific and emotion-non-specific components of posttraumatic stress disorder (PTSD): implications for a taxonomy of related psychopathology

Many cognitive theories of posttraumatic stress disorder (PTSD), including our own SPAARS model, propose that one basis of the disorder is the cognitive system's persistent failure to resolve discrepancies between trauma-related information and the content of pre-existing mental representations, such as schemas. This leads to the characteristic PTSD symptom pattern of re-experiencing and avoidance of trauma-related material. Furthermore, the nature of this unresolved discrepancy revolves around appraisals of threat and the corresponding emotion profile in PTSD is therefore predominantly intense fear and anxiety. This paper argues that this general framework can be extended to discrepancies around other appraisal dimensions such as loss, and consequently to other emotions such as sadness. A localized taxonomy is therefore proposed comprising emotional disorders that resemble PTSD in their basic patterns of re-experiencing and avoidance symptoms--what we call their 'emotion-non-specific component'--but that differ from PTSD in terms of the core emotions involved--what we call their 'emotion-specific component'. The clinical and nosological implications of this argument are discussed.     

Experienced disgust causes a negative interpretation bias: a causal role for disgust in anxious psychopathology

This paper reports the results of an experiment investigating the effect of induced disgust on interpretational bias using the homophone spelling task. Four groups of participants experienced a disgust, anxiety, happy or neutral mood induction and then completed the homophone spelling task which requires the participant to interpret ambiguous words presented through headphones. Both the disgust and anxiety groups interpreted significantly more threat/neutral homophones as threat than both the happy and neutral groups; the disgust group also interpreted significantly fewer positive/neutral homophones as positive than the happy group. These findings are consistent with the view that induced disgust causes a negative interpretational bias which is similar to that reported for anxiety. The results could not be interpreted in terms of the disgust induction concurrently raising levels of self-reported anxiety, but could be interpreted in terms of disgust maintaining existing levels of anxiety. The effect of disgust was to facilitate negative interpretations rather than emotional interpretations regardless of valence. These findings provide the basis for a causal role for disgust in anxious psychopathology. Because the effect is a non-specific emotion-congruent one, elevated disgust levels will result in a predisposition to interpret information in a threatening way across a broad range of anxious- and threat-relevant domains.     

A clean self can render harsh moral judgment

Physical cleanliness has many medical benefits, such as protection from the dangers of contagion. We explore a potential unintended consequence of cleanliness. Given the metaphorical association between physical cleanliness and moral purity (Zhong & Liljenquist, 2006), we contend that a clean self may also be linked to a virtuous self. This enhanced moral self-perception can in turn license harsher moral judgment. Three experiments found that cleanliness, whether induced via physical cleansing or through a visualization task, licensed severe judgment on morally contested issues such as abortion and pornography. Further, we found that an inflated moral self mediated the relationship between cleanliness and moral judgment. These results provide unique insight to the social significance of cleanliness and may have important implications for discrimination and prejudice.
