Anxiety regarding contracting COVID-19 related to interoceptive anxiety sensations: The moderating role of disgust propensity and sensitivity

The COVID-19 public health crisis has led to extensive recommendations by officials to contain its spread. Anxiety regarding contracting the virus is prominent in the public. Specific routes to anxiety over disease contraction are under studied. It is expected that a contributory feature of fear of contracting COVID-19 involve disgust propensity and sensitivity, emotional reactions that are part of a broader behavioral immune system (BIS). A total of N = 908 Chinese adults (mean age = 40.37 years, SD = 9.27; n = 752 female) participated in a survey distributed between February 24 and March 15, 2020. Participants completed measures of anxiety sensitivity, disgust propensity and sensitivity, and fear of contracting COVID-19. Results support a moderating relationship between both disgust propensity and sensitivity in the relationship between physical concerns associated with anxiety sensitivity and fear of contracting COVID-19. These results lend support for individual variation in the activation of the BIS. Recommendations for public education to target individuals who may experience mental health consequences from pandemics are provided.

Modulating disgust in mental contamination: Experimental evidence for the role of disgust

Background and objectivesDisgust has been associated with mental contamination (MC), although the evidence has hitherto been nonexperimental. Furthermore, strategies that can target both disgust and MC have not been well explored. We investigated the role of disgust in MC by inducing disgust via olfaction within the “dirty kiss” paradigm and conversely, to see if pairing pleasant olfactory stimulus during re-exposure, based on counterconditioning, can reduce MC. We also examined whether disgust constructs (propensity and sensitivity) and trait MC are associated with state MC arising from the “dirty kiss”. MethodsMC was first evoked using the “dirty kiss” paradigm, in which participants (N = 90) visualized receiving a non-consensual kiss from a physically dirty man (time 1). After a break, participants repeated the “dirty kiss” task in a room that was scented to smell either disgusting, pleasant or neutral (time 2). Participants completed measures of disgust and trait MC after the experiment. ResultsParticipants in the disgust condition reported increased feelings of dirtiness at time 2. Disgust propensity predicted feelings of dirtiness at time 1. Disgust sensitivity and trait MC were not associated with state MC indices. LimitationsThe use of a non-clinical female sample, extraneous factors during the break and contextual factors arising from room change at time 2 are some potential limitations. ConclusionsInduced disgust within a MC paradigm resulted in increased feelings of dirtiness, suggestive of disgust-based emotional reasoning. Pairing pleasant olfactory stimulus was not effective at attenuating MC or disgust.

Emotional Reaction to Fear- and Disgust-Evoking Snakes: Sensitivity and Propensity in Snake-Fearful Respondents.

This paper continues our previous study in which we examined the respondents’ reaction to two morphologically different snake stimuli categories – one evoking exclusively fear and another evoking exclusively disgust. Here we acquired Likert-type scale scores of fear and disgust evoked by the same snake stimuli by a total of 330 respondents. Moreover, we collected data about the respondents’ age, gender, education, snake fear [Snake Questionnaire (SNAQ)], and disgust propensity [Disgust Scale-Revised (DS-R)], and we analyzed the effect of these variables on the emotional scores (with special focus on snake-fearful respondents). In addition, we collected the SNAQ and DS-R scores from the respondents tested in the previous study using the rank-ordering method to directly compare the results of these two approaches. The results showed that non-fearful respondents give high scores of fear to the fear-eliciting snakes and high scores of disgust to the disgust-eliciting snakes, but they give low scores of the other emotional dimension (disgust/fear) to each. In contrast, snake-fearful respondents not only give higher fear and disgust scores to the respective snake stimuli, but they also give high scores of fear to the disgust-eliciting snakes and high scores of disgust to the fear-eliciting snakes. Both Likert-scale scores and rank-ordering data show that the clear border dividing both snake stimuli categories dissolves when evaluated by the snake-fearful respondents.

Validation of the Serbian Translation of the Disgust Propensity and Sensitivity Scale (DPSS)

Disgust represents a feeling of revulsion and is manifested as a response to adverse stimuli and indicates a motivation to withdraw from the stimulus. Several attempts were made to measure disgust, the earliest being the Disgust Sensitivity Scale (Haidt et al., 1994) that relied on responses to disgust elicitors, and the Disgust Propensity and Sensitivity Scale (DPSS, Cavanagh & Davey, 2000) that focused on the feeling itself, not on the strength of the reaction to specific disgust elicitors. There are two proposed models of the DPSS, one with two subscales, disgust propensity (DP) and disgust sensitivity (DS), and the other with three subscales where the self-focused/ruminative disgust (SFR) split from DS. This study aimed to validate the Serbian translation of the scale. We used two samples, a student sample (N = 437) and a social network user sample (N = 344). We used confirmatory factor analysis in both samples and the yielded results have shown that the three-factor solution is superior. The internal consistency of the subscales was marginally acceptable, while SFR subscale alpha value lagged in the social network user sample. Significant gender differences in subscale values were detected as expected, adding to the scale validity. Also, DP and DS registered a weak positive correlation with trait Neuroticism, negative affect, stress, depression, and anxiety. These results will further our claims that our translation of the DPSS is valid. In conclusion, we believe that the Serbian translation of the 12 item DPSS scale is viable for use in future research on this subject.

Disgust propensity has a causal link to the stigmatization of people with cancer.

Disgust-driven stigma may be motivated by an assumption that a stigmatized target presents a disease threat, even in the absence of objective proof. Accordingly, even non-contagious diseases, such as cancer, can become stigmatized by eliciting disgust. This study had two parts: a survey (n = 272), assessing the association between disgust traits and cancer stigma; and an experiment, in which participants were exposed to a cancer surgery (n = 73) or neutral video (n = 68), in order to test a causal mechanism for the abovementioned association. Having a higher proneness to disgust was associated with an increased tendency to stigmatize people with cancer. Further, a significant causal pathway was observed between disgust propensity and awkwardness- and avoidance-based cancer stigma via elevated disgust following cancer surgery exposure. In contrast, those exposed to cancer surgery not experiencing elevated disgust reported less stigma than controls. Exposure-based interventions, which do not elicit disgust, may be profitable in reducing cancer stigma.

The role of disgust propensity and sensitivity on sexual excitations and inhibition in obsessive-compulsive disorder.

Sexuality is understudied in Obsessive-Compulsive Disorder (OCD). According to the Dual Control Model, low sexual excitation (SE) and high sexual inhibition (SI) are indicative of a higher probability of experiencing a sexual dysfunction. The present study investigated SE and SI in OCD patients compared with controls. It was hypothesized that OCD patients report lower SE and higher SI than controls. Given their potential role as inhibitors of sexual response, it was hypothesized that in the OCD group higher disgust propensity/sensitivity, contamination/washing symptoms, unacceptable thoughts, and obsessive beliefs predicted lower SE, higher SI due to Threat of Performance Failure, and higher SI due to Threat of Performance Consequences. Seventy-two OCD patients and 72 controls matched on gender/age completed the Disgust Propensity and Sensitivity Scale-Revised, Obsessive Beliefs Questionnaire-46, Obsessive Compulsive Inventory- Revised, and Sexual Inhibition/Sexual Excitation Scales. OCD patients had higher SE, SI due to Threat of Performance Failure, and SI due to Threat of Performance Consequences than controls. In the OCD group, higher disgust sensitivity, SI due to Threat of Performance Consequences, and perfectionism predicted higher SI due to Threat of Performance Failure. Higher SI due to Threat of Performance Failure and contamination/washing symptoms predicted higher SI due to Threat of Performance Consequences. These findings highlight the presence of sexual difficulties in OCD patients, particularly a higher SE and SI. The latter is especially relevant in those patients with higher disgust sensitivity, contamination/washing symptoms and perfectionism. Psychotherapists should assess and target sexuality during clinicalpractice with OCD patients.

Specificity of Disgust in the Prediction of Behavioral Avoidance of Possible Contaminants

Individual differences related to disgust have been implicated in a host of psychiatric disorders, including obsessive–compulsive disorder (OCD). Theory suggests that individual differences in disgust propensity and, perhaps, sensitivity, make individuals more prone to experience disgust when confronted with potential contaminants, which then motivates avoidance of possible contaminants or safety behaviors aimed at removing contaminants when avoidance is not possible. However, no study has concurrently examined the relations of disgust propensity and state disgust with avoidance of contaminant-based stimuli. The present study recruited a sample of 90 undergraduate participants and utilized a multimodal assessment (including self-reported disgust and a behavioral approach task using possible contaminants) to examine the direct and indirect effects of disgust propensity, disgust sensitivity, trait anxiety, state disgust, and state anxiety on avoidance of the stimuli. Results suggested disgust propensity was the only individual difference variable to significantly correlate with avoidance. Although state disgust and state anxiety were significantly correlated with disgust propensity and avoidance, only state disgust significantly mediated the effects of disgust propensity on avoidance. These findings suggest that disgust propensity and state disgust may lead to avoidance of possible contaminants, thereby perpetuating contamination fears and aversions. As such, these results have implications for the etiology of contamination-based OCD. Additional research with clinical samples and more objective measures of state emotional experiences are needed.

Effects of "Dirty" Information on Disgust Responding to an Unknown Animal in Children: The Moderating Role of Maternal Disgust Proneness

Although research has shown that disgust facilitates avoidance of small animals among adults, much less is known about disgust appraisals of small animals in children as well as the predictors of such appraisals. To address this gap, children (ages 5–13) were exposed to dirt-related and cleanliness-related information about unknown animals. The extent to which these types of information influenced children's feelings of fear, disgust, positivity, and avoidance behavior in relation to the animals was examined. The present study then examined the extent to which child and maternal disgust proneness predicted feelings of disgust to the ‘dirty’ animal. The findings show that providing dirt-related information resulted in a significant increase in disgust, but not fear, responding to the animal. Dirt-related information also resulted in a significant decrease in positive feelings toward the animal. Conversely, providing cleanliness-related information resulted in a significant decrease in disgust, but not fear, responding to the animal. In addition, providing cleanliness-related information resulted in a significant increase in positive feelings toward the animal. Children also engage in more avoidance of the animal described as dirty compared to the animal described as clean. In addition, subsequent analysis revealed an interaction between child and maternal disgust propensity in predicting learned disgust to the dirty animal such that the highest levels of feelings of disgust to the dirty animal were observed among children with high disgust proneness who also have mothers with high disgust proneness. The implications of these findings for conceptualizing the role of disgust in animal phobias among youth will be discussed.

Effects of vicarious disgust learning on the development of fear, disgust, and attentional biases in children.

Fear and disgust are defensive emotions that have evolved to protect us from harm. Whereas fear is thought to elicit an instinctive response to deal with immediate threat, disgust elicits immediate sensory rejection to avoid contamination. One mechanism through which disgust and fear may be linked is via attentional bias toward threat. Attentional bias is a well-established feature of anxiety disorders and is known to increase following vicarious fear learning. However, the contribution of vicarious learning to the development of disgust-related attentional biases is currently unknown. Furthermore, the influence of individual differences in disgust propensity and disgust sensitivity on fear and disgust responses has not been investigated in the context of vicarious learning. Therefore, 53 children aged 7-9 years were randomly assigned to receive either fear vicarious learning or disgust vicarious learning. Children's fear beliefs, disgust beliefs, avoidance preferences, and attentional bias were measured at baseline and postlearning. Findings demonstrated increased fear and disgust responding to stimuli following disgust and fear vicarious learning. Crucially, the study provided the first evidence that disgust vicarious learning can create an attentional bias for threat in children similar to that created via fear vicarious learning. However, there was no relationship between disgust propensity and sensitivity and vicariously acquired increases in fear, disgust, and attention. In conclusion, both fear and disgust vicarious learning can create attentional bias, allowing rapid detection of potentially harmful stimuli. This effect could contribute to fear development and is found even in children who are not particularly high in disgust proneness. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

It’s not queasy being green: The role of disgust in willingness-to-pay for more sustainable product alternatives

Scholars differ in the extent to which they regard the “yuck factor” as an important predictor of sustainable consumption decisions. In the present decision experiment we tested whether people’s disgust traits predicted relative willingness-to-pay (WTP) for sustainable product alternatives, including atypically-shaped fruit and vegetables; insect-based food products; and medicines/drinks with reclaimed ingredients from sewage. In a community sample of 510 participants (255 women), using path analyses we examined the extent to which effects of disgust traits on WTP were mediated by cognitive appraisals of perceived taste, health risk, naturalness, visual appeal, and nutritional/medicinal value. Further, we assessed whether these effects were moderated by the tendency to regulate disgust using reappraisal and suppression techniques. Across all product categories, when controlling for important covariates such as pro-environmental attitudes, we found a significant negative effect of trait disgust propensity on WTP. In total, a 1 SD increase in participants’ disgust propensity scores predicted between 6% and 11% decrease in WTP. Appraisals of perceived naturalness, taste, health risk, and visual appeal significantly mediated these effects, differing in importance across the product categories, and explaining approximately half of the total effect of disgust propensity on WTP. Little-to-no support was found for moderation of effects by trait reappraisal or suppression. Individual differences in disgust are likely to be a barrier for certain viable sustainable alternatives to prototypical products. Marketing interventions targeting consumer appraisals, including in particular the perceived naturalness and taste, of these kinds of products may be effective.

Sex differences in the etiology of disgust sensitivity: A preliminary behavioral genetic analysis

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.

Measuring harm avoidance, incompleteness, and disgust in youth with obsessive-compulsive disorder and anxiety disorders

Alongside harm avoidance, incompleteness and disgust have been proposed as important emotion-related motivators underlying the symptoms of obsessive-compulsive disorder (OCD). The aim of the present study was to investigate the validity of self-report and interview-based measures of these constructs in youth with OCD (N = 100) and anxiety disorders (N = 96). All participants completed self-report measures of trait-level harm avoidance and incompleteness (Obsessive-Compulsive Trait Core Dimensions Questionnaire; OCTCDQ) and a measure of trait-level disgust propensity (Disgust Emotion Scale for Children; DES-C). Participants with OCD were also interviewed about the role that harm avoidance, incompleteness, and disgust played in their moment-to-moment experience of symptoms using a modified version of the Obsessive-Compulsive Core Dimensions Interview (OC-CDI). All measures exhibited theoretically sound factor structures and good internal consistency. Self-report scores for harm avoidance and incompleteness were significantly correlated with scores on the interview-based measure of these emotions in current OCD symptoms. A weaker relationship was observed for disgust. The OCTCDQ, DES-C, and OC-CDI appear to be valid for use with clinically-referred youth, and may be useful when studying the etiology, phenomenology, and course of pediatric OCD. More work is needed to better understand how trait-level aspects of disgust relate to moment-to-moment experiences of disgust in OCD.

The 5-Factor Disgust Scale

Abstract. For years, disgust was conceptualized as a disease-avoidance mechanism. However, research shows that socio-moral or sexual transgressions elicit disgust, too. Until now, no German-language disgust scale has covered all disgust factors discussed in the literature. Here we present an economic Five-Factor Disgust Scale (5-FES; Fünf-Faktoren Ekelskala) along with empirical evidence from three studies corroborating its reliability and validity. Two well-established disgust questionnaires were combined and extended with other disgust-relevant items. Using item reduction and exploratory factor analysis, death-related, moral, food-related, sexual, and pathogen disgust emerged as distinct factors (Study 1: N = 456). Confirmatory factor analysis with two large samples (Study 2: N = 997 and N = 405) demonstrated a good fit of the correlated five-factor solution. The 5-FES correlated weakly with neuroticism, anxiety, and social desirability. A high negative correlation between sexual disgust and sexual openness emerged. Criterion validity was shown using self-reported behaviors (Study 3: N = 203). With food-related disgust comprising items about non-spoiled but exotic foods, a new disgust domain emerged. Results indicate that the 5-FES is a comprehensive and psychometrically sound German-language instrument for the differentiated assessment of disgust propensity.

Psychometric Properties, Factor Structure, and Evidence for Measurement Invariance in the Greek Version of the Disgust Scale-Revised (DS-R).

The Disgust Scale has been designed to measure disgust propensity—the individual ease in experiencing disgust. The present study aimed to explore the validity, reliability, the factor structure, and the measurement invariance of the Greek version of the Disgust Scale-Revised (DS-R). A sample of 754 healthy participants completed the Greek version of the DS-R. A subset (n = 363) also completed the revised Symptom checked list and the Eysenck Personality Questionnaire, in order to examine the concurrent validity. Exploratory and Confirmatory factor analyses in different subsets were used to examine the factor structure. Multiple indicators–multiple causes model (MIMIC) models were used to assess the measurement invariance across gender and age. Demographic influences were assessed using t-tests, ANOVA, and Pearson’s correlations. Exploratory factor analysis concluded to two and three factor models, with a factor structure similar to the ones proposed in the literature. Confirmatory factor analysis and bi-factor analysis provided evidence in favor of the three-factor solution. Measurement invariance test revealed differences in six items across gender, and three items across age. The psychometric properties of the factors were satisfactory. Demographic influences on the responses were present, especially with respect to gender. The Greek version of the DS-R demonstrated satisfactory psychometric properties, making it suitable for use for the Greek population.

Disgust assessment: Factorial structure and psychometric properties of the French version of the Disgust Propension and Sensibility Scale Revised-12.

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.

Determining the relationship between alexithymia, skin sensitivity, and disgust

Alexithymia represents an individual's inability to recognize their own or someone else's emotions and also the inability to communicate them. It has a documented influence on many cognitive and emotional activities of human life. Skin and touch are two of the primary vehicles for conveying emotions between individuals. It is on account of the connection between these elements that this study has focused on determining more precisely the relation between skin related satisfaction and disgust and alexithymia. In total 357 students participated in the survey, 286 (82.9%) were female and the average participant age was 20.54 (min=19; max=26; SD=1.24). Apart from this demographical information, the survey consisted of the Skin Satisfaction Questionnaire (TSD-Q 30), the Toronto Alexithymia Questionnaire (TAS-20), and the Disgust Propensity and Sensitivity Questionnaire (DPSS). Based on an analysis of the survey results, Alexithymia was shown to correlate strongly with the shame aspect of skin satisfaction, but only with TAS-20 factors 1 and 2. A weak correlation was demonstrated between positive disgust and alexithymia. Though only a weak correlation, or no correlations as all, between touch satisfaction and alexithymia was established, touch satisfaction and shame accounted for 21.2% of alexithymia variance, while disgust measurement scales accounted for only 1.3%. Out of skin satisfaction parameters, alexithymia appeared to be most strongly connected with shame. Disgust parameters were shown to have a very weak influence on alexithymia variance. Although skin is one of the primary sense organs and touch is capable of conveying emotion, there was found only a weak correlation between, and measured influence of, satisfaction with skin and alexithymia.

Aversive images cause less perceptual interference among violent video game players: evidence from emotion-induced blindness

ABSTRACTPrevious research has assessed links between violent video game playing, aggression, and desensitization in the moral domain, but here we find that frequent violent video game play additionally may be linked with differences in perceptual processing. In an emotion-induced blindness task – wherein graphic images typically outcompete and impair perception of targets – violent video game players suffered less perceptual disruption following aversive images than non-players did, despite no group difference following neutral images. This difference persisted when controlling for sex and other violent media consumption and despite no group differences in trait aggression, disgust propensity, or disgust sensitivity. Importantly, the recruitment method ensured that participants were not aware of links between the experiment and their videogame playing history. Although a causal relationship has yet to be established, the findings suggest that violent video game players might sometimes, literally see the world differently.

Relationship Between Disgust Propensity and Contamination Obsessive-Compulsive Symptoms: The Mediating Role of Information Processing Bias

Background: Early studies showed that disgust contributes to developing the contamination obsessive-compulsive disorder (C-OCD) and fear of contamination. Despite considering disgust to explain the fear of contamination as a symptom of C-OCD, there are few studies on the mediating role of information processing bias (IPB) in the relationship between disgust propensity (DP) and the fear of contamination. Objectives: The current study aimed at exploring the mediating role of IPB between DP and fear of contamination. Methods: The current descriptive-analytical study was conducted on 386 students selected by cluster sampling method. The employed tools were disgust propensity and sensitivity scale-revised (DPSS-R), the Padua inventory (PI), obsessive beliefs questionnaire (OBQ), and spatial cueing task. Data were analyzed with Amos-22 software. Bootstrap methods were used to analyze the mediating role. Results: Results of the structural equation modeling (SEM) indicated that the proposed model had a good fitness GFI (goodness of fit index), TLI (the Tucker-Lewis index), and CFI (comparative fit index) > 0.95 and RMSEA (root mean square error of approximation) = 0.03. The results showed that the relationship between DP and fear of contamination was mediated by IPB. Conclusions: Results indicated the impact of disgust propensity on fear of contamination through information processing. These findings emphasized that information processing is essential to explain C-OCD. © 2018, Author(s).

Is Heightened Disgust Propensity Truly a Risk Factor for Contamination-Related Obsessive-Compulsive Disorder?

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.

Disgust as a mechanism for decision making under risk: Illuminating sex differences and individual risk-taking correlates of disgust propensity.

The emotion disgust motivates costly behavioral strategies that mitigate against potentially larger costs associated with pathogens, sexual behavior, and moral transgressions. Because disgust thereby regulates exposure to harm, it is by definition a mechanism for calibrating decision making under risk. Understanding this illuminates two features of the demographic distribution of this emotion. First, this approach predicts and explains sex differences in disgust. Greater female disgust propensity is often reported and discussed in the literature, but, to date, conclusions have been based on informal comparisons across a small number of studies, while existing functionalist explanations are at best incomplete. We report the results of an extensive meta-analysis documenting this sex difference, arguing that key features of this pattern are best explained as one manifestation of a broad principle of the evolutionary biology of risk-taking: for a given potential benefit, males in an effectively polygynous mating system accept the risk of harm more willingly than do females. Second, viewing disgust as a mechanism for decision making under risk likewise predicts that individual differences in disgust propensity should correlate with individual differences in various forms of risky behavior, because situational and dispositional factors that influence valuation of opportunity and hazard are often correlated across multiple decision contexts. In two large-sample online studies, we find consistent associations between disgust and risk avoidance. We conclude that disgust and related emotions can be usefully examined through the theoretical lens of decision making under risk in light of human evolution.
