The neurobiological mechanisms of nocebos are still poorly understood. Thirty-eight women participated in a 'smell study' using functional magnetic resonance imaging. They were presented with an odorless stimulus (distilled water) together with the verbal suggestion that this fluid has an aversive odor which enhances disgust feelings. The nocebo was presented while the participants viewed disgusting, fear-inducing, and neutral images. Participants' affective and neuronal responses during nocebo administration were compared with those in a control condition without nocebo...

Obsessive-compulsive disorder (OCD) patients show increased insula activation to disgust-inducing images compared to healthy controls (HC). We explored whether this disgust reactivity was also present in the olfactory domain by conducting the first fMRI study of olfaction in OCD. Neural activation in response to pleasant and unpleasant odors (vs. unscented air) was investigated in 15 OCD and 15 HC participants using fMRI. OCD participants (vs. HC) had increased left anterior insula activation to unpleasant odors (vs...

What leads children to moralize actions that cause no apparent harm? We hypothesized that adults' verbal instruction ("testimony"), as well as emotions such as disgust, would influence children's moralization of apparently harmless actions. To test this hypothesis, 7-year-old children were asked to render moral judgments of novel, seemingly victimless, body-directed or nature-directed actions after being exposed to adults' testimony or to an emotional induction. Study 1 demonstrated that children became more likely to judge actions as "wrong" upon being verbally presented with testimony about disgust or anger-but not upon being directly induced to feel disgusted...

: Although a few measures of disgust propensity are available in Italy, most of them take a long time to administer and/or have not shown replicable and sound psychometric properties. In the current study, the authors developed an Italian nine-item self-report measure of disgust propensity (particularly of pathogen disgust)-the Disgust Propensity Questionnaire (DPQ)-to address the limitations of currently available measures. In Study 1, the DPQ was developed through exploratory and confirmatory factor analyses from an initial pool of 33 items that were administered to 784 nonclinical participants...

BACKGROUND: Difficulties with the regulation of negative affect have been extensively studied in neuroimaging research. However, dysregulation of a specific emotion, disgust, has hardly been investigated. In the present study, we used voxel-based morphometry to identify whether gray matter volume (GMV) of frontal regions is correlated with personality traits associated with general and disgust-specific emotion regulation difficulties. METHOD: We analyzed T1-weighted images of 49 females (mean age = 22...

Research has shown that brain regions mediating disgust (e.g., the insula) become activated when viewing others' disgust, a response mediated, perhaps by the mirror neuron system or the Theory of Mind module. In a novel behavioral experiment, we explore vicarious disgust and relief, in individuals with obsessive-compulsive disorder (OCD) symptoms. Participants (N = 10) provided disgust ratings to self-contamination or watching the contamination of an experimenter; and to the experimenter washing his own hands after the subjects had been contaminated...

Growing evidence shows that consumer choices in real life are mostly driven by unconscious mechanisms rather than conscious. The unconscious process could be measured by behavioral measurements. This study aims to apply automatic facial expression analysis technique for consumers' emotion representation, and explore the relationships between sensory perception and facial responses. Basic taste solutions (sourness, sweetness, bitterness, umami, and saltiness) with 6 levels plus water were used, which could cover most of the tastes found in food and drink...

Suicide risk is highly prevalent among individuals with posttraumatic stress disorder (PTSD). Self-disgust, defined as disgust directed internally and comprised of disgust with oneself (disgusting self) and with one's behaviors (disgusting ways), may impact this increased risk. The present study examined self-disgust as a putative mechanism linking PTSD symptoms with suicide risk. A sample of 347 trauma-exposed undergraduates completed measures of PTSD symptoms, suicide risk, self-disgust, and depressive symptoms...

Facial expressions are important for humans in communicating emotions to the conspecifics and enhancing interpersonal understanding. Many muscles producing facial expressions in humans are also found in domestic dogs, but little is known about how humans perceive dog facial expressions, and which psychological factors influence people's perceptions. Here, we asked 34 observers to rate the valence, arousal, and the six basic emotions (happiness, sadness, surprise, disgust, fear, and anger/aggressiveness) from images of human and dog faces with Pleasant, Neutral and Threatening expressions...

BACKGROUND: This study aimed to explore the characteristics of event-related potentials induced by facial emotion recognition in patients with first-episode schizophrenia and in their siblings. METHODS: In this case-control study, 30 first-episode schizophrenia patients, 26 siblings, and 30 healthy controls were enrolled. They completed facial emotion recognition tasks from the Ekman Standard Faces Database as an induction for evoked potentials. Evoked potential data were obtained using a 64-channel electroencephalography system...

The stimulus sets presently used to study emotion processing are primarily static pictures of individuals (primarily adults) making emotional facial expressions. However, the dynamic, stereotyped movements associated with emotional expressions contain rich information missing from static pictures, such as the difference between happiness and pride. We created a set of 1.1 s dynamic emotional facial stimuli representing boys and girls aged 8-18. A separate group of 36 individuals (mean [M] age = 19.5 years, standard deviation [SD] = 1...

Being touched is known to affect emotion, and even a casual touch can elicit positive feelings and affinity. Psychophysiological studies have recently shown that tactile primes affect visual evoked potentials to emotional stimuli, suggesting altered affective stimulus processing. As, however, these studies approached emotion from a purely unidimensional perspective, it remains unclear whether touch biases emotional evaluation or a more general feature such as salience. Here, we investigated how simple tactile primes modulate event related potentials (ERPs), facial EMG and cardiac response to pictures of facial expressions of emotion...

Why do people expose themselves to certain emotional stimuli and avoid others? We propose that what people want to feel is linked to attitudes toward emotions. In 3 studies, we show that individuals with more (vs. less) negative attitudes toward an emotion were more (vs. less) likely to avoid stimuli that induce that emotion. People who evaluated disgust (or joy) less favorably than others were less likely to expose themselves to disgusting (or joyful) pictures (Study 1). These links were emotion-specific and could not be explained by differences in state or trait emotion (Study 2) or in emotional reactivity (Study 3)...

Previous studies support a link between moral disgust and impurity, whereas anger is linked to harm. We challenged these strict correspondences by showing that disgust is activated in response to information about moral character, even for harm violations. By contrast, anger is activated in response to information about actions, including their moral wrongness and consequences. Study 1 examined disgust and anger in response to an action that suggests bad moral character (animal cruelty) versus an action that is seen as inherently more wrong (domestic abuse)...

Emotions are highly influential to many psychological processes. Indeed, research employing emotional stimuli is rapidly escalating across the field of psychology. However, challenges remain regarding discrete evocation of frequently co-elicited emotions such as amusement and happiness, or anger and disgust. Further, as much contemporary work in emotion employs college students, we sought to additionally evaluate the efficacy of film clips to discretely elicit these more challenging emotions in a young adult population using an online medium...

For the rejection of disgusting and potentially health-threatening food, the sense of smell plays a critical role. We conducted two experiments in order to investigate the role of gender and trait disgust (the temporally stable tendency to experience disgust across different situations) on disgust-related olfactory processing. A total of 40 men and women (Study 1), as well as a group of women divided according to high versus low trait disgust (Study 2, n = 59), were compared with regard to their odor thresholds for carbon disulfide (which smells like spoiled food) and a control stimulus ( n-butanol)...

The perception of disgust is a powerful but yet puzzling emotion, aiming at the prevention of potential microbial pathogens and being directly linked to olfactory processing in its neurophysiological pathways via the anterior insular cortex. In sample of healthy participants with a natural variation in olfactory function, we investigated the relation between olfactory sensitivity and disgust perception. A total of 123 healthy individuals were surveyed with a disgust sensitivity questionnaire. Olfactory threshold was assessed in all participants using the Sniffin' Sticks...

Substantial evidence suggests influence of color, physical state, and other extrinsic features on consumer perception and acceptability of food products. In this study, 560 subjects evaluated liking and emotional responses associated with 5 sweeteners (sucralose, stevia, saccharin, aspartame, and sucrose) under 2 eliciting conditions: control (brand name only) and informed (brand name/packet image), to assess impact of the packet color. For a given condition, 5 identical tea samples each labeled with a sweetener type were rated for sweetness and overall liking (9-point) and emotions (5-point)...

BACKGROUND: Exposure to advertisements for tobacco products and tobacco warning labels evokes emotions. This study evaluated the association of discrete positive and negative emotions with interest in alternative tobacco products. METHOD: In 2013, 1,226 U.S. adult nonsmokers and current smokers viewed advertisements for moist snuff, snus, and electronic cigarettes (e-cigarettes) with various warning labels and then indicated their emotional responses in terms of anger, anxiety, sadness, guilt, disgust, discouragement, hope, and contentment...

Inadequate hand hygiene is estimated to result in nearly 300,000 deaths annually, with the majority of deaths being among children younger than 5 years. In an effort to promote handwashing with soap and water treatment behaviors among highly susceptible household members of cholera patients, we recently developed the Cholera-Hospital-Based Intervention-for-7-Days (CHoBI7); chobi means picture in Bengali. This 1-week handwashing with soap and water treatment intervention is delivered by a promoter in the hospital and the home to cholera patients and their household members...
