Physiological feelings.

The role of peripheral physiology in the experience of emotion has been debated since the 19th century following the seminal proposal by William James that somatic responses to stimuli determine subjective emotion. Subsequent views have integrated the forebrain's ability to initiate, represent and simulate such physiological events. Modern affective neuroscience envisions an interacting network of "bottom-up" and "top-down" signaling in which the peripheral (PNS) and central nervous systems both receive and generate the experience of emotion.

Brief Emotion Regulation Training Facilitates Arousal Control During Sexual Stimuli.

Disgust, a negative emotion which evokes strong behavioral avoidance tendencies, has been associated with sexual dysfunction. Recently, it was postulated that healthy sexual functioning requires a balance between excitatory (increased sexual arousal) and inhibitory processes (lowered disgust levels). This suggests that amplification of excitatory processes (like sexual arousal) could be a valuable addition to treatments for affect-based sexual dysfunctions.

Disgust and Sexual Arousal in Young Adult Men and Women.

Previous research suggested that disgust may interfere with healthy sexual functioning by demonstrating that women with sexual pain disorders are characterized by heightened disgust propensity, relatively strong (physiological and subjective) disgust responses when exposed to sexual stimuli, and relatively strong automatic sex-disgust memory associations. To broaden the understanding of the relationship between sex and disgust, Study 1 tested the relationship between trait disgust and sexual functioning in both men (N = 109) and women (N = 187), and showed that specifically for women both relatively high disgust propensity and high sensitivity were related to lower sexual functioning. Study 2 focused on healthy young adults (N = 19 men and N = 24 women), and tested the relationship between trait disgust and automatic sex-disgust associations as well as the predictive value of trait disgust propensity for participants' level of sexual arousal while watching an erotic video.

Nausea in specific phobia of vomiting.

Specific phobia of vomiting (SPOV) is a clinical condition with early onset, chronic course and substantial psychosocial impairment due to a rigorous avoidance behavior. A primary symptom which drives patients to consult a medical practitioner is nausea. In this study our aim was to further analyze this symptom of SPOV and examined its role in the development and manifestation of the phobia.

Giving in to arousal or staying stuck in disgust? Disgust-based mechanisms in sex and sexual dysfunction.

Sex and disgust seem like strange bedfellows. The premise of this review is that disgust-based mechanisms nevertheless hold great promise for improving our understanding of sexual behavior, including dysfunctions. Disgust is a defensive emotion that protects the organism from contamination.

The Sexual Disgust Questionnaire; a psychometric study and a first exploration in patients with sexual dysfunctions.

Introduction: Disgust may be involved in sexual problems by disrupting sexual arousal and motivating avoidance of sexual intercourse. To test whether heightened disgust for sexual contaminants is related to sexual dysfunctions, the Sexual Disgust Questionnaire (SDQ) has recently been developed. Previous research showed that particularly women with vaginismus display a generally heightened dispositional disgust propensity and heightened disgust toward stimuli depicting sexual intercourse.

Sympathetic and parasympathetic responses to a core disgust video clip as a function of disgust propensity and disgust sensitivity.

It is generally assumed that disgust is accompanied by increased activation of the parasympathetic nervous system (PNS). However, empirical support for the role of PNS in disgust is scarce. This study tested whether (i) activation of the PNS is indeed involved in disgust and (ii) disgust-induced autonomic activation is especially pronounced in individuals with high disgust propensity or enhanced disgust sensitivity.

The Multi-Dimensional Blood/Injury Phobia Inventory: its psychometric properties and relationship with disgust propensity and disgust sensitivity.

The Multi-Dimensional Blood Phobia Inventory (MBPI; Wenzel & Holt, 2003) is the only instrument available that assesses both disgust and anxiety for blood-phobic stimuli. As inflated levels of disgust propensity (i.e.

Contamination and harm relevant UCS-expectancy bias in spider phobic individuals: influence of treatment.

Phobic individuals expect aversive UCS's following encounters with phobic stimuli. Previous research using a thought-experiment procedure showed that contamination rather than harm-related outcome expectancies differentiated best between high and low spider fearful undergraduates. This study investigated the alleged role of these UCS-expectancy biases in the maintenance of phobic complaints.

Disgust and fear-related UCS-expectancy bias in blood-fearful individuals.

People with specific fears tend to overestimate the occurrence of unpleasant consequences in situations involving their feared objects. Such expectancy bias logically acts in a way to confirm phobic fear and avoidance. Increasing evidence suggests that blood phobia is qualitatively different from other specific phobias.

Expectancy bias and the persistence of posttraumatic stress.

Anxious individuals tend to overestimate the probability that encounters with anxiogenic stimuli (CS) will be followed by aversive consequences (UCS). This study examined whether such (biased) UCS expectancies predict the persistence of PTSD symptoms. A total of 265 soldiers were recruited before a four-month deployment to Iraq in 2004.

Disgust and contamination sensitivity in vaginismus and dyspareunia.

This study examined the potential role of disgust propensity and contamination sensitivity in vaginismus. Women suffering from vaginismus (n = 20) or dyspareunia (n = 22), and a group of women without sexual complaints (n = 30) completed self report measures indexing their (1) general dispositional disgust propensity, and (2) sensitivity for (ideational) contamination by sexual stimuli as a function of its source (self, partner, unknown). In support of the idea that disgust may be involved in vaginismus, women with vaginistic complaints displayed a generally enhanced dispositional disgust propensity.

An internet-based study on the relation between disgust sensitivity and emetophobia.

In the etiology of disgust-relevant psychopathology, such as emetophobia (fear of vomiting), two factors may be important: disgust propensity, i.e., how quickly the individual experiences disgust, and disgust sensitivity, i.

Differential UCS expectancy bias in spider fearful individuals: evidence toward an association between spiders and disgust-relevant outcomes.

Recently, differential UCS expectancies were found for high- and low-predatory fear-relevant animals [Davey, G. C. L.
