Perceptions that arise from stimulation of olfactory and trigeminal receptors in the nasal cavity guide the evaluation of chemical environment in humans. Strong interindividual differences in these assessments may be attributed to nonsensory factors such as gender, anxiety, and chemical sensitivity. Knowledge regarding the influence of these factors originates mainly from basic odor research using short-term exposure scenarios. In situations with continuous chemical exposures-common in the working environment-their impact is less clear...

Two types of contamination fear are recognized: contact and mental contamination. Contact contamination appears to be motivated both by harm avoidance and disgust avoidance. This study aimed to examine the relationships between disgust propensity, mental contamination and contact contamination while differentiating between harm avoidance and disgust avoidance in contact contamination. 169 OCD patients completed a set of questionnaires assessing mental contamination, contact contamination, disgust propensity, OCD, anxiety and depression...

Extraversion-introversion is a personality dimension referring to individual differences in social behavior. In the past, neurobiological research on extraversion was almost entirely based upon questionnaires which inform about the explicit self-concept. Today, indirect measures are available that tap into the implicit self-concept of extraversion which is assumed to result from automatic processing functions. In our study, brain activation while viewing facial expression of affiliation relevant (i.e., happiness, and disgust) and irrelevant (i...

BACKGROUND AND OBJECTIVES: Cognitive theories suggest that cognitive biases may be related and together influence the anxiety response. However, little is known about the interrelations of cognitive bias tasks and whether they allow for an improved prediction of fear-related behavior in addition to self-reports. This study simultaneously addressed several types of cognitive biases in children, to investigate attention bias, interpretation bias, memory bias and fear-related associations, their interrelations and the prediction of behavior...

Although some studies suggest that the association between disgust proneness (DP) and obsessive-compulsive symptoms (OCS) is specific to the contamination subtype, others suggest that DP is associated with OCS more broadly. To examine if the discrepant findings may partially reflect differences in self-report measures used, this investigation employed structural equation modeling to examine the association between DP and OCS in three samples that completed different combinations of measures of DP, OCS, and anxiety/negative affect...

Research demonstrates that women experience disgust more readily and with more intensity than men. The experience of disgust is associated with increased attention to disgust-related stimuli, but no prior study has examined sex differences in attention to disgust facial expressions. We hypothesised that women, compared to men, would demonstrate increased attention to disgust facial expressions. Participants (n = 172) completed an eye tracking task to measure visual attention to emotional facial expressions...

Although disgust proneness has been implicated in obsessive-compulsive disorder (OCD), there is a paucity of research examining change in disgust proneness during treatment as well as the correlates of such change, especially in children. This study examined the relationship between changes in disgust proneness and disorder-specific symptoms during residential treatment among youth with OCD, anxiety, and mood disorders. Youth ages 12-18 (n=472) completed pre- and post-outcome measures of OCD, anxiety, and mood symptoms and disgust proneness...

The Disgust Propensity and Sensitivity Scale-Revised is one of the most widely used measures of individual differences for the emotion of disgust. It consists of 2 subscales: disgust propensity and disgust sensitivity. This study examined the factor structure, reliability, and validity of the Japanese version of the revised Disgust Propensity and Sensitivity Scale. Japanese participants (N = 1067) completed the scale as well as the Padua Inventory, Anxiety Sensitivity Index, State-Trait Anxiety Inventory, and Positive and Negative Affective Schedule...

Severe health anxiety is characterized by a debilitating fear of somatic illness, and avoidance of disease-related stimuli plays a key role in the maintenance of the disorder. The aim of this study was to investigate severe health anxiety within an evolutionary disease-avoidance framework. We hypothesized that, compared to healthy controls, participants with severe health anxiety would perceive others as sicker, more contagious, and less attractive. We also expected individuals with severe health anxiety to be more prone to avoid interaction with persons who appeared sick, as well as to respond with more health-related worry, more disgust, and more anxiety when confronting such individuals...

OBJECTIVES: Evidence suggests that disgust responses, known to negatively affect psychological wellbeing, may differ in people with cancer. We performed the first quantitative investigation of three discrete types of disgust trait - disgust propensity, sensitivity and self-directed disgust - in people diagnosed with a broad range of cancers (versus cancer-free controls), and explored their associations with psychological wellbeing. DESIGN: In a cross-sectional survey design, 107 participants with heterogeneous cancer diagnoses, recruited from cancer charities and support groups, were matched with cancer-free controls by age and gender...

Research has demonstrated large differences in the degree to which direct and indirect measures predict each other and variables including behavioural approach and attentional bias. We investigated whether individual differences in the co-variance of "implicit" and "explicit" spider fear exist, and whether this covariation exerts an effect on spider fear-related outcomes. One hundred and thirty-two undergraduate students completed direct and indirect measures of spider fear/avoidance, self-report questionnaires of psychopathology, an attentional bias task, and a proxy Behavioural Approach Task...

Several discrete emotions have broad theoretical and empirical importance, as shown by converging evidence from diverse areas of psychology, including facial displays, developmental behaviors, and neuroscience. However, the measurement of these states has not progressed along with theory, such that when researchers measure subjectively experienced emotions, they commonly rely on scales assessing broad dimensions of affect (positivity and negativity), rather than discrete emotions. The current manuscript presents four studies that validate a new instrument, the Discrete Emotions Questionnaire (DEQ), that is sensitive to eight distinct state emotions: anger, disgust, fear, anxiety, sadness, happiness, relaxation, and desire...

BACKGROUND: Disgust is thought to play a prominent role in multiple anxiety disorders and fears, including spider phobia, though little attention has been given to specific treatment strategies that may be effective for multiple disgust-based fears. AIMS: In the present study, we evaluated contamination-focused exposure as a potential transdiagnostic treatment strategy for disgust-based fears in a spider fearful sample. METHOD: Women with significant spider fear were randomized to three 30-minute sessions of exposure therapy involving repeated contact with a dirt mixture (n=17) or a waitlist control condition (n=17)...

In social environments the smile can be driven by different motives and convey different emotions. This makes a smiling face ambiguous and amenable to alternative interpretations. We investigated how social anxiety is related to trustworthiness evaluation of morphed dynamic smiling faces depending on changes in the eye expression. Socially anxious and non-anxious participants judged the un/trustworthiness of people with different smiles. Social anxiety was related to reduced trustworthiness of (a) faces with a neutral mouth unfolding to a smile when the eyes were neutral at the beginning or end of the dynamic sequence, and (b) faces with a smiling mouth when happy eyes slightly changed towards neutrality, surprise, fear, sadness, disgust, or anger...

This study evaluated the psychometric properties of the Child Disgust Scale (CDS) among 457 youth (ages 8-17, M = 14.77 ± 1.98 years) initiating residential treatment for obsessive-compulsive disorder and anxiety disorders. Confirmatory factor analysis supported a bifactor model with two distinct factors of Disgust Avoidance and Disgust Affect, in addition to an overall General Disgust factor. Strong internal consistency was observed for the CDS total and factor scores. In addition, CDS scores demonstrated generally modest and positive correlations with child-reported obsessive-compulsive and anxiety symptoms, weaker correlations with parent-reported anxiety and child-rated impairment, and non-significant correlations with parent-rated impairment...

Different variables have been associated with the development/ maintenance of contamination-related obsessive-compulsive disorder (OCD), although the relevance of these factors has not been clearly established. The present study aimed to analyze the relevance and specificity of these variables. Forty-five women with high scores on obsessive-compulsive contamination symptoms (n = 16) or checking symptoms (n = 15), or non-clinical scores (n = 14) participated in a behavioral approach/avoidance task (BAT) with a contamination-OCD stimulus...

BACKGROUND: The concept of facial emotion recognition is well established in various neuropsychiatric disorders. Although emotional disturbances are strongly associated with somatoform disorders, there are a restricted number of studies that have investigated facial emotion recognition in somatoform disorders. Furthermore, there have been no studies that have regarded this issue using the new diagnostic criteria for somatoform disorders as somatic symptoms and related disorders (SSD)...

Converging evidence has linked the anterior mid-cingulate cortex to negative affect, pain and cognitive control. It has previously been proposed that this region uses information about punishment to control aversively motivated actions. Studies on the effects of lesions allow causal inferences about brain function; however, naturally occurring lesions in the anterior mid-cingulate cortex are rare. In two studies we therefore recruited 94 volunteers, comprising 15 patients with treatment-resistant depression who had received bilateral anterior cingulotomy, which consists of lesions made within the anterior mid-cingulate cortex, 20 patients with treatment-resistant depression who had not received surgery and 59 healthy control subjects...

OBJECTIVE: There have, as yet, been few experimental studies of explicit facial affect recognition in patients with dissociative seizures (DS). The aim of the study was to examine explicit recognition and physiological responses to facial expressions in this group, relative to healthy controls. METHODS: Forty patients with DS and 43 controls completed a computerized test of facial affect recognition, including five basic expressions (happiness, anger, disgust, fear, neutral)...

Attention bias to threat (e.g., disgust faces) is a cognitive vulnerability factor for social anxiety occurring in early stages of information processing. Few studies have investigated the relationship between social anxiety and attention biases, in conjunction with emotional and cognitive responses to a social stressor. Elucidating these links would shed light on maintenance factors of social anxiety and could help identify malleable treatment targets. This study examined the associations between social anxiety level, attention bias to disgust (AB-disgust), subjective emotional and physiological reactivity to a social stressor, and subsequent post-event processing (PEP)...
