厌恶情绪与自杀行为的关系

自杀导致人类死亡的人数与日俱增,然而自杀的心理机制却并不清楚。最近研究发现,厌恶情绪是导致自杀的主要情绪因素,个体因为自身厌恶而走向自杀。厌恶情绪是一种对自己和他人排泄物等反感的基本情绪,促进个体远离毒性和疾病,从而产生“免疫行为”。许多心理问题来自于对周围人或事物的厌恶,有自杀行为的个体对自身极其厌恶,说明他们的厌恶情绪出现了问题。如同躯体免疫攻击自身一样,自身厌恶是自杀意念的关键因素,早年创伤是其根源,生活压力和精神疾病也参与厌恶诱发自杀意念。厌恶诱发自杀意念的神经基础与HPA轴和五羟色胺系统有关。未来研究可利用神经影像和电生理等神经科学技术,检验自杀行为的神经机制,探讨厌恶情绪影响自杀行为的心理和神经机制。     

The effect of disgust on preference for structure: Evidence for a double‐sided response

The literature on emotions converges on the idea that people cope with the undesired effects of disgust through an immediate response of avoidance aimed to the physical and psychological rejection of any contamination threat. However, previous research does not consider what happens after this immediate response. We investigate the dual response to disgust and propose that disgust generates an immediate preference for structure, but also an opposite, subsequent tendency to prefer unstructured stimuli. Our reasoning is based on the mobilization‐minimization theory, which suggests opposed reactions to negative emotions. We demonstrate that, while immediate reactions to disgust imply preference for structured logos, after the disgust‐eliciting stimulus is eliminated from the environment, people show higher preference for visually unstructured logos. The study of the dual response to disgust offers novel insights to consumer behavior, decision‐making, and emotion literature, showing that a typically avoidance‐triggering emotion, that is, disgust, can then lead to opposite effects in terms of preference for structure.     

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.     

The relationship between disgust sensitivity, anxiety and obsessions

Three hundred participants, including volunteers from an obsessional support group, filled in questionnaires relating to disgust sensitivity, health anxiety, anxiety, fear of death, fear of contamination and obsessionality as part of an investigation into the involvement of disgust sensitivity in types of obsessions. Overall, the data supported the hypothesis that a relationship does exist between disgust sensitivity and the targeted variables. A significant predictive relationship was found between disgust sensitivity and total scores on the obsessive compulsive inventory (OCI; Psychological Assessment 10 (1998) 206) for both frequency and distress of symptomatology. Disgust sensitivity scores were significantly related to health anxiety scores and general anxiety scores and to all the obsessional subscales, with the exception of hoarding. Additionally, multiple regression analyses revealed that disgust sensitivity may be more specifically related to washing compulsions: frequency of washing behaviour was best predicted by disgust sensitivity scores. Washing distress scores were best predicted by health anxiety scores, though disgust sensitivity entered in the second model. It is suggested that further research on the relationship between disgust sensitivity and obsessionality could be helpful in refining the theoretical understanding of obsessions.     

Evidence for a curvilinear relationship between complexity and originality

The present study tested the hypothesis of a curvilinear relationship between preference for complexity and each of two components of creativity—originality and fluency—for four complexity levels within the upper half of the complexity distribution The hypothesis was based on an interpretation of extremely high complexity levels as emphasizing rejection of conventionality more than fondness for novelty and tolerance of ambiguity The results not only supported the main hypothesis of a curvilinear relationship but also suggested that originality and fluency declined beyond the second level of complexity studied. Question is cast on the assumption that increasing complexity is necessarily productive of increasing creativity Lastly, the results were interpreted as also being consistent with Berlyne's (1967) hypothesis that moderate increases in arousal are most conducive to learning     

Anxiety and Depression: Evidence for the Differentiation of Commonly Cooccurring Constructs

Anxiety and depression frequently cooccur diagnostically. This observation has led researchers to investigate whether anxiety and depression can be meaningfully distinguished as unique theoretical constructs or whether they are better conceptualized as features of a general psychological distress. In the present study, we attempted to differentiate self-reported state and trait anxiety from depression in a university sample (N = 593) using the Beck Depression Inventory (BDI) and the Endler Multidimensional Anxiety Scales (EMAS). In addition, we examined the relationship among self-reported anxiety, depression, and neuroticism to determine the extent to which the Anxiety and Depression facet scales of the NEO Personality Inventory—Revised represent distinct and mutually exclusive measures of anxiety and depression. Principal-components analyses and a series of multiple regression models were used to conduct this investigation. Results indicate that both state and trait anxiety and depression can be reliably differentiated with the BDI and the EMAS. Results also suggest that invoking a single general distress factor to explain the strong interrelationships between anxiety and depression in nonclinical samples is premature.     

The relationship between physical appearance concerns,disgust, and anti-fat prejudice

This study examined relationships between physical appearance concerns (fear of fat, body image disturbance; BIDQ), disgust, and anti-fat prejudice (dislike, blame), and tested whether disgust mediates relationships between physical appearance concerns and anti-fat prejudice. Participants (N = 1649; age = 28 years) provided demographic data and completed measures of anti-fat prejudice, tendency to feel disgust, and physical appearance concerns. Univariate, multivariate, and mediation analyses were conducted. Univariate and multivariate associations were found between fear of fat, BIDQ, disgust, and anti-fat prejudice for women. For women only, mediation analyses showed that disgust partially mediated relationships between physical appearance concerns and dislike of fat people. For men, univariate and multivariate relationships were found between fear of fat, and dislike and blame of fat people, but disgust was not related to anti-fat prejudice. Newer constructs centering on physical appearance concerns and disgust appear promising candidates for understanding anti-fat prejudice.     

Evidence for a relationship between trait gratitude and prosocial behaviour

Prosocial behaviour towards unrelated others is communally beneficial but can be individually costly. The emotion of gratitude mitigates this cost by encouraging direct as well as “upstream” reciprocity, thereby facilitating cooperation. A widely used method for measuring trait gratitude is the Gratitude Questionnaire (GQ6) [McCullough, M., Emmons, R., &; Tsang, J. (2002). The grateful disposition: A conceptual and empirical topography. Journal of Personality and Social Psychology, 82, 112–127. Retrieved from https://doi.org/10.1037/0022-3514.82.1.112]. Here we undertake an assessment of the external validity of the GQ6 by examining its relationship with two incentivized economic games that serve as face valid indices of generosity and reciprocity. In two studies (total N?=?501) we find that trait gratitude as measured by the GQ6 predicts greater donations in a charity donation task as well as greater transfers and returns in an incentivized trust game. These results support the hypothesis that individuals with higher trait gratitude are more generous and trusting on average, and provide initial evidence as to the predictive validity of the GQ6.

Attentional bias differences between fear and disgust: Implications for the role of disgust in disgust-related anxiety disorders

Research demonstrates a relation between disgust and anxiety-related pathology; however, research has yet to reveal mechanisms by which disgust may contribute to anxiety. The current experiment examined attentional bias characteristics as one route by which disgust influences anxiety. Eighty undergraduate participants completed a rapid serial visual presentation attention task using fear, disgust, or neutral target stimuli. Task-relevance of the target's presentation was also manipulated. Results revealed that task-relevant disgust targets impaired attention among all participants, but task-irrelevant disgust targets impaired attention only in high disgust prone individuals. Difficulty in disengagement characterised both disgust and fear attentional biases, but the difficulty in disengagement was greater for disgust compared to fear attentional biases. High disgust prone individuals displayed exaggerated difficulty in disengaging attention from disgust targets compared to low disgust prone individuals. The results suggest that disgust attentional biases differ from fear attentional biases. The characteristics of disgust attentional biases are discussed as possible mechanisms by which disgust functions in certain anxiety disorders.     

Analysing the relationship between target-to-target and distractor-to-target repetitions: Evidence for a common mechanism

In the present study an assumption of retrieval theories of negative priming was tested. In particular, retrieval theories assume that the same underlying process causes benefits in target-to-target repetition trials and cost effects in distractor-to-target repetition trials in selection tasks in which targets are accompanied by distractor stimuli. More specifically, retrieval theories predict a negative correlation: The higher the benefit in target-to-target repetition trials is, the higher the cost effect in distractor-to-target repetition trials should be. In fact, in a study with considerable power (N = 110) and a design that allowed a confound-free detection of correlations, I observed a significant negative correlation between benefit and cost effects. This result is interpreted as evidence for a common retrieval mechanism.     

Integrating Etiological Models of Social Anxiety and Depression in Youth: Evidence for a Cumulative Interpersonal Risk Model

Models of social anxiety and depression in youth have been developed separately, and they contain similar etiological influences. Given the high comorbidity of social anxiety and depression, we examine whether the posited etiological constructs are a correlate of, or a risk factor for, social anxiety and/or depression at the symptom level and the diagnostic level. We find core risk factors of temperament, genetics, and parent psychopathology (i.e., depression and anxiety) are neither necessary nor sufficient for the development of social anxiety and/or depression. Instead, aspects of children’s relationships with parents and/or peers either mediates (i.e., explains) or moderates (i.e., interacts with) these core risks being related to social anxiety and/or depression. We then examine various parent- and peer-related constructs contained in the separate models of social anxiety and depression (i.e., parent–child attachment, parenting, social skill deficits, peer acceptance and rejection, peer victimization, friendships, and loneliness). Throughout our review, we report evidence for a Cumulative Interpersonal Risk model that incorporates both core risk factors and specific interpersonal risk factors. Most studies fail to consider comorbidity, thus little is known about the specificity of these various constructs to depression and/or social anxiety. However, we identify shared, differential, and cumulative risks, correlates, consequences, and protective factors. We then put forth demonstrated pathways for the development of depression, social anxiety, and their comorbidity. Implications for understanding comorbidity are highlighted throughout, as are theoretical and research directions for developing and refining models of social anxiety, depression, and their comorbidity. Prevention and treatment implications are also noted.     

The Interaction of Extraversion and Anxiety Sensitivity on Social Anxiety: Evidence of Specificity Relative to Depression

Neuroticism and extraversion have been linked to the etiologies and course of anxiety and mood disorders, such that neuroticism is broadly associated with numerous disorders and extraversion is most strongly associated with social anxiety and depression. While previous research has established the broad associations between temperament and emotional disorders, less is known about the specific, proximal factors that are associated with them, and very few studies have situated these risk factors into a larger etiological model that specifies how they may relate to one another. The current study examined the interaction of extraversion and anxiety sensitivity (AS) in predicting social anxiety symptoms in a large, diagnostically diverse clinical sample (N = 826). Symptoms were assessed with self-report and dimensional interview measures, and regression analyses were performed examining the main effects and interaction of extraversion and AS (examining both total and lower-order components) on social anxiety. Results showed that at higher levels of AS, the inverse relationship between extraversion and social anxiety was stronger, and the social concerns component of AS is responsible for this effect. This interaction was also observed with regard to depression symptoms, but the interaction was not present after accounting for shared variance (i.e., comorbidity) between depression and social anxiety symptoms. Clinical and theoretical implications of the results are discussed.     

The Nature of the Association between Anxiety Sensitivity and Pain-Related Anxiety: Evidence from Correlational and Intervention Studies

High anxiety sensitivity (AS) has been associated with elevated pain-related anxiety in anxiety and pain samples. The present study investigated (a) the associations among the lower order dimensions of AS and pain-related anxiety, using a robust measure of AS, and (b) the pain-related anxiety outcomes of a telephone-delivered cognitive behavioural treatment (CBT) designed to reduce high AS. Participants were 80 anxiety treatment-seeking participants with high AS (M age = 36 years; 79% women). After providing baseline data on AS and pain-related anxiety, participants were randomly assigned to an eight-week telephone CBT or a waiting list control. At baseline, bivariate correlations showed AS physical and cognitive, but not social, concerns were significantly associated with pain-related fear and arousal but not escape/avoidance behaviours. Multiple regression revealed that after accounting for emotional distress symptoms, AS physical, but not cognitive or social, concerns uniquely predicted pain-related anxiety. Multilevel modelling showed that the AS-targeted CBT reduced pain-related anxiety and treatment-related changes in global AS and AS physical concerns mediated changes in pain-related anxiety. Results suggest that an AS-targeted intervention may have implications for reducing pain-related anxiety. Further research is needed in a chronic pain sample.

Metacognitive Therapy for Generalized Anxiety Disorder: Nature,Evidence and an Individual Case Illustration

Metacognitive therapy (MCT) is based on over 25 years of research focusing on the processes that contribute to the development and maintenance of psychological disorders. The approach identifies a common set of processes in psychopathology, and MCT shows promising results in effectively treating a range of disorders. This paper presents the central theoretical tenets of MCT and uses a clinical vignette to illustrate the structure and techniques of treatment based on Wells's (2009) manual as they relate to a specific case of generalized anxiety disorder.     

A feel for disgust: tactile cues to pathogen presence

One function of disgust is to act as a pathogen-avoidance system preventing contact with substances harbouring disease-causing organisms. Avoiding pathogens, however, requires systems for their detection. Whereas previous research on disgust has focused on visual and olfactory detection cues, one largely overlooked modality is touch. Here we examine whether tactile cues play a role in pathogen detection and activate the disgust response. Participants briefly touched and then rated stimuli varying along dimensions predicted to correlate with pathogen presence: moisture, temperature, and consistency. Results show that participants rated wet stimuli and stimuli resembling biological consistencies as more disgusting than dry stimuli and stimuli resembling inanimate consistencies, respectively. No main effect for temperature was found. We report on predicted interactions, the relationship between disgust ratings and perceived infection risk, and individual differences. Taken together, these data suggest that touch is an important modality providing information for disgust-related processes.
