Fear of crime and community concerns: Mediating effect of risk and pragmatic fear

This study investigates the relationship between community concerns (i.e., perceived crime, incivilities, and infrastructure) and fear of crime (FOC) while examining the mediating role of risk of victimisation and pragmatic fear. Gender and ethnic differences were also explored. Data were collected using a proportionate multistage random sample of 3,003 participants from a southern Caribbean island in 2015. The following self‐reported measures were used: risk of victimisation and FOC scales, a general (noncrime) fear scale measuring pragmatic fear, and a community concern scale. Data were analysed using path analysis, Sobel tests, and multiple group analysis. Findings revealed that perceived crime and incivilities significantly predicted FOC, whereas infrastructure was insignificant as a direct predictor. Females had higher FOC, and among ethnic groups, Indo‐Trinidadians had the highest FOC than Afro‐Trinidadians and Mixed participants. Risk of victimisation and pragmatic fear had significant mediating effects on community concerns and FOC. Findings are discussed in the context of the social psychology of social disorganisation and previous research.     

Thinking styles and risky decision‐making: Further exploration of the affect–probability weighting link

People usually overweight small probabilities and underweight large probabilities leading to the familiar inverse S‐shaped weighting function. This research explores the link between affect and the structure of probability weighting from the perspective of thinking dispositions, a concept central to dual system theories of reasoning. The effects of affective priming and cognitive load on both probability weighting and the value function are also examined. The evidence suggests that thinking styles do have predictive implications for risky decision‐making. Participants with a more affective thinking style tend to be more risk‐seeking in small probability gambles. However, increasing access to the affective system by affective priming or cognitive load manipulations tend to reduce risk‐seeking behavior in small probability gambles as well as reduce risk averse behavior in large probability gambles. Previous research, manipulating the affective nature of lottery outcomes, found evidence for an increase in curvature (more overweighting of small probabilities and more underweighting of large probabilities) of the weighting function for affect‐rich outcomes, lending support to a hope‐and‐fear deconstruction of probability weighting. The present research suggests that increased anticipatory emotions characterized by the elevation of the weighting function (more overweighting at all probabilities) is also important and could sometimes be more significant than hope‐and‐fear in decision‐making under risk. An integrated approach incorporating the impact of affect on all three, the elevation and curvature of probability weighting as well as the curvature of the value function explains the empirical findings.

Skin-transmitted pathogens and the heebie jeebies: evidence for a subclass of disgust stimuli that evoke a qualitatively unique emotional response

Skin-transmitted pathogens have threatened humans since ancient times. We investigated whether skin-transmitted pathogens were a subclass of disgust stimuli that evoked an emotional response that was related to, but distinct from, disgust and fear. We labelled this response “the heebie jeebies”. In Study 1, coding of 76 participants’ experiences of disgust, fear, and the heebie jeebies showed that the heebie jeebies was elicited by unique stimuli which produced skin-crawling sensations and an urge to protect the skin. In Experiment 2,350 participants’ responses to skin-transmitted pathogen, fear-inducing, and disgust-inducing vignettes showed that the vignettes elicited sensations and urges which loaded onto heebie jeebies, fear, and disgust factors, respectively. Experiment 3 largely replicated findings from Experiment 2 using video stimuli (178 participants). Results are consistent with the notion that skin-transmitted pathogens are a subclass of disgust stimuli which motivate behaviours that are functionally consistent with disgust yet qualitatively distinct.     

Thinking high but feeling low: An exploratory cluster analysis investigating how implicit and explicit spider fear co-vary

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. TwoStep cluster analysis using implicit and explicit spider fear as criterion variables resulted in three clusters: (1) low explicit/low implicit; (2) average explicit/high implicit; and (3) high explicit/low implicit. Clusters with higher explicit fear demonstrated greater disgust propensity and sensitivity and less willingness to approach a spider. No differences between clusters emerged on anticipatory approach anxiety or attentional bias. We discuss results in terms of dual-systems and cognitive–behavioural models of fear.     

Emotion regulation of fear and disgust: differential effects of reappraisal and suppression

Although excessive fear has been central to traditional conceptualisations of the anxiety disorders, recent research suggests that disgust may also play a role in the development of some anxiety disorders. While dysregulation of emotion may confer risk for the development of anxiety disorders, it remains unclear if there are differences in the extent to which fear and disgust can be effectively regulated. To fill this important gap in the literature, unselected participants (N?=?95) experienced fear or disgust via video exposure, and they were instructed to employ either reappraisal or suppression to regulate their emotional experience while viewing the videos. For those exposed to fear-relevant content, change in emotional distress did not significantly differ between those that suppressed and those that reappraised. However, significantly less emotional distress was observed for those that reappraised compared to those that suppressed when exposed to disgust-relevant content. Although physiological arousal varied over time as a function of the emotional content of the videos, it did not vary as a function of emotion regulation strategy employed. These findings suggest that reappraisal may be especially effective in regulating verbal distress when exposed to disgusting cues in the environment. The implications of these findings for the treatment of anxiety disorders that are characterised by excessive disgust reactions will be discussed.     

提取-消退范式中复合刺激对恐惧消退的影响

情绪障碍治疗的关键在于消退条件性恐惧记忆,研究证明基于记忆再巩固的提取-消退范式能有效消除或改写原有的恐惧记忆。本研究将提取-消退范式应用到更复杂的恐惧记忆中,采用多感官复合刺激(声音+图片)作为条件刺激,以皮电反应作为恐惧反应指标,考察采用单个线索(声音或图片)、复合线索(声音+图片)进行提取-消退对条件性恐惧记忆的消退效果有何差异。结果表明:声音线索提取-消退组出现了自发恢复和重建效应,图片提取-消退组只出现了重建效应,复合刺激提取-消退组未出现自发恢复和重建效应。说明由复合刺激线索引发的条件性恐惧,采用复合刺激中的单个较强线索或原有完整线索进行提取-消退,对恐惧记忆的消退效果最好。     

心理辅导室的建立与小儿外科

手术是小儿外科的主要治疗手段,又是一个创伤过程,同时也是一个心理应激过程,对于患儿来说这种应激会使其产生恐惧心理。同时小儿外科工作具有双重性,不仅要为患儿服务同时还需满足家长不同层次的心理需求。所以有必要在小儿外科科室内建立一个系统的心理辅导机构即心理辅导室来做好家长及患儿的心理疏导。     

Facilitation of Extinction of Conditioned Fear by D-Cycloserine

Abstract— Excessive fear and anxiety are characteristic of disorders such as post-traumatic stress disorder (PTSD) and phobias and are believed to reflect abnormalities in neural systems governing the development and reduction of conditioned fear. Conditioned fear can be suppressed through a process known as extinction, in which repeated exposure to a feared stimulus in the absence of an aversive event leads to a gradual reduction in the fear response to that stimulus. Like conditioned fear learning, extinction is dependent on a particular protein (the N-methyl-D-aspartate or NMDA receptor) in a part of the brain called the amygdala. Blockade of this receptor blocks extinction and improving the activity of this receptor with a drug called D-cycloserine speeds up extinction in rats. Because exposure-based psychotherapy for fear disorders in humans resembles extinction in several respects, we investigated whether D-cycloserine might facilitate the loss of fear in human patients. Consistent with findings from the animal laboratory, patients receiving D-cycloserine benefited more from exposure-based psychotherapy than did placebo-treated controls. Although very preliminary, these data provide initial support for the use of cognitive enhancers in psychotherapy and demonstrate that preclinical studies in rodents can have direct benefits to humans.     

大学生社会排斥对社交焦虑的影响：负面评价恐惧与人际信任的作用

为探讨大学生社会排斥对社交焦虑的影响以及负面评价恐惧和人际信任在二者之间的作用机制,研究采用大学生社会排斥问卷（SEQU）、社交焦虑量表（SASSCS）、负面评价恐惧量表（BFNES）及人际信任量表（ITS）对450名大学生进行测试。结果表明：（1）大学生社会排斥不仅对个体的社交焦虑水平产生影响,还会通过负面评价恐惧的中介作用对社交焦虑产生影响;（2）人际信任能够调节大学生社会排斥对社交焦虑的直接作用,具体而言,与高人际信任的大学生相比较,较低人际信任的大学生的社会排斥对社交焦虑的预测作用更加显著。
