惊恐障碍的认知偏向研究

文章综述了惊恐障碍患者对威胁性信息的注意偏向、解释偏向、记忆偏向等认知偏向。对威胁性信息的优先注意激发焦虑体验,对模糊信息的灾难化解释增加焦虑水平,对引起焦虑感信息的记忆保持促使惊恐体验更易于提取,这3种认知偏向促使具有焦虑倾向的个体对惊恐障碍更易感,也是惊恐障碍形成和保持的关键因素     

Associations Among Selective Attention, Memory Bias, Cognitive Errors and Symptoms of Anxiety in Youth

The purpose of this study was to examine the linkages among selective attention, memory bias, cognitive errors, and anxiety problems by testing a model of the interrelations among these cognitive variables and childhood anxiety disorder symptoms. A community sample of 81 youth (38 females and 43 males) aged 9-17 years and their parents completed measures of the child's anxiety disorder symptoms. Youth completed assessments measuring selective attention, memory bias, and cognitive errors. Results indicated that selective attention, memory bias, and cognitive errors were each correlated with childhood anxiety problems and provide support for a cognitive model of anxiety which posits that these three biases are associated with childhood anxiety problems. Only limited support for significant interrelations among selective attention, memory bias, and cognitive errors was found. Finally, results point towards an effective strategy for moving the assessment of selective attention to younger and community samples of youth.

Luck Attributions and Cognitive Bias

Philosophers have developed three theories of luck: the probability theory, the modal theory, and the control theory. To help assess these theories, we conducted an empirical investigation of luck attributions. We created eight putative luck scenarios and framed each in either a positive or a negative light. Furthermore, we placed the critical luck event at the beginning, middle, or end of the scenario to see if the location of the event influenced luck attributions. We found that attributions of luckiness were significantly influenced by the framing of the scenario and by the location of the critical event. Positively framing an event led to significantly higher lucky ratings than negatively framing the same exact event. And the closer a negative event was placed toward the end of a scenario, the more unlucky the event was rated. Overall, our results raise the possibility that there is no such thing as luck and thereby pose serious challenges to the three prominent theories of luck. We instead propose that luck may be a cognitive illusion, a mere narrative device used to frame stories of success or failure.     

乐观偏差的认知神经机制

乐观偏差是指人们趋向于认为好事发生在自己身上, 坏事发生在他人身上的一种心理期望(Weinstein, 1980)。乐观偏差的研究范式主要有社会比较范式、过去未来想象范式以及信息转变任务范式。运用fMRI对乐观偏差研究发现, 乐观偏差的神经机制主要涉及前喙扣带皮质和杏仁核、前额叶、多巴胺等。未来要结合社会比较和信息转变范式对乐观偏差进行测量; 研究乐观偏差认知机制的神经机制, 特别是采用ERP技术研究乐观偏差的认知机制; 同时要进一步揭示不同亚型乐观偏差的神经机制; 最后还要开展乐观偏差影响心理健康的神经机制研究。     

抑郁症人群的心境一致性认知偏向

心境一致性认知偏向指的是抑郁病人的认知加工偏向负性情绪效价, 简称认知偏向。大量行为学、电生理学以及脑成像学的研究显示该认知偏向主要包括知觉偏向、注意偏向、记忆偏向以及解释偏向。该认知偏向以加工偏向负性、积极偏向缺失以及认知控制受损为特点, 且是杏仁核等边缘系统对负性信息过度激活、纹状体对正性信息激活不足以及额区激活模式异常三个相应脑机制协同作用的产物。目前此领域存在各认知偏向之间联系不清楚、认知偏向和抑郁症的因果关系难以确定以及各研究结果不一致等有待回答的问题, 这些重要问题值得引起该领域未来研究者的注意。     

焦虑障碍的认知偏向矫正：应用与争议

认知偏向是焦虑障碍患者的重要认知特征, 是指患者或高焦虑个体对负性或威胁性信息存在认知加工方面的偏向。目前该领域的研究聚焦于注意偏向和解释偏向。近年来, 研究者致力于将认知偏向的矫正应用于焦虑障碍患者的临床治疗, 得到了不一致的结果。本文总结了将认知偏向矫正应用于临床实践的不同方式, 并从主观报告的疗效证据、行为及生理指标的疗效证据, 以及未发现疗效证据的研究三方面回顾了近年来的研究成果。对于结果的高度不一致, 本文从期望效应、干预对象、因变量和其它参数等方面探讨了可能的原因, 并讨论了未来可能的研究方向。     

Let It Go: Positive Affect Attenuates Sunk Cost Bias by Enhancing Cognitive Flexibility

Sunk cost bias is a pervasive problem in consumer decision making. It occurs when people continue to invest resources toward unsuccessful outcomes merely because they previously invested in them. This tendency exists because people devote too much attention to prior investments without considering how other factors may impact their decision outcome. While many suggested interventions to attenuate sunk cost bias involve altering cognitive processes, we examine an alternate affective route. Specifically, we propose that inducing positive affect attenuates sunk cost bias by naturally facilitating flexible thought processes. Across four studies, using hypothetical and real decision tasks, we find that positive affect induced in three different ways consistently attenuates sunk cost bias involving money, time, and effort investments. Further, we demonstrate that this occurs because people experiencing positive affect have enhanced cognitive flexibility. They consider more relevant decision factors and perceive sunk cost as having less of an influence on their decision outcomes. Then, in a fifth study, we show that a thought intervention promoting flexibility can attenuate consumers’ suboptimal commitment tendency in a field setting.     

A Single-Session Online Cognitive Bias Modification of Interpretations Modified for Adults With Anxiety and Depressive Symptoms

Anxiety and depression are common, co-occurring, and costly mental health disorders. Cognitive bias modification aims to modify biases to reduce associated symptoms. Few studies have targeted multiple biases associated with both anxiety and depression, and those that have lacked a control condition. This study piloted a single-session online cognitive bias modification (known as CBM-IA) designed to target two biases associated with anxiety and depression—interpretation bias and attribution style—in adults with varying levels of anxiety and depressive symptoms. Participants (18–26 years) with at least mild levels of anxiety/stress and depressive symptoms on the DASS-21 were randomly allocated to an intervention (n = 23) or a control (n = 22) condition. The training consisted of a single-session online CBM-IA to encourage positive interpretations and a positive attribution style.Interpretation bias, attribution style, anxious and depressive mood states, and anxiety, stress and depressive symptoms improved at posttraining and at follow-up, irrespective of condition. Changes in interpretation bias from pre- to posttraining were significantly associated with changes in anxious mood state. CBM-IA, as implemented in this single-session pilot study, did not significantly reduce targeted biases and symptoms compared to a control condition. This adds to the mixed evidence on the efficacy of single-session CBM-I for altering biases and symptoms.     

Stability of Cognitive Bias for Threat Cues in Phobia

The present study examined whether the cognitive bias for threat is a stable phenomenon in spider phobics and not in nonphobic controls. The rationale of this study was that the use of emotional bias for individual assessment in clinical practice requires stability of this phenomenon. In order to assess the stability of the emotional bias, the spider Stroop task was administered twice to spider phobics and controls, with a time lag of 3 weeks. In two experiments, spider phobics (n_{exp. 1} = 20; n_{exp. 2} = 33) and controls (n_{exp. 1} = 24; n_{exp. 2} = 25) were selected on basis of a structured interview. In the second experiment, subjects anticipated exposure to a real-life spider. Emotional bias was inferred from color-naming latencies on spider words versus control words. In line with our prediction, the bias for threat was stable in spider phobic individuals but not in controls. This stability could not be attributed to a general cognitive characteristic because a standard Stroop task did not differentiate between the spider phobics and the controls. The results support the view that cognitive processing of threat in anxiety is stable. It is proposed to use both the emotional bias and its stability as measures of the constraints on the flexibility of the cognitive fear-network.     

Cognitive Bias for the Distribution of Ball Landing Positions in Amateur Tennis Players (Cognitive Bias for the Motor Variance in Tennis)

This study aimed to investigate whether the isotropy bias (estimating one's own motor variance as an approximately circular distribution rather than a vertically elongated distribution) arises in tennis players for the estimation of the two-dimensional variance for forehand strokes in tennis (Experiment 1), as well as the process underlying the isotropy bias (Experiment 2). In Experiment 1, 31 tennis players were asked to estimate prospectively their distribution of ball landing positions. They were then instructed to hit 50 forehand strokes. We compared the eccentricity of the ellipse calculated from estimated and observed landing positions. Eccentricity was significantly smaller in the estimated ellipse than in the observed ellipse. We assumed that the isotropy bias for the estimated ellipse comes from the process of variance estimation. In Experiment 2, nine participants estimated the 95% confidence interval of 300 dots. Eccentricity was significantly smaller in their estimated ellipses than it was in the ellipses for the dots, though the magnitude of bias decreased for the estimation of dots. These results suggest that the isotropy bias in tennis ball landing position includes the bias of recognizing landing position and the bias of estimating the ellipse confidence interval from the recognized landing position.     

Cognitive Bias for Pictorial and Linguistic Threat Cues in Children

The present study was designed to test the conditions under which threat-related cognitive bias can be observed in anxious children. Measures of cognitive bias for threatening words and pictures were obtained from spider fearful children (N = 55) and non-fearful children (N = 58) aged 8–11 in the first experiment, and from spider fearful children (N = 44), and two control groups (N = 41; N = 36) aged 8 in the second experiment. Cognitive bias was assessed by the emotional Stroop task. In line with our previous findings, all children aged 8 showed a bias for spider words, but not for spider pictures. However, a relation between spider fear and bias was observed when age was taken into account: bias for spider words decreased with age in the non-fearful children whereas this bias maintained in the fearful group. This differential age effect too replicated earlier findings (Kindt, Bierman, & Brosschot, 1997). It is suggested that a bias for threat words is a normal characteristic in children aged 8. During development, normal children learn to inhibit this processing bias, whilst fearful children fail to learn this ability.     

Attachment Relationships as Predictors of Cognitive Interpretation and Response Bias in Late Adolescence

We investigated behavioural and cognitive representations of attachment style. Specifically, we sought to test continuity in attachment style and whether participants' perceptions of their attachments to parents, peers, and romantic partners would predict cognitive interpretation and responses to 12 ambiguous situation scenarios. Participants were 161 undergraduate students (17–20 years) who completed the Parental Bonding Instrument, the Attachment Style Questionnaire and the Inventory of Parent and Peer Attachment (peer subscale). Participants then indicated whether they interpreted ambiguous situations as threatening versus non-threatening and how they would respond (proactively, aggressively, or avoidantly). Regression analyses revealed that insecure parental attachments were the main predictor of participants' interpretations and their planned responses, followed by romantic attachments. Peer attachments played little role in the predictions. These results suggest that interpretation of situations and subsequent plans of action may be influenced by attachment related experiences. We discuss our findings in terms of their relevance to attachment theory and their application to our understanding of the concepts of attachment in development of interpersonal relationships.     

幼儿语言发展中的形状偏好现象及其认知机制

形状偏好是指儿童语言发展过程中倾向于认为相同形状的物体拥有相同名称的现象。已有研究采用词汇拓展、分类和归纳推理等任务发现, 2~3岁甚至更早的幼儿就已经表现出形状偏好, 且表现受刺激物的属性、创造者的意图和功能及因果/比较关系等因素影响。然而, 形状偏好现象存在着联结观和概念观两种不同的解释。未来的研究应该采用认知神经科学的方法, 并结合发展中的其它问题, 从特殊被试和跨文化的角度来探讨这一现象的神经机制。     

男性对女性面孔吸引力的认知偏好: 来自ERP的证据

运用事件相关电位(ERPs)技术, 采用学习-再认实验任务, 探讨了男性对有、无吸引力女性面孔图片进行判断和再认时脑内时程的动态变化。行为数据结果表明, 男性对有吸引力女性面孔的反应时更长, 再认正确率更高。ERP结果发现, 有、无吸引力面孔诱发的ERP早成分和晚成分都存在显著差异, 最强效应出现在大脑皮层的中前部。在判断任务和再认任务中, 有吸引力的女性面孔都比无吸引力的女性面孔诱发出更大的ERP成分(分别为N300、P350~550ms和P160、N300~500ms、P500~700ms)。结果表明, 男性对有吸引力的女性面孔的判断和再认存在偏好。     

Maintaining Life Satisfaction: The Role of Positive Cognitive Bias

Recent research into population standards of life satisfaction has revealed a remarkable level of uniformity, with the mean values for Western populations clustering at around three-quarters of the measurement scale maximum. While this seems to suggest the presence of a homeostatic mechanism for life satisfaction, the character of such a hypothetical device is uncertain. This paper proposes that well-being homeostasis is controlled by positive cognitive biases pertaining to the self. Most particular in this regard are the positive biases in relation to self-esteem, control and optimism. Past controversies in relation to this proposition are reviewed and resolved in favour of the proposed mechanism. The empirical data to support this hypothesis are discussed in the context of perceived well-being as an adaptive human attribute.     

攻击者的注意偏向与归因偏向及其关系

在攻击者的认知偏向中,注意偏向与归因偏向尤为引人注目。攻击者常偏向于注意敌意性的刺激,并会对模棱两可的情境作出敌意性的解释。二者的关系存在注意优先模型与解释优先模型两种可能性,注意优先模型认为注意过程先于解释过程,解释优先模型则相反。两种假设各有论据支持,而攻击者注意偏向与归因偏向的关系尚无定论。今后的研究当改进实验方法、运用多种技术从理论和应用两方面更深入地探讨攻击者的这二种偏向及其关系。     

超重女性对食物信息加工的注意偏向和记忆偏向

采用与食物图片相关的点探测任务和学习—再认范式考察超重女性对不同热量食物信息的注意偏向和记忆偏向。结果发现：(1) 超重女性对高热量食物信息存在注意警觉—注意脱离困难模式,对低热量食物信息仅表现为注意回避模式。(2) 超重组女性对高热量食物信息的再认正确率显著高于正常体重组,而对低热量食物信息的再认成绩组间差异不显著。研究结果证实了超重女性对高热量食物信息投入更多的认知资源,存在注意偏向和记忆偏向。     

Cognitive Bias in Spider-Phobic Children: Comparison of a Pictorial and a Linguistic Spider Stroop

The relation between spider fear in children and cognitive processing bias toward threatening information was examined. It was investigated whether spider fear in children is related to a cognitive bias for threatening pictures and words. Pictorial and linguistic Stroop stimuli were administered to 28 spider phobic and 30 control children aged 8–12. Spider-phobic children showed a moderate bias for threatening words. Surprisingly, no bias was found for spider pictures, while the spider-phobic children judged the pictures as more aversive. Moreover, in a recent similar study in adults (Kindt & Brosschot, 1997), a strong relation between spider phobia and bias toward threat words and pictures was found. Several explanations are given to account for this divergence.
