高功能自闭症个体对威胁性情绪面孔的注意偏向

高功能自闭症(High-Functioning Autism, HFA)个体智力正常, 但也面临着严重的社会功能障碍。对威胁性情绪面孔的注意偏向与HFA个体社会功能的发展密切相关。梳理相关研究发现, HFA个体在自动加工阶段和情绪目标参与阶段, 不存在威胁性情绪面孔注意偏向; 而在任务与情绪无关的控制加工阶段, 存在威胁性情绪面孔注意偏向。针对HFA个体威胁性情绪面孔注意偏向的理论解释主要有杏仁核理论、强烈世界理论和执行功能理论等。神经生理机制方面, HFA个体对威胁性情绪面孔的注意偏向可能与其异常的皮下及皮层通路功能有关, 同时可能会受5-羟色胺系统基因及催产素水平等的影响。未来研究可在综合考虑研究方法及个体因素的基础上, 进一步探究其加工特征及神经生物机制, 着力开发科学有效的干预策略。     

不安全依恋者注意偏向的形成机制及神经基础

不安全依恋者的注意偏向是指依恋焦虑和回避个体对依恋信息产生或趋近或回避的注意偏好, 这一注意偏好使得个体形成了处理与依恋对象关系的特殊认知机制：依恋回避个体偏好采用防御性机制, 倾向于回避对依恋信息的注意; 依恋焦虑个体偏好采用夸大性机制, 倾向于夸大威胁性信息, 因而会积极寻求与依恋对象的亲近。不安全依恋者注意偏向的差异主要体现在情绪信息、痛觉感受和工作记忆三个方面; 加工阶段特征主要涉及P1、N1波等代表的注意自动加工和LPP波代表的注意控制加工; 脑网络上主要包括两个子网络, 即负责情绪评估的边缘系统和负责情绪调节的以前额叶为代表的神经网络。未来研究中更应该关注刺激物的生态效度, 检验依恋系统是否激活, 不安全依恋者注意偏向的自动加工和控制加工阶段的关系, 不安全依恋者注意偏向产生的分子遗传机制以及注意偏向的跨文化研究。     

积极情绪反馈对注意捕获影响的实验研究

目的：研究采用“学习-测试”范式,通过3个实验探讨积极社会情绪反馈对注意捕获的影响。方法：实验1,在学习阶段做出反应后,分别给予积极情绪和中性情绪反馈,探讨积极情绪和中性情绪捕获注意的情况;实验2,学习阶段做出反应后,没有任何情绪反馈;实验3,改变学习阶段积极情绪和中性情绪反馈图片出现的频率,探讨图片出现频率对注意捕获的影响。结果：（1）与中性情绪相比,积极情绪捕获了较多注意（实验1）;（2）无情绪反馈时,经过多次练习的刺激作为干扰刺激也捕获到了注意（实验2）;（3）积极情绪影响刺激注意优先性的过程还受到积极情绪图片出现频率的影响（实验3）。结论：积极情绪捕获注意的机制中,也有自上而下目标驱动的机制在起作用;情绪图片出现的频率也会影响社社会情绪对注意的捕获。     

情绪信息的多通道整合

自然环境中人类情绪信息的交流是依靠多个感觉通道实现的,多通道整合是情绪加工的基础。近年来的行为学、电生理学与神经成像的研究表明,情绪信息的加工具有跨通道自动整合的特点,它发生在认知加工的早期阶段,与颞上回、颞中回、海马旁回和丘脑等脑区密切相关。不同情绪的整合既有共同的神经基础,又有各自独特的加工区域。情绪信息的整合机制还可能与加工类型及注意资源有关。在未来研究中,实验的标准化、动态化、自然化有助于提高研究的准确性和研究间的可比性,而对特殊群体的研究,以及综合研究情绪加工与注意等其他认知过程则有助于我们进一步探索多通道整合的神经机制。     

情绪加工老龄化机制：表情的自动加工和控制加工视角

情绪加工老龄化已经成为老龄化研究的新热点, 但其内在机制仍然缺乏统一的解释。本研究以自动加工和控制加工为切入点, 综合行为实验、ERP和fMRI实验技术, 开展表情加工的老龄化研究, 从情绪与认知交互的角度进一步揭示情绪加工老龄化的内在机制。具体内容包括表情自动加工和控制加工的年龄差异及其神经机制, 表情自动加工与认知控制的相互作用, 以及个体差异在情绪加工老龄化中的作用等。本研究将加深对情绪加工老龄化的理解, 为相关理论模型的验证、修正和完善提供实证依据。     

与任务无关的刺激-反应联结对中老年人自动加工的影响

采用掩蔽启动范式,选取字母和数字作为刺激,任务因素为与当前任务无关的处于预备状态的刺激-反应联结,探讨自上而下的任务因素对中老年人自动加工过程的影响。发现中老年被试的自动反应激活过程不受到自上而下的当前无关的、处于预备状态的刺激-反应联结作用的影响,自动加工是完全自动化的。     

冲突图式对情绪的人际效应的调节

人际冲突中情绪人际效应通过情感反应和推断加工影响着人际冲突中的个体行为。这一效应受到了人际冲突图式的调节。人际冲突图式对于情绪人际效应的调节作用主要表现在两方面:1)冲突图式通过调节注意资源影响对于情绪的推断加工;2)冲突图式通过影响个体的认知动机和对情境的互依性知觉影响着情感反应、推断加工的相对力量。今后需要全面考察各种符合现实生活的情绪人际效应,同时加强本土化研究,进而建构更具解释力的整合模型。     

左侧眶额皮层在自动情绪调节下注意选择中的作用：来自经颅直流电刺激的证据

前人研究表明自动情绪调节能够自上而下地影响情绪及情绪性注意过程。近来有研究提示自动情绪调节与眶额皮层(orbitofrontal cortex, OFC)有关。也有研究表明左侧OFC的激活影响负性注意偏向。本研究采用经颅直流电刺激技术, 考察阈下启动情绪控制目标条件下, 抑制左侧眶额皮层兴奋性是否影响负性注意偏向。结果发现, 使用阴极刺激抑制左侧OFC活动可以加快被试对与恐惧刺激位置一致的探测点的反应。该结果提示左侧眶额皮层是自动情绪调节下情绪性注意选择相关的重要脑区。     

心理复原的机制：来自特质性复原力个体的证据

心理复原(力)是指个体在经历对生命具有威胁的事件或严重的创伤后仍然能回复到良好适应状况的心理发展现象。基于能力取向的文献表明, 积极情绪性、情绪调节是特质性复原力机制研究的重要内容; 脑岛和前额叶(特别是vmPFC和OFC)是其敏感的脑区; 作用于杏仁核脑区的5-羟色胺转运蛋白与特质性复原力密切相关。基于这些研究结果, 提出积极情绪与(自动、有意)情绪调节交互作用的双重加工理论和根据实际需要调节情绪的情绪灵活性理论。未来的研究应该就情绪记忆、人格特质等在心理复原中的作用进行探讨。     

自动情绪调节：基于社会文化与神经科学的考量

情绪调节的以往研究大多聚焦于有意情绪调节,而日常生活中普遍存在的自动情绪调节却较少受到关注。与自动加工类似,自动情绪调节无需意识努力、注意分配及有意控制,使个体在阈下知觉中自动有效地调节情绪,根据发生在情绪反应产生之前或之后分为先行聚焦自动情绪调节和反应聚焦自动情绪调节,前者会产生相对适应良性后果,后者则会产生相对适应不良后果,来自神经科学的证据显示两者存在不同的神经基础,这与社会文化考量相一致。社会文化对塑造自动情绪调节起着重要作用,情绪调节的自动认知加工在不断重复的社会文化实践和规范中内化而成。     

Automatic Emotion Regulation

How do people effectively regulate their emotional reactions? Why are some people better at this than others? Most prior research has addressed these questions by focusing on deliberate forms of emotion regulation. We argue that this focus has left out an important aspect of emotion regulation, namely, automatic emotion regulation (AER). Our review of the behavioral literature suggests that AER is pervasive in everyday life, and has far‐reaching consequences for individuals’ emotions. However, the behavioral literature has yet to address the mechanisms underlying the observed effects. Because it is difficult to directly measure the processes involved in AER, evidence from neuroscientific studies is particularly helpful in addressing these questions. Our review of the neuroscientific literature suggests distinct neural bases for different types of AER, which provides important clues about the cognitive and behavioral processes that might be involved in AER.     

情绪如何引发暴力犯的攻击?基于情绪调节理论的解释

本文基于情绪调节理论, 以暴力犯为被试, 通过2项研究探究了情绪在攻击产生过程中的作用。研究1采用改编的反应时竞争范式测量个体攻击行为。结果发现, 情绪调节动机在负性情绪与攻击间起完全中介作用, 证实了负面情绪状态下, 暴力犯会为了调节情绪而实施攻击。研究2进一步表明, 攻击的确能起到调节情绪的作用。具体来说, 在暴力犯群体中, 实施反应性攻击之后, 会伴随着正性情绪的提升和负性情绪的下降; 实施主动性攻击之后, 个体的正性情绪和负性情绪都会提升。文章从对攻击结果的预期和攻击的实际效果两个角度, 对攻击的情绪调节理论进行了验证, 为情绪在攻击产生过程中的作用提出了新的解释。今后的研究和实践过程中, 应设法避免个体通过攻击调节情绪, 引导其使用合理的方式调节情绪以减少攻击行为的产生。     

Emotion Beliefs,Emotion Regulation,and Emotional Experiences in Daily Life

One potential factor that could influence how individuals with at least moderate symptoms of depression cope with upsetting events in their daily lives is the beliefs that these individuals hold about whether emotions are malleable or fixed. The current study adopted an experience sampling approach to examine how the beliefs about emotion’s malleability related to daily positive and negative affect and daily emotion regulation efforts among individuals with at least moderate symptoms of depression (N = 84). Results demonstrated that individuals having at least moderate symptoms of depression who held more malleable beliefs about emotions reported decreased negative affect both overall during the day and specifically in response to daily upsetting events. Additionally, these individuals who held more malleable beliefs about their emotions also reported more daily use of cognitive reappraisal to regulate their emotions in response to upsetting daily events. Results from the current study extend previous work examining the relationship between emotion malleability beliefs, emotional experiences, and emotion regulation to examine these relationships in people who are moderately depressed as they navigate the emotional landscape of their daily lives.     

Don't Get Too Excited: Assessing Individual Differences in the Down-Regulation of Positive Emotions

A voluminous literature has documented the importance of emotion regulation for health and well-being. The studies in this literature, however, have generally focused on the down-regulation of negative affect. Few studies have examined the down-regulation of positive affect. In Study 1, we constructed a scale, the revised Regulatory Emotional Self-Efficacy Scale (r–RESE), which assesses both the down- and up-regulation of positive affect, in addition to the traditional down-regulation of negative affect. In Study 2, we conducted an extensive validation of the r–RESE scale, using a multimethod approach with informant ratings, to illustrate that the down-regulation of positive affect represents a process independent of each of the other forms of emotion regulation. In Study 3, we provided evidence that the ability to down-regulate positive emotions provides added predictive utility when predicting indexes of impulsivity and adjustment. Across the studies, we illustrate the potential importance of the down-regulation of positive emotions as a topic of study for the field of emotion regulation.     

自动情绪调节对负性情绪面孔注意偏向的影响

本研究通过成语匹配任务启动情绪调节目标,在情绪flanker任务中考察了自动情绪调节启动对注意偏向的影响。结果表明,中性启动条件下,被试表现出对负性情绪面孔的注意偏向,而情绪调节启动条件下,被试对正性、负性情绪面孔的注意分配不存在显著差异。这一结果说明自动情绪调节可以有效地减弱被试的负性情绪面孔注意偏向。

Automatic emotion regulation during anger provocation

Individuals frequently have to regulate their emotions, especially negative ones, to function successfully. However, deliberate emotion regulation can have significant costs for the individual. Are there less costly ways to achieve emotion regulatory goals? In two studies, we test the hypothesis that more automatic types of emotion regulation might provide the benefits of deliberate emotion regulation without the costs. Study 1 introduces a priming technique that manipulates automatic emotion regulation. Using this priming technique, we show that relative to priming emotion expression, priming emotion control leads to less anger experience in response to a laboratory anger provocation. Study 2 examines the experiential and physiological consequences of automatic emotion regulation. Results suggest that relative to priming emotion expression, priming emotion control reduces negative emotion experience without maladaptive cardiovascular responding. Together, these findings suggest that automatic emotion regulation may provide an effective means of controlling powerful negative emotions.     

Emotion processing and regulation in women with morbid obesity who apply for bariatric surgery

Emotional eating, the tendency to eat when experiencing negative affect, is prevalent in morbid obesity and may indicate that ways to deal with emotions are disturbed. Our aim was to compare emotion processing and regulation between 102 women with morbid obesity who apply for bariatric surgery and 102 women from the general population (control group) and to examine in the group with morbid obesity the association of emotion processing and regulation with emotional eating. The group with morbid obesity reported higher scores on difficulty identifying feelings (alexithymia, p?=?0.002) and suppression of emotions (p?=?0.003) than the control group. In the women with morbid obesity, more negative affect and a higher difficulty identifying feelings were correlated with more emotional eating (r?=?0.36 and r?=?0.35, p?相似文献   

Affective regulation in trichotillomania: Evidence from a large-scale internet survey

Trichotillomania (TTM), a repetitive hair-pulling disorder, is underrepresented in the clinical literature. The current project explores the relationship between affective regulation and disordered hair-pulling. Previous research suggests that cycles of emotional states are correlated with the disorder and may induce, reinforce, or otherwise contribute to hair-pulling behavior. We use anonymous internet survey responses from 1162 self-identified hair-pullers to address four questions about affective regulation in people with TTM: (1) Do hair-pullers experience greater difficulty “snapping out” of affective states than non-pullers? (2) Does difficulty with emotional control correlate with TTM severity? (3) Are subtypes identifiable based on the emotions that trigger hair-pulling behavior? (4) Does difficulty “snapping out” of an emotion predict whether that emotion triggers pulling behavior? The results showed a small-to-moderate relationship between affective regulation and problematic hair-pulling. In addition, individual patterns of emotion regulation were systematically related to emotional cues for hair-pulling as well as overall hair-pulling severity. These findings contribute to an understanding of the phenomenology of TTM and provide empirical support for treatments focused on affect regulation.
