Emotion processing

情感处理
  • 文章类型: Journal Article
    写作是人类最深刻的发明之一,促进大量信息的有效共享和传输。类似于图像和面部表情,视觉(书面)单词具有唤起情感内涵的能力。理解大脑如何感知这些用高度象征性的视觉词汇编码的情感细微差别是“情感神经语言学”新兴领域的一个重点。“这项调查的核心在于对早期后验负(EPN)的检查,事件相关电位(ERPs)成分在枕颞叶头皮区域刺激开始后约300ms达到峰值。EPN一直在回应情绪刺激,包括图片,面孔,视觉词。然而,先前的研究明显缺乏对EPN对汉语情感词的反应的观察,提出了关于汉语和其他语言之间情感处理的潜在差异的问题。鉴于汉语书写系统的语标性质和复合词在汉语词典中的普遍性,本研究旨在探讨汉语单态和复合词的情绪处理是否会引发EPN反应。进行了两个实验:实验1使用单字符单词(单形单词),而实验2使用了两个字符的单词(复合词)。参与者被分配了一个去/不去的任务,指示对未知单词(单词识别任务)或蓝色刺激(颜色决定任务)做出反应。使用数据驱动的质量单变量方法进行的数据分析显示,情感词和中性词之间的ERP差异显着。值得注意的是,时间进程,头皮地形图,在两个实验中,差异ERP的皮层发生器都表现出特征性的EPN响应。这些发现强烈支持了这样一种观点,即EPN反映了汉语单态和复合词中情感内涵的加工,为将来使用EPN作为与情感相关的ERP组件来调查汉语单词的情感处理奠定基础。
    Writing stands as one of humanity\'s most profound inventions, facilitating the efficient sharing and transmission of vast amounts of information. Similar to images and facial expressions, visual (written) words possess the ability to evoke emotional connotations. Understanding how the brain perceives these emotional nuances encoded in highly symbolic visual words is a key focus of the emerging field of \"affective neurolinguistics.\" At the core of this inquiry lies the examination of the early posterior negativity (EPN), an event-related potentials (ERPs) component peaking around 300 ms after stimulus onset in the occipitotemporal scalp region. EPN has consistently emerged in response to emotional stimuli, encompassing pictures, faces, and visual words. However, prior research has notably lacked observation of EPN in response to Chinese emotional words, raising questions about potential differences in emotional processing between Chinese and other languages. Given the logographic nature of the Chinese writing system and the prevalence of compound words in the Chinese lexicon, this study aims to explore whether the emotional processing of Chinese monomorphic and compound words elicits an EPN response. Two experiments were conducted: Experiment 1 utilized one-character words (monomorphic words), while Experiment 2 employed two-character words (compound words). Participants were assigned a go/no-go task, instructed to respond to unknown words (word recognition task) or blue stimuli (color decision task). Data analysis using a data-driven mass univariate approach revealed significant ERP differences between emotional and neutral words. Notably, the time course, scalp topography, and cortical generators of the difference ERP presented a characteristic EPN response in both experiments. These findings strongly support the notion that the processing of emotional connotations in both Chinese monomorphic and compound words is reflected by the EPN, paving the way for future research using EPN as an emotion-related ERP component for investigating emotional processing of Chinese words.

    目的:临床上焦虑的年轻人对情绪刺激过度警惕,难以将注意力从情绪刺激转移到非情绪刺激,提示认知控制对情绪的损害。然而,目前尚不清楚这种偏倚的神经底物是否在焦虑的临床与非临床范围内变化,还是因年龄而异.
    方法:7-17岁有临床焦虑(N=119)或没有焦虑诊断(N=41)的青少年在磁共振成像过程中与情绪面部干扰物匹配的情绪面部或匹配的形状,探测情绪处理和对情绪的认知控制,分别。从国家精神卫生研究所的研究领域标准框架构建,临床焦虑的年轻人被纳入诊断类别,在最小至亚临床严重程度范围内对未受临床影响的青少年进行采样.
    结果:在这两种情况下,与右下顶叶过度激活相关的焦虑严重程度,高度警惕的基质。大脑焦虑的关联也通过注意状态来区分;焦虑的严重程度与情绪处理(面部匹配)过程中左腹外侧前额叶皮层的更大激活以及在认知控制情绪(形状匹配)过程中左上颞沟和颞顶交界处的更大激活(以及较慢的反应)相关。年龄也调节了焦虑和对情绪的认知控制之间的关联,因此,对于年龄较小和平均年龄的儿童,焦虑与更大的右丘脑和双侧后扣带皮质激活相关,但不适合年长的年轻人。
    结论:大脑区域的异常功能与刺激驱动的对情绪分散者的注意力有关,可能会导致青少年焦虑。结果支持针对发育阶段量身定制的焦虑注意力调节干预措施的潜在效用。
    OBJECTIVE: Clinically anxious youth are hypervigilant to emotional stimuli and display difficulty shifting attention from emotional to nonemotional stimuli, suggesting impairments in cognitive control over emotion. However, it is unknown whether the neural substrates of such biases vary across the clinical-to-nonclinical range of anxiety or by age.
    METHODS: Youth aged 7 to 17 years with clinical anxiety (n = 119) or without an anxiety diagnosis (n = 41) matched emotional faces or matched shapes flanked by emotional face distractors during magnetic resonance imaging, probing emotion processing and cognitive control over emotion, respectively. Building from the National Institute of Mental Health Research Domain Criteria (RDoC) framework, clinically anxious youth were sampled across diagnostic categories, and non-clinically affected youth were sampled across minimal-to-subclinical severity.
    RESULTS: Across both conditions, anxiety severity was associated with hyperactivation in the right inferior parietal lobe, a substrate of hypervigilance. Brain-anxiety associations were also differentiated by attentional state; anxiety severity was associated with greater left ventrolateral prefrontal cortex activation during emotion processing (face matching) and greater activation in the left posterior superior temporal sulcus and temporoparietal junction (and slower responses) during cognitive control over emotion (shape matching). Age also moderated associations between anxiety and cognitive control over emotion, such that anxiety was associated with greater right thalamus and bilateral posterior cingulate cortex activation for children at younger and mean ages, but not for older youth.
    CONCLUSIONS: Aberrant function in brain regions implicated in stimulus-driven attention to emotional distractors may contribute to anxiety in youth. Results support the potential utility of attention modulation interventions for anxiety that are tailored to developmental stage.

    在情感的处理中,大脑准备和反应的独特的方式取决于负面或积极的细微差别的情绪激发。以前的调查表明,阴性诱导子通常比阳性和中性诱导子引起更强烈的神经活动,如事件相关电位(ERP)晚期后验阳性(LPP)复合体的所有子分量的振幅增加所反映的那样,而对厌恶情绪的了解较少。本研究旨在检查在厌恶刺激的处理过程中,LPP复合物是否比其他具有负或正效价的情绪激发者显示出更大的振幅,从而证实了它在早期或后期是厌恶相关的负偏性的神经标记。因此,在本研究中,我们在执行情感自我管理的视觉刺激任务期间利用ERP技术来解开与正面图像相关的神经贡献,负,厌恶,或中性情绪。至关重要的是,我们表明,在自我给药过程中,用厌恶激发子处理引起了最大的神经活动和最大的延迟。总的来说,与所有其他情绪相比,我们证明了与情绪激发者的不愉快和厌恶的特殊处理相关的进行性神经活动。
    In the processing of emotions, the brain prepares and reacts in distinctive manners depending upon the negative or positive nuance of the emotion elicitors. Previous investigations showed that negative elicitors generally evoke more intense neural activities than positive and neutral ones, as reflected in the augmented amplitude of all sub-components of the event-related potentials (ERP) late posterior positivity (LPP) complex, while less is known about the emotion of disgust. The present study aimed to examine whether the LPP complex during the processing of disgust stimuli showed greater amplitude than other emotion elicitors with negative or positive valences, thus confirming it as a neural marker of disgust-related negativity bias at earlier or later stages. Thus, in the present study, we leveraged the ERP technique during the execution of an affective self-administered visual stimuli task to disentangle the neural contributions associated with images of positive, negative, disgust, or neutral emotions. Crucially, we showed that handling with disgust elicitors prompted the greatest neural activity and the highest delay during self-administration. Overall, we demonstrated progressive neural activities associated with the unpleasantness of the emotion elicitors and peculiar processing for disgust compared with all other emotions.

    作为视听刺激的来源,电影让人们接触到各种各样的情绪。有趣的是,几种流派的特点是负面的情感内容。尽管存在理论方法,对特定电影类型的偏好和负面情绪的神经元处理知之甚少。
    我们调查了电影类型偏好与边缘和奖励相关的大脑反应性之间的关联,通过在257名健康参与者中采用具有负面情绪面孔的功能磁共振成像范式来缩小这一差距。我们比较了偏爱特定电影类型的个体和没有这种偏爱的个体之间杏仁核和伏隔核(NAcc)的功能活性。
    喜欢动作片的个体的杏仁核激活相对较高(pTFCE-FWE=0.013)。喜剧类型偏好与杏仁核(pTFCE-FWE=0.038)和NAcc活性(pTFCE-FWE=0.011)增加有关。相比之下,犯罪/惊悚片偏好(杏仁核:pTFCE-FWE≤0.010,NAcc:pTFCE-FWE=0.036),以及纪录片偏好,与杏仁核(pTFCE-FWE=0.012)和NAcc活性(pTFCE-FWE=0.015)降低有关。该研究揭示了参与者的体裁偏好与大脑对负面情感刺激的反应性之间的关联。有趣的是,对具有相似情感特征的流派的偏好(动作,犯罪/惊悚片)与相反方向的神经活动有关。讨论了大脑反应性与对不同电影相关满足的敏感性之间的潜在联系。
    UNASSIGNED: As a source of audio-visual stimulation, movies expose people to various emotions. Interestingly, several genres are characterized by negative emotional content. Albeit theoretical approaches exist, little is known about preferences for specific movie genres and the neuronal processing of negative emotions.
    UNASSIGNED: We investigated associations between movie genre preference and limbic and reward-related brain reactivity to close this gap by employing an fMRI paradigm with negative emotional faces in 257 healthy participants. We compared the functional activity of the amygdala and the nucleus accumbens (NAcc) between individuals with a preference for a particular movie genre and those without such preference.
    UNASSIGNED: Amygdala activation was relatively higher in individuals with action movie preference (p TFCE-FWE = 0.013). Comedy genre preference was associated with increased amygdala (p TFCE-FWE = 0.038) and NAcc activity (p TFCE-FWE = 0.011). In contrast, crime/thriller preference (amygdala: p TFCE-FWE ≤ 0.010, NAcc: p TFCE-FWE = 0.036), as well as documentary preference, was linked to the decreased amygdala (p TFCE-FWE = 0.012) and NAcc activity (p TFCE-FWE = 0.015). The study revealed associations between participants\' genre preferences and brain reactivity to negative affective stimuli. Interestingly, preferences for genres with similar emotion profiles (action, crime/thriller) were associated with oppositely directed neural activity. Potential links between brain reactivity and susceptibility to different movie-related gratifications are discussed.

    自闭症儿童的社会情绪功能受损,但是弱抑制控制是他们社会情感困难的基础吗?这项研究通过检查是否和,如果是,在学龄期自闭症和神经典型儿童中,抑制控制如何受到面部真实感和情绪效价的影响。52名自闭症患者和52名年龄在10-12岁之间的神经典型对照完成了真实和卡通情感面孔Go/Nogo任务,同时记录了事件相关电位(ERP)。抑制情绪成分的分析(即,N2,P3和LPP)和特定于面部的N170表明,自闭症儿童在抑制Nogo试验的同时引发了更大的N2,而对于真实但不是卡通的情感面孔,则产生了更大的P3/LPP和晚期LPP。此外,自闭症儿童只表现出减少的N170到真实的面部情绪。此外,相关结果表明,自闭症儿童的行为抑制和情绪识别能力较好与N170降低相关。这些发现表明,自闭症儿童抑制控制的神经机制效率较低,在真实面部加工过程中受到的干扰更大。这可能会影响他们适合年龄的社会情感发展。
    Impaired socioemotional functioning characterizes autistic children, but does weak inhibition control underlie their socioemotional difficulty? This study addressed this question by examining whether and, if so, how inhibition control is affected by face realism and emotional valence in school-age autistic and neurotypical children. Fifty-two autistic and 52 age-matched neurotypical controls aged 10-12 years completed real and cartoon emotional face Go/Nogo tasks while event-related potentials (ERPs) were recorded. The analyses of inhibition-emotion components (i.e., N2, P3, and LPP) and a face-specific N170 revealed that autistic children elicited greater N2 while inhibiting Nogo trials and greater P3/LPP and late LPP for real but not cartoon emotional faces. Moreover, autistic children exhibited a reduced N170 to real face emotions only. Furthermore, correlation results showed that better behavioral inhibition and emotion recognition in autistic children were associated with a reduced N170. These findings suggest that neural mechanisms of inhibitory control in autistic children are less efficient and more disrupted during real face processing, which may affect their age-appropriate socio-emotional development.

    分裂型,类似于精神分裂症症状的人格结构,通常与异常的面部情绪感知有关。基于精神病经历中普遍存在的威胁感,以及看到他人面部表情的直接感知历史,具有高分裂型特征的个体可能表现出更高的预期愤怒的倾向。为了测试这个,我们使用了来自代表性动量(RM)的见解,一种感知现象,其中动态事件的终点被系统地向前移位,在不久的将来。提出了愤怒到模棱两可和快乐到模棱两可的化身面孔,每个后跟一个与端点具有相同(模糊)表达式的探针,或者一个稍微改变以表达更大的幸福/愤怒。参与者判断探针是否与终点“相等”,并评估他们的信心。使用分裂型人格问卷(SPQ)将样本分为高(N=46)和低(N=49)分裂型性状。首先,在快乐到模棱两可的面孔中发现了一种前向偏见,仅针对动态面孔向潜在威胁(愤怒)的变化提出情感预期。这可能反映了一种适应性机制,因为它是更安全的预测任何敌意来自一个特定的比相反。其次,与我们的假设相反,高分裂型特征并没有提高快乐到模棱两可的面孔的RM,他们也没有导致对偏见判断的过度自信。这可能表明非临床分裂型中情绪预期的典型模式,但是由于使用了自我报告问卷,所以需要谨慎,大学生,和适度的样本量。未来的研究还应调查精神分裂症的临床表现是否相同。
    Schizotypy, a personality structure that resembles schizophrenia symptoms, is often associated with abnormal facial emotion perception. Based on the prevailing sense of threat in psychotic experiences, and the immediate perceptual history of seeing others\' facial expressions, individuals with high schizotypal traits may exhibit a heightened tendency to anticipate anger. To test this, we used insights from Representational Momentum (RM), a perceptual phenomenon in which the endpoint of a dynamic event is systematically displaced forward, into the immediate future. Angry-to-ambiguous and happy-to-ambiguous avatar faces were presented, each followed by a probe with the same (ambiguous) expression as the endpoint, or one slightly changed to express greater happiness/anger. Participants judged if the probe was \"equal\" to the endpoint and rated how confident they were. The sample was divided into high (N = 46) and low (N = 49) schizotypal traits using the Schizotypal Personality Questionnaire (SPQ). First, a forward bias was found in happy-to-ambiguous faces, suggesting emotional anticipation solely for dynamic faces changing towards a potential threat (anger). This may reflect an adaptative mechanism, as it is safer to anticipate any hostility from a conspecific than the opposite. Second, contrary to our hypothesis, high schizotypal traits did not heighten RM for happy-to-ambiguous faces, nor did they lead to overconfidence in biased judgements. This may suggest a typical pattern of emotional anticipation in non-clinical schizotypy, but caution is needed due to the use of self-report questionnaires, university students, and a modest sample size. Future studies should also investigate if the same holds for clinical manifestations of schizophrenia.

    本荟萃分析总结了边缘性人格障碍(BPD)中社会认知和情绪处理任务的大脑激活。我们进行了两项荟萃分析,以详细说明两种类型任务之间的共性和潜在差异。在第一次荟萃分析中,我们实施了更宽松的任务选择策略(包括社交和情感内容)。结果证实了先前报道的双侧杏仁核和前额叶皮质BPD患者的过度激活以及双侧下额回的过度激活。当应用更严格的方法来选择任务时,狭隘地关注社会认知任务,我们只在前额区发现了激活,特别是在前扣带回和腹内侧前额叶皮质。我们回顾了这些领域在健康成年人社会认知中的作用,表明观察到的BPD过度激活可能反映了社会认知中对自我相关思想的过度依赖。
    The present meta-analysis summarizes brain activation for social cognition and emotion-processing tasks in borderline personality disorder (BPD). We carried out two meta-analyses to elaborate on commonalities and potential differences between the two types of tasks. In the first meta-analysis, we implemented a more liberal strategy for task selection (including social and emotional content). The results confirmed previously reported hyperactivations in patients with BPD in the bilateral amygdala and prefrontal cortex and hypoactivations in bilateral inferior frontal gyri. When applying a stricter approach to task selection, focusing narrowly on social cognition tasks, we only found activation in prefrontal areas, particularly in the anterior cingulate and ventromedial prefrontal cortex. We review the role of these areas in social cognition in healthy adults, suggesting that the observed BPD hyperactivations may reflect an overreliance on self-related thought in social cognition.

    异常情绪处理是精神分裂症谱系障碍(SSD)的核心特征,包括多种操作。虽然一些领域的赤字已经得到了很好的表征,我们对通过语言发生的情绪处理异常了解较少,这与社会生活高度相关。这里,我们介绍了一种使用深度学习从口语中快速估计情感处理的新方法,在男性确定的SSD患者(n=37)和健康对照(n=51)中测试这种方法。利用对唤起刺激的自由反应,我们得出了适当性的衡量标准,或“情感对齐”(EA)。我们检查了EA的心理测量特征及其对催产素单剂量攻击的敏感性,一种神经肽,可增强SSD中社会情绪信息的显著性。相对于对照组,患者表现出受损的EA,和障碍与较差的社会认知技能和更严重的动机和快乐缺陷相关。将EA添加到具有基于语言的形式思维障碍(FTD)测量的逻辑回归模型中,可以改善患者与对照组的分类。最后,在患者中,催产素给药改善了EA,但未改善FTD。虽然需要额外的验证工作,这些初步结果表明,使用口语的自动化检测可能是评估SSD情绪处理的一种有前景的方法.
    Abnormal emotion processing is a core feature of schizophrenia spectrum disorders (SSDs) that encompasses multiple operations. While deficits in some areas have been well-characterized, we understand less about abnormalities in the emotion processing that happens through language, which is highly relevant for social life. Here, we introduce a novel method using deep learning to estimate emotion processing rapidly from spoken language, testing this approach in male-identified patients with SSDs (n = 37) and healthy controls (n = 51). Using free responses to evocative stimuli, we derived a measure of appropriateness, or \"emotional alignment\" (EA). We examined psychometric characteristics of EA and its sensitivity to a single-dose challenge of oxytocin, a neuropeptide shown to enhance the salience of socioemotional information in SSDs. Patients showed impaired EA relative to controls, and impairment correlated with poorer social cognitive skill and more severe motivation and pleasure deficits. Adding EA to a logistic regression model with language-based measures of formal thought disorder (FTD) improved classification of patients versus controls. Lastly, oxytocin administration improved EA but not FTD among patients. While additional validation work is needed, these initial results suggest that an automated assay using spoken language may be a promising approach to assess emotion processing in SSDs.

    异常视觉处理已被提出作为过度关注身体畸形障碍(BDD)的轻微外观缺陷的潜在机制。现有的BDD研究没有区分面部处理的各个阶段(特征,一阶配置,整体和二阶配置),这是情感识别等高阶过程所需的。这项研究调查了一种分层的视觉处理模型,以检查BDD中面部处理异常的性质。
    30名BDD参与者和27名健康对照者完成了Navon任务,特征和配置面部处理任务和面部情绪标记任务。
    在Navon任务上处理全局和局部非面部刺激时,BDD参与者的表现与控件相似,当检测到目标面部的特征和间距的细微变化时,当标记情感的面孔时。然而,BDD参与者在观看倒置面时表现较差,说明配置处理中的困难。
    这些发现仅部分支持先前的工作。然而,将结果与先前的发现进行综合表明,异质任务方法可能会导致不一致的发现。提供了有关对BDD异常最敏感的任务参数的建议。
    UNASSIGNED: Abnormal visual processing has been proposed as a mechanism underlying excessive focus on minor appearance flaws in body dysmorphic disorder (BDD). Existing BDD research has not differentiated the various stages of face processing (featural, first-order configural, holistic and second-order configural) that are required for higher-order processes such as emotion recognition. This study investigated a hierarchical visual processing model to examine the nature of abnormalities in face processing in BDD.
    UNASSIGNED: Thirty BDD participants and 27 healthy controls completed the Navon task, a featural and configural face processing task and a facial emotion labelling task.
    UNASSIGNED: BDD participants performed similarly to controls when processing global and local non-face stimuli on the Navon task, when detecting subtle changes in the features and spacing of a target face, and when labelling emotional faces. However, BDD participants displayed poorer performance when viewing inverted faces, indicating difficulties in configural processing.
    UNASSIGNED: The findings only partially support prior work. However, synthesis of results with previous findings indicates that heterogenous task methodologies may contribute to inconsistent findings. Recommendations are provided regarding the task parameters that appear most sensitive to abnormalities in BDD.

    情绪通过皮质途径在大脑中处理,负责详细意识识别,主要基于图像高空间频率(HSF),和皮质下路径,负责粗无意识处理,基于低SF(LSF)。然而,人们对这两种途径在老龄化中的功能可能发生的变化知之甚少。在当前的go/no-go在线任务中,当出现快乐或愤怒的面孔时,要求112名年轻人和111名老年人按下按钮(go),并抑制对中性面孔的反应(no-go)。面部刺激未过滤(宽带图像),在HSF和LSF过滤,和杂种(情绪表情的LSF叠加到具有中性表情的同一张脸的HSF)。所有刺激也都在垂直轴上旋转(上下颠倒),以研究衰老中面部的整体分析。结果显示,除混合刺激外,所有条件下,与年龄较大的参与者相比,年轻人的总体表现更好。在两个年龄组中都证实了预期的面部倒置效果。我们的结论是,除了随着年龄的增长,感知技能的整体恶化,皮质和皮质下途径的功能均未出现特定损害.
    Emotions are processed in the brain through a cortical route, responsible for detailed-conscious recognition and mainly based on image High Spatial Frequencies (HSF), and a subcortical route, responsible for coarse-unconscious processing and based on Low SF (LSF). However, little is known about possible changes in the functioning of the two routes in ageing. In the present go/no-go online task, 112 younger adults and 111 older adults were asked to press a button when a happy or angry face appeared (go) and to inhibit responses for neutral faces (no-go). Facial stimuli were presented unfiltered (broadband image), filtered at HSF and LSF, and hybrids (LSF of an emotional expression superimposed to the HSF of the same face with a neutral expression). All stimuli were also presented rotated on the vertical axis (upside-down) to investigate the global analysis of faces in ageing. Results showed an overall better performance of younger compared to older participants for all conditions except for hybrid stimuli. The expected face-inversion effect was confirmed in both age groups. We conclude that, besides an overall worsening of the perceptual skill with ageing, no specific impairment in the functioning of both the cortical and the subcortical route emerged.
