微表情是人压抑的真实情绪的泄露, 时间约为1/25~1/2 s, 常出现在说谎情境, 可能源于椎体束运动系统控制的自主面部运动和椎体束外运动系统控制的非自主面部运动的“拔河比赛”。已有研究构建了微表情数据库, 开发了BART和JACBART等微表情识别测验以及METT训练, 并探讨了微表情识别及训练与认知、人格、文化、职业等的关系。但这些研究考察的中性表情背景下微表情只是镶嵌在各表情背景下真实微表情的特例, 生态程度不高; 少量研究探索了表情背景对微表情识别的影响但未建立标准测验。未来应开发生态化微表情识别标准测验和训练, 尝试跨越微表情发生和识别的界限, 并采用生理−心理、电生理和脑成像技术探索其机制。 相似文献

经典JACBART微表情识别测验只考察平静表情背景下微表情识别,生态效度不高。本研究创建生态化微表情识别测验,考察所有7种基本表情背景下的6种微表情识别特征。结果发现:(1)该测验具有良好的重测信度、校标效度和生态效度,能够稳定有效地测量生态化微表情识别。(2)信效度检验揭示了生态化微表情识别特征。某些生态化微表情识别存在训练效应。生态化微表情与经典微表情或普通表情普遍相关。恐惧、悲伤、厌恶、愤怒微表情背景主效应显著;惊讶和愉快微表情背景主效应不显著,成对比较发现各背景下惊讶/愉快微表情差异不显著,但是与普通表情有广泛的显著差异。用不同背景下微表情识别正确率的标准差定义生态化微表情识别波动,发现生态化微表情识别具有稳定的波动性。 相似文献

微表情是一种持续时间极短、不易被察觉的面部动作, 揭示了个体的真实情绪, 可以被广泛地应用于谎言识别等领域。而微表情检测的研究受到小样本问题的限制。针对该问题, 本文结合计算机视觉技术与认知心理学实验方法进行探索。首先, 结合眼动技术和呈现-判断范式与阈下情绪启动效应的行为实验范式, 考察微表情识别中选择注意分配的认知机制, 细化人类识别微表情时的特征兴趣区域。其次, 结合人类注意机制, 提出基于自监督学习的多模态微表情检测方法。通过理论和关键技术的突破, 为真实场景下微表情检测的应用奠定基础。 相似文献

隐藏情绪识别对公共安全防范与预警具有重要的意义。微表情是揭示隐藏情绪的一条重要通道。但目前隐藏情绪研究较少且微表情因其细微幅度与快速出现等特性难以识别, 其研究尚未在实际中广泛应用。因为, 隐藏情绪的认知与表达机理亟需系统的研究,采集实际场景中的微表情数据, 并以脑电信号辅助微表情的精确标注是提高微表情标注效率的有效途径。深入研究微表情识别方法, 并辅以人脸颜色、注视估计和非接触生理信号等多通道数据, 以检测与识别隐藏情绪。社会公共安全是隐藏情绪分析和识别的典型场景。面向精神疾病患者两害行为(即危害自身或他人的危险行为)风险评估和服刑人员会见场景隐藏情绪检测, 可以有效地对相应系统和方法进行验证和修正。 相似文献

本研究采用JACBART范式,通过考察增强面部反馈对高强度微表情识别的影响(实验1)和增强面部反馈对低强度微表情识别的影响(实验2)来探究面部反馈在微表情识别过程中的作用。结果发现:(1)增强面部反馈不能提高被试对高强度微表情识别的准确率;(2)增强面部反馈降低了低强度微表情的识别准确率。研究提示面部反馈参与了微表情的识别过程,但它是一种对微表情识别“有害”的抑制性线索,且这一线索的作用受微表情强度的调节。 相似文献

众多研究表明微表情和欺骗密切相关,考察如何利用微表情进行欺骗检测是微表情研究的一个重要领域。通过对欺骗与欺骗检测的基本概念、微表情作为欺骗检测线索的理论依据及相关应用等的较全面阐述,论证了微表情作为欺骗检测的情绪线索具有可行性和一定的有效性,且相比其他生理、认知的欺骗检测线索具有更多的优势,在国家安全、临床医学等领域的欺骗检测中已有较多的应用。针对微表情在欺骗检测中的应用存在的争议,指出未来应进一步研究欺骗是否一定伴随着微表情、微表情训练能否促进欺骗检测能力、如何提高微表情实验室研究的外部效度、个体差异对微表情利用的影响等核心问题,并指出了可能的解决途径。 相似文献

本研究通过两个模拟量刑实验,具体考察了案件无关情绪和案件相关情绪对法官量刑决策的影响。结果发现案件无关情绪显著影响法官量刑。法官在悲伤情绪下所判刑期短于中性情绪,愉悦和愤怒情绪与中性情绪下刑期无显著差异。案件相关情绪显著影响法官量刑,法官同情情绪下刑期更短,厌恶和愤怒情绪下刑期更长。性别对法官量刑无显著影响,从业时间对法官量刑无显著影响。性别和从业时间对案件无关情绪和相关情绪诱发均无显著影响。 相似文献

A growing literature suggests robust associations between dimensions of emotion regulation and emotional disorder psychopathology. However, limited research has investigated associations of emotion regulation dimensions across several emotional disorders (transdiagnostic associations), or the incremental validity of emotion regulation versus the higher-order construct of neuroticism. The current study used exploratory structural equation modeling and a large clinical sample (N = 1,138) to: (a) develop a multidimensional emotion regulation measurement model, (b) evaluate the differential associations between latent emotion regulation dimensions and five latent emotional disorder symptom dimensions (social anxiety, depression, agoraphobia/panic, obsessions/compulsions, generalized worry), and (c) determine the incremental contribution of emotion regulation in predicting symptom dimensions beyond neuroticism. The best-fitting measurement model of emotion regulation included four dimensions: Problematic Responses, Poor Recognition/Clarity, Negative Thinking, and Emotional Inhibition/Suppression. Although many zero-order associations between the four latent emotion regulation dimensions and five latent symptom dimensions were significant, few associations remained significant in a structural regression model that included neuroticism. Specifically, Negative Thinking and Problematic Responses incrementally predicted depression symptoms, while Emotional Inhibition/Suppression predicted both social anxiety and depression symptoms. Associations between neuroticism and the emotional disorder dimensions were similar regardless of whether the emotion regulation dimensions were held constant. These results suggest that self-reported emotion regulation dimensions are associated with the severity and expression of a range of emotional disorder symptoms, but that some emotion regulation dimensions have limited incremental validity after accounting for general emotional reactivity. Studies of emotion regulation should assess neuroticism as a key covariate. 相似文献

基于悲伤情绪的功能及效应,提出死亡意识的“悲伤管理假设”。实验1采用电生理、微表情、主观报告等方法探索死亡意识伴随的情绪变化;实验2和实验3对比死亡意识的“悲伤管理”和“恐惧管理”,并探索情绪的中介作用。结果发现:死亡意识诱发悲伤和恐惧(尤其是悲伤),且死亡反思诱发更多的悲伤;恐惧在死亡意识与外在人生目标间起中介作用;悲伤(而非恐惧)背景音乐下,死亡意识使个体更重视内在人生目标。上述结果为死亡意识的“悲伤管理”提供了实证依据,表明在悲伤的情绪中加工死亡意识可能促进个体的内在成长,这对疫情等社会灾难时期的心理救援具有启示意义。 相似文献

Two studies investigated the utility of indirect scaling methods, based on graded pair comparisons, for the testing of quantitative emotion theories. In Study 1, we measured the intensity of relief and disappointment caused by lottery outcomes, and in Study 2, the intensity of disgust evoked by pictures, using both direct intensity ratings and graded pair comparisons. The stimuli were systematically constructed to reflect variables expected to influence the intensity of the emotions according to theoretical models of relief/disappointment and disgust, respectively. Two probabilistic scaling methods were used to estimate scale values from the pair comparison judgements: Additive functional measurement (AFM) and maximum likelihood difference scaling (MLDS). The emotion models were fitted to the direct and indirect intensity measurements using nonlinear regression (Study 1) and analysis of variance (Study 2). Both studies found substantially improved fits of the emotion models for the indirectly determined emotion intensities, with their advantage being evident particularly at the level of individual participants. The results suggest that indirect scaling methods yield more precise measurements of emotion intensity than rating scales and thereby provide stronger tests of emotion theories in general and quantitative emotion theories in particular. 相似文献

This investigation analyzed the methods used over the past 35 years to study emotion regulation (ER) in children. Articles published from 1975 through 2010 were identified in 42 child clinical, developmental, and emotion psychology journals. Overall, 61.1% of published ER articles relied on one method and 23.6% used two methods. Analyses revealed (a) 82.8% of published ER research occurring within the past decade; (b) higher rates of observational methods with infant and toddler/preschool samples, but more use of self-report methodology with middle childhood and adolescent samples; (c) a longer history of published ER research with samples of infants to 5-year-olds, including the use of more longitudinal design, compared with older samples; and (d) a positive association between journal impact ratings and the use of physiological and observational measurement. Review of the measurement tools used to capture ER revealed great diversity in how emotion processes are understood and evaluated. 相似文献
