神经科学视角下的共情研究热点

共情是指个体对他人情绪和想法的感受及理解。近年来关于共情神经机制的研究日益增多,但多集中在情感共情、认知共情、生理性疼痛共情等方面,而对社会痛共情、积极共情和不对称共情反应的研究相对较少。且由于研究范式及个体差异等原因,研究结果之间也充满着争议。未来研究可以设计更具生态效度的共情研究范式、进一步深化和细化共情的神经机制研究、从神经机制角度探讨不同共情能力个体的特点及共情反应的调节因素。     

特质积极共情：一种高利他性的人格品质

特质积极共情是对他人积极情绪信息感受和分享的能力。目前对特质积极共情的研究刚刚起步,在相关概念内涵上还有待进一步丰富和检验。特质积极共情可以有效促进亲社会行为倾向和良好人际关系的形成,是一种高利他性的人格品质。未来研究中,需要在明确并丰富特质积极共情的内涵界定基础上,开发更为有效的测量工具,探讨其促进社会功能背后的作用机制,并开展提升积极共情能力的理论研究和教育实践。     

女大学生中共情对自我中心和利他行为关系的调节作用

目的：考察在女大学生中特质与状态共情对个体自我中心特质与利他行为之间的关系。方法：研究一采用问卷调查考察特质共情对自我中心特质与利他行为倾向的调节作用; 研究二采用行为实验 (自我中心特质高或低的女大学生) 来考察启动的状态共情对真实利他行为的影响。结果：共情特质/状态会与自我中心特质交互作用来影响个体的利他行为/倾向。结论：高共情状态/特质的被试其自我中心会降低利他行为/倾向, 而低共情状态或特质的被试无此倾向。     

认知神经研究中的积极共情

积极共情指个体对他人积极情绪状态的理解和间接分享过程。虽然它与消极共情在产生过程中都依赖于镜像神经系统和心理理论系统的活动, 但是两者在产生难度上不同。对于积极共情情感如何在大脑中表征的, 不同的研究者观点各异：一些认为与消极共情一致, 都集中在脑岛及其相关脑区; 而另一些则认为是大脑的愉悦系统。关于积极共情影响因素的研究主要集中于共情主体和客体的关系方面。今后需要进一步了解积极共情在产生机制和情感表征上的特点, 拓展其影响因素的研究并展开对特质积极共情神经基础的探讨。     

共情的神经生物基础

共情指个体感知或想象他人的情感, 并部分体验到他人感受的心理过程。共情包括情感共情和认知共情两个独立成分。情感共情的神经网络包括前脑岛(AI)、前扣带回(ACC)以及镜像神经系统(MNS), 认知共情的核心脑区是腹内侧前额叶(vmPFC)。共情的神经网络在个体发展中逐渐成熟并受到认知评价的调节。另外, 催产素和催产素受体基因多态性与共情密切联系。未来应该深入研究躯体感觉皮质在疼痛共情中的作用, 共情和亲身情感体验的神经网络的区别, 开展催产素改善共情缺陷个体的干预研究, 采用脑成像基因技术研究基因多态性与共情神经网络的关系以及提高共情研究范式的生态效度。     

冷酷无情特质：一种易于暴力犯罪的人格倾向

冷酷无情特质(callous unemotional trait, CU)是指对他人冷漠、缺乏罪责感、低共情的一种人格倾向, 伴随有高频率和高破坏性的反社会行为甚至暴力犯罪。CU特质者在情感上表现为对负性情绪加工不敏感, 缺乏共情; 在认知上表现出追求奖赏、忽视惩罚; 在生物学方面, CU特质者生理唤醒水平低、皮质醇水平低、杏仁核和腹内侧前额叶活动异常。未来研究的方向是修订发展本土化CU特质量表、探析CU特质者的性别差异、梳理CU与品行障碍等其他精神障碍的关系、为暴力犯循证矫正的方案设计提供科学依据。     

疼痛共情的神经机制

疼痛是一种多维度的体验。情感成分和感觉成分是疼痛体验的主要成分,二者有着不同的神经机制。疼痛共情是痛觉"共鸣"的情绪反应,其神经机制的研究也围绕疼痛的情感成分和感觉成分展开。疼痛共情的情感成分的相关脑区主要有前扣带皮层和脑岛等脑区,与自身疼痛时相比,它们的激活位点及所处的神经网络存在差异;疼痛共情的感觉成分主要与初级感觉皮层以及一些其它的躯体感觉皮层有关,对它们的激活情况的研究受技术手段和实验范式的影响较大。未来的研究应从技术手段、分析方法及实验操作上予以关注。     

动物和人类的利他本性:共情的进化

共情指个体感知或想象其他个体的情感,并部分体验到其他个体感受的心理过程.利他指以增加其他个体的福利为最终目标的动机.共情起源于动物的亲代养育行为,其神经基础来源于古老的情感系统.共情从动物低水平的情绪感染逐渐进化到同情关注以及观点采择共情.另外,共情具有良好的环境适应性.未来可以进一步研究动物与人类的共情和利他行为的异同,加大研究动物的高级共情能力和利他行为以及深入研究共情受社会因素的调节机制.     

自闭特质对疼痛共情的影响：疼痛负性情绪和认知的中介作用

已有研究提示自闭症个体的疼痛共情缺陷可能源于自身疼痛的异常。鉴于高自闭特质与自闭症的相似性,本研究分别通过实验范式和问卷调查评估了状态和特质共情,旨在刻画自闭特质、自身疼痛与共情之间的联系。在假双人疼痛共情范式中,高自闭特质个体在目睹他人接受疼痛时P2响应更强,不愉悦度评分更高,且部分源于对疼痛的高恐惧水平。问卷调查结果发现,自闭特质水平越高,在共情特质量表的观点采择维度得分越低,而个人痛苦维度得分越高,其中疼痛恐惧和灾难化中介了自闭特质与个人痛苦之间的联系。因此,高自闭特质个体表现出高水平的状态和特质情绪共情,且部分源于对疼痛存在更为负面的情绪和认知。这支持从自身疼痛异常的角度去理解高自闭特质和自闭症群体的共情等社会功能障碍,为临床治疗和干预提供了潜在的靶点。     

大学生自尊和宽恕的关系:一个有调节的中介模型

采用问卷法对550名大学生进行调查研究,考察自尊对大学生宽恕的影响,同时考察共情在其中的中介作用,以及该过程是否受到特质愤怒的调节。结果表明:(1)大学生自尊与宽恕存在显著的正相关;(2)共情在大学生自尊和宽恕关系中起到完全中介作用;(3)特质愤怒在共情和宽恕之间具有调节效应,特质愤怒越高,共情对宽恕影响越小。     

共情与中国民族音乐情绪识别的关系：来自ERP的证据

音乐情绪识别能力是利用音乐开展情绪调节的基本条件。传统的以五声音阶为基础的具有独特韵味的中国民族音乐反映了中国人独有的情感和价值观念, 在情绪调节和音乐治疗方面具有积极的作用, 是研究音乐情绪识别的有效音乐刺激。本研究采用跨通道情绪启动范式, 通过人际反应指针问卷筛选出高、低共情组被试各36人参加脑电实验, 考察共情能力对中国民族音乐情绪识别的影响。脑电数据显示, 在进行中国民族音乐情绪内隐识别时, 将宫调和羽调音乐作为启动刺激, 诱发了中期的P2、N400以及晚期正成分LPC (Late Positive Component)。低共情组P2和N400成分的波幅大于高共情组, 高共情组LPC成分的波幅大于低共情组。本研究第一次从电生理层面考察了不同共情能力的个体在进行中国民族音乐情绪识别时的神经反应差异。高低共情组在中国民族音乐情绪识别不同阶段的注意投入可能影响了其对音乐刺激的感受, 进而影响音乐情绪识别。     

Cannot avert the eyes: reduced attentional blink toward others’ emotional expressions in empathic people

Empathy is one of the core components of social interaction. Although current models of empathy emphasize the role of attention, few studies have directly examined the relationship between attentional processes and individual differences in empathy. This study hypothesized that empathic people would process emotional expressions more efficiently and automatically compared to less empathic people. Crucially, such a processing advantage should be present only for faces of others compared to one’s own face. To test this hypothesis, 100 healthy participants varying in their self-reported empathy levels underwent an attentional blink task that tested preferential attentional processing. Results showed a diminished attentional blink effect for sad faces of others in the high-empathy group. Additionally, performance differences in the task were related to both trait empathy and daily prosocial behavior. Overall, our results show that emotional stimuli preferentially capture the attention of empathic people, leading to automatic processing.     

自爱与他爱:自恋、共情与内隐利他的关系

自恋者具有低共情的人格特征,而共情是引发利他行为的重要动力。本文通过两个实验研究试图揭示不同情境下,自恋对共情与内隐利他的影响。结果表明:(1)自恋组与非自恋组被试均存在内隐利他倾向,且自恋组的内隐利他倾向显著低于非自恋组;(2)自恋组的共情能力显著低于非自恋组,其中,自恋组在情绪共情上显著低于非自恋组被试,两组在认知共情上差异不显著;(3)共情诱发对自恋组被试的共情与内隐利他均有显著影响。启动条件下自恋组被试的共情水平与内隐利他倾向显著高于控制条件下自恋组被试,且达到与非自恋组被试相同的水平,而非自恋组被试的共情与内隐利他倾向在两种实验条件下差异不显著;(4)共情诱发显著提高了自恋组被试的情感而非认知共情水平。     

父母教养方式对中职生亲社会行为的影响:两类共情的中介作用

探讨父母教养方式对中职生亲社会行为的影响,分别采用问卷法和实验法检验特质共情与状态共情 在这个影响过程中的中介效应。 结果发现:(1)情感温暖、信任鼓励型的父母教养方式对中职生亲社会行为有正向预测作用; 专制、溺爱型父母教养方式对中职生亲社会行为起负向预测作用。(2)特质共情在情感温暖型、信任鼓励型父母教养方式与中职生亲社会行为之间起部分中介作用。(3)经试验操纵的状态共情的中介效应与特质共情的中介效应同样显著。结论:积极的父母教养方式通过影响中职生的共情进而影响其亲社会行为。     

Day-to-Day Variability in Empathy as a Function of Daily Events and Mood

Despite broad agreement that understanding a personality construct requires integrating trait and state levels of analysis, few studies have explicitly attempted such an integration. The present study did this by examining the relationships between trait and state measures of empathy. State measures were taken daily, with a focus on the day level (within-person) covariation between empathy and daily mood and events. Twice a week for up to 10 weeks, 103 participants provided measures of their daily empathy and mood (NA and PA) and described the events that occurred each day. Multilevel random coefficient modeling analyses found that daily empathy covaried positively with the impact of daily positive and negative social events and with daily positive and negative affect. Empathy did not covary with achievement-related events. Analyses that simultaneously included empathy, mood, and events suggested that daily NA mediated relationships between daily empathy and daily negative social events. Although mean daily empathy was positively related to trait empathy, trait empathy did not moderate relationships between daily empathy and events nor between daily empathy and mood. Moreover, daily empathy did not covary with daily depressogenic thinking, need for cognition, nor self-esteem, suggesting that empathy is distinct from these constructs. Possible mechanisms linking social events and empathy, such as emotional contagion, are discussed.     

Motor,affective and cognitive empathy in adolescence: Interrelations between facial electromyography and self-reported trait and state measures

This study examined interrelations of trait and state empathy in an adolescent sample. Self-reported affective trait empathy and cognitive trait empathy were assessed during a home visit. During a test session at the university, motor empathy (facial electromyography), and self-reported affective and cognitive state empathy were assessed in response to empathy-inducing film clips portraying happiness and sadness. Adolescents who responded with stronger motor empathy consistently reported higher affective state empathy. Adolescents' motor empathy was also positively related to cognitive state empathy, either directly or indirectly via affective state empathy. Whereas trait empathy was consistently, but modestly, related to state empathy with sadness, for state empathy with happiness few trait–state associations were found. Together, the findings provide support for the notion that empathy is a multi-faceted phenomenon. Motor, affective and cognitive empathy seem to be related processes, each playing a different role in the ability to understand and share others' feelings.     

The meaning in empathy: distinguishing conceptual encoding from facial mimicry, trait empathy, and attention to emotion

In order to truly empathise with another, we need to recognise and understand how they feel. Perception-action models of empathy predict that attending to another's emotion will spontaneously activate the observer's own conceptual knowledge for the state, but it is unclear how this activation is related to facial mimicry, trait empathy, or attention to emotion more generally. In the current study, participants did spontaneously encode background facial expressions at a conceptual level even though they were irrelevant to the task (the Emostroop effect; Preston & Stansfield, 2008), but this encoding was not associated with mimicry of the faces, trait empathy, the ability to resolve competing semantic representations (Colour-naming Stroop task), or the tendency to be distracted by emotional information more generally (Intrusive Cognitions task). Our results suggest that trait empathy increases attention to emotional information, but conceptual encoding occurs across individuals as a natural consequence of attended perception.     

The effects of dispositional empathy on emotional reactions and helping: A multidimensional approach

Recent research indicates that an affective state termed empathic emotion, and characterized by feelings of sympathy and compassion for another, is associated with altruistic responding. That is, persons experiencing high levels of empathic emotion offer help to another even when escape from the situation is easy. Persons experiencing high levels of another emotional state—personal distress—help much less when escape from the situation is easy. A study was conducted to test two related hypotheses. The first was that individual differences in empathy can influence empathic emotion and personal distress, above and beyond the influence of situational factors. The second hypothesis was that this effect of individual differences is due to variation in emotional and not cognitive empathy. The results provide support for both hypotheses. Regarding hypothesis 1, a significantly greater proportion of the variance in emotional reactions was accounted for when individual difference factors were included as predictors. Hypothesis 2 was also supported: It was found that a dispositional measure of emotional empathy was clearly related, and a dispositional measure of cognitive empathy was clearly unrelated, to these emotional reactions. The results provide support for a multidimensional view of empathy.
