自我概念心理表征的文化神经科学研究

人类自我概念的心理表征在心理学和哲学有深入的研究, 跨文化心理学研究揭示了东西方文化自我概念的结构差异。近年来神经科学借助脑功能成像开始研究自我相关信息加工过程的神经机制, 并探讨是否存在文化特异的自我概念的认知神经表征。跨文化神经成像研究表明自我概念在知觉水平和人格特征表征方面都存在文化差异, 本文综述该领域的研究进展。跨文化和文化启动神经成像研究结果有助于我们理解自我概念表征文化差异背后的神经机制。这些研究推动了文化神经科学的发展。     

共情与青少年内外化问题的关系及影响机制

内外化问题是青少年最常见的心理行为问题,共情与青少年内外化问题具有重要联系,但以往研究青少年内外化问题的时候不注重共情不同成分的区分;即使区分了共情的不同成分,认知共情和情绪共情作为共情的不同成分和内外化问题的关系仍旧存在一定争议,且共情对内外化问题影响的机制鲜有探讨。本文首先综述了认知共情和情绪共情与青少年内外化问题的关系,并借助共情的发生过程（自我-他人模型）理论、发展过程（风险性发展模型）理论和相关神经生理因素,为理解共情对青少年内外化问题的影响机制提供了解释。未来研究可明确共情的定义,发展更生态化的测评方式,并进一步探索影响因素及机制,结合和关注个体特点、特殊群体及文化背景,以便为揭示共情与青少年内外化问题构建更系统的理论。     

共情对亲社会行为的影响及神经基础

亲社会行为是指那些使他人获益的行为,这类行为具有重要的进化意义和现实意义。作为影响亲社会行为的重要因素,共情在认知神经科学领域得到了广泛研究。脑岛等脑区的激活与消极情绪体验有关,是情绪共情的神经基础,利于产生亲社会行为动机;颞顶联合区等脑区参与对他人意图的理解,是认知共情的神经基础,利于个体选择有效方式帮助别人。女性在共情时激活额下回等与情绪有关的脑区,而男性在共情时激活颞顶联合区等与认知有关的脑区,这为男女个体在亲社会行为表现上的差异提供了新证据。未来研究应完善与亲社会行为有关的脑区功能的解释,综合多种影响因素,结合病理学研究考察共情对亲社会行为的影响及神经基础。     

特质敬畏对亲社会倾向的正向预测：自我超越和共情的多重中介作用

敬畏对内能影响个体的精神世界,实现自我超越,对外能使个体更多地关注他人;且自我超越也能促进个体对他人的共情关注。但目前还未有实证研究探讨敬畏是否能通过共情以及自我超越−共情的中介预测亲社会倾向。为检验这一假设,本研究招募了1347名大学生并测量了其敬畏特质、自我超越、共情和亲社会倾向。结果显示：（1）敬畏、自我超越、共情和亲社会倾向各维度两两相关显著;（2）敬畏直接预测亲社会倾向各维度,也能通过自我超越和共情的多重中介间接预测,且自我超越的中介效应最大。本研究从内、外因素进一步深化了对敬畏与亲社会倾向关系的认识,频繁的敬畏体验有助于提升个体的自我超越及对他人的共情关注,促进亲社会倾向。     

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。     

自我-他人重叠影响疼痛共情的ERP研究

为探究自我-他人重叠影响疼痛共情的神经机制,记录并分析被试在高、中、低重叠程度条件下共情判断的脑电活动。发现在早期N2上,重叠程度三水平间差异显著,表现为密友＜熟人＜陌生人（密友与熟人差异边缘显著）;在晚期P3上,疼痛条件下重叠程度间呈显著差异,密友比熟人、陌生人显著要大;在LPP上疼痛条件诱发更大波幅。表明早期阶段（N2）区分不同重叠程度,可能是对威胁性刺激的检测阶段,自我-他人重叠程度影响共情加工晚期阶段（P3）的社会认知评价加工。

道德决策的机制及干预研究:自我相关性与风险水平的作用

现有的道德决策脑机制研究更多地关注了认知和情绪的交互作用,较少关注个体对"自我相关性"和"风险水平"信息的整合加工,更是忽视了帮助情境和伤害情境下道德决策的心理与脑机制的异同。因此,有必要通过行为、事件相关电位(ERP)和多模态脑功能成像(f MRI)等多种方法来系统考察帮助和伤害情境下自我相关性和风险水平交互影响道德决策的认知和神经机制,并进一步探讨共情训练对道德决策的干预作用。旨在揭示道德决策的时间进程和神经基础;探寻自我相关性与风险水平对道德决策的影响,及其在不同情境和共情水平下可能存在的变异;共情训练能否有效提升个体的道德决策水平。     

催产素对共情反应的影响及其作用机制

催产素是一种亲社会激素, 对人类的共情反应有重要的影响作用, 主要表现为可以促进情绪识别率, 增强对他人不幸的共情关注, 并弱化自身的个体忧伤水平等。从作用机制上来看, 催产素可能是通过促进具身模仿能力, 弱化自我中心主义倾向及调节情感表征过程来影响人类的共情反应的。未来研究可以进一步关注催产素对不同类型共情反应的影响及其催产素影响共情反应的性别差异问题, 并积极将催产素应用于共情缺陷的临床干预中。     

群体共情对群际关系的影响：基于社会冲突解决的视角

摘要：群体共情是指群体成员内化和间接体验另一群体成员的认知和情绪情感的过程。群体共情与个体共情不同,表现在身份感、共情偏好和文化影响的差异等方面。群体共情对群际关系具有促进作用,有助于减少群际冲突,促进群际亲社会行为。共情动机和文化框架转换是分析群体共情对群际关系促进机制的两个视角。未来研究可以探索群体共情与个体共情神经机制的差异,建立群体共情对群际关系影响的综合模型,探索群体共情在群际关系改善中的作用机制。     

正性情绪诱导下的自我参照加工：来自ERPs的证据

采用事件相关电位考察正性情绪对自我参照加工程度效应的影响。实验采用图片启动范式, 先呈现情绪图片, 然后再呈现自我参照刺激。实验发现, 在P2上, 中性情绪条件比正性情绪条件激发了更大的波幅, 高自我相关的刺激比其它刺激诱发了更短的P2潜伏期; 在N2上, 高自我相关名字比中等自我相关名字和非自我相关名字诱发了更小的N2的波幅和更长潜伏期; 在P3上, 高自我相关名字比中等自我相关名字和非自我相关名字诱发了更大的P3波幅, 中等自我相关名字比非自我相关名字诱发了更大的P3波幅。实验结果表明, 人类大脑对正性情绪刺激的加工可能是不敏感的。无论在正性情绪启动还是中性启动的影响下, 自我参照加工都能展现出稳定的特征, 而且高自我相关的刺激会得到更为深入和精细的加工, 表现出自我参照加工的程度效应。     

Effects of Damage to Right-Hemisphere Brain Structures on Spontaneous Emotional and Social Judgments

Recent work in cognitive and social neuroscience has focused on the neural substrates of social judgment. The present study explores the effects of damage to the right-hemisphere somatosensory cortices (RSS), a region known for its role in emotion recognition. Seven subjects with RSS damage were shown a short movie depicting objects that move in socially suggestive ways, a stimulus that typically elicits spontaneous social and emotional attributions from normal subjects. The spontaneous verbal responses of RSS-damaged subjects to this movie were compared to those of normal subjects as well as brain-damaged control subjects; the data were derived using a word count and categorization computer program. This method measures spontaneous social and emotional judgments rather than the more typical rating and labeling measures used in neuropsychological studies of social judgment. As predicted, relative to brain-damaged and normal controls, subjects with RSS damage reacted to the stimulus movie with fewer words in categories describing emotional and social processes, despite using a similar total number of words (and slightly more words describing movement, a control category). These results provide further evidence for the role of the RSS in social/emotional processing and identify a role for the RSS in automatic representation in ourselves of body states of others to foster emotion recognition and social cognition.     

More of myself: Manipulating interoceptive awareness by heightened attention to bodily and narrative aspects of the self

Psychology distinguishes between a bodily and a narrative self. Within neuroscience, models of the bodily self are based on exteroceptive sensorimotor processes or on the integration of interoceptive sensations. Recent research has revealed interactions between interoceptive and exteroceptive processing of self-related information, for example that mirror self-observation can improve interoceptive awareness. Using heartbeat perception, we measured the effect on interoceptive awareness of two experimental manipulations, designed to heighten attention to bodily and narrative aspects of the self. Participants gazed at a photograph of their own face or at self-relevant words. In both experimental conditions interoceptive awareness was significantly increased, compared to baseline. Results show that attention to narrative aspects of self, previously regarded as relying on higher-order processes, has an effect similar to self-face stimuli in improving interoceptive awareness. Our findings extend the previously observed interaction between the bodily self and interoception to more abstract amodal representations of the self.     

Shared Knowledge Matters: Culture as Intersubjective Representations

The intersubjective representation approach to culture focuses on cultural members’ shared knowledge representations about the culture that they are in. Members of the same culture tend to share certain knowledge representations of the central characteristics of the culture. These shared cultural representations are established and perpetuated through dynamic communicative processes. Recent empirical research has provided support for the incremental value of intersubjective cultural representations in research on cultural identity, social cognition, and behaviors. The intersubjective representation approach complements extant research on culture as self and external artifacts. In doing so, it allows for a more comprehensive understanding of culture’s role in social and personality psychological processes.     

A multi‐process model of self‐regulation: Influences of Mindfulness,Integrative Self‐Knowledge and Self‐Control in Iran

Self‐regulation presumably rests upon multiple processes that include an awareness of ongoing self‐experience, enduring self‐knowledge and self‐control. The present investigation tested this multi‐process model using the Five‐Facet Mindfulness Questionnaire (FFMQ) and the Integrative Self‐Knowledge and Brief Self‐Control Scales. Using a sample of 1162 Iranian university students, we confirmed the five‐factor structure of the FFMQ in Iran and documented its factorial invariance across males and females. Self‐regulatory variables correlated negatively with Perceived Stress, Depression, and Anxiety and positively with Self‐Esteem and Satisfaction with Life. Partial mediation effects confirmed that self‐regulatory measures ameliorated the disturbing effects of Perceived Stress. Integrative Self‐Knowledge and Self‐Control interacted to partially mediate the association of Perceived Stress with lower levels of Satisfaction with Life. Integrative Self‐Knowledge, alone or in interaction with Self‐Control, was the only self‐regulation variable to display the expected mediation of Perceived Stress associations with all other measures. Self‐Control failed to be implicated in self‐regulation only in the mediation of Anxiety. These data confirmed the need to further examine this multi‐process model of self‐regulation.     

Target self-relevance speeds visual search responses but does not improve search efficiency

ABSTRACT

In a variety of contexts, arbitrarily associating one’s self with a stimulus improves performance relative to stimuli that are not self-associated, implying enhanced processing of self-associated stimuli (“self-relevance” effects). Self-relevance has been proposed to influence diverse aspects of cognition, including the perceptual prioritization of self-relevant stimuli (“self-prioritization” effects). We sought to elucidate the mechanisms of self-prioritization by using a visual search paradigm. In three experiments, subjects learned two stimulus-label combinations (SELF and OTHER), and then searched for one of those stimuli (cued by the label) on each trial, with a variable number of distractors present on each trial. We hypothesized that, if self-relevance enhances the perceptual salience of the stimuli pre-attentively, then the self-relevance of a target should result in improved search efficiency. In three experiments using conjunction-defined (Experiments 1–2) and feature-defined (Experiment 3) targets, we found that self-relevant targets were associated with overall faster responses than non-self-relevant targets (an intercept effect). However, the slopes of the search size by reaction time (RT) function were never significantly different between the self-relevant and non-self-relevant conditions, counter to the hypothesis that self-prioritization is pre-attentive. These results constitute novel evidence that self-relevance affects visual search performance, but they also cast doubt on the possibility that self-relevance enhances the perceptual salience of a target in a manner similar to physical manipulations. We propose that the self-relevance of a stimulus alters processing only after the self-relevant item has been attended.     

人际互动中的“自我-他人”区分:多水平的探索

人际互动的根本问题在于我们如何在表征自身想法和感受的同时试图去理解他人的心理和情感状态, 以驾驭复杂的社交环境。最近研究发现个体主要通过模拟自我加工过程实现对他人的理解, 但这种自我加工以及心理模拟在一定程度上混淆了自我与他人。因此, 为进行成功的人际互动, 大脑必须灵活区分自我和他人相关的表征, 这种能力被称为“自我-他人”区分(self-other distinction, SOD)。通过探讨感知、动作、认知以及情感等不同加工水平社会认知过程中的“自我-他人”区分及相应的研究范式, 实现对人际互动过程更全面而深入的理解, 为改善社会认知、情感障碍以及自闭症的干预提供依据。在此基础上, 提出了具体的研究展望。     

内隐自我正面偏见的机制及可变性

自我正面偏见是指对大多数个体来说, 其自我相关信息与正性情绪效价联系紧密, 个体倾向于把正面结果或特质归因于自我内部稳定的人格特征, 而认为负面结果或特质与自己的人格特征不相关。本项目从自我正面偏见的文化相对论与文化普遍论之争出发, 采用行为和认知神经科学技术, 试图证实集体主义文化下自我正面偏见的存在, 并对照外显自我正面偏见, 考察内隐层面上的自我正面偏见及其可变性, 探索抑郁个体的内隐自我相关信息加工的改善, 了解其大脑神经基础, 揭示内隐自我正面偏见的性质与特征, 验证和完善自我相关信息与情绪信息的功能加工层次模型。研究结果不仅有助于从内隐层面上了解自我与情绪的复杂关系, 而且还将对其神经基础做出重要探索, 更深入地解读中国人的自我的本质。     

The retrieval of self-defining memories is associated with the activation of specific working selves

This article presents two studies that investigated the impact of the retrieval of self-defining memories on individuals' sense of self. Participants recalled positive and/or negative self-defining memories, rated memory characteristics and completed measures focusing on different self-aspects. Study 1 found that participants reported higher state self-esteem after recalling a positive memory than after recalling a negative one. They also reported lower negative self-consistency and higher state self-concept clarity and positive self-consistency, but this result became non-significant after controlling for state self-esteem. Study 2 found that participants reported higher state self-esteem, a marginally higher proportion of recreation/exploration, goals and a marginally lower proportion of achievement goals after recalling a positive memory than after recalling a negative one. They also reported a higher proportion of self-cognitions referring to emotional states after recalling memories from which they had not abstracted meaning than after recalling memories from which they had done this. These findings suggest that the retrieval of vivid, emotional and highly self-relevant memories may be accompanied by the activation of specific self-representations or working selves. They also suggest that the experience of memory-related intrusive images may temporarily influence individuals' sense of self. The implications of these findings for clinical practice are discussed.     

从心理咨询与治疗的角度看自我

心理咨询和治疗离不开对自我的关注, 精神分析、行为疗法和认知疗法对自我的关注局限于认知或行为层面, 而新兴的正念疗法填补了对自我身体和感受层面关注的空白。具身认知和具身自我实验, 以及认知神经科学研究也证明了身体、感知觉和认知情绪的密切关系, 及其与自我的息息相关。本文在整合已有心理疗法和实验研究的基础上, 提出一种整体观的自我结构, 即自我是理性(符号机能、认知情绪)、感性(非符号机能、感知觉)、身体(生理机能)的综合体, 缺一不可。
