社会互动视角下的有意识情绪感染

随着超扫描技术的兴起,研究者们开始关注社会互动情境中有意识情绪感染的脑间神经同步问题。研究发现,脑间神经同步可能是有意识情绪感染在神经层面的指标。“发送者-接收者”模式的应用使得研究者们思考自我-他人重叠理论是否可作为有意识情绪感染脑间神经同步的心理解释机制。未来研究可采用基于自然情境的“发送者-接收者”模式以及“自然讨论”模式来探究不同社会因素对有意识情绪感染及其脑间同步机制的影响;未来还应构建有意识情绪感染的多模态超扫描平台,以此拓展相关研究。     

基础认知与社会认知中内隐过程及其脑机制*

认知过程及其脑机制是心理学研究的重要内容。社会认知是人们在社会生活中对他人行为的意图及情感的认识,是人际互动的重要方面,具有深刻的理论和实践意义。本文全面深入地对社会认知和基础认知中自动加工过程进行了研究综述,对基础认知与社会认知的研究方式进行了比较。自动加工过程是社会认知和基础认知中都存在的重要过程,从脑机制研究角度,相关的电生理学指标(如N400等)都可以作为研究的指标来考察社会认知中的自动加工过程。本文从社会认知与基础认知的比较入手,介绍了各种领域的研究方法,特别是事件相关电位技术等认知神经科学研究方法。     

Cognitive neuroscience: origins and promise

Both Freud and Wundt had hoped to base psychology on an understanding of the neural basis of mental events. Their efforts were unsuccessful because the structure and function of the human brain was not available for empirical study at the physiological level. Over the last part of this century, there has been amazing growth and vitality in the field of human brain function. In this paper, we trace critical developments in the fields of cognitive psychology, neuropsychology, and brain imaging related to the development of cognitive neuroscience. Cognitive Neuroscience has established that the decomposition of mental events can be united with an understanding of the mental and emotional computations carried out by the human brain. Cognitive neuroscience has the capability of influencing psychology in diverse areas from how children develop to how adults age; from how humans learn to how we imagine; from volitional control to psychopathologies.     

人脑的奥秘能否由人脑自身揭示--浅谈神经科学现代研究方法

神经科学研究是学科、多层次的。神经科学的每一次飞跃几乎都与某种研究方法的出现有关。从形态学的束路追踪法、组织化学法、原位杂交法、其聚焦激光扫描显微镜,到生理学的脑内微透析术、脑片、微电泳及行为学方法;从电生理的电压钳、膜片和脑电波,到生物化学的层析法、放射免疫法、免疫印迹法等;从种类繁多的分子生物学方法到各种脑成像技术。每种新方法的出现都打开了一扇门,引入一个新领域。实践证明,人脑即使不能彻底了解人脑的奥秘,也可无限地逼近。

Functional integration and the mind

Different cognitive functions recruit a number of different, often overlapping, areas of the brain. Theories in cognitive and computational neuroscience are beginning to take this kind of functional integration into account. The contributions to this special issue consider what functional integration tells us about various aspects of the mind such as perception, language, volition, agency, and reward. Here, I consider how and why functional integration may matter for the mind; I discuss a general theoretical framework, based on generative models, that may unify many of the debates surrounding functional integration and the mind; and I briefly introduce each of the contributions.     

情绪加工中杏仁核的效价特异性

杏仁核是情绪信息加工的关键脑区。近年来心理学和神经科学领域发现了杏仁核情绪加工的效价特异性现象,并且整体存在左侧杏仁核对正性情绪、右侧杏仁核对负性情绪以及双侧杏仁核负性偏好的特异性趋势,且受到材料突出特征、个体差异、任务条件的调节。未来可进一步探索注意对杏仁核情绪效价特异性的调节作用,探究动态情绪刺激加工时杏仁核的活动特点,考察心理障碍患者加工负性情绪时的杏仁核激活模式,并确定杏仁核的效价特异性在思维、计划、决策等高级认知过程中的表现。     

What neuroimaging and brain localization can do, cannot do and should not do for social psychology

Interest in bridging social psychology and neuroscience has seen a significant upsurge. Much of this interest has centered on brain localization--the attempt to relate psychological events to locations of brain events. Although many articles have sought to localize brain activity that supports social behavior, scant attention has been paid to the specific methods to be used in integrating brain localization data into psychological theory. The authors describe 4 strategies psychologists can use to integrate brain localization data and psychological theory, and they consider whether social psychology presents special considerations in the use of these strategies. They conclude that brain localization offers a useful tool for some but not all problems in social psychology, and they discuss the types of problems for which it may and may not prove useful.     

Psychological constructionism and cultural neuroscience

Lindquist et al. argue that emotional categories do not map onto distinct regions within the brain, but rather, arise from basic psychological processes, including conceptualization, executive attention, and core affect. Here, we use examples from cultural neuroscience to argue that psychological constructionism, not locationism, captures the essential role of emotion in the social and cultural brain.     

近红外光学成像在社会认知神经科学中的应用

A simple technique to study embodied language processes: the grip force sensor

Research in cognitive neuroscience has shown that brain structures serving perceptual, emotional, and motor processes are also recruited during the understanding of language when it refers to emotion, perception, and action. However, the exact linguistic and extralinguistic conditions under which such language-induced activity in modality-specific cortex is triggered are not yet well understood. The purpose of this study is to introduce a simple experimental technique that allows for the online measure of language-induced activity in motor structures of the brain. This technique consists in the use of a grip force sensor that captures subtle grip force variations while participants listen to words and sentences. Since grip force reflects activity in motor brain structures, the continuous monitoring of force fluctuations provides a fine-grained estimation of motor activity across time. In other terms, this method allows for both localization of the source of language-induced activity to motor brain structures and high temporal resolution of the recorded data. To facilitate comparison of the data to be collected with this tool, we present two experiments that describe in detail the technical setup, the nature of the recorded data, and the analyses (including justification about the data filtering and artifact rejection) that we applied. We also discuss how the tool could be used in other domains of behavioral research.     

Introduction to the special section on social neuroscience: promise and caveats

This special issue of the Journal of Personality and Social Psychology: Attitudes and Social Cognition is devoted to theory and research at the interface of social psychology and neuroscience. The 5 empirical articles represent the theoretical and methodological breadth of issues considered by social neuroscientists. The methods span brain lesion work to neuroendocrinology to psychophysiological indicators of brain activity to functional magnetic resonance imaging indicators of brain activity. The remaining 2 articles consider explicitly some of the promises and pitfalls of social neuroscience; these authors, although noting the power of neuroscience methods, remind readers of the serious challenges posed in trying to examine the biological processes underlying or associated with social psychological phenomena. These articles help to reveal the richness of social neuroscience and the power of neuroscientific methods to address processes and mechanisms that would not be possible with traditional social psychology methods.     

Neuroscience, Neuropolitics and Neuroethics: The Complex Case of Crime, Deception and fMRI

Scientific developments take place in a socio-political context but scientists often ignore the ways their innovations will be both interpreted by the media and used by policy makers. In the rush to neuroscientific discovery important questions are overlooked, such as the ways: (1) the brain, environment and behavior are related; (2) biological changes are mediated by social organization; (3) institutional bias in the application of technical procedures ignores race, class and gender dimensions of society; (4) knowledge is used to the advantage of the powerful; and (5) its applications may reinforce existing structures of power that pose ethical questions about distributive justice. The case of crime, deception and functional Magnetic Resonance Imaging (fMRI) shows the complexity, and the political and ethical challenges that confront those who seek to use neuroscience to explain the etiology of crime, and who base policy on its findings. An ethically grounded neuroscience needs to take account of existing structures of power and difference, and to develop a public neuropolitical consciousness that ensures that those subject to risk by the application of science and technology are participants in the decision-making processes involving the implementation of policies that affect them.     

Retrograde amnesia: forgetting back

Recently, the field of animal memory research has seen a resurgence of interest in the mechanisms underlying retrograde amnesia (RA) and in the use of RA as a technique for studying memory processes. A recent report from a major neuroscience lab, which demonstrated RA for an old reactivated memory, revitalized the debate regarding the widely accepted memory-consolidation theory of RA. Here, we discuss a number of the characteristics of RA and consider the findings that led to the development of the memory-consolidation hypothesis, as well as those suggesting an alternative retrieval-deficit explanation.     

人们为什么会羞怯：认知机制及神经基础

羞怯指个体在社交情境下的抑制, 是个体参与社交的阻碍。近年来, 关于羞怯的认知神经科学研究增多, 学者基于元认知模型、社会适应模型、侧化脑-体情绪模型等理论, 探讨了大脑结构和功能以及几种与感知觉和注意相关的ERP成分与羞怯的关系。但当前关于羞怯认知神经科学的理论和实证研究尚处于起步阶段。基于上述提出羞怯的心理发展模型; 未来应从人格和情绪双角度研究羞怯, 并在开发研究范式的基础上, 加大羞怯认知神经机制的探讨。     

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.     

The emotional self: Embodiment,reflexivity, and emotion regulation

Current dominant trends in the biological and psychological sciences tend to put emphasis on the role of the brain, cognition, and consciousness in realising emotional states and attempting to regulate them. In this article, I suggest an alternative approach with the idea that emotions emerge within social relations and give meaning and value to the situations in which we are located. Humans are understood as embodied emotional selves for who thought and emotion are intertwined. However, individuals can get caught in obsessive and compulsive thinking and feeling traps where the self loses touch with its emotions, and because of this also loses contact with the social situation and the ability to skilfully navigate it. In such circumstances, the self gets overwhelmed by emotion and loses its poise in the social setting. I consider Buddhist meditation as a technique through which people can develop a more reflexive emotional self, where reflexivity is not about control of emotion but owning one's feelings and being able to respond more sensitively and skilfully in various situations.
