A unifying(聯(lián)合的) view of the basis（基礎(chǔ)） of social cognitionVittorio Gallese1, Christian Keysers1,2 and Giacomo Rizzolatti1Department系 of Neuroscience, Section章節(jié) of Physiology生理學(xué), University of Parma, ItalyBCN Neuroimaging神經(jīng)影像 Center, University of Groningen, Antonius Deusinglaan 2, Groningen, The NetherlandsIn this article we provide a unifying neural hypothesis on how individuals understand the actions and emotions of others. 在這篇文章中我們對(duì)個(gè)體是如何理解別人的行動(dòng)和感情的這一現(xiàn)象提供了一種聯(lián)合的神經(jīng)學(xué)的假設(shè)。Our main claim is that the fundamental基本的 mechanism機(jī)械裝置 at the basis of the experiential經(jīng)驗(yàn)的 understanding of others actions is the activation激活 of the mirror 鏡子neuron system. 我們的主要觀點(diǎn)是，用來(lái)理解別人的行為基本裝置是“mirror neuron system”（鏡像神經(jīng)系統(tǒng)）的激活.A similar mechanism, but involving the activation of viscero發(fā)動(dòng)機(jī)-motor centers, underlies在。之下 the experiential understanding of the emotions of others.理解別人的情感的基本裝置是一種相似的裝置，但它包含一個(gè)“viscera-motor centers”（ “內(nèi)臟發(fā)動(dòng)機(jī)中心”）。Humans are an exquisitely精致 social species物種. Our survival and success depends crucially至關(guān)重要的 on our ability to thrive茁壯成長(zhǎng) in complex social situations. One of the most striking突出的features of our experience of others is its intuitive憑直覺感知的 nature.This implicit含蓄的，不言說的 grasp抓住，領(lǐng)會(huì) of what other people do or feel will be the focus of our review回顧. We will posit假定 that, in our brain,there are neural mechanisms (mirror mechanisms) that allow us to directly understand the meaning of the actions and emotions of others by internally replicating復(fù)制 (simulat-simulating) them without any explicit明確的 reective mediation調(diào)解. 我們假定，在我們的腦中，有神經(jīng)裝置允許我們通過在沒有任何明確調(diào)解的前提下直接理解別人的行為的和情感的含義。Conceptual reasoning is not necessary for this understanding. 概念推理對(duì)于這種理解并不是必要的。As human beings, of course, we are able to reason about others and to use this capacity能力 to understand other peoples minds at the conceptual，declarative？聲明的 level. 作為人類，我們能夠推出別人（的行為或情感），我們當(dāng)然可以用這種能力在概念的、陳述的水平上來(lái)理解別人。Here we will argue, however, that the fundamental mechanism that allows us a direct experiential grasp of the mind of others is not conceptual reasoning but direct simulation模仿 of the observed events through the mirror mechanism. 然而，這里我們要提出的是，允許我們根據(jù)經(jīng)驗(yàn)的直接領(lǐng)會(huì)別人的心理活動(dòng)的重要裝置不是概念的推理，而是通過鏡像裝置對(duì)被觀察到的事件的直接模仿。 The novelty新穎性 of our approach（。的方法） consists in providing for the rst time a neurophysiological account解釋 of the experiential（經(jīng)驗(yàn)的0） dimension尺寸，度量 of both action and emotion understanding.我們的研究方法的新穎性包括：對(duì)依據(jù)經(jīng)驗(yàn)的對(duì)于行為和情感的理解首次提供了神經(jīng)科學(xué)上的解釋。What makes social interactions so different from our perception觀念 of the inanimate（使。沒有生命） world is that we witness目擊 the actions and emotions of others, but we also carry out拿出去similar actions and we experience similar emotions. 使得我們的社會(huì)互動(dòng)如此不同于我們對(duì)于無(wú)機(jī)世界的觀念的是，我們看到別人的行為和情感，但我們也采取相似的行為并且經(jīng)歷相似的情感。There is something shared分享的 between our rst- and third-person experience經(jīng)驗(yàn) of these phenomena: the observer and the observed are both individuals endowed資助的 with a similar brainbody腦-身 system. 在第一人稱視角的經(jīng)驗(yàn)與第三人稱視角的經(jīng)驗(yàn)之間有共通的部分：觀察者與被觀察者都在應(yīng)用一個(gè)相似的身心系統(tǒng)（mirror neuron system？）A crucial重要的 element元素 of social cognition is the brains capacity容量 to directly link the rst- 第一人稱and third-第三人稱person experiences體驗(yàn) of these phenomena (i.e. link I do and I feel with he does and he feels). 社會(huì)認(rèn)知的一個(gè)重要因素是這些現(xiàn)象中大腦將第一、第三人稱視角經(jīng)驗(yàn)聯(lián)系起來(lái)的能力。（例如，將我做和我想與他做和他想聯(lián)系起來(lái)）We will dene this mechanism裝置 simulation.模仿我們將這種裝置定義為模仿In the rst part of this review we will show that in the case of actions, simulation is based on a neural system responding回應(yīng) both when we execute處決 a particular goal-directed目標(biāo)導(dǎo)向的 action and when we observe someone else performing表現(xiàn)出 a similar action (mirror neuron system). 在第一部分我們將展示行為方面的案例，模仿基于神經(jīng)系統(tǒng)，在我們實(shí)際執(zhí)行目標(biāo)導(dǎo)向的行為以及我們觀察某人表現(xiàn)相似的行為時(shí)，它都會(huì)有回應(yīng)。In the second part, we will show that a similar mirroring mechanism, bridging？橋，連接 rst- and third-person experiences，also exists for emotions.第二部分，我們將展示，在情感方面也存在一個(gè)相似的裝置將第一第三視角經(jīng)驗(yàn)連接起來(lái)。Action understanding: cognitive and motor mechanisms 行為理解：認(rèn)知和發(fā)動(dòng)裝置The conventional依照傳統(tǒng)的 conceptual觀念的，概念的approach for understanding actions performed by others is to consider seen actions in a similar way to all other visual stimuli.傳統(tǒng)觀念中理解別人表現(xiàn)出的行為的方法就是按照與看待其他視覺刺激的方式相似的方式.Let us imagine a boy throwing stones into a river: the visual system describes the boy, the stone, the river, the movement of his arm, and the ying of the stones. The integration of all these separate elements produces the neural input to a central conceptual system that will interpret and assign meaning to the visual representation (e.g. see Fodor 1,2).讓我們想象In recent years, a different proposal提議 has been advanced提前了on how others actions can be understood. 近些年來(lái)，一種就“別人的行為何以被理解”的新的提議日趨高昂。This proposal is mostly based on the discovery of a set of neurons calledmirror neurons. 這種提議建立在對(duì)于鏡像神經(jīng)元的發(fā)現(xiàn)之上These neurons, originally found in the Ventral腹側(cè)的 Premotor（運(yùn)動(dòng)前區(qū)）cortex 皮層(area F5) of the macaque monkey（獼猴）,respond both when the monkey performs a particular goal-directed action, and when it observes another individual performing a similar action 3,4.這些神經(jīng)元，最初是在獼猴的前運(yùn)動(dòng)皮層腹側(cè)（F5區(qū)）發(fā)現(xiàn)的，這些神經(jīng)元在猴子執(zhí)行一種目標(biāo)導(dǎo)向的行動(dòng)以及當(dāng)它觀察里一個(gè)個(gè)體執(zhí)行相似的行動(dòng)時(shí)都會(huì)有所反應(yīng)。%Mirror neurons are a particular class of visuo-motor neurons, originally discovered in a sec-tor of the ventral premotor cortex of monkeys,called area F5 (REFS 10,11).Rizzolatti, G., Fadiga, L., Fogassi, L. & Gallese, V.%直方圖單位 縱坐標(biāo) spikes/s 尖峰放電 閃電強(qiáng)波 橫坐標(biāo) s（左至右增大）Figure 1.Example of a monkey F5 mirror neuron responding to action observation in full vision (a) and hidden (b) conditions. 例：一只猴子的f5鏡像神經(jīng)元在完全可以看到的條件下和部分內(nèi)容被隱藏的條件下對(duì)行動(dòng)觀察都有所反應(yīng)。The lower part of each panel illustrates the experimenters action as observed from the monkeys vantage point: 每個(gè)儀表板的較低部分暗示從猴子的優(yōu)勢(shì)眼觀察到的實(shí)驗(yàn)者的行動(dòng)。the experimenters hand starting from a fixed position, moving toward an object and grasping it (a,b), or mimicking grasping, also either in full vision(c) or hidden conditions (d). 實(shí)驗(yàn)者的手從一個(gè)固定位置開始，向一個(gè)物體移動(dòng)并且抓住它，或者模仿抓的動(dòng)作。這兩種都是在完全可以看到的條件下和部分內(nèi)容被隱藏的條件下進(jìn)行的。In these last two conditions the monkey observed the same movements as in (a) and (b), but without the target object. 在這些后面的兩種條件下，猴子觀察和a和b中同樣的運(yùn)動(dòng)，但是沒有目標(biāo)導(dǎo)向。The gray square on the right in (b) and (d) represents the opaque sliding screen that prevented the monkey from seeing the experimenters action performed behind it.

F5區(qū)的鏡像神經(jīng)元在猴子可以理解出現(xiàn)的行為的含義但沒有機(jī)會(huì)接觸可以顯著的引發(fā)f5區(qū)的視覺特征。在這兩項(xiàng)研究中，f5區(qū)鏡像神經(jīng)元是在猴子可以理解呈現(xiàn)的行為的含義的條件下進(jìn)行的，但沒有機(jī)會(huì)接觸可以顯著的激活f5區(qū)的視覺特征。If mirror neurons mediate調(diào)解 action understanding, one should also expect期待 their activation激活 in these conditions, reecting反映 the meaning含義of the observed action.如果鏡像神經(jīng)元調(diào)解行為理解，那么，就也應(yīng)該期待在這些條件下的他們的激活，這種激活反映了被觀察到的行為的含義。In the rst study, mirror neurons were tested in two conditions: in one, the monkey could see the entire action (e.g. a hand grasping action); in the other, the same action was presented but its nal critical part, that is the handobject interaction, was hidden by a screen (Figure 1).在第一項(xiàng)研究中，鏡像神經(jīng)元是在兩種條件下被測(cè)試的：其中一項(xiàng)中，猴子可以看見全部的行為（例如：一只手的“抓”動(dòng)作）；在另一項(xiàng)研究中，同一種行為被表現(xiàn)出來(lái)但是其最后的關(guān)鍵部分，是手物互動(dòng)被屏幕所隱藏了。Thus, in the hidden condition the monkey only knew that the object was present behind the screen. 所以，在隱藏條件下，猴子只是知道物體在屏幕后面。The results showed that more than half of the recorded neurons also responded in the hidden condition 5.結(jié)果顯示超過一半的被記錄的神經(jīng)元對(duì)于隱藏條件下的實(shí)驗(yàn)也有所反應(yīng)。In the second study, F5 mirror neurons were recorded when the monkey saw and heard executed執(zhí)行的 noisy actions (e.g. breaking peanuts, tearing sheets of paper apart), only saw, or only heard the same actions performed by another individual (Figure 2).Figure 2. Responses of two neurons selectively activated by action-related sounds (e.g. breaking peanuts, ripping paper).對(duì)與行為相聯(lián)系的聲音存在選擇性激活的兩種神經(jīng)元的反應(yīng)。（例如，砸花生，撕紙）Responses to two different actions for each neuron are shown, with the action triggering the most activation in blue. 所示的每種神經(jīng)元對(duì)不同行為的反應(yīng)，行為觸發(fā)了絕大部分藍(lán)色表示的激活。VCS, vision plus sound condition; V, vision-only condition; S, sound-only condition; M, motor condition, in which the monkey touched the object.

13, p. 185), expresses表達(dá) nicely the direct experiential understanding of the observed actions mediated（調(diào)解的） by the mirror mechanism.舉個(gè)例子，Merleau- Ponty對(duì)于它對(duì)于行為理解的意義的描述，很好的表達(dá)了直接的根據(jù)經(jīng)驗(yàn)的對(duì)于所觀察行為的經(jīng)由鏡像機(jī)制調(diào)解的理解。It is important to stress here that, in the present review, we discuss only how the meaning of action is understood and not how the intention of the actions agent is captured. 在這里強(qiáng)調(diào)一下是很重要的，在目前的回顧中，我們只是討論了行為的意義是如何被理解的，而不是行為的意圖是如何被識(shí)破的。Although we are inclined to believe that simulation probably underlies intention understanding(see 1421) too, this issue is outside the aim of the present review.盡管我們傾向于認(rèn)為模擬大概也在對(duì)于意圖的理解之下，這個(gè)話題確實(shí)在目前的回顧的目標(biāo)之外。Emotion understanding 情感理解So far, we have discussed the neural mechanism underlying action understanding. 至今為止，我們已經(jīng)討論了行為理解之下的神經(jīng)裝置。Does a similar mechanism mediate our understanding of the emotions of others?是否存在一個(gè)相似的裝置調(diào)節(jié)我們對(duì)于他人情感的理解呢？ In the next sections we will show that a similar mechanism is also involved in our capacity to understand and experience the emotional states of others. 在下一部分，我們將會(huì)展示一個(gè)在我們的能力中也有相似的裝置來(lái)理解和體驗(yàn)別人的情感情形。We will focus on the emotion of disgust, for which rich empirical（經(jīng)驗(yàn)的） evidence has recently been acquired（掌握了）. 我們將會(huì)關(guān)注厭惡情感，因?yàn)獒槍?duì)這種情感的經(jīng)驗(yàn)證據(jù)已經(jīng)被掌握了。 We will discuss in particular the role of the insula(腦島) that appears to play a fundamental role in the feeling and understanding of this basic emotion (see Box 1).我們將特別討論在感覺和理解基本情感過程中發(fā)揮重要作用的腦島。Box 1. Amygdala midl, insula, and selectivity for particular emotions表格1.杏仁核，腦島，對(duì)于特定情感的選擇性In this review we focus on the role played by the insula in the perception and experience of disgust. 在這片回顧里，我們將集中精力于腦島在厭惡情感的知覺與體驗(yàn)中發(fā)揮的作用。Many authors have emphasized a major role played by the amygdala in the perception and experience of fear (e.g. 64). 許多作者都強(qiáng)調(diào)過杏仁核在恐懼情感的知覺與體驗(yàn)中發(fā)揮的作用。Phillips et al. 47 found activations of amygdala as well as of the insula insjul to fearful versus neutral faces, and of the insula but not of the amygdala for disgusted versus neutral facial expressions. Phillips et al.發(fā)現(xiàn)杏仁核的激活就像腦島在相對(duì)于帶有中性表情的臉對(duì)帶有恐懼表情臉表現(xiàn)出激活一樣，而腦島的激活并不像杏仁核在相對(duì)于帶有中性表情的臉對(duì)于帶有厭惡表情的臉的激活一樣。Zald 46 reviewed the functional imaging literature on the amygdala and showed that although fearful facial expressions are the most robust rubst elicitors of amygdala activation,other facial expressions, including disgust, often also activate it. Zald 46回顧了對(duì)于杏仁核的功能性成像的文獻(xiàn)，表明，盡管“恐懼”面部表情是杏仁核激活的最強(qiáng)大的激發(fā)子，其他面部表情，包括“厭惡”表情，也能激活它。This last nding was not conrmed by our data 55. 最后一項(xiàng)發(fā)現(xiàn)尚未為我們的數(shù)據(jù)所證實(shí)。This controversy is probably due to the fact that the amygdala is a complex structure,containing medial nuclei that are involved in olfactory lfktri processing, and lateral ltrl nuclei that appear more selectively involved in the visual and auditory processing of threat 65. 這種爭(zhēng)論大概要?dú)w咎于杏仁核是一個(gè)復(fù)雜的結(jié)構(gòu)，包括中間的與嗅覺過程相關(guān)的核，側(cè)面的對(duì)視覺和聽覺威脅的過程表現(xiàn)出更大的選擇性的核。Given the susceptibility artifacts encountered in fMRI and the spatial limits of PET, it is difcult, if not hopeless,
