| 中文摘要 | The sense of agency is a subjective experience that an individual can control his or her own action and through which influences the environment during the preparation, execution and experiencing the result of an action. Exploring cognitive neural mechanisms of the sense of agency is of great significance in the fields of mental health, ethics and law, automatic driving, etc. It has been found that the sense of agency is influenced by prospective (e.g., intention, outcome expectation, etc.) or retrospective (e.g., outcome, etc.) effects. Scattered evidence for the neural mechanisms underlying the sense of agency was also provided. There is no neuroimaging study that systematically examines the neural mechanisms underlying prospective and retrospective effects on the sense of agency. Previous neuroimaging studies, limited by techniques, did not explore spatial and temporal characteristics for the neural basis underling the prospective or retrospective effect on the sense of agency at the same time. This study investigated the neural mechanisms underlying the effects of the intention and outcome on the sense of agency systematically, and explored the spatial and temporal characteristics of the neural mechanisms underlying prospective and retrospective effects on the sense of agency using magnetoencephalography and stereoelectroencephalography techniques. The neural mechanisms underlying the action binding and the outcome binding were explored separately. The theoretical model of the sense of agency was optimized based on the results of cognitive and neural mechanisms. Study 1 used two experiments to explore the neural mechanisms of the prospective effect of the intention on the sense of agency. In Experiment 1，magnetoencephalography was used to explore the activation patterns in the action-outcome window and the outcome onset window in voluntary pressing (with intention) and involuntary pressing (without intention) conditions. The neural mechanisms underlying the action binding and the outcome binding were also explored. The results of Experiment 1 showed that the neural mechanisms underlying the prospective effect of intention on the sense of agency included: the stimulus-preceding negativity in the right Pre-SMA and right SMA, the feedback-related negativity in the right MTG and left postcentral gyros, the β band oscillations in the right SMA, the γ band oscillations in the left postcentral gyros, and the connection between the left postcentral gyros and the right MTG. The action binding was found associated with the stimulus-preceding negativity in the right Pre-SMA and right SMA, and the y band oscillations in the left PCG. The outcome binding was found associated with the feedback-related negativity in the right MTG and left postcentral gyrus, the β band oscillations in the right SMA, and the connection between the left postcentral gyrus and the right MTG. The results reflect that prospective effect can affect both action-binding and outcome-binding effects, and the two possess different neural mechanisms. In Experiment 2, stereoelectroencephalography was used to re-examine the activation patterns in the action-outcome window and the outcome onset window in voluntary pressing and involuntary pressing conditions. The results of Experiment 2 showed that the right IFG, the region at which the right Pre-SMA locates, underlies the prospective effect of intention on the sense of agency. This result provided additional evidence for the essential role of the right Pre-SMA in the prospective effect of intention on the sense of agency. Study 2 aimed at exploring the neural mechanisms underlying the prospective effect of the outcome expectation and the retrospective effect of the outcome on the sense of agency. In Experiment 3, magnetoencephalography was used to explore the activation patterns in high outcome expectation and low outcome expectation conditions, and trials with the auditory stimulus as the outcome or without outcome. The results showed that the neural mechanisms underlying the prospective effect of outcome expectation on the sense of agency included: the feedback-related negativity in the right IPL，the low β band oscillations in the right IPL and the high β band oscillations in the left MTG. These neural activities were found associated with action binding. The bilateral connections between the right IPL and the left MTG were influenced by the outcome expectation. The neural mechanisms underlying the retrospective effect of outcome on the sense of agency included: the N1 in the right STG, the feedback-related negativity in the right OFC and the a band oscillations in the right STG. These neural activities were found associated with action binding. The bilateral connections between the right OFC and the right STG were influenced by the outcome. The findings reflect the ability of the prospective effect to influence the sense of agency in the absence of outcomes, as well as reveal that the outcome can influence the body agency of the sense of agency. This research investigated how the intention and outcome influence the sense of agency systematically. For the first time, the prospective effect and retrospective effect on the sense of agency have been separated in a functional neuroimaging study. This study explored the spatial and temporal characteristics of the neural mechanisms underlying prospective and retrospective effects on the sense of agency using magnetoencephalography and stereoelectroencephalography techniques, and optimized the theoretical model of the sense of agency based on the results of cognitive and neural mechanisms. This study is helpful for revealing the neural mechanisms of the sense of agency, and providing a theoretical basis for the application of the sense of agency in multiple fields. |
| 英文摘要 | 主动控制感是人类在动作的准备、执行以及结果反馈中产生的能够控制自身动作、并以此对外界环境产生影响的主观体验。研究主动控制感的认知神经机制在心理健康、道德法律、自动驾驶等领域具有重要的理论意义和应用价值。已有研究发现，主动控制感会受前馈(如，主动意愿、结果预期等)或后馈(如，动作结果等)的影响，并从时间或空间方面发现了一些主动控制感的认知神经机制线索。但是，以往研究尚未系统地探讨主动控制感受前馈和后馈影响的神经机制，而且囿于技术所限，未能同时考察前馈或后馈作用影响主动控制感的认知神经机制的时空特征。本研究运用脑磁图或立体定向脑电图技术完成了3个实验，系统地探讨前馈(主动意愿和结果预期)与后馈(动作结果)影响主动控制感神经机制的时空特征，探究主动动作一结果时间压缩效应(即内隐主动控制感)中动作绑定效应和结果绑定效应分别对应的神经表征，在认知机制和神经激活模式结果的基础上进一步优化主动控制感理论模型。 研究一通过两个实验探究了有结果且可预期条件下主动意愿的前馈作用涉及的主动控制感的认知神经机制。实验1采用脑磁图考察被试在主动按键(有主动意愿)与被动按键(无主动意愿)条件下的动作一结果时间窗和结果反馈时间窗内的神经激活模式，探究主动动作一结果时间压缩效应中动作绑定效应和结果绑定效应分别对应的神经表征。结果发现，主动意愿对主动控制感的前馈作用方式的神经表征有右前辅助运动区和右辅助运动区的刺激前负波、右颗中回和左中央后回的反馈负波，以及左中央后回到右颗中回的连接;时频表征有右辅助运动区的β频段与左中央后回的γ频段。其中，右前辅助运动区的刺激前负波、右辅助运动区的刺激前负波、左中央后回的γ频段和动作绑定效应相关;左中央后回的反馈负波、右颗中回的反馈负波、右辅助运动区的γ频段、左中央后回到右颗中回的连接和结果绑定效应相关。说明了前馈作用既能够影响动作绑定效应，也能够影响结果绑定效应，二者拥有不同的神经机制。实验2采用立体定向脑电图技术对被试在主动按键与被动按键条件下的神经激活模式进行验证，结果表明右前辅助运动区所在的右额上回的刺激前负波在主动条件与被动条件下的波幅差异趋势与脑磁图结果相似，进一步说明了右前辅助运动区的刺激前负波是主动意愿影响主动控制感的前馈作用方式的神经表征之一，为右前辅助运动区在动作意图影响主动控制感中的作用提供了重要的支持。 研究二探究主动动作条件下结果预期的前馈作用与结果有无的后馈作用涉及的主动控制感的认知神经机制。实验3采用脑磁图技术，通过操纵动作后声音刺激出现概率的高低，探究结果预期影响主动控制感的前馈作用方式及神经机制; 通过动作后声音刺激出现与否探究结果有无影响主动控制感的后馈作用方式及神经机制。结果发现，结果预期对主动控制感的前馈作用方式的神经表征有右下顶叶的反馈负波，在声音出现概率75%条件和50%概率条件下的无结果试次的差异波幅值与行为结果中的动作绑定效应相关;时频表征有右下顶叶的low γ频段和左颗中回的high β频段，频率差异与行为结果中的动作绑定效应相关;结果预期影响了右下顶叶与左颗中回的双向连接。结果有无对主动控制感的后馈作用方式的神经表征有右颗上回的N1和右眶额叶皮质的反馈负波，差异波幅值与行为结果中的动作绑定效应相关;时频表征有右颗上回的。频段，频率差异与行为结果中的动作绑定效应相关;结果有无影响了右眶额叶皮质与右颗上回的双向连接。研究结果反映了在动作后没有结果出现的条件下，前馈作用本身即能够影响主动控制感，以及揭示了动作结果的有无能够影响躯体控制感。 本研究综合探究了主动意愿、结果预期和结果有无这三个影响因素对主动控制感的影响方式，首次在脑成像研究中分离了前馈作用与后馈作用对主动控制感的影响，同时考察了前馈或后馈作用影响主动控制感的认知神经机制的时间特征和空间特征，在认知机制和神经激活模式结果的基础上进一步优化了主动控制感理论模型。本研究有助于深入揭示主动控制感的认知神经机制，为主动控制感在多领域的应用提供理论基础。 |
