主动控制感是主动动作过程中产生的控制自身动作, 进而控制外部环境的主观体验。构成动作主动控制感的核心要素是主观意图与结果反馈。本研究试图通过操控这两个核心要素的不同属性, 借助脑磁图等技术, 探寻主动控制感在大脑额-顶为主的脑网络中前-后馈的作用方式及时空特异性标记, 并建构新的认知神经理论模型。这将有利于理解人类动作的产生及后效、为相关精神类疾病的临床诊断提供更加客观的参照标准。

关键词: 主动控制感, 主观意图, 结果反馈, 时间压缩


Sense of agency (SOA) refers to the feeling of controlling one's own actions and events in the external world through voluntary actions. Over the past two decades, SOA has increasingly attracted attention from researchers, and its cognitive neural mechanism is still a cutting-edge scientific problem in this field. There are two ways to measure SOA: explicit measurement (i.e., the explicit judgements of agency reported by individuals) and implicit measurement (i.e., sensory perception difference). Both the temporal binding effect and the sensory attenuation effect can be used as implicit measures for SOA. Intention of action and sensory feedback are two core components constituting the SOA. Intention of action is a conscious experience of determining or planning to initiate an action. Extinction and termination of intention can prospectively affect SOA. The valence of action outcome, the causal relationship between an action and its outcome, and the characteristics of the outcome may retrospectively affect the sense of agency. According to the Comparator Model, a copy of the action command contained in the subjective intention predicts the outcome before action. When comparing the predicted sensory outcome with the actual feedback of the action, the prediction error is zero, generating SOA. Evidence from cognitive neuroscience suggests that intention may be closely related to the activities in the supplementary and pre-supplementary motor areas, and the action outcome may be related to the activities of the posterior parietal cortex. This project will focus on the neural substrates underlying SOA, and explore the prospective way of intention and the retrospective way of outcome exerting on SOA by manipulating different attributes of two core components (i.e., subjective intention and action outcome). The magnetoencephalography technology, which is of high temporal and spatial resolution, is employed to extract the time-space characteristics of SOA at the fronto-parietal network in both the time windows of action-outcome and after-outcome. Elucidating the neural mechanism of SOA will contribute to our understanding of the generation and aftereffects of human actions, thus providing implications for demarcating behavioral responsibilities in moral and legal settings, and for diagnosing related mental diseases.
