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。

Sense of agency (SoA) refers to the feeling of controlling one᾽s own actions and, through them, events in the external world when performing voluntary actions. Intention of action and sensory feedback are two core components that constitute the sense of agency. However, the cognitive neural mechanism underlying the influence of these two components on SoA is unclear. We propose to explore the feedforward effect of action intention and the feedback effect of sensory feedback on SoA. The magnetoencephalography technology, which is of high temporal and spatial resolution, is employed to extract the time-space characteristics of sense of agency at the fronto-parietal network in both the time windows of action-outcome and after-outcome. The elucidation of this cognitive neural mechanism of SoA will contribute to our understanding of the generation and aftereffects of human actions; furthermore, it will provide implications for the demarcation of behavioral responsibilities in moral and legal settings, and for the clinical diagnoses of related mental diseases.
