自我能动性是一种体验，即成为自己思想和运动行为的代理人。自我能动性的完整体验对于与外部世界的成功互动是必要的（即，现实监视）和用于响应我们的运动动作的感觉反馈（例如，语音反馈控制）。现实监控是区分内部自我生成的信息和外部现实（外部派生的信息）的能力。在本研究中，我们考察了自我能动性与低水平言语反馈监控（即，监控我们听到自己说什么）和更高层次的认知现实监控任务。特别是，我们研究了言语反馈监测和现实监测是否是由体验自我代理的能力驱动的-对自我产生的行动的结果做出可靠预测的能力。在现实监控任务中，受试者判断信息是先前自我生成的（自我代理判断）还是外部衍生的（外部代理判断）。在言语反馈监测过程中，我们通过改变环境听觉反馈来评估自我代理，以便受试者听他们自己的言语的扰动版本。当受试者在说话时听到听觉反馈中的最小扰动时，他们会做出纠正反应，这表明他们将扰动判断为语音输出中的错误。我们发现，在现实监控任务中，自我代理判断在听觉反馈的最小音高扰动期间具有较小纠正反应（p = 0.05）和较小试验间变异性（p = 0.03）的人中更高。这些结果提供了一个单一的过程的经验，自我机构管理低层次的语音控制和更高层次的现实监测的支持。
Self-agency is the experience of being the agent of one’s own thoughts and motor actions. The intact experience of self-agency is necessary for successful interactions with the outside world (i.e., reality monitoring) and for responding to sensory feedback of our motor actions (e.g., speech feedback control). Reality monitoring is the ability to distinguish internally self-generated information from outside reality (externally-derived information). In the present study, we examined the relationship of self-agency between lower-level speech feedback monitoring (i.e., monitoring what we hear ourselves say) and a higher-level cognitive reality monitoring task. In particular, we examined whether speech feedback monitoring and reality monitoring were driven by the capacity to experience self-agency—the ability to make reliable predictions about the outcomes of self-generated actions. During the reality monitoring task, subjects made judgments as to whether information was previously self-generated (self-agency judgments) or externally derived (external-agency judgments). During speech feedback monitoring, we assessed self-agency by altering environmental auditory feedback so that subjects listened to a perturbed version of their own speech. When subjects heard minimal perturbations in their auditory feedback while speaking, they made corrective responses, indicating that they judged the perturbations as errors in their speech output. We found that self-agency judgments in the reality-monitoring task were higher in people who had smaller corrective responses (p = 0.05) and smaller inter-trial variability (p = 0.03) during minimal pitch perturbations of their auditory feedback. These results provide support for a unitary process for the experience of self-agency governing low-level speech control and higher level reality monitoring.
