The sense of agency is the sense that one is causing an action. A predictive account of the sense of agency proposes that sensory prediction based on efferent(motor) information plays a critical role in generating the sense of agency. An alternative hypothesis emphasizes a critical role for post-hoc inferential process in generating the sense of agency. According to this account, we experience the sense of agency when a thought appears in consciousness prior to an action, is consistent with the action, and is not accompanied by conspicuous other causes of the action. In this study, we divided the sense of agency into two layers ; non-conceptual and pre-reflective feeling of agency at the most basic level and conceptual and reflective judgment of agency at the more elaborated level. The results showed that sensory prediction rather than conceptual congruency between preview and action-effect contributed to the feeling of agency which was measured by sensory attenuation, whereas both processes contributed to the judgment of agency. Further experiments revealed that conceptual congruency received relatively higher weighting to judgment of agency when reliable forward model was not formed, whereas other cues of agency than sensory prediction received lower weighting when forward model could provide highly reliable cue. These results suggest that the judgment of agency is produced by weighting each source of information according to its reliability.

能动性的感觉是一个人正在引起一个行动的感觉。对能动感的预测性解释认为，基于传出（运动）信息的感觉预测在产生能动感中起着关键作用。另一种假设强调了事后推理过程在产生代理感中的关键作用。根据这一解释，当一个思想在行动之前出现在意识中，与行动一致，并且没有伴随着行动的其他明显原因时，我们就会体验到能动感。在这项研究中，我们将代理感分为两个层次：非概念性和前反思性的代理感在最基本的层面，概念性和反思性的代理判断在更详细的层面。结果表明，感觉预测，而不是概念之间的一致性预览和动作效果有助于代理的感觉，这是由感觉衰减测量，而这两个过程都有助于判断的代理。进一步的实验发现，当可靠的前向模型未形成时，概念一致性对能动性判断的权重相对较高，而当前向模型能提供高可靠性线索时，感觉预测以外的其他能动性线索的权重较低。这些结果表明，对代理的判断是通过根据其可靠性对每个信息来源进行加权而产生的。
