The sense of agency is the experience of initiating and controlling one's voluntary actions and their outcomes. Intentional binding (i.e., when voluntary actions and their outcomes are perceived to occur closer together in time than involuntary actions and their outcomes) is increased in intentional action but requires no explicit reflection on agency. The reported experience of involuntariness is central to hypnotic responding, during which strategic action is experienced as involuntary. We report reduced intentional binding in a hypnotically induced experience of involuntariness, providing an objective correlate of reports of involuntariness. We argue that this reduced binding results from the diminished influence of motor intentions in the generation of the sense of agency when beliefs about whether an action is intended are altered. Thus, intentional binding depends on awareness of intentions. This finding shows that changes in metacognition of intentions affect perception.
能动性感知是指对自身主动行为及其结果的发起和控制的体验。意向绑定（即，当自愿行为及其结果在时间上被感知为比非自愿行为及其结果更接近时）在自愿行为中增加，但不需要对能动性进行明确的反思。报告的非自愿体验是催眠反应的核心，在催眠反应中，策略性行动被体验为非自愿的。我们报告了在催眠诱导的非自愿体验中，意向绑定的减少，为非自愿报告提供了一个客观的相关性。我们认为，这种绑定的减少是由于在生成能动性感知时，运动意图的影响减弱，而对行为是否有意的信念发生了改变。因此，意向绑定取决于对意图的意识。这一发现表明，对意图的元认知的变化会影响感知。
