我们调查的过程控制一个人的行动（“代理感”）的感觉。能动感可能取决于内部运动信号和对外部事件的一般推断。我们使用启动来调节自愿和非自愿运动的代理感，通过修改移动前有意识思维的内容。试验开始于两个阈上启动中的一个，这与参与者随后做出的自愿行动的效果相对应。运动和效果之间的感知间隔被用作代理感的内隐测量。启动调制知觉的时间间隔自愿和不自愿的运动，但调制是最大的不自愿的运动。第二个实验表明，这种调制依赖于启动运动（时间）的连续性。我们认为，机构的感觉是基于内部的运动信号和外部感官证据的来源的行动和效果的组合。(C)2009 Elsevier Inc. All rights reserved.
We investigate the processes underlying the feeling of control over one's actions ("sense of agency"). Sense of agency may depend on internal motoric signals, and general inferences about external events. We used priming to modulate the sense of agency for voluntary and involuntary movements, by modifying the content of conscious thought prior to moving. Trials began with the presentation of one of two supraliminal primes, which corresponded to the effect of a voluntary action participants subsequently made. The perceived interval between movement and effect was used as an implicit measure of sense of agency. Primes modulated perceived intervals for both voluntary and involuntary movements, but the modulation was greatest for involuntary movements. A second experiment showed that this modulation depended on prime-movement (temporal) contiguity. We propose that sense of agency is based on a combination of internal motoric signals and external sensory evidence about the source of actions and effects. (C) 2009 Elsevier Inc. All rights reserved.
