有意行为既涉及大脑运动区域的一系列神经事件，也涉及“我”是该行为作者的独特意识体验。本文探讨了这些神经事件和现象事件之间可能存在的联系。最近的运动预测模型与动作的意识经验及其神经控制有关。这些模型主要依赖于将运动的实际结果与其内部预测的效果相匹配。然而，我们对行动的有意识体验是否依赖于精确的匹配过程，还是依赖于“我”必须对某一特定事件负责的回顾性推断，目前尚不清楚。我们报告了一个实验，在这个实验中，正常受试者判断有意行为、无意识运动或这些行为的后续影响（听觉音调）的感知时间。我们发现，被试产生听觉音调的意图在被试动作的感知时间和音调之间产生了一种有意的联系。然而，如果意图被一个强加的无意识动作打断，然后是相同的音调，就不会发生这种绑定。意图行为的现象学要求在意图和效果之间建立一个适当的预测联系，而不是回顾性地推断是“我”导致了效果。(C) 2003 Elsevier Inc.版权所有。
Intentional action involves both a series of neural events in the motor areas of the brain, and also a distinctive conscious experience that "I" am the author of the action. This paper investigates some possible ways in which these neural and phenomenal events may be related. Recent models of motor prediction are relevant to the conscious experience of action as well as to its neural control. Such models depend critically on matching the actual consequences of a movement against its internally predicted effects. However, it remains unclear whether our conscious experience of action depends on a precise matching process, or a retrospective inference that "I" must have been responsible for a particular event. We report an experiment in which normal subjects judged the perceived time of either intentional actions, involuntary movements, or subsequent effects (auditory tones) of these. We found that the subject's intention to produce the auditory tone produced an intentional binding between the perceived times of the subject's action and the tone. However, if the intention was interrupted by an imposed involuntary movement, followed by the identical tone, no such binding occurred. The phenomenology of intentional action requires an appropriate predictive link between intentions and effects, rather than a retrospective inference that "I" caused the effect.
