人类有“自由意志”的意识体验：我们觉得我们可以产生我们的行动，从而影响我们的环境。在这里，我们使用了知觉时间的有意行动和他们的感官后果作为一种手段来研究意识的行动。这些感知到的时间在有意识的意识中被吸引到一起，所以受试者感知到的自愿运动发生得晚，而他们的感官后果发生得早于他们实际发生的时间。大脑磁刺激引起的类似的不自主运动逆转了这种吸引效应。我们的结论是，中枢神经系统适用于一个特定的神经机制，以产生有意绑定的行动和他们的影响，在有意识的意识。
Humans have the conscious experience of 'free will': we feel we can generate our actions, and thus affect our environment. Here we used the perceived time of intentional actions and of their sensory consequences as a means to study consciousness of action. These perceived times were attracted together in conscious awareness, so that subjects perceived voluntary movements as occurring later and their sensory consequences as occurring earlier than they actually did. Comparable involuntary movements caused by magnetic brain stimulation reversed this attraction effect. We conclude that the CNS applies a specific neural mechanism to produce intentional binding of actions and their effects in conscious awareness.
