意向约束描述了行为及其效果被感知为时间近似的现象。我们在研究领域引入了一种新的持续时间估计方法--恒定刺激法。参与者自由选择按下两个键中的一个或经历被动按键。在250 ms或600 ms的间隔之后，出现视觉效果。在实验1中，每个键在特定的时间间隔后产生效果。在实验2中，两个键在相同的时间间隔后产生效果，这些时间间隔在会话之间变化。参与者将动作-效果间隔的持续时间与不同持续时间的音调进行比较。为了评估有意约束，我们比较了主动和被动条件之间的动作-效果间隔的感知持续时间。在两个实验中，我们都显示了600 ms的有意结合，但没有显示250 ms的作用-效果间隔。因此，恒定刺激的方法适合于评估有意结合。(C)2012 Elsevier Inc.

Intentional binding describes the phenomenon that actions and their effects are perceived to be temporally approximated. We introduced a new method of duration estimation to the research field, the method of constant stimuli. Participants freely chose to press one of two keys or experienced passive key presses. After an interval of 250 ms or 600 ms a visual effect occurred. In Experiment 1, each key produced an effect after a specific interval. In Experiment 2, both keys produced an effect after the same interval that varied between sessions. Participants compared the duration of the action-effect interval with a tone of varying duration. To assess intentional binding, we compared the perceived duration of the action-effect interval between the active and passive condition. We showed intentional binding for 600 ms, but not for 250 ms action-effect intervals in both experiments. Thus, the method of constant stimuli is suitable to assess intentional binding.
