Perceived duration can be subject to deviations around the time of a voluntary action. Whether the mechanisms underlying action-induced visual duration effects are effector-specific or require a more generalized action-linked multimodal calibration with the transient visual system, however, is a question yet to be answered. Here, we investigate this using dynamic visual stimuli presented as contingent upon the execution of an arbitrarily associated voluntary manual response. Our results demonstrate that the duration of intervals with arbitrarily associated keypress–visual event pair is perceived as shorter than the duration in a pure visual condition, where the same stimuli are rather passively observed without the execution of a concurrent action. Whereas the control experiments show that motor memory and attention cannot explain the action-induced changes in perceived temporal features, action-induced changes in perceived speed are dissociated from those in perceived duration, and that the duration compression disappears using isoluminant or static stimuli, which together provide evidence that these two effects can be modulated in the motion-processing units, although via separate neural mechanisms.

感知持续时间可能会随着自愿行动的时间发生偏差。然而，动作诱导的视觉持续时间效应的机制是效应器特异性的，还是需要使用瞬态视觉系统进行更广义的动作相关多模态校准，这是一个有待回答的问题。在这里，我们使用动态视觉刺激来研究这一点，该刺激视执行任意关联的自愿手动响应而定。我们的结果表明，具有任意关联的按键-视觉事件对的间隔持续时间被认为比纯视觉条件下的持续时间短，在纯视觉条件下，相同的刺激在没有执行并发动作的情况下被相当被动地观察到。
