The intentional binding effect refers to the phenomenon where the perceived temporal interval between a voluntary action and its sensory consequence is subjectively compressed. Prior research revealed the importance of tactile feedback from the keyboard on this effect. Here we examined the necessity of such tactile feedback by utilizing a touch-free key-press device without haptic feedback, and explored how initial/outcome sensory modalities (visual/auditory/tactile) and their consistency influence the intentional binding effect. Participants estimated three delay lengths (250, 550, or 850 ms) between the initial and outcome stimuli. Results showed that regardless of the combinations of sensory modalities between the initial and the outcome stimuli (i.e., modal consistency), the intentional binding effect was only observed in the 250 ms delay condition. This findings indicate a stable intentional binding effect both within and across sensory modalities, supporting the existence of a shared mechanism underlying the binding effect in touch-free voluntary actions.
意图绑定效应是指人们主观上感觉到的自愿行为与其感官后果之间的时间间隔被压缩的现象。先前的研究表明，键盘的触觉反馈对这种效应很重要。在这里，我们通过使用没有触觉反馈的无接触式按键设备来检验这种触觉反馈的必要性，并探索初始/结果感觉模态（视觉/听觉/触觉）及其一致性如何影响意图绑定效应。参与者估计初始刺激和结果刺激之间的三个延迟长度（250、550 或 850 毫秒）。结果表明，无论初始和结果刺激之间的感觉模态组合如何（即模态一致性），仅在 250 毫秒延迟条件下观察到意图绑定效应。这些发现表明，在无接触式自愿行为中，无论是在同一模态内还是跨模态，都存在稳定的意图绑定效应，支持绑定效应存在共享机制。
