Perceptual training has been argued to be a potential means to modify temporal sensitivity (the ability to detect a time-based discrepancy between two stimuli) with previous studies providing preliminary evidence that perceptual training can lead to increased temporal sensitivity. However, previous studies have not employed a control group and therefore cannot rule out the possibility that the observed effects are due to repeated completion of the task, rather than the training itself. Moreover, despite temporal sensitivity being suggested to be an important aspect of the sense of agency, the effects of perceptual training on the sense of agency have not been explored. Therefore, this study aimed to explore the effects of perceptual training on the sense of agency and replicate previously observed effects on temporal sensitivity while utilizing a more rigorous methodology. Given the existing literature, it was predicted that the sense of agency and temporal sensitivity will be enhanced following perceptual training. Temporal sensitivity was only weakly modified by perceptual training when compared to the control condition. Sense of agency was significantly modulated by perceptual training, over and above the control condition. This study's findings present novel evidence indicating that perceptual training can influence high-level processes such as the sense of agency and temporal sensitivity.
有人认为，感知训练是一种潜在手段，可用于改变时间敏感性（即检测两个刺激之间基于时间差异的能力），先前的研究提供了初步证据表明感知训练可提高时间敏感性。然而，先前的研究未设置对照组，因此无法排除所观察到的效果是由于重复完成任务，而非训练本身的可能性。此外，尽管时间敏感性被认为是能动感的一个重要方面，但感知训练对能动感的影响尚未得到探讨。因此，本研究旨在探讨感知训练对能动感的影响，并在采用更严格方法的同时，重复先前观察到的对时间敏感性的影响。鉴于现有文献，预计感知训练后能动感和时间敏感性将得到增强。与对照条件相比，感知训练对时间敏感性的改变很微弱。感知训练对能动感有显著调节作用，超过对照条件。本研究的结果提供了新的证据，表明感知训练可影响诸如能动感和时间敏感性等高级过程。
