感知和行动几乎在日常生活的每时每刻都相互作用。先前的研究表明，不仅知觉输入塑造行动，而且与行动相关的各种因素，包括个人能力和生物力学成本，影响知觉决策。然而，目前还不清楚动作流畅性如何影响早期视觉感知的灵敏度，如方向。为了解决这个问题，我们使用了双任务范式：参与者准备了一个行动（例如，抓取），同时执行方向变化检测任务。我们证明，随着动作变得更加流畅（例如，随着抓握错误的减少），感知辨别性能也得到改善。重要的是，我们发现，抓培训之前的歧视增强随后的感知灵敏度，支持感知和行动之间的相互关系的概念。
Perception and action interact in nearly every moment of daily life. Previous studies have demonstrated not only that perceptual input shapes action but also that various factors associated with action-including individual abilities and biomechanical costs-influence perceptual decisions. However, it is unknown how action fluency affects the sensitivity of early-stage visual perception, such as orientation. To address this question, we used a dual-task paradigm: Participants prepared an action (e.g., grasping), while concurrently performing an orientation-change-detection task. We demonstrated that as actions became more fluent (e.g., as grasping errors decreased), perceptual-discrimination performance also improved. Importantly, we found that grasping training prior to discrimination enhanced subsequent perceptual sensitivity, supporting the notion of a reciprocal relation between perception and action.
