Visual perception is not always veridical but can be influenced by factors such as ease of acting, energetic cost, and even body type of the observer. This notion is called action-specific perception. Several effects of action capability on visual perception have been found, but there is much controversy as to whether these effects are truly perceptual. Because perception cannot be measured directly, resolving the controversy relies on ruling out alternative explanations through systematic testing. We combined one of the most robust action-specific effects (the Pong effect) with one of the primary suggestions for exploring an alternative explanation, namely whether the effect persists across instructions that emphasize different aspects of the task. The Pong effect was robust to the type of instructions. The results provide critical evidence that the Pong effect is truly perceptual, furthering the argument that a person's ability to act can influence visual perception.
视觉感知并不总是准确的，但会受到易于行动、能量成本甚至观察者体型等因素的影响。这种概念被称为动作特异性感知。已经发现了动作能力对视觉感知的几种影响，但对于这些影响是否真的是感知性的，存在很大争议。由于无法直接测量感知，解决争议依赖于通过系统测试排除替代解释。我们将最强大的动作特异性效应之一（乒乓效应）与探索替代解释的主要建议之一结合起来，即该效应是否在强调任务不同方面的指令下仍然存在。乒乓效应不受指令类型的影响。研究结果提供了关键证据，表明乒乓效应是真正的感知性的，进一步证明了一个人的行动能力可以影响视觉感知。
