How deeply does action influence perception? Does action performance affect the perception of object features directly related to action only? Or does it concern also object features such as colors, which are not held to directly afford action? The present study aimed at answering these questions. We asked participants to repeatedly grasp a handled mug hidden from their view before judging whether a visually presented mug was blue rather than cyan. The motor training impacted on their perceptual judgments, by speeding participants' responses, when the handle of the presented mug was spatially aligned with the trained hand. The priming effect did not occur when participants were trained to merely touch the mug with their hand closed in a fist. This indicates that action performance may shape the perceptual judgment on object features, even when these features are colors and do not afford any action. How we act on surrounding objects is therefore not without consequence for how we experience them.
行动对感知的影响有多深？行动表现是否仅会影响与行动直接相关的物体特征的感知？还是它也涉及诸如颜色等物体特征，而这些特征并不被认为能直接为行动提供便利？本研究旨在回答这些问题。我们要求参与者在判断视觉呈现的杯子是蓝色而非蓝绿色之前，反复抓取一个他们看不见的有把手的杯子。当呈现的杯子的把手在空间上与训练的手对齐时，运动训练通过加快参与者的反应，对他们的感知判断产生了影响。当参与者被训练只是握拳触摸杯子时，启动效应并未出现。这表明行动表现可能会塑造对物体特征的感知判断，即使这些特征是颜色且不能为任何行动提供便利。因此，我们对周围物体的行动方式并非不会影响我们对它们的体验。
