本研究采用干扰范式探讨了书写对字母视觉感知的影响。参与者画出形状和字母，同时视觉识别嵌入噪音中的字母和形状。实验1-3表明，字母知觉，而不是形状的知觉，受到运动干扰。这表明，对字母的感知与书写过程中所使用的神经基质之间存在密切联系。在类别（字母与形状）和感知相似性（直与弯曲）的特征看到的和画的项目确定干扰量的重叠。实验4表明，故意生产的字母是不必要的干扰发生，因为被动运动的手在字母的形状也干扰了字母的知觉。然而，当使用被动运动时，只有绘制项目的类别（字母与形状）而不是感知相似性产生了影响，这表明字母的运动表征可能通过本体感受反馈选择性地影响字母的视觉感知，并具有依赖于运动程序的感知相似性的额外影响。
We investigated how writing affects the concurrent visual perception of letters, using an interference paradigm. Participants drew shapes and letters while simultaneously visually identifying letters and shapes imbedded in noise. Experiments 1–3 demonstrated that letter perception, but not the perception of shapes, was affected by motor interference. This suggests a strong link between the perception of letters and the neural substrates engaged during writing. Both the overlap in category (letter vs. shape) and in the perceptual similarity of the features (straight vs. curvy) of the seen and drawn items determined the amount of interference. Experiment 4 demonstrated that intentional production of letters is not necessary for the interference to occur, because passive movement of the hand in the shape of letters also interfered with letter perception. When passive movements were used, however, only the category of the drawn items, (letters vs. shapes) but not the perceptual similarity, had an influence, suggesting that motor representations for letters may selectively influence visual perception of letters through proprioceptive feedback, with an additional influence of perceptual similarity that depends on motor programs.
