Two studies were carried out in order to better understand the role of perceptual and visuo-motor skills in handwriting. Two training programs, visual-haptic (VH) and visual (V), were compared which differed in the way children explored the letters. The results revealed that improvements of VH training on letter recognition and handwriting quality were higher than improvements after V training. We suppose that VH training was more efficient because it improved both perceptual and visuo-motor skills. In the second experiment, in order to investigate the part of each component, we assessed the link between visuo-motor skills, perceptual skills and handwriting. The results showed that only the visuo-motor tasks predict handwriting copying performance. These results are discussed in relation to the respective roles of the perceptual and visuo-motor skills on letter shape learning and handwriting movement execution.
两项研究旨在更好地理解知觉和视动技能在手写字中的作用。比较了两种训练方案，即视觉-触觉（VH）和视觉（V），它们在儿童探索字母的方式上有所不同。结果表明，VH 训练在字母识别和书写质量方面的提高高于 V 训练。我们假设 VH 训练更有效，因为它同时提高了知觉和视动技能。在第二项实验中，为了研究每个组成部分的作用，我们评估了视动技能、知觉技能和书写之间的联系。结果表明，只有视动任务可以预测书写复制表现。这些结果与知觉和视动技能在字母形状学习和书写运动执行中的各自作用有关。
