虽然以前的文献表明，写作练习促进了字母的神经专门化，但这种促进作用是由写作行为的知觉反馈驱动的，还是由运动行为的实际执行驱动的，目前还不清楚。本研究通过测量7岁儿童对手写字母、未学习的草书字母和草书字母的反应中粗体信号的变化来解决这个问题，这些字母是7岁儿童主动通过书写和被动地观察实验者书写而学习的。在识别草书和手稿形式的字母时，使用功能磁共振成像来评估大脑的激活情况。结果表明，主动训练导致与字母知觉相关的感觉-运动网络以及岛叶和屏状核的招募增加，但被动观察没有。这表明，新学习的草书字母的知觉网络是由运动执行而不是知觉反馈驱动的。
Although previous literature suggests that writing practice facilitates neural specialization for letters, it is unclear if this facilitation is driven by the perceptual feedback from the act of writing or the actual execution of the motor act. The present study addresses this issue by measuring the change in BOLD signal in response to hand-printed letters, unlearned cursive letters, and cursive letters that 7-year-old children learned actively, by writing, and passively, by observing an experimenter write. Brain activation was assessed using fMRI while perceiving letters—in both cursive and manuscript forms. Results showed that active training led to increased recruitment of the sensori-motor network associated with letter perception as well as the insula and claustrum, but passive observation did not. This suggests that perceptual networks for newly learned cursive letters are driven by motor execution rather than by perceptual feedback.
