阅读技能的习得是人类认知发展过程中具有里程碑意义的重要过程。在神经层面上，一个新的功能网络在这段时间发展起来，因为孩子们通常会学会将口语中熟悉的声音与字母语言中不熟悉的字符联系起来，并最终获得书面单词的含义，从而为以后的阅读提供条件。成熟阅读网络的一个关键组成部分位于左枕颞叶皮层，被称为“视觉词形系统”（VWFS），在读者中表现出印刷敏感的激活。VWFS对打印的敏感性何时以及如何产生仍然是一个悬而未决的问题。在这项研究中，我们利用功能性磁共振成像（fMRI） （n = 16）和事件相关电位（ERP） （n = 32）在一项受控的纵向训练研究中证明了枕颞叶皮层对打印的敏感性的启动。打印灵敏度快(
The acquisition of reading skills is a major landmark process in a human's cognitive development. On the neural level, a new functional network develops during this time, as children typically learn to associate the well-known sounds of their spoken language with unfamiliar characters in alphabetic languages and finally access the meaning of written words, allowing for later reading. A critical component of the mature reading network located in the left occipito-temporal cortex, termed the "visual word-form system" (VWFS), exhibits print-sensitive activation in readers. When and how the sensitivity of the VWFS to print comes about remains an open question. In this study, we demonstrate the initiation of occipito-temporal cortex sensitivity to print using functional MRI (fMRI) (n = 16) and event-related potentials (ERP) (n = 32) in a controlled, longitudinal training study. Print sensitivity of fast (
