自从布罗卡对语言处理进行研究以来，皮层功能专门化被认为是有效神经处理不可或缺的一部分。认知神经科学的一个基本问题涉及功能专业化发展所需的学习类型。为了解决字母神经专门化发展的问题，我们使用功能磁共振成像（fMRI）来比较学龄前儿童在不同字母学习条件之前和之后的大脑激活模式：感觉运动组在学习阶段练习打印字母，而对照组则练习视觉识别。结果表明，这些识字前的参与者在处理字母方面存在整体左半球偏向，但更有趣的是，仅在感觉运动（打印）学习后的字母感知过程中，视觉关联皮层的血氧水平依赖性激活增强。结论是，感觉运动体验增强了学龄前儿童视觉系统的处理能力。这些神经回路激活的变化提供了重要的证据，证明“边做边学”可以为用于视觉字母识别的神经系统奠定基础，并有可能加强该系统。
Since Broca's studies on language processing, cortical functional specialization has been considered to be integral to efficient neural processing. A fundamental question in cognitive neuroscience concerns the type of learning that is required for functional specialization to develop. To address this issue with respect to the development of neural specialization for letters, we used functional magnetic resonance imaging (fMRI) to compare brain activation patterns in pre-school children before and after different letter-learning conditions: a sensori-motor group practised printing letters during the learning phase, while the control group practised visual recognition. Results demonstrated an overall left-hemisphere bias for processing letters in these pre-literate participants, but, more interestingly, showed enhanced blood oxygen-level-dependent activation in the visual association cortex during letter perception only after sensori-motor (printing) learning. It is concluded that sensori-motor experience augments processing in the visual system of pre-school children. The change of activation in these neural circuits provides important evidence that ‘learning-by-doing’ can lay the foundation for, and potentially strengthen, the neural systems used for visual letter recognition.
