中文摘要： 随着电脑和手机键盘输入法的盛行，“手写危机（即手写能力弱化）”现象愈加严重，儿童对文字的书写和感知能力越来越下降，通过“手写运动”促进儿童文字的视觉感知能力成为迫切的时代课题。“手写运动”是指用手产出各种文字图形数字等符号且能被感知的活动。其中，视觉感知技能是最基本的要素。本项目在前期研究基础上，以中国2-3年级儿童为主要研究对象，采集视觉感知的行为、ERPs及fMRI 数据，探讨手写运动促进中英文感知（简称“手写促进效应”）的认知神经机制。重点研究①集中和分散手写是否能促进文字的视觉感知；②设计文字和图形两种感知范畴，探讨手写促进效应的内在机理；③使用词汇和亚词汇两个层面，探讨手写促进效应的发生条件。最终将形成手写促进效应的跨语言普适性及语言特异性理论，揭示手写促进效应的认知机制、神经指标和脑区定位，进而为制定中国儿童书写能力提升计划提供理论基础。

英文摘要： With the prevalence of keyboard typewriting, the ignorance of handwriting causes “handwriting crisis”, which in turn desperates children’s writing development. There is an urgent call for enhancing the children’s handwriting ability. Visual perception skill is the basic for handwriting ability. Handwriting movement refers to a variety of categories and units of handwriting output, such as letters, graphics or numbers that can be perceived. Whether handwriting could facilitate perception is one of world’s cutting-edge research questions. The current proposal targets Chinese Grade 2-3 children who are at the critical period of handwriting development. Through the behavior，ERP-EEG and fMRI data, the proposal aims to explore cognitive and neural mechanism of the handwriting facilitating effect of English Words and Chinese characters in Children. Based on the previous studies of our research team, the project will continue investigating ①whether centralized or decentralized handwriting movement could facilitate the perception of Chinese characters and English letters; ②whether text or shape could enhance internal mechanism perception in Chinese or English ; ③using both words and sub-word dimensions, we will explore the conditions under which handwriting could promote the letter or character perception. The project will establish the language-general and language specific principles of the handwriting facilitating effect on the perception of English words and Chinese characters, revealing its cognitive mechanism, neural indicators and brain localization, and establishing theoretical foundations for the enhancement program of Chinese children's writing skills.
