Abstract

Fast and accurate visual recognition of single characters is crucial for efficient reading. We explored the possible contribution of writing memory to character recognition processes. We evaluated the ability of adults to discriminate new characters from their mirror images after being taught how to produce the characters either by traditional pen-and-paper writing or with a computer keyboard. After training, we found stronger and longer lasting (several weeks) facilitation in recognizing the orientation of characters that had been written by hand compared to those typed. Functional magnetic resonance imaging recordings indicated that the response mode during learning is associated with distinct pathways during recognition of graphic shapes. Greater activity related to handwriting learning and normal letter identification was observed in several brain regions known to be involved in the execution, imagery, and observation of actions, in particular, the left Broca's area and bilateral inferior parietal lobules. Taken together, these results provide strong arguments in favor of the view that the specific movements memorized when learning how to write participate in the visual recognition of graphic shapes and letters.

摘要

对单个字符进行快速准确的视觉识别对于高效阅读至关重要。我们探究了书写记忆对字符识别过程可能产生的影响。在教导成年人如何通过传统的纸笔书写或电脑键盘来书写字符之后,我们评估了他们区分新字符与其镜像的能力。训练后,我们发现与打字相比,手写字符的方向识别得到了更强且更持久(数周)的促进。功能磁共振成像记录表明,学习过程中的反应模式与图形形状识别过程中的不同通路相关。在几个已知参与动作执行、想象和观察的脑区,特别是左侧布洛卡区和双侧下顶叶小叶,观察到了与手写学习和正常字母识别相关的更强活动。综上所述,这些结果有力地支持了这样一种观点,即学习书写时记忆的特定动作参与了图形形状和字母的视觉识别。
