A new perspective is described which views developmental dyslexia as the outcome of learning to write the alphabet in the nondominant (right) hemisphere. The letter-level and whole-word subtypes of dyslexia are seen as differing responses adopted to cope with this predicament. Striking similarities between dyslexics and callosotomy patients in the allocation of covert attention to lateralized stimuli provide direction for integrating a diversity of dyslexic research within this framework. This synthesis, together with information from pure alexia, brain activation, and reading research, lends insight into the neural circuitry of the compensatory strategies adopted by the two dyslexic subtypes.
本文描述了一种新观点，即把发展性阅读障碍视为在非优势（右）半球学习书写字母表的结果。阅读障碍的字母水平亚型和整词亚型被视为应对这一困境所采取的不同反应。阅读障碍者与胼胝体切开术患者在对侧化刺激进行隐蔽注意分配方面的显著相似性，为在这一框架内整合各种阅读障碍研究提供了方向。这种综合，连同来自纯失读症、脑激活和阅读研究的信息，有助于深入了解两种阅读障碍亚型所采用的补偿策略的神经回路。
