A rapid, alternating stimulus (RAS) naming measure was designed to study the developing ability in dyslexic readers to direct attention to contextual patterns while performing a rapid serial naming task. The results from a 3-year longitudinal investigation of 98 children indicate three trends. RAS performances differentiate both average from impaired readers and dyslexic subgroups from each other. The largest, most impaired subgroup can not complete the RAS tasks in kindergarten; the smaller subgroups have little name access speed deficits. Early RAS performances are highly predictive of later reading, particularly at the single-word reading level. Implications for understanding the development of automaticity and the relationship between retrieval speed and reading are discussed.
设计了一种快速交替刺激（RAS）命名测量方法，以研究阅读障碍读者在执行快速序列命名任务时，将注意力引导至上下文模式的发展能力。对98名儿童进行的为期3年的纵向调查结果显示出三个趋势。RAS表现既能区分普通读者与阅读障碍读者，也能区分阅读障碍亚组。规模最大、障碍最严重的亚组在幼儿园阶段无法完成RAS任务；规模较小的亚组在命名获取速度方面几乎没有缺陷。早期的RAS表现对后期阅读具有高度预测性，尤其是在单字阅读水平上。文中讨论了这对于理解自动化发展以及检索速度与阅读之间关系的意义。
