A number of cognitive factors have been suggested to underlie development in reading and arithmetic skills. Although the two domains are strongly linked, only a few studies have investigated the processes that are shared between them during the early school years. Rapid automatized naming (RAN) has been identified as a strong predictor of a common fluency factor in reading and arithmetic. In the current study with 232 Norwegian children, we examined how RAN in preschool and Grade 1 relates to the shared and nonshared variance in arithmetic fluency and reading fluency in Grade 3. Furthermore, we examined whether related processing skills (phoneme awareness, working memory, speed of processing, and symbol knowledge) can account for the relationship between RAN and shared fluency-or if they predict variance that is unique to each domain. Our results show that RAN in both preschool and Grade 1 is a strong predictor of shared variance between reading fluency and arithmetic fluency measured several years later, whereas other predictors mainly relate to the nonshared parts of variance in the fluency outcomes. That is, control variables with the theoretical potential to explain some of RAN's relation to the overlap between reading and arithmetic fluency do not in fact account for this relationship. Our findings provide a starting point for future investigations of the mechanisms of rapid naming.
一些认知因素被认为是阅读和算术技能发展的基础。尽管这两个领域密切相关，但只有少数研究调查了它们在早期学校阶段之间共享的过程。快速自动命名（RAN）已被确定为阅读和算术共同流畅性因素的强有力预测指标。在当前的研究中，我们对 232 名挪威儿童进行了研究，考察了学前和 1 年级的 RAN 与 3 年级的算术流畅性和阅读流畅性的共享和非共享方差之间的关系。此外，我们还考察了相关的加工技能（音素意识、工作记忆、加工速度和符号知识）是否可以解释 RAN 与共享流畅性之间的关系，或者它们是否可以预测每个领域独特的方差。我们的研究结果表明，学前和 1 年级的 RAN 是阅读流畅性和算术流畅性之间共享方差的有力预测指标，而其他预测指标主要与流畅性结果中的非共享方差部分有关。也就是说，具有理论潜力解释 RAN 与阅读和算术流畅性之间重叠关系的一些控制变量实际上并不能解释这种关系。我们的研究结果为未来对快速命名机制的研究提供了一个起点。
