Reading predictors evolve through age: phonological awareness is the best predictor of reading abilities at the beginning of reading acquisition while Rapid Automatized Naming (RAN) becomes the best reading predictor in more experienced readers (around 9-10 years old). Those developmental changes in the relationship between RAN and reading have so far been explained in term of participants' age. However, it should be noted that in the previous experiments age always co-vary with participants reading level. It is thus not clear whether RAN-reading relationship is developmental in nature or related to the reading system itself. This study investigates whether the behavioral changes in the relationship between RAN and reading and their electrophysiological correlates are related to the chronological age or to the reading level of the participants. Thirty two French-speaking children aged 7-10 years took part to the experiment: they were divided into groups contrasted on age but with similar reading levels and the other way round. Participants performed two reading tasks and four RAN tasks. EEG/ERP was recorded during discrete letter and picture RAN. Behavioral results revealed that alphanumeric RAN is more sensitive to age variations than reading level differences. The inverse profile was revealed for picture RAN, which discriminate poor and good readers among typically developed children within the same age-group. ERPs of both letter and picture RAN differed across age groups whereas only for the picture RAN ERPs differed across reading levels. Taken together, these results suggest that picture RAN is a particularly good indicator of reading level variance independently of age.
语音意识是阅读习得开始时阅读能力的最佳预测指标，而快速自动命名（RAN）则成为经验更丰富的读者（约9至10岁）中最佳的阅读预测指标。到目前为止，RAN与阅读之间关系的这些发展变化一直是根据参与者的年龄来解释的。然而，应该注意的是，在之前的实验中，年龄总是与参与者的阅读水平共同变化。因此，尚不清楚RAN与阅读之间的关系本质上是与发育有关还是与阅读系统本身有关。本研究调查了RAN与阅读之间关系的行为变化及其电生理相关性是与实际年龄还是与参与者的阅读水平相关。32名7至10岁的法语儿童参与了实验：他们被分成年龄不同但阅读水平相似的组，反之亦然。参与者完成了两项阅读任务和四项RAN任务。在离散字母和图片RAN过程中记录脑电图/事件相关电位（EEG/ERP）。行为结果显示，字母数字RAN对年龄变化比阅读水平差异更敏感。图片RAN则呈现相反的情况，它能在同一年龄组的典型发育儿童中区分阅读能力差和阅读能力好的读者。字母和图片RAN的ERP在不同年龄组之间存在差异，而仅图片RAN的ERP在不同阅读水平之间存在差异。综合来看，这些结果表明图片RAN是一个特别好的阅读水平差异指标，与年龄无关。
