The Rapid Automatized Naming (RAN) test involves rapidly naming sequences of items presented in a visual array. RAN has generated considerable interest because RAN performance predicts reading achievement. This study sought to determine what elements of RAN are responsible for the shared variance between RAN and reading performance using a series of cognitive tasks and a latent variable modelling approach. Participants performed RAN measures, a test of reading speed and comprehension, and six tasks, which tapped various hypothesised components of the RAN. RAN shared 10% of the variance with reading comprehension and 17% with reading rate. Together, the decomposition tasks explained 52% and 39% of the variance shared between RAN and reading comprehension and between RAN and reading rate, respectively. Significant predictors suggested that working memory encoding underlies part of the relationship between RAN and reading ability.
快速自动命名（RAN）测试涉及快速说出视觉阵列中呈现的项目序列。RAN引起了相当大的兴趣，因为RAN表现可预测阅读成绩。本研究旨在通过一系列认知任务和潜在变量建模方法，确定RAN的哪些元素导致了RAN与阅读表现之间的共同方差。参与者进行了RAN测量、阅读速度和理解测试，以及六项任务，这些任务挖掘了RAN的各种假设组成部分。RAN与阅读理解的共同方差为10%，与阅读速度的共同方差为17%。分解任务分别解释了RAN与阅读理解之间以及RAN与阅读速度之间共同方差的52%和39%。显著的预测因素表明，工作记忆编码是RAN与阅读能力之间部分关系的基础。
