Abstract / Summary: 

Purpose. The purpose of this longitudinal study is to investigate how Rapid Automatized Naming (RAN) develops over time, and how RAN contributes to reading. The development of non-alphanumeric RAN (objects) and alphanumeric RAN (numbers and letters) were investigated in preschool and early schoolyears, before and during formal reading instruction. Method. In this study children (n=364) were assessed on RAN measures when children were 4 (t1), 6 (t2), 8 (t3) and 9 (t4) years old. At t1 and t2, the assessment included non-alphanumeric RAN tasks, and at t3 and t4 both non-alphanumeric and alphanumeric RAN tasks were included. Latent growth curve analyses were computed and relations within and between the various RAN tasks were examined, as well as their relations to reading. Results. The results indicate that RAN is consistent over time, and non-alphanumeric RAN predicts later alphanumeric RAN. Alphanumeric RAN and non-alphanumeric RAN both predict basic word decoding. Alphanumeric RAN, but not non-alphanumeric RAN, predicts more complex orthographic reading and non-word reading. Conclusions. These results imply that both non-alphanumeric RAN and alphanumeric RAN are valid predictors of early phases of word decoding. Alphanumeric RAN is also a valid predictor of more complex reading, whereas non-alphanumeric RAN is not.
