Background: Letter knowledge is crucial in the first stages of reading development. It supports learning letter-sound mappings and the identification of the letters that make up words. Previous studies have investigated the longitudinal impact of early letter knowledge on children's further word reading abilities. This study employed an artificial…

Reading development involves several changes in orthographic processing. A key question is, "how does the coding of letters develops in children learning to read?" Masked priming effects of transposition and substitution primes have been taken to index the importance of letter position and identity coding. Somewhat contradicting results…

Research identifies the alphabetic principle as a vital step in literacy development and validates Nonsense Word Fluency (NWF) measures as early predictors of reading success. The purpose of this study was to determine whether the NWF assessment process used to measure the alphabetic principle is culturally valid for early elementary Hmong…
