Discrimination of reversible mirrored letters (e.g., d and b) poses a challenge when learning to read as it requires overcoming "mirror invariance," an evolutionary-old perceptual tendency of processing mirror images as equivalent. The present study investigated "when," in reading development, mirror-image discrimination…

Background: The role of morphological awareness for literacy development is non-controversial, but it is likely to depend on the characteristics of a specific orthography. Previous studies analysing the role of morphological awareness are mainly based on English samples; thus, it is unclear how generalisable these results are. In the current…

Although there is a growing research base on Arabic literacy development to inform our understanding of the factors that account for variability in word reading skill, the current body of research is limited by two major constraints. First, although several studies examine one or more early literacy constructs, we were able to locate only two…

We examined the longitudinal predictors of nonword decoding, reading fluency, and spelling in three languages that vary in orthographic depth: Finnish, Greek, and English. Eighty-two English-speaking, 70 Greek, and 88 Finnish children were followed from the age of 5.5 years old until Grade 2. Prior to any reading instruction, they were…
