The relationships of different levels of phonological processing (sounds in heard and spoken words for whole words, syllables, phonemes, and rimes) to multi-leveled functional reading or writing systems were studied. Participants in this cross-sectional study were students in fourth-grade (n = 119, mean age 116.5 months) and sixth-grade (n = 105,…

Alternative models of the structure of individual and developmental differences of written composition and handwriting fluency were tested using confirmatory factor analysis of writing samples provided by first- and fourth-grade students. For both groups, a five-factor model provided the best fit to the data. Four of the factors represented…

We examined theoretical issues concerning the development of reading fluency and language proficiency in 390 English Language Learners (ELLs,) and 149 monolingual, English-as-a-first language (EL1) students. The extent to which performance on these constructs in Grade 5 (i.e., concurrent predictors) contributes to reading comprehension in the…

Third and fifth grade children (average age 8.6 and 10.6 years) and adult participants were tested with printed words of varying length in a new on-line identification task (the luminance increment paradigm, LIP) and a speeded naming task. Effects of general length (length in letters, phonemes and syllables) were shown to decrease systematically…
