This study investigated endogenous and exogenous predictors of early literacy in Turkish-speaking children. Whether children's language and working memory performances (as the endogenous factors) and home literacy environment (as the exogenous factor) in the beginning of kindergarten predict the children's current and year-end early literacy…

The two major determinants of reading comprehension are language comprehension and decoding, but prior studies of the development of reading comprehension from an early age show inconsistent results. To clarify these inconsistencies we report a 6-year longitudinal study (starting at Age 4 years) where we control for measurement error and track the…

A collection of cognitive, linguistic, and spelling measures were administered to third-grade English L1 and L2 learners. To capture formative assessments of children's developing mental graphemic representations (MGRs), spelling errors in isolation were subjected to analysis across three metrics: (1) Phonological constrained; (2)…

The genetic factor structure of a range of learning measures was explored in twin children, recruited in preschool and followed to Grade 2 ("N"?=?2,084). Measures of orthographic learning and word reading were included in the analyses to determine how these patterned with the learning processes. An exploratory factor analysis of the…

This article reviews research on working memory (WM) and its use in second language (L2) acquisition research. Recent developments in the model and issues surrounding the operationalization of the construct itself are presented, followed by a discussion of various methods of measuring WM. These methods include word and digit span tasks, reading,…
