A multi-dimensional framework for characterizing the role of writing system variation in literacy learning: a case study in Malayalam
AbstractMost children across the world learn to read and write in non-alphabetic orthographies such as abjads (e.g., Arabic), abugidas (e.g., Ethiopic Ge ’ez), and morphosyllabaries (e.g., Chinese). However, most theories of reading, reading development, and dyslexia derive from a relatively narrow empirical base of research in English—an outlier alphabetic orthography—and a handful of mainly Western European Roman alphabets. Consideration of t he full spectrum of the world’s writing systems reveals multiple dimensions of writing system complexity, each of which could possibly create obstacles for the developing re...

The Importance of the Left Occipitotemporal Cortex in Developmental Dyslexia
AbstractPurpose of ReviewDevelopmental dyslexia is characterized by an impaired acquisition of fluent and skilled reading ability. Numerous studies have explored the neural correlates of this neurodevelopmental disorder, with most classic accounts strongly focussing on left temporoparietal regions. We will review recent findings from structural and functional MRI studies that suggest a more important role of occipitotemporal cortex abnormalities in dyslexia.Recent FindingsRecent findings highlight the role of the occipitotemporal cortex which exhibits functional as well as structural abnormalities in dyslexic readers and i...

Measuring orthographic transparency and morphological-syllabic complexity in alphabetic orthographies: a narrative review
AbstractThis narrative review discusses quantitative indices measuring differences between alphabetic languages that are related to the process of word recognition. The specific orthography that a child is acquiring has been identified as a central element influencing reading acquisition and dyslexia. However, the development of reliable metrics to measure differences between language scripts hasn ’t received much attention so far. This paper therefore reviews metrics proposed in the literature for quantifying orthographic transparency, syllabic complexity, and morphological complexity of alphabetic languages. The review...

Phonological skills, visual attention span, and visual stress in developmental dyslexia.
In this study, we concurrently investigated 3 possible causes of dyslexia —a phonological deficit, visual stress, and a reduced visual attention span—in a large population of 164 dyslexic and 118 control French children, aged between 8 and 13 years old. We found that most dyslexic children showed a phonological deficit, either in terms of response accuracy (92.1% of t he sample), speed (84.8%), or both (79.3%). Deficits in visual attention span, as measured by partial report ability, affected 28.1% of dyslexic participants, all of which also showed a phonological deficit. Visual stress, as measured by subjective report...

Neurocognitive mechanisms of learning to read: print tuning in beginning readers related to word‐reading fluency and semantics but not phonology
This study demonstrates the presence of print tuning in the first year of reading acquisition and its development at the individual level. Moreover, individual differences in print tuning are not only related to word‐reading fluency, but also to semantic knowledge.
