Visual perception appears to play an important role in Chinese reading development, and may be a factor limiting successful logographic reading acquisition for Chinese-speaking children with dyslexia. The aim of this study was to comprehensively profile visual perception, inclusive of motor-reduced visual perception (MRVP) and visual-motor…

Most current theories of reading and dyslexia derive from a relatively narrow empirical base: research on English and a handful of other European alphabets. Furthermore, the two dominant theoretical frameworks for describing cross-script diversity--orthographic depth and psycholinguistic grain size theory--are also deeply entrenched in Anglophone…

The visual complexity of orthographies varies across writing systems. Prior research has shown that complexity strongly influences the initial stage of reading development: the perceptual learning of grapheme forms. This study presents a computational simulation that examines the degree to which visual complexity leads to grapheme learning…

Through computational modeling, here we examine whether visual and task characteristics of writing systems alone can account for lateralization differences in visual word recognition between different languages without assuming influence from left hemisphere (LH) lateralized language processes. We apply a hemispheric processing model of face…

Bilingual reading can require more than knowing two languages. Learners must acquire also the writing conventions of their second language, which can differ in its deep mapping principles (writing system) and its visual configurations (script). We review ERP (event-related potential) and fMRI studies of both Chinese-English bilingualism and…

Dyslexia is a persistent problem in written language, consisting of a severe difficulty in word recognition. It is characterized by low reading performance, while other skills are not impaired, being normal or even superior in some cases. This paper reviews different proposals for defining and clarifying causes of dyslexia. Additionally, we…
