Central questions in the study of visual word recognition and developmental dyslexia are whether early lexical activation precedes and supports decoding (a dual-stage view) or not (dual-route view), and the locus of deficits in dysfluent reading. The dual-route view predicts early word frequency and length interaction, whereas the dual-stage view…

Quantifying the decoding difficulty (i.e., 'decodability') of text is important for accurately matching young readers to appropriate text and scaffolding reading development. Since no easily accessible, quantitative, word-level metric of decodability exists, we developed a decoding measure (DM) that can be calculated via a web-based scoring…

There are 26 letters in the English language. These letters, in various combinations, represent the 44 sounds in the language. Teaching students the basic letter-sound combinations gives them access to sounding out approximately 84% of the words in English print. There needs to be equal amounts of time need to be spent on teaching the meanings of…

The aim of this project was to develop an early reading intervention for children with Down syndrome based on the related behavioral phenotype. The intervention targeted learning of letter-sound correspondences, reading of decodable and high frequency words, and phonological awareness. We evaluated the feasibility and potential efficacy of the…

A study was conducted into the operation of an interactive-compensatory model of reading. Specifically, it examined the development of context-free word recognition skills, their role in contextual reading, and the degree to which one word recognition skill might compensate another. Four word factors were examined: (1) orthographic redundancy (the…
