The development of reading depends on phonological awareness across all languages so far studied. Languages vary in the consistency with which phonology is represented in orthography. This results in developmental differences in the grain size of lexical representations and accompanying differences in developmental reading strategies and the manifestation of dyslexia across orthographies. Differences in lexical representations and reading across languages leave developmental “footprints” in the adult lexicon. The lexical organization and processing strategies that are characteristic of skilled reading in different orthographies are affected by different developmental constraints in different writing systems. The authors develop a novel theoretical framework to explain these cross-language data, which they label a psycholinguistic grain size theory of reading and its development.

Reading acquisition, developmental dyslexia, and skilled reading across languages: a psycholinguistic grain size theory.

Emergent literacy consists of the skills, knowledge, and attitudes that are developmental precursors to reading and writing. This article offers a preliminary typology of children's emergent literacy skills, a review of the evidence that relates emergent literacy to reading, and a review of the evidence for linkage between children's emergent literacy environments and the development of emergent literacy skills. We propose that emergent literacy consists of at least two distinct domains: inside-out skills (e.g., phonological awareness, letter knowledge) and outside-in skills (e.g., language, conceptual knowledge). These different domains are not the product of the same experiences and appear to be influential at different points in time during reading acquisition. Whereas outside-in skills are associated with those aspects of children's literacy environments typically measured, little is known about the origins of inside-out skills. Evidence from interventions to enhance emergent literacy suggests that relatively intensive and multifaceted interventions are needed to improve reading achievement maximally. A number of successful preschool interventions for outside-in skills exist, and computer-based tasks designed to teach children inside-out skills seem promising. Future research directions include more sophisticated multidimensional examination of emergent literacy skills and environments, better integration with reading research, and longer-term evaluation of preschool interventions. Policy implications for emergent literacy intervention and reading education are discussed.

Child development and emergent literacy

We summarize some of the most important findings from research evaluating the hypothesized causes of specific reading disability (dyslexia) over the past four decades. After outlining components of reading ability, we discuss manifest causes of reading difficulties, in terms of deficiencies in component reading skills that might lead to such difficulties. The evidence suggests that inadequate facility in word identification due, in most cases, to more basic deficits in alphabetic coding is the basic cause of difficulties in learning to read. We next discuss hypothesized deficiencies in readingrelated cognitive abilities as underlying causes of deficiencies in component reading skills. The evidence in these areas suggests that, in most cases, phonological skills deficiencies associated with phonological coding deficits are the probable causes of the disorder rather than visual, semantic, or syntactic deficits, although reading difficulties in some children may be associated with general language deficits. Hypothesized deficits in general learning abilities (e.g., attention, association learning, cross-modal transfer etc.) and low-level sensory deficits have weak validity as causal factors in specific reading disability. These inferences are, by and large, supported by research evaluating the biological foundations of dyslexia. Finally, evidence is presented in support of the idea that many poor readers are impaired because of inadequate instruction or other experiential factors. This does not mean that biological factors are not relevant, because the brain and environment interact to produce the neural networks that support reading acquisition. We conclude with a discussion of the clinical implications of the research findings, focusing on the need for enhanced instruction.

Specific reading disability (dyslexia): what have we learned in the past four decades?

Phonological recoding and self-teaching: sine qua non of reading acquisition.

My research focused on literacy development in children through fourth grade and followed an earlier study (Juel, Griffith, & Gough, 1986). The Simple View of reading and writing received support in this earlier study and was examined in my current research. Of particular concern were these questions: Do the same children remain poor readers year after year? Do the same children remain poor writers year after year? What skills do the poor readers lack? What skills do the poor writers lack? What factors seem to keep poor readers from improving? What factors seem to keep poor writers from improving? The probability that a child would remain a poor reader at the end of fourth grade if the child was a poor reader at the end of first grade was .88. Early writing skill did not predict later writing skill as well as early reading ability predicted later reading ability. Children who became poor readers entered first grade with little phonemic awareness. By the end of fourth grade, the poor readers had still not achieved the level of decoding skill that the good readers had achieved at the beginning of second grade. Good readers read considerably more than the poor readers both in and out of school, which appeared to contribute to the good readers' growth in some reading and writing skills (e.g., in ideas for stories). Poor readers tended to become poor writers. The Simple View received support in accounting for reading and writing development through fourth grade. This study examined the development of literacy in one elementary school with a large minority, low socioeconomic status population. The reading and writing development of 54 children was followed as they progressed from first through fourth grade. This in-depth examination of literacy acquisition in a microcosm of at-risk children attempted to answer the following questions: Do the same children remain poor readers year after year? Do the same children remain poor writers year after year? What skills do the poor readers lack?
