Despite nearly 40 years of scientific theorizing about reading, the field remains fragmented with little progress toward unification. In this article, we (a) emphasize the privileged position of unified theories in all science, (b) compare the growth of theory in cognitive science and reading, (c) identify the phenomenal domain of a unified…

Elementary and middle school children were given a large battery of tests evaluating reading subskills and reading-related cognitive abilities. These measures were used to define latent representing skills and abilities believed to be important components of reading comprehension. Hypothesized relationships among these constructs were specified…

This study examines the relation of language arts instruction to students' letter-word reading skill growth from the beginning of 1st grade to the end of 2nd grade using cross-classified random effects models. Amounts of teacher-managed, code-focused instruction in 1st and 2nd grade each uniquely predicted students' letter-word reading skill…

Many children struggle to learn to read, and these difficulties can persist well into adulthood. To address this problem, researchers have investigated the processes that underlie reading. An informative body of work has thus identified basic skills (e.g., decoding, vocabulary knowledge) as necessary for successful reading. Researchers also have…

This study examines the longitudinal relations among early literacy experiences at home and children's kindergarten literacy skills, Grade 1 word reading and spelling skills, and Grade 4 reading comprehension, fluency, spelling, and reading for pleasure. Ninety French-speaking children were tested at the end of kindergarten and Grade 1, and 65…

This study examines individual growth rates in phonological awareness and letter-word identification skills over an academic year for 150 Latino English-language learners. In October, February, and June of their kindergarten year, participants completed standardized measures of phonological awareness skills. Before the second and third…

This study had two aims: first, to investigate how emerging reading and spelling are interlinked when children move up from preschool to primary school and, second, to examine the antecedents of these skills. The study is part of the Jyvaskyla Entrance into Primary School Study in which 196 children 5 to 6 years of age were followed up every half…

In this article, we discuss the use of eye movement data to assess moment-to-moment comprehension processes. We first review some basic characteristics of eye movements during reading and then present two studies in which eye movements are monitored to confirm that eye movements are sensitive to (a) global text passage difficulty, and (b)…

The five articles in this special issue are a blend of experimental and correlational approaches that exemplify advances in contemporary approaches to assessment of reading comprehension. They illustrate how inferences about reading comprehension are determined in part by the material presented for comprehending and the format that is used for…

Reading comprehension scores from the Wechsler Individual Achievement Tests, the Gates-MacGinitie Reading Test, and the Gray Oral Reading Test were examined in relation to measures of reading, language, and other cognitive skills that have been hypothesized to contribute to comprehension and account for comprehension differences. In a sample of 97…

In the influential "simple view of reading" (Gough & Tunmer, 1986), Reading Comprehension (R) = Decoding (D) x Linguistic Comprehension (C). To evaluate this model, this article explores the performance of 15-year-olds with severe reading delays. Results showed that D and C described reading comprehension better than D and verbal cognitive ability…

This study examines how rapid automatized naming (RAN) components-articulation time and pause time-develop from kindergarten to the end of first grade and how RAN components are related to different reading measures and to RAN total time. Sixty-two children were administered RAN tasks in kindergarten and at the beginning and end of Grade 1.…

This article is based on the presidential address I delivered at the 12th annual meeting of the Society for the Scientific Study of Reading, held in June 2005 in Toronto. I trace the development of my interest in instructional research in, first, beginning reading and, more recently, in comprehension, and I describe studies designed to improve the…

Recent theoretical advances in working memory guided analyses of cognitive measures in 122 children with dyslexia and their 200 affected biological parents in families with a multigenerational history of dyslexia. Both children and adults were most severely impaired, on average, in three working memory components- phonological word-form storage,…

We examined the validity of the comprehension component of the Gray Oral Reading Test (GORT; Wiederholt & Bryant, 1992, 2001) by assessing whether reading really is required to answer its questions. The extent to which GORT questions are passage independent was assessed by having participants answer them without reading the passages. Most…
