The International Dyslexia Association definition of dyslexia was updated 20 years ago and has been referenced frequently in research and practice. In this paper, researchers from the Florida Center for Reading Research consider the components of the definition and make recommendations for revisions. These include recognizing the persistence of…

This 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…

The effects of psycholinguistic variables are critical to the evaluation of theories about the cognitive reading system. However, reading research has tended to focus on the impact of key variables on average performance. We report the first investigation examining variation in psycholinguistic effects across the life span, from childhood into old…

In 2007, the New Zealand Ministry of Education formally recognized the condition of dyslexia for the first time and has subsequently developed a working definition of the condition. The aim of this article is to draw on contemporary theory and research on reading development, reading difficulties, and reading intervention to describe what the…

Despite a history of reading or spelling difficulties, some adults attain age-appropriate spelling skills and succeed at university. We compared the spelling of 29 such high-functioning dyslexics with that of 28 typical students, matched on general spelling ability, and controlling for vocabulary and non-verbal intelligence. Participants wrote…

This current study introduced a new method to investigate the prevalence and correlates of significant imbalances in the relative accuracy with which eighth-graders read nonwords (e.g., "prauma") and exception words (e.g., "vaccine"). Substantial proportions of students showed imbalanced word-reading profiles, but these were…

Assesses some phonological tasks of well compensated, high-functioning dyslexics, aged 18, whose reading ability had improved to within one standard deviation of the normal population. Compares them with matched controls. Finds they performed well on word recognition tests but worse on nonword reading and spelling, and worse (in terms of speed) on…

Investigates whether asynchrony of speed of processing between visual-orthographic and auditory-phonological modalities can account for word recognition deficits among dyslexic readers. Indicates that dyslexic readers were slower than control readers in most of the experimental tasks. Proposes a theory suggesting that asynchrony between the…

Finds that a deficiency in phonological coding and an overreliance upon orthographic coding, often observed in dyslexic children, can also be seen in relatively poor readers and spellers within a normal adult population. (RS)

Comparison of the individual reading strategies of 26 severely impaired developmental dyslexics and 26 nonhandicapped readers found a distribution of skills and strategies over a continuum in both groups. Dyslexic students were specifically impaired in phonological processing, and half of them employed more whole-word oriented strategies than the…

Pseudoword (non-word) reading tasks are a commonly used measure of phonological processing across diverse fields of reading research. However, whether pseudoword reading gives any more information about phonological processing in young learner readers than does the reading of real words has seldom been considered. Here we show that pseudoword and…

Focusing on the process of reading comprehension, this book contains chapters on some central topics relevant to understanding the processes associated with comprehending text. The articles and their authors are as follows: (1) "Comprehension Processes: Introduction" (K. Rayner); (2) "The Role of Meaning in Word Recognition"…

Investigates word identification in Arabic and basic cognitive processes in reading-disabled (RD) and normal level readers of the same chronological age, and in younger normal readers at the same reading level. Indicates significant deficiencies in morphology, working memory, and syntactic and visual processing, with the most severe deficiencies…

Subjects measures of word recognition, phonological coding, and orthographic coding obtained from analyses of identical and fraternal twins to multivariate genetic analysis. Finds that genetic influences on individual differences in word recognition were more strongly related to genetic variance in phonological coding than in orthographic coding.…

Reports on a longitudinal study which revealed that dyslexic and normal children follow the same patterns in their use of (1) phonological and visual information for word recognition; (2) context to facilitate word recognition; and (3) phonological and visual information for spelling. (ARH)
