This study investigated which components of the writing production process are impaired in Spanish children with developmental dyslexia (DD) aged 8 to 12 years. Children with and without dyslexia (n = 60) were assessed in their use of the lexical and the sublexical routes of spelling as well as the orthographic working memory system by…

Spelling errors are usually studied in dictations, but teachers report that children with school difficulties often make spelling mistakes when they copy a text too. The present study examines the performance on a text copying task and a text dictation task of two groups of children known for their difficulties in spelling, that is, 22 with…

The purpose of this study was to explore the nature of spelling errors made by children with dyslexia in Bosnian language with transparent orthography. Three main error categories were distinguished: phonological, orthographic, and grammatical errors. An analysis of error type showed 86% of phonological errors, 10% of orthographic errors, and 4%…

Spelling is a prerequisite to expressing vocabulary in writing. Research has shown that children with dyslexia are hesitant spellers when composing. This study aimed to determine whether the hesitant spelling of children with dyslexia, evidenced by frequent pausing, affects vocabulary choices when writing. A total of 31 children with dyslexia,…

In this study we focused on the spelling of high-functioning students with dyslexia. We made a detailed classification of the errors in a word and sentence dictation task made by 100 students with dyslexia and 100 matched control students. All participants were in the first year of their bachelor's studies and had Dutch as mother tongue. Three…

Spelling error patterns of 30 disabled readers (grades 3 through 6) were compared to error patterns of 40 younger able readers (grades 1 through 3), and 37 able readers of the same age. Discriminant analyses indicated distinguishing patterns, primarily between the disabled readers and the older able readers. (Author/SEW)

Two studies involved 21 reading disabled elementary students grouped as either dysphonetics (characterized by nonphonetic spelling errors) or dyseidetic readers (characterized by spelling words according to sound rather than appearance). Cognitive strategy differences were noted in visual sequential memory. Findings emphasized the importance of an…

A study of Hans Christian Andersen's diaries from age 20 to age 70 found that his mean error spelling percentages are equal to contemporaries, but between 2 and 15 times lower than individuals with dyslexia. A structural analysis indicates that the proportion of plausible/implausible errors match those of normal achievers. (Contains references.)…

The article explores information processing models of spelling performance and argues that an adequate theory of spelling processes must include: (1) qualitative changes in performance as a function of maturation that underlie development of automaticity; (2) transactional development of spelling-related knowledge structures and efficient…
