The present research studied the role of the non-executive and executive components of working memory in the detection of phonological, orthographical, and grammatical spelling errors. Before performing error detection tasks, undergraduate participants completed a battery of tasks to evaluate their non-executive (verbal and visuospatial storage)…

Students in grades 5-9 (N = 29) with specific learning disabilities (SLDs) (dysgraphia, dyslexia, or oral and written language learning disability, OWL LD) were asked to take notes and handwrite or type summaries of social studies texts about world geography and cultures that they read or heard.

Fifth-grade US students (n = 175) completed two writing tasks that invited or required morphological manipulation of words. We examined both accuracy and error, specifically errors in…

In this study we propose a classification system for spelling errors and determine the most common spelling difficulties of Greek children with and without dyslexia. Spelling skills of 542 children from the general population and 44 children with dyslexia, Grades 3-4 and 7, were assessed with a dictated common word list and age-appropriate…

Investigates the written syntax of 81 college-able individuals demonstrating a specific learning disability. Supports a control impairment hypothesis, predicting that sentence production errors will be of the same kind as found in the language of writers demonstrating no handicapping conditions. Investigates the correlation of specific cognitive…

Examines whether dual-route models of spelling account for the misspellings of Spanish children of different educational levels. Finds that second graders relied heavily on phonological mediation, whereas eighth graders seemed to use a lexical strategy, and fourth-grade children showed an intermediate pattern. Finds support for dual-route spelling…
