Letters and numbers are different domains, and their differentiation increases with schooling. It has nonetheless been argued that reading alphabetic and numerical materials partly involves the same processes, even in adults. Whether individuals with dyslexia have difficulty reading and writing numbers remains to be established. This study…

Sequential regression was used to evaluate whether language-related working memory components uniquely predict reading and writing achievement beyond cognitive-linguistic translation for students in Grades 4 through 9 (N = 103) with specific learning disabilities (SLDs) in subword handwriting (dysgraphia, n = 25), word reading and spelling…

Programmatic, multidisciplinary research provided converging brain, genetic, and developmental support for evidence-based diagnoses of three specific learning disabilities based on hallmark phenotypes (behavioral expression of underlying genotypes) with treatment relevance: dysgraphia (impaired legible automatic letter writing, orthographic…

Syntax in the written expression of five normal and five learning disabled (LD) fourth graders was assessed. The syntax of the LD group was found to be significantly deficient when compared to that of the normal group. (Author)

The article examines two topics important to educators working with learning disabled college writers: error patterns of college learning disabled, normal, and basic writers across different tasks and instructional approaches successful in improvng the written language skills of college learning disabled writers, such as sentence combining and…

This article reviews the varied components of written language, suggest informal means for written language assessment, and summarizes the cognitive and linguistic factors that influence varied aspects of writing performance. Two informal evaluation scales are presented that stress the interconnection between oral and written language processes.…

The study analyzed communication performance of tenth grade learning disabled (LD) students (N=1,098) on the Florida State Student Assessment Test-II (a minimum competency test). LD students demonstrated better literal communication skills and poorer interpretive and written communication skills. Employers (N=240) also supported the importance of…

Four approaches to the investigation of connections between language by hand and language by eye are described and illustrated with studies from a decade-long research program. The four approaches support a model in which language by hand and language by eye are separate systems that interact in predictable ways. (Contains references.) (CR)

A study examined specific word- and sentence-level features most frequently used in the expository writing of 87 college students with learning disabilities, 50 with attention-deficit/hyperactivity disorder, 58 with both disabilities, and 92 controls. Very high correlations were found between verbosity, quality, and lexical complexity. (Contains…

This article introduces a special issue dealing with selected aspects of writing disorders. It provides an overview of following articles and issues confronting the written language field, including definitional issues, assessment issues, neurodevelopment components, brain-behavior linkages, lifespan issues, and interventions. Recommendations are…
