Recent research has stated that early oral language acquisition difficulties are related to reading and writing difficulties. Children with developmental language disorder (DLD) experience difficulties with several dimensions of language. In this study we focus on the specific difficulties of children with DLD in spelling. We examine the impact of lexicality and length in written production of Spanish‐speaking children with DLD. A total of 18 children with language difficulties (Mage = 8;4) were compared with age‐matched children (Mage = 8;2). Participants completed a spelling‐to‐dictation task of words and pseudo‐words, where length was manipulated. A digital tablet was used to collect data and obtain measures of accuracy, latencies and total writing durations. Results showed that children with DLD produced more errors, longer latencies and longer writing durations than age‐matched children. Regarding accuracy, analysis of the errors shows that children in the control group produce few errors, most being substitutions, while children with DLD made more errors and of more varied categories. Moreover, they were more affected by length on writing accuracy than the control group. WHAT THIS PAPER ADDS: What is already known on this subject: Children with language difficulties are more likely to present reading difficulties. There are fewer studies analysing the impact of oral language difficulties in writing skills. What this paper adds to existing knowledge: The study suggests that children with oral language difficulties also have impairments in spelling, impacting on accuracy, duration and reaction time, possibly related to poor phonological working memory. What are the potential or actual clinical implications of this work?: This study highlights the need to emphasize early oral intervention and language‐related processing skills to help prevent written language difficulties.

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 manipulating lexical frequency, phonology-to-orthography (P-O) consistency, and word length in a copying task and a spelling-to-dictation task. Results revealed that children with dyslexia produced longer written latencies than chronological age-matched (CA) controls, more errors than CA and reading age-matched (RA) controls, and writing durations similar to CA controls. Latencies were more affected by frequency, consistency, and length in the DD group and the RA group than in CA controls. Children in the DD and RA groups produced longer written latencies in the copying than in the spelling-to-dictation task, while controls in the CA group were not affected by the task. Results indicate that spelling impairments in Spanish children with dyslexia affect the relative involvement of lexical and sublexical information during handwriting. Meanwhile, effects on writing speed seem to be related to deficits in reading ability, and accuracy scores seem to be poorer than expected by children's reading skill. [ABSTRACT FROM AUTHOR]

Abstract The impact of central on peripheral writing processes has been studied mainly in adults and children whose first language is a deep orthographic system. The results suggest that the influence varies according to age, but it also could depend on the orthographic system. The objective of the present work was to address the possible impact of the central (orthographic retrieval) on peripheral (motor execution) processes during writing acquisition in a transparent orthography. To achieve the objective, seventy-five Spanish children performed a copying and a spelling-to-dictation task, where orthographic consistency, lexical frequency and word length were manipulated. The results suggest that the central processes influence the peripheral ones from an early age (when writing has not yet been automated). Specifically, orthographic consistency cascaded into movement production, but it was modulated by task and grade, as this effect was only evident for 2nd grade children when they were asked to perform a spelling-to-dictation task.

Although several studies have found that the sublexical route of spelling has an effect on handwriting movements, the ability of lexical variables to modulate peripheral processes during writing is less clear. This study addresses the hypothesis that word frequency affects writing durations only during writing acquisition, and that at some point of development, the handwriting system becomes a relatively autonomous system unaffected by lexical variables. Spanish children attending Grades 2, 4, and 6 performed a spelling-to-dictation and a copy task in which word frequency was manipulated. Results revealed that written latencies decreased with age, especially between Grades 2 and 4, and that writing durations decreased between these two groups. All these measures were longer during copying but the effect of task on written latencies and in-air pen trajectories was smaller for older children. Crucially, a significant word frequency effect on writing durations was observed only in Grade 2. This effect was marginally significant in Grade 4 and disappeared in Grade 6. However, all groups showed a similar effect of word frequency on written latencies. These findings suggest that lexical processes impact peripheral processes during writing acquisition and that this influence diminishes to eventually disappear at some point in development.

Different studies have demonstrated that people with dyslexia have difficulties in acquiring fluent reading and writing. These problems are also evident when they learn a second language. The aim of our study was to investigate if there is a linguistic transfer effect for writing in children with dyslexia when they face tasks in English (L2), as well as the possible influence of other linguistic skills (spelling, vocabulary and reading) in English (L2) and in Spanish (L1). Participants completed a series of tasks both in Spanish and English: a picture naming task, a word reading task, a word spelling task, and a written composition of which we analysed its quality through different variables provided by the Coh-metrix software. Our results revealed that children with dyslexia show similar or parallel performance in written composition in both languages, which could imply a language transfer effect from L1 and L2. Besides, basic language skills are related to the characteristics of written composition to a greater extent in English than in Spanish, suggesting the impact of these on the quality of written composition.

La posibilidad de predecir el aprendizaje de la lectura y la escritura ha sido objeto de numerosas investigaciones. Las habilidades de procesamiento fonológico y velocidad de denominación aparecen entre los mejores predictores en la mayor parte de los estudios. Sin embargo, muchos de los resultados se han obtenido en lenguas diferentes del castellano y con estudios que evalúan esas capacidades cuando los niños ya saben leer, por tanto la relación de la lectura y escritura con otras habilidades podría ser fruto del aprendizaje. El objetivo de este estudio fue determinar qué variables permiten predecir la adquisición de la lectura mecánica, así como de la escritura, en castellano. Se aplicaron tareas de conciencia fonémica, repetición de pseudopalabras, amplitud de memoria, fluidez verbal y denominación rápida y automatizada, a un grupo de 50 niños prelectores. Dieciocho meses después, cuando ya sabían leer y escribir, se les evaluó en lectura y escritura. Con los datos obtenidos, se realizaron análisis de correlación de Pearson, análisis factorial y análisis de regresión lineal. La conciencia fonológica fue la variable que mejor predijo la exactitud lectora y la escritura, mientras que la denominación rápida de dibujos predijo la velocidad lectora. Estos datos indican que es posible pronosticar la adquisición de la lectura y escritura antes de su enseñanza. Así mismo, nos sugieren que es posible intervenir tempranamente, especialmente en aquellos niños que presenten riesgo de dificultades de aprendizaje.The prediction of reading and writing acquisition has been the subject of numerous research studies, given the importance of the issue. Phonological processing skills and rapid automatic naming are among the best predictors in most research studies. However, many of the results have been obtained in languages other than Spanish, and from studies that assess these skills in children who are already readers. Therefore, the relationship between reading and writing and other skills could be the result of learning these skills. The aim of this study was to identify variables that predict the acquisition of mechanical reading and writing in Spanish. A group of 50 pre-reading children participated in different tasks (phonemic awareness, pseudoword repetition, memory span, verbal fluency and Rapid Automatic Naming), and eighteen months later, when they could read and write, literacy skills were evaluated. Pearson correlations, factor analysis, and linear regression analysis were carried out on the data. Phonological awareness was the variable that best predicted reading accuracy and writing, while rapid automatized naming of pictures predicted reading speed. These data indicate that it is possible to predict the acquisition of reading and writing skills before they are taught. Furthermore, these results suggest that early intervention is possible, especially in those children who are at risk of learning difficulties. [ABSTRACT FROM AUTHOR]
