Computer speech-based remediation for reading disabilities: the size of spelling-to-sound unit in a transparent orthography.

This study was designed to assess the effects of four reading-training procedures for children with reading disabilities (RD) in a transparent orthography, with the aim of examining the effects of different spelling-to-sound units in computer speech-based reading. We selected a sample of 83 Spanish children aged between 7 years 1 month and 10 years 6 months (M = 105.2, SD = 7.8) whose pseudoword reading performance was below the 25th percentile and IQ > 90. The participants were randomly assigned to five groups: (a) the whole-word training group (WW) (n = 17), (b) the syllable training group (S)(n = 16), (c) the onset-rime training group (OR) (n = 17), (d) the phoneme training group (P) (n = 15), and (e) the untrained control group (n = 18). Children were pre- and post-tested in word recognition, reading comprehension, phonological awareness, and orthographic and phonological tasks. The results indicate that experimental groups who participated in the phoneme and syllable conditions improved their word recognition in comparison with the control group. In addition, dyslexics who participated in the phoneme, syllable, and onset-rime conditions made a greater number of requests during computer-based word reading under conditions that required extensive phonological computation (low frequency words and long words). Reading time, however, was greater for long words in the phoneme group during computer-based reading. These results suggest the importance of training phonological processes in improving word decoding in children with dyslexia who learn in a consistent orthography.

Esta investigación fue diseñada para evaluar los efectos de la instrucción asistida a través de ordenador en los procesos fonológicos y de lectura en niños con dificultades de aprendizaje en la lectura (DAL) en una ortografía transparente. Para ello se manipularon diferentes tipos de unidades lingüísticas con objeto de analizar con cuál de ellas se consiguen mejores resultados.Se seleccionó una muestra de 83 niños españoles de edades comprendidas entre los 7 años y 1 mes y 10 años y 6 meses(edad M = 105.2; DT = 7.8) que presentaban una puntuación en lectura de pseudopalabras por debajo del percentil 25 y un cociente intelectual mayor que 90. Los sujetos fueron distribuidos al azar en cinco grupos diferentes: (a) instrucción basada en reconocimiento de palabras (WW) (n = 17), (b) instrucción basada en reconocimiento de sílabas (S) (n = 16), (c) instrucción basada en reconocimiento de principio-rima (OR) (n = 17), (d) instrucción basada en reconocimiento de fonemas (P) (n =15),y (e) ningún tipo de instrucción (n = 18). Se administraron distintas tareas, antes y después de finalizado el periodo de instrucción, para evaluar los efectos de la instrucción sobre la descodificación, comprensión lectora, conciencia fonológica, y procesamiento ortográfico. Los niños con DAL que participaron en la instrucción basada en el reconocimiento de fonemas y en la instrucción basada en reconocimiento de sílabas mejoraron la descodificación en comparación al grupo control. Además, los niños con DAL que participaron en las condiciones de fonema, sílaba y principio-rima solicitaron un mayor número de ayudas durante el periodo de instrucción en aquellas condiciones donde la demanda de procesamiento fonológico era mayor (v. gr., palabras de baja frecuencia y palabras largas). Sin embargo, se registraron tiempos de lectura mayores, durante el periodo de instrucción, para las palabras largas en la condición de entrenamiento basada en fonemas. Estos hallazgos sugieren que el entrenamiento en procesos fonológicos mejora la descodificación de las palabras en niños con DAL en una ortografía transparente (AU)

Locus and nature of perceptual phonological deficit in Spanish children with reading disabilities.

The aims of this study were (a) to determine whether Spanish children with reading disabilities (RD) show a speech perception deficit and (b) to explore the locus and nature of this perceptive deficit. A group of 29 children with RD, 41 chronological age-matched controls, and 27 reading ability-matched younger controls were tested on tasks of speech perception. The effect of linguistic unit (word vs. syllable) and type of phonetic contrast (voicing, place and manner of articulation) were analyzed in terms of the number of errors and the response time. The results revealed a speech perception deficit in Spanish children with RD that was independent of the type of phonetic contrast and of linguistic unit.

Evaluación de la velocidad de nombrar en las dificultades de aprendizaje de la lectura / Naming speed assessment in reading disabilities

En este trabajo se examina la velocidad de nombrar de un grupo de alumnos con dificultades de aprendizaje en la lectura (DAL) que presentan déficit fonológico, utilizando un diseño de nivel lector. Se seleccionó una muestra de 97 sujetos (52 niños y 45 niñas). Se utilizó un diseño de nivel de lectura de tres grupos: un grupo experimental formado por 29 sujetos con DAL de 4° nivel de Primaria; un grupo control de 41 buenos lectores igualados en edad con el grupo anterior; y un grupo control de 27 sujetos de 2° nivel igualados en nivel lector con el grupo con DAL. Se utilizó la técnica de Denckla y Rudel (1976), denominada Rapid Automatized Naming (RAN), para evaluar la velocidad de nombrar. Los resultados mostraron que los niños con DAL y déficit fonológicos son más lentos que los buenos lectores de la misma edad y que su velocidad de nombrar es similar a la de los buenos lectores más jóvenes. Este hallazgo sugiere que los niños con DAL y déficit fonológico no presentan un déficit en la velocidad de nombrar (AU)

The present study was designed to examine if the reading disabled (RD) children with phonological deficit show deficits in naming speed using a reading-level match (RLM) design. A sample of 97 children (52 male, 45 female) was classified into three groups: an experimental group of 29 RD children of 4th grade; a control group of 41 normal readers matched in age with the RD, and a control group of 27 younger children of 2nd grade matched in reading level with the RD group. Children were tested in naming speed using the Denckla and Rudel (1976) technique named Rapid Automatized Naming (RAN). Results showed that the RD children were slower than their age matched controls, but similar to their reading level matched controls. This finding suggests that RD children with phonological deficit did not show deficit in naming speed (AU)

Do the effects of computer-assisted practice differ for children with reading disabilities with and without IQ-achievement discrepancy?

This study was designed to assess whether the effects of computer-assisted practice on visual word recognition differed for children with reading disabilities (RD) with or without aptitude-achievement discrepancy. A sample of 73 Spanish children with low reading performance was selected using the discrepancy method, based on a standard score comparison (i.e., the difference between IQ and achievement standard scores). The sample was classified into three groups: (1) a group of 14 children with dyslexia (age M = 103.85 months; SD = 8.45) who received computer-based reading practice; (2) a group of 31 "garden-variety" (GV) poor readers (age M = 107.06 months; SD = 6.75) who received the same type of instruction; and (3) a group of 28 children with low reading performance (age M = 103.33 months; SD = 9.04) who did not receive computer-assisted practice. Children were pre- and posttested in word recognition, reading comprehension, phonological awareness, and visual and phonological tasks. The results indicated that both computer-assisted intervention groups showed improved word recognition compared to the control group. Nevertheless, children with dyslexia had more difficulties than GV poor readers during computer-based word reading under conditions that required extensive phonological computation, because their performance was more affected by low-frequency words and long words. In conclusion, we did not find empirical evidence in favor of the IQ-achievement discrepancy definition of reading disability, because IQ did not differentially predict treatment outcomes.
