RESUMO
El presente trabajo busca contribuir a la comprensión de las dificultades en la adquisición de velocidad lectora en niños que crecen en contextos de pobreza. Se realizaron dos estudios: el primero se propuso comparar los perfiles cognitivos de niños con y sin dificultad en el desarrollo de la velocidad en el reconocimiento de palabras. Participaron 68 niños de 6to grado de zonas vulneradas del conurbano bonaerense: 22 niños presentaban adecuada precisión pero baja velocidad lectora y 46 niños conformaron el grupo de comparación, con niveles promedio de precisión y velocidad. A ambos grupos se les administraron pruebas de conciencia fonológica, denominación rápida, memoria verbal y escritura convencional. Exceptuando la prueba de memoria, en el resto de las pruebas el grupo con baja velocidad lectora presentó desempeños inferiores a los del grupo de comparación. El segundo estudio buscó explorar en qué medida una intervención pedagógica permitía mejorar la velocidad lectora. Para ello, los "lectores lentos" del Estudio 1 participaron de una situación pre-test-intervención para promover el desarrollo de la velocidad lectora vía formación de representaciones ortográficas-postest. Los resultados del Estudio 2 mostraron que la intervención con lecturas repetidas y aceleradas de palabras modificó significativamente el tiempo de lectura de las palabras de entrenamiento. Los datos también sugieren que el trabajo con unidades subléxicas en la intervención permitió transferir la velocidad ganada en las palabras de entrenamiento a palabras de transferencia, palabras no trabajadas en las sesiones, pero con unidades subléxicas incluidas en las palabras de entrenamiento.
Reading speed is achieved based on automatic word recognition and, together with prosody, constitutes an essential link between word recognition and text comprehension. Despite the relevance of reading speed acquisition for success at school, a high percentage of children growing up in poverty contexts face difficulties in achieving automatic word recognition. Consequently, this paper aims to contribute to the understanding of difficulties in reading speed acquisition in children growing in poverty contexts. Two studies were designed. In the first study, in order to explore the origin of difficulties in developing word reading speed, a comparison of the cognitive profiles of children from low-in-come backgrounds with and without difficulties in this ability was carried out. In a previous study, norms were obtained for accuracy and speed in a word reading test. Participants were 168 6th grade children from several educational institutions attending children growing up in poverty contexts in Buenos Aires, Argentina. In the present study, the same word reading test was administered to 96 6th grade children. Based on the norms obtained in the previous study, two groups of children were identified: a group who performed at or above the 50th percentile in reading accuracy but below the 30th percentile in reading speed and another groupper forming at or above the 50th percentile in both measures. The first group was made up of 22 children, and the second one, of 46 children. The remaining 28 children were not included in the study because they performed below the 50th percentile in reading accuracy. Additional tests measuring phonological awareness, rapid naming, verbal memory and word spelling were administered to children in both groups. Between-groups comparisons in these tasks showed that children with speed acquisition difficulties underperformed the other group in the tests tapping phonological awareness, rapid naming and spelling. These results suggest that the children in the group experiencing reading difficulties were still using the phonological route for word recognition. The second study aimed to explore whether a specifically designed educational intervention could enable children with low reading speed from the previous study to increase their reading speed. Both groups of children (with and without reading speed difficulties) were administered two additional reading tests: an experimental test comprising target words which would subsequently be included in the training study for the children with reading speed difficulties; and a reading test of additional words and pseudo words not targeted in the training study, but considered transfer items because they comprised sub lexical units that were included in the target words to be trained during the intervention. These same reading tests were re-administered as a post-test, after the reading intervention for the reading speed difficulties group. The training study aimed to promote reading speed via the acquisition of orthographic representations. The intervention involved two weekly individual sessions lasting 20 minutes each. Each child participated of a total of 15 sessions. Each session included repeated and accelerated reading of lexical units, as well as activities for promoting the analysis of sublexical units included in the target words and also present in the transfer pseudo words from the post-test. The comparison between the pre- and post-test performance of the training group showed a statistically significant increase in reading speed both of trained and transfer words, an increase that was not obtained for the comparison group. This result suggests that during the intervention children were able to develop orthographic representations of the trained lexical units, but also of the sub lexical units that were present in both the target and the transfer words. Educational implications from this study point to the importance of repeated and accelerated reading for increasing speed, a critical reading ability.
RESUMO
Resumen Un cambio en la forma de evaluar la lectura en México en la educación primaria ha sido la intro ducción de la medición de la velocidad de lectura (palabras por minuto) del alumno como principal indicador de logro para la comprensión lectora. Esto tiene implicaciones directas en la enseñanza de la lectura. El objetivo de este estudio es examinar la relación entre velocidad lectora y comprensión lectora en una muestra de niños mexicanos entre 1° y 4° grados, para: a) identificar la forma en que la velocidad de lectura de textos y la velocidad de lectura de palabras inventadas se relacionan con la comprensión lectora y b) si estas relaciones difieren entre el ciclo 1 (1.° y 2.° grados) y el ciclo 2 (3.° y 4.° grados) de educación primaria. Se plantearon tres hipótesis y una pregunta de investigación. Las hipótesis fueron: 1) la relación entre la velocidad lectora en textos regulares tendrá una mayor asociación que la velocidad lectora de pseudopalabras con la comprensión lectora a lo largo de los cuatro grados; 2) la velocidad lectora de pseudopalabras tendrá una asociación mayor con compren sión lectora en el ciclo 1 que en el ciclo 2 y; 3) la velocidad lectora de textos regulares tendrá una asociación mayor con comprensión lectora en el ciclo 1 que en el ciclo 2. La pregunta de investiga ción exploratoria indagó si la velocidad sigue siendo predictiva de la comprensión lectora después de considerar la precisión. Los resultados aportan evidencia que apoyan las tres hipótesis y el análisis realizado para la pregunta de investigación mostró que la velocidad de lectura de textos sólo explica ba una varianza adicional del 6% después de controlar la precisión de lectura de pseudopalabras. Los resultados son interpretados en el contexto de la literatura existente.
Abstract: A change in the way Reading is evaluated in Mexico in primary education has been the introduction of measuring reading speed in students. This has direct implications in the teaching of reading. The objective of this study was to examine the relationship between reading speed and reading compre hension in a cross-sectional sample of Mexican children between 1st and 4th grades, in order to: a) identify the way that text reading speed and pseudoword reading speed are related to reading comprehension; b) identify whether these relationships differ between 1st cycle (1st and 2nd grades) and 2nd cycle (3rd and 4th gra des). Three hypotheses and one research question were posited. The hypotheses were: 1) The relationship between text reading speed and reading comprehension will be stronger than that of word reading speed; 2) Pseudoword reading speed will have a stronger association with reading comprehension in the first cycle; 3) Text reading speed will have a stronger association with reading comprehension in the first cycle. An exploratory research question was formulated to evaluate whether speed is still predictive of reading comprehension beyond the contribution of accuracy. Results support the hypotheses while the analysis carried out for the research question showed that text reading speed added only 6% of variance after accounting for reading accuracy. Findings are interpreted in light of the existing literature.

El objetivo de esta investigación fue identificar las características de precisión, comprensión y velocidad lectora en niños con Trastorno del Aprendizaje (TA) de la lectura. Participaron 14 niños entre 8 y 11 años diagnosticados según los criterios del DSM IV-Tr a quienes se les aplicó la prueba de lectura de la Evaluación Neuropsicológica Infantil (ENI). Los resultados muestran características específicas del trastorno de acuerdo con el género, edad y nivel escolar. El desempeño fue bajo en precisión en lectura de textos y velocidad de lectura. Los errores más frecuentes fueron la sustitución literal y derivacional, error en palabra funcional y falla en el ritmo lector. Se concluye que el TA de la lectura tiene manifestaciones variadas, y los criterios de diagnóstico no contemplan procesos que pueden subyacer al mismo. Se recomienda que la evaluación haga énfasis en las tareas en que se presentan mayores dificultades y la rehabilitación responda a características particulares del trastorno.
The aim of this research study was to identify the characteristics of precision, comprehension and reading speed in children with Reading Learning Disability. Fourteen children, between the ages of 8 and 11years old, participating in the study, were diagnosed according to the DSM IV-Tr criteria. They were assessed through the reading test taken from the Evaluación Neuropsicológica Infantil (ENI) (Neuropsychological Assessment for Children). Results showed specific characteristics of the disability according to gender, age and school level. Performance was low on text reading precision and reading speed. The most frequent errors were literal and derivational substitution, error in functional word and failure in reading rhythm. The study concluded that the Reading Learning Disability has diverse manifestations and that diagnostic criteria may not include processes underlying the disability. It is recommended that assessment processes emphasize tasks where major difficulties can be found and that rehabilitation strategies respond to particular characteristics of the disability.
