Desempeño lector en niños con diagnóstico de TDAH (Trastorno de Déficit de Atención con Hiperactividad) / Reading performance in children with ADHD (Attention-Deficit/Hyperactivity Disorder)

Resumen Con el objetivo de determinar la relación entre la edad, el subtipo clínico, el carácter de la insti tución y las variables neuropsicológicas en pruebas de lectura en niños diagnosticados con Tras torno por Déficit de Atención Hiperactividad-TDAH (n= 36, inatento; n= 52) y un grupo control (n=88), se estudiaron 176 niños provenientes de escuelas públicas y privadas de la ciudad de Manizales-Caldas, con edades entre los 6 y 13 años. A estos niños se les evaluó desempeño lec tor, atención, habilidades construccionales, memoria, lenguaje y funciones ejecutivas, por medio de la Evaluación Neuropsicológica Infantil (ENI). Los resultados en el análisis por subgrupos (combinado, inatento y control) evidencian diferencias significativas. El grupo control puntuó en general más alto que ambos subtipos de TDAH. En cuanto al tipo de institución, los niños que asisten a escuelas de carácter privado, arrojaron valores superiores en comparación a los niños que asisten a instituciones educativas de carácter oficial, pero esta diferencia disminuyó a medida que avanzó la escolaridad. En relación a las variables neuropsicológicas, se halló que las variables atencionales pueden predecir la velocidad de lectura. Se concluyó que las variables escolares, la edad y el subgrupo permiten diferenciar el desempeño lector. Los resultados se discutieron y compararon con nuevos trabajos sobre la misma línea.

Abstract The aim of the present study is to determine the relation between age, clinical subtype, institu tion type and neuropsychological variables in reading tests in children diagnosed with ADHD (n= 36, inattentive; n= 52) and a control group (n=88); 176 children from public and private schools and between the ages of 6 and 13 years old from Manizales-Caldas were part of the study. Their reading performance, attention, constructional skills, memory, language and executive functions were assessed with the Evaluation Neuropsychological Infantile (ENI). The results of the analysis per subtypes (mixed, inattentive and control) show that there are significant differences. The chil dren attending private schools showed a higher performance compared to the ones from public schools; but this difference decreased as the level of schooling increased. Regarding the neuro psychological variables, the results indicated that the attention variables can predict the reading speed. It was concluded that the school variables, age and clinical subtype help to differentiate the reading performance. The results were discussed and compared with other researches of the same field.

Literacia Pré-Escolar e Desempenho na Leitura na Instrução Primária / Preschool Literacy and Reading Performance in Primary School

RESUMO A literacia pré-escolar tem recebido uma crescente atenção. Neste estudo, participaram 70 crianças que iniciaram o 1.º ano de escolaridade no ano letivo 2009/10 e que, na educação pré-escolar, frequentaram três instituições com abordagens diferenciadas de leitura e de escrita. O estudo inclui quatro medidas repetidas no tempo nas áreas da fonologia, reconhecimento de letras, palavras e velocidade de leitura. Os resultados sugerem que a abordagem específica à leitura na educação pré-escolar condiciona o desempenho da leitura na instrução primária. Contudo, essa influência parece ser atenuada com o tempo. Por outro lado, verificou-se que sujeitos que receberam instrução direta de leitura em idade pré-escolar (mas não treino fonológico) obtêm resultados significativamente superiores em tarefas fonológicas aos de sujeitos que receberam treino fonológico prolongado (mas não de leitura).

ABSTRACT The debate regarding kindergarten literacy has received increasing attention and social visibility. In this study, participants are 70 children who attended first grade in 2009/2010. Participants attended three kindergartens with unique approaches to reading. A four wave repeated measure design was conducted to investigate the growth of the children in phonological awareness, letter recognition, word recognition, and reading speed. Results suggest that the approach towards reading and writing in kindergarten affects children's performance in grades 1 and 2 of elementary school. This influence, however, seems to fade over time. Moreover, results show that children who received formal reading instruction in kindergarten, perform significantly better in phonological tasks than children who received direct and extended phonological instruction.

O papel da amplitude visuoatencional e da consciência fonêmica na aprendizagem da leitura / The role of visual attention span and phonemic awareness in learning to read

Este estudo objetivou verificar as relações entre amplitude visuoatencional (AVA), consciência fonêmica (CF) e desempenho em leitura em uma amostra de 48 alunos de 1º, 3º e 5º anos do ensino fundamental de uma escola pública de São Paulo. As crianças foram avaliadas em três sessões em tarefas de leitura de palavras isoladas, AVA, CF, inteligência não verbal, memória fonológica e limiar de identificação de letras. Os resultados indicam que a AVA e a CF se relacionam com a leitura desde o 1º até o 5º ano e que essas relações são mais fortes no 1º ano, mas continuam tendo um papel relevante no 3º ano e no 5º ano, principalmente na leitura de pseudopalavras e palavras irregulares.

This study aimed to verify the relationship between visual attention span (VAS), phonemic awareness (PA) and reading performance in a sample of 48 students from the 1st, 3rd and 5th grade from a public elementary school in Sao Paulo. Children were assessed in three sessions through a battery of tasks, which included single word reading, VAS, PA, nonverbal intelligence, phonological memory and letter identification threshold. Results showed that the VAS and PA correlated with performance in reading from 1st to 5th grade, and they play a more important role at 1st grade, but remain relevant in 3rd and 5th grade, especially in the reading of nonwords and irregular words.

Complejidad textual, lecturabilidad y rendimiento lector en una prueba de comprensión en escolares adolescentes / Textual Complexity, Readability and Reading Performance on a Comprehension Test in Adolescents School

En este artículo se estudia el problema de la lecturabilidad -la dificultad intrínseca de los textos para ser comprendidos- desde una perspectiva psicolingüística. El objetivo de este estudio fue establecer en qué medida la lecturabilidad de un texto depende no solo de sus propiedades estructurales (complejidad lingüística), sino también de las habilidades del lector y de la naturaleza de las tareas de comprensión. Se realizó una investigación de tipo cuasiexperimental en la que se construyeron dos pruebas de comprensión de lectura, manipulando la complejidad de los textos. Las pruebas incluyeron ítems para medir diversos aspectos de la comprensión según un modelo de evaluación basado en un enfoque teórico psicolingüístico. Las pruebas fueron aplicadas a 208 escolares de tres tipos de establecimientos educativos distintos. Los resultados de los análisis estadísticos de los datos permiten confirmar la hipótesis de que la lecturabilidad de los textos no depende solo de las propiedades textuales, sino de la relación de estas con las características de los lectores y las tareas de comprensión definidas en las pruebas.

In this paper, the problem of readability is studied from a psycholinguistic perspective. Readability is the intrinsic difficulty of texts to be understood. The aim of this study was to determine to what extent the readability of a text depends not only on its structural properties (linguistic complexity), but also the skills of the reader and the nature of comprehension tasks. An experimental research was carried out, in which two reading comprehension tests were developed by manipulating the complexity of texts. The tests included items to measure various aspects of comprehension according to an evaluation model based on a theoretical psycholinguistic approach. The tests were applied to 208 participants in three different types of schools. The results confirmed the hypothesis that the readability of texts depends not only on the textual properties, but also on the relationship of these with the readers' characteristics and the comprehension tasks defined in the tests.

Impact of low vision care on reading performance in children with multiple disabilities and visual impairment.

Background: Lack of evidence in literature to show low vision care enhances the reading performance in children with Multiple Disabilities and Visual Impairment (MDVI). Aim: To evaluate the effectiveness of Low Vision Care intervention on the reading performance of children with MDVI. Materials and Methods: Three subjects who were diagnosed to have cerebral palsy and visual impairment, studying in a special school were recruited for the study. All of them underwent detailed eye examination and low vision care evaluation at a tertiary eye care hospital. A single subject multiple baseline (study) design was adopted and the study period was 16 weeks. The reading performance (reading speed, reading accuracy, reading fluency) was evaluated during the baseline phase and the intervention phase. The median of all the reading parameters for each week was noted. The trend of the reading performance was graphically represented in both the phases. Results: Reading speed increased by 37 Word per minute, 37 Letters per minute and 5 letters per minute for the subject 1, 2 and 3 respectively after the intervention. Reading accuracy was 84%, 91% and 86.4% at the end of the baseline period and 98.7%, 98.4% and 99% at the end of 16 weeks for subject 1, 2 and 3 respectively. Average reading fluency score was 8.3, 7.1 and 5.5 in the baseline period and 10.2, 10.2 and 8.7 in the intervention period. Conclusion: This study shows evidence of noticeable improvement in reading performance of children with MDVI using a novel study design.

Variáveis psicossociais e desempenho em leitura de crianças de baixo nível socioeconômico / Psychosocial Variables and Reading Performance of Children with Low Socioeconomic Status

Este estudo longitudinal investigou a contribuição de fatores psicossociais para o desempenho em leitura de crianças. Participaram 59 mães e seus filhos aos 4 meses, 2, 5-6 e 9-11 anos. Correlacionou-se o desempenho em leitura das crianças a variáveis psicossociais. Encontrou-se correlações negativas entre morbidade psiquiátrica materna na primeira infância e leitura de palavras irregulares e entre o número de familiares que residiam com a criança aos 2 e 5-6 anos e o desempenho na leitura de palavras. A renda familiar aos 2 anos correlacionou-se positivamente com compreensão textual. Entretanto, apenas o número de familiares que residiam com a criança foi preditor do desempenho em leitura de palavras. Conclui-se que o desempenho em leitura relaciona-se a fatores psicossociais.

This longitudinal study investigated the impact of psychosocial factors on reading performance of children with low socioeconomic status. Fifty nine mothers and their children at 4 months, 2, 5-6 and 9-11 years of age participated. The children's reading performance was correlated with psychosocial variables. Negative correlations were found between maternal psychiatric morbidity in early childhood and reading of irregular words, and between the number of family members living with the child at 2 and 5-6 years and word reading performance. Family income at 2 years correlated positively with reading comprehension. However, only the number of family members who lived with the child was a predictor of reading performance. The results indicate that reading performance is related to psychosocial factors.
