Relationship between phonological working memory, metacognitive skills and reading comprehension in children with learning disabilities

Abstract Reading requires the activation of several cognitive processes, some of which are basic, e.g. recognizing letters and words, whereas others are complex, such as working memory and ability to think about one's own learning strategies. One condition for fulfilling a complex cognitive task, such as understanding a text, is the ability to maintain and process information, which depends on working memory. Objective To analyze the ability of using metacognitive strategies for reading, the phonological working memory of school children with learning disabilities, and also determine if there is relation between these skills and reading comprehension. Method The sample consisted of 30 school-age children and teenagers of both genders, aged 8 to 12 years, who were enrolled in primary school. They were divided in two groups, experimental (EG) and control (CG). All children were subjected to evaluation of reading comprehension, phonological working memory, and use of metacognitive skills for reading. The results were compared between groups through the Mann-Whitney test, and correlation between variables was analyzed through Spearman correlation test. Result Statistical comparison between EG and CG showed statistically significant difference. Positive and effective correlation was observed between reading comprehension, phonological working memory and metacognitive tests. Conclusion children with learning disabilities presented deficits in phonological working memory and use of metacognitive strategies. The positive and effective correlation between the abilities analyzed suggests that failure in the phonological working memory and use of metacognitive strategies interfere with reading comprehension.

Relação entre compreensão leitora e habilidades cognitivas e linguísticas em escolares com distúrbio de aprendizagem / Relationship between reading comprehension and cognitive skills in children with learning disorder

O presente estudo verificou o perfil de desempenho de crianças com Distúrbio de Aprendizagem (DA) nas seguintes habilidades: cognitiva (memória de trabalho fonológica), metacognitiva (estratégias de leitura), linguística (vocabulário); e metalinguística (consciência sintática); comparou o desempenho nestas habilidades em crianças com DA que já estavam em processo de intervenção fonoaudiológica com aquelas não submetidas à intervenção; comparou o desempenho nas habilidades testadas de crianças com DA com aquelas sem dificuldades de aprendizagem; e verificou se há associação entre o desempenho obtido nas habilidades avaliadas com a compreensão de leitura. Sessenta crianças, de ambos os sexos, de 7 a 12 anos, foram divididas igualmente em 4 grupos: experimental 1 (GE1) composto por crianças com DA sem intervenção fonoaudiológica, experimental 2 (GE2) composto por crianças com DA em intervenção fonoaudiológica, controle 1 (GCE1) e controle 2 (GCE2), ambos compostos por crianças sem dificuldade na aprendizagem. Todas foram submetidas à avaliação fonoaudiológica por meio de procedimentos específicos. A análise dos resultados foi feita de forma descritiva, qualitativa e quantitativa. Para a análise comparativa entre os grupos foi utilizado do Teste de Mann-Whitney e para verificar o grau de correlação entre às variáveis de interesse foi aplicada a Análise de Correlação de Spearman. Adotou-se nível de significância de 5%. Os grupos experimentais evidenciaram déficits na compreensão leitora. Nas habilidades testadas a maioria das crianças dos grupos experimentais evidenciaram déficits na habilidade cognitiva e na habilidade metacognitiva, sendo adequado nas demais habilidades. Somente a habilidade cognitiva evidenciou diferença estatisticamente significante entre os grupos experimentais. As crianças...

The aim of this study was to assess the phonological working memory (PWM), the reading strategies (RS), the vocabulary (V) and syntactic awareness (SA) of children with Learning Disorder (LD). The performance of children with LD who were already under the process of speech-language intervention was compared to one’s not under intervention and both were compared to the performance of children without learning disorders. Also evaluated the relationship between the assessed skills (PWM, RS, V, SA) and reading comprehension skills. Sixty children of both genders (7 to 12 years old) were divided equally into 4 groups - experimental 1 (E1 - LD without intervention), experimental 2 (E2 - LD with intervention), Control 1 (C1) and control 2 (C2), both composed of children without difficulty in learning paired with children from the experimental groups. All children underwent specific evaluations (PWM, RS, V, SA) and 2 reading comprehension tests. A descriptive analysis of the results was performed as well as a quantitative and qualitative assessment. The results were analyzed by considering the score of each specific procedure. For a comparative analysis between groups, the Mann-Whitney test was used and to check the degree of correlation between the variables (skills and reading comprehension), the Spearman Correlation Analysis was applied. The significance level of 5% (0.050) was adopted. Both experimental groups showed deficits in reading comprehension. Most children of the experimental group showed deficits in PWM and RS. In the other skills most children showed performance classified as normal. Comparing both experimental groups, PWM was the only statistically significant test. LD children under intervention performed better than LD children without therapy, and children without LD presented significantly higher performance than both experimental groups. A positive correlation coefficient was found between the tests (PWM, RS, V, SA) and reading comprehension...

Motor, linguistic, personal and social aspects of children with Down syndrome

AbstractA global developmental delay is expected from Down syndrome, affecting motor, cognitive, linguistic and personal-social skills. However, not always these delays are proportional; different conditions occur due to several intrinsic and extrinsic variables that must be controlled to form groups of greater homogeneity.Objective To enhance personal-social, fine motor-adaptive, gross motor and linguistic skills among children with Down syndrome and compare them with typically developing children, matched for gender, socioeconomic status and mental age, while controlling some variables that interfere with the global development.Methods The ethical aspects were fulfilled (Case No. 040/2009). The following inclusion criteria were considered: participants without a history of prematurity, very low birth weight, congenital hypothyroidism, significant hearing and vision problems, and signs of Autism Spectrum Disorder. After the inclusion criteria were considered, 40 children participated in the study, of which 20 had Down syndrome (experimental group - EG), these being of both genders and with chronological ages ranging from 38 to 63 months, and the other 20 being typically developing children (control group - CG), matching the EG in terms of gender, socioeconomic status and mental age, with this age ranging from 13 to 50 months. The evaluation consisted in applying the Denver Developmental Screening Test II, a test that assesses areas such as personal-social, fine motor-adaptive, linguistic and gross motor development. The results were subjected to statistical analysis using Student’s t-test.Results A statistically significant difference was verified between the groups for the language and fine motor-adaptive areas.Conclusion Children with Down syndrome showed lower performance in language and fine motor skills when compared with typically developing children. There was no statistically significant difference in gross motor and personal-social areas. It is worth mentioning the importance of controlling the variables to deal with more homogeneous groups.

Depression and neuropsychologic testing in patients with temporomandibular disorders

A fim de determinar se existem diferenças neuropsicológicas entre os grupos, o Teste de Aprendizado Verbal da Califórnia (CVLT) e o Teste do Trigrama de Consoantes de Brown-Peterson (CCC) foram usados. A depressão foi avaliada pelo Inventário de Depressão de Beck (BDI). Os testes neuropsicológicos usados não mostraram diferenças estatisticamente significativas entre os três grupos estudados, o que pode ser devido à baixa proporção de pacientes com educação pós-secundária (25%). Entretanto, o grupo experimental (Grupos I e II) mostrou índices de depressão mais elevados (p < 0,05) que o Grupo III. Adicionalmente, o Grupo II mostrou maiores ídices de depressão (p < 0,01) que o Grupo I, e não foi encontrado diferença estatística entre os Grupos I e III. Em conjunto, estes resultados sugerem que testes de memória são altamente dependentes do nível educacional e que não podem ser utilizados em larga escala. Do mesmo modo, a depressão desempenha um papel importante não só na etiologia, como também na perpetuação da DTM
