Relação entre habilidades auditivas e fonológicas em crianças com dislexia do desenvolvimento

A dislexia do desenvolvimento, dificuldade específica de leitura, é caracterizada pela dificuldade em realizar a decodificação fono-grafêmica e percepção de fonemas acusticamente semelhantes. Este estudo teve como objetivo caracterizar o desempenho de crianças com dislexia quanto às habilidades auditivas e de consciência fonológica, correlacionando-as. Participaram deste estudo crianças com dislexia e com bom desempenho escolar, submetidas a avaliações audiológica, do processamento auditivo e das habilidades fonológicas. Os resultados indicaram diferença estatisticamente significante entre as habilidades auditivas de seqüência para sons verbais, mensagem competitiva ipsi e contra-lateral, dicótico de dígitos e dissílabos alternados e ainda nos subtestes de síntese, segmentação, manipulação e transposição. Os achados deste estudo evidenciaram correlação entre provas de memória auditiva e manipulação silábica e fonêmica e associação entre habilidades auditivas e fonológicas, sugerindo que os processos auditivos interferem diretamente na percepção de aspectos acústicos, temporais e seqüenciais dos sons para formação de uma representação fonológica estável.

Psycholinguistic abilities of children with Williams syndrome

The objective of this study was to investigate the psycholinguistic abilities of children with Williams syndrome (WS) and typically developing children using the Illinois Test of Psycholinguistic Abilities (ITPA). Performance on the ITPA was analysed in a group with WS (N = 20, mean age = 8.5 years, SD = 1.62) and two typically developing groups, matched in mental (MA, N = 20, mean age = 4.92 years, SD = 1.14) and chronological age (CA, N = 19, mean age = 8.35 years, SD = 3.07). Overall, within-group analyses showed that individuals with WS displayed higher scalar scores on the visual reception and visual association subtests. When groups were compared, we observed inferior performance of the WS group on all ITPA subtests when compared with typically developing groups. Moreover, an interaction between reception and group was found, only the WS group demonstrated superior performance on the visual reception subtest when compared to the auditory reception subtest. Evidence from this study offers relevant contributions to the development of educational intervention programs for children with WS. (C) 2011 Elsevier Ltd. All rights reserved.

Contribuição de diferentes conteúdos das aulas de educação física no ensino fundamental I para o desenvolvimento das habilidades motoras fundamentais

Introduction and objective: This study investigated the contribution of physical education (PE) classes in elementary school I for the development of basic motor skills of children from two public schools in the same neighborhood of São Paulo city, and if the practice of extreme sports besides the PE classes could differently contribute to the development of those skills. Methods: Nineteen children (9.5 +/- 0.3 years) who had two weekly PE classes composed the control group (CG) and 22 children (9.6 +/- 0.5 years) who had two weekly PE classes and three extreme sports classes composed the experimental group (EG). All children were videotaped while performing locomotor and object control motor skill subtests from the Test of Gross Motor Development (TGMD-2). The videos were analyzed and raw scores were obtained according to the quality of the observed movement, and equivalent motor age was also estimated for both subtests. Results: The results indicated that the EG presented higher raw scores compared to CG in the locomotor subtest and both groups presented similar scores in the object control subtest. Moreover, EG presented higher equivalent motor age in the locomotor subtest compared to CG and neither group presented differences between equivalent motor age and chronological age in the object control subtest. Conclusion: Based on these results we conclude that PE classes in elementary school appropriately contributed to the development of basic motor skills, since neither group presented difference between equivalent motor age and chronological age, and that extreme sports classes contributed even more for the development of locomotor skills.

Distúrbios de memória em pacientes epilépticos

The author studied the mnemonic activity from epileptic patients with complex partial seizures (CPS), with the aims: 1) to identify memory disorders; and 2) to compare the patients' with the controls' results. Fifty adult patients and 20 subjects without neuropsychiatric disorders were studied. The methods consisted in: 1) investigation of the mnemonic activity through the Wechsler Memory Test (subtests: Storage and Recall, Recent Memory, and Immediate Memory); 2) comparison among the results of both groups; association from mnemonic activity with brain SPECT. In the three subtests, the patients showed cognitive performance significantly lower than the controls (p <0,05). It was found association from reduced blood flow, mainly in left temporal region, with memory impairment of the three subtetsts. The conclusion was that the CPS are associated to memory impairment.

Intelligence functions disorders in patients with complex partial epilepsy

Objective: To compare the performance of patients with complex partial epilepsy with the normal controls in the subtests of an instrument used to assess intelligence function. Method: Fifty epileptic patients, whose ages ranged from 19 to 49 years and 20 normal controls without any neuropsychiatric disorders. The Wechsler-Bellevue adult intelligence test was applied in groups, epileptic patients and control subjects. This test is composed of several subtests that assess specific cognitive functions. A statistical analysis was performed using non-parametric tests. Results: All the Wechsler-Bellevue subtests revealed that the intelligence functions of the patients were significantly inferior to that of the controls (p<0.05). This performance was supported by the patient's complaints in relation to their cognitive performance. Conclusion: Patients with complex partial epilepsy presented poorer results in the intelligence test when compared with individuals without neuropsychiatric disorders.

A escola e o desenvolvimento motor em escolares

Este estudo teve como objetivo investigar o nível de desempenho motor das habilidades motoras fundamentais e a relação do mesmo com as oportunidades de vivências motoras dentro do contexto escolar de meninos e meninas na faixa etária de seis anos e seis meses a sete anos e onze meses de duas escolas da rede pública municipal de ensino do distrito de Icoaraci/PÁ, participou deste estudo uma amostra de 39 crianças sendo 16 meninas e 23 meninos. Foi utilizado como instrumento de avaliação do desempenho motor dos participantes o TGMD2 (Teste of Gross Motor Development); para a avaliação do contexto escolar, foram realizadas filmagens de situações de recreio e aulas de Educação Física; uma entrevista estruturada também foi aplicada para investigação das oportunidades de vivências motoras fora do contexto escolar. A análise de Variância (ANOVA) e teste de continuidade (Tukey HSD Post HOC Test) foi utilizada para o tratamento das médias das idades cronológica, locomotora e manipulativa, o quociente de desenvolvimento e os escores brutos dos subtestes locomotores e manipulativos e para análises por gêneros e por escolas foi realizado o Test “t” para amostras independentes. Para a análise das verbalizações das preferências das crianças quanto o tipo de brincadeira, local, parceiros e ofertas de atividades recreativas, esportivas e culturais também foi realizada a ANOVA. Os resultados sugerem que 51,8% da amostra apresentaram nível de desenvolvimento motor na média, 2,6% acima da média, 28,2% abaixo da média, 12,8% pobre e 5,1% muito pobre. A análise das habilidades motoras demonstrou um comportamento bastante heterogêneo nos resultados encontrados evidencia pelo elevado desvio padrão principalmente no salto com um pé, corrida lateral e galope (locomotoras) e chutar e rebater (manipulativas), quando todos os participantes foram levados em conta, encontrou-se diferenças significativas somente nas habilidades de correr e corrida lateral (locomotoras) e no rebater e chutar (manipulativas), quando se levou em conta o sexo verificou-se diferenças estatisticamente significativa somente na idade manipulativa, onde os resultados das meninas foram melhores que os dos meninos. Quanto às oportunidades de vivências motoras fora do contexto escolar a brincadeira preferida entre os participantes nas duas escolas é o brincar de bola, o local de preferência para as brincadeiras, o quintal e como parceiros prediletos são os amigos e irmãos ao mesmo tempo. A análise do recreio apontou que as brincadeiras mais freqüentes em ambas as escolas são o brincar de correr, brincar de pira, trocar figurinhas e conversar, quando o gênero é levado em conta, não foram encontradas diferenças os meninos e as meninas em ambas as escolas brincam das mesmas coisas, com relação a participação em atividades recreativas, esportivas e culturais, os resultados apontaram para que 100% da amostra não realiza estas atividades fora do contexto escolar. A análise das aulas de Educação Física apontou para diferenças na estrutura e na oferta do material entre as escolas, sendo a as condições da escola “B” muito superiores a da “A”, porém no que diz respeito à metodologia utilizada pelas professoras, elas são similares. Os resultados demonstram que as oportunidades de vivências motoras dentam do contexto escolar são primordiais para o desenvolvimento motor dos escolares, pois em muitos casos é a única oportunidade que tem para estimular o desenvolvimento motor dos escolares.

Brazilian adaptation of the Woodcock-Johnson III cognitive tests

An adaptation of the standard battery of Woodcock-Johnson III Tests of Cognitive Abilities (WJ-III) for Brazilian children and youth was investigated. The sample was composed of 1094 students (54 percent girls), ages 7-17, living in Sao Paulo state (91 percent). Items from Brazilian school books as well as from the WJ-III Spanish version (Bateria-R) were added to comprehension-knowledge tests. Brazilian words were adapted to the auditory tests according to syllabic division and stressed syllables. Items were examined through IRT and age differences through analysis of variance. Results indicated the need to remove items from all WJ-III subtests with the exception of the visual learning test. Analysis of Variance indicated significant age differences (p <= 0.001) for all tests. Thus, the importance of a Brazilian adaptation for the WJ-III was confirmed.

Auditory middle latency response and phonological awareness in students with learning disabilities

Introduction Behavioral tests of auditory processing have been applied in schools and highlight the association between phonological awareness abilities and auditory processing, confirming that low performance on phonological awareness tests may be due to low performance on auditory processing tests. Objective To characterize the auditory middle latency response and the phonological awareness tests and to investigate correlations between responses in a group of children with learning disorders. Methods The study included 25 students with learning disabilities. Phonological awareness and auditory middle latency response were tested with electrodes placed on the left and right hemispheres. The correlation between the measurements was performed using the Spearman rank correlation coefficient. Results There is some correlation between the tests, especially between the Pa component and syllabic awareness, where moderate negative correlation is observed. Conclusion In this study, when phonological awareness subtests were performed, specifically phonemic awareness, the students showed a low score for the age group, although for the objective examination, prolonged Pa latency in the contralateral via was observed. Negative weak to moderate correlation for Pa wave latency was observed, as was positive weak correlation for Na-Pa amplitude.

Cognição Numérica de crianças pré-escolares brasileiras pela ZAREKI-K

The Numerical Cognition is infl uenced by biological, cognitive, educational and cultural factors. It consists of a primary system, called Number Sense that would be innate and universal, also of secondary systems: the Calculation, implied to perform mathematical operations by means of symbols or words and Number Processing, which is divided into two components, Number Comprehension, related with the understanding of numerical symbols and Number Production, which includes reading, writing and coun-ting numbers. However, studies that show the development of these functions in children of preschool age are scarce. Therefore, aims of this study were to investigate numerical cognition in preschool Brazilian children to demonstrate the construct validity of the ZAREKI-K (A Neuropsychological Battery for the Assessment of Treatment of Numbers and Calculation for preschool children). The participants were 42 children of both genders, who attended public elementary schools; the children were evaluated by this battery and WISC-III. The results indicated signifi cant differences associated with age which children of 6 years had better scores on subtests related to Number Production, Calculation and Number Comprehension, as well moderate and high correlations between some subtests of both instruments, demonstrating the construct validity of the battery. In conclusion, preliminary normative data were obtained for ZAREKI-K. The analyses suggested that it is a promising tool for the assessment of numerical cognition in preschool children.Keywords: Mathematics, number, preschoolers, working memory, Developmental Dyscalculia.

Juvenile myoclonic epilepsy: The impact of clinical variables and psychiatric disorders on executive profile assessed with a comprehensive neuropsychological battery

Executive dysfunction is reported in juvenile myoclonic epilepsy (JME). However, batteries employed in previous studies included no more than three tests of executive function. In this study, we aimed to assess executive and attentional functions in JME using a comprehensive battery of eight tests (encompassing fifteen subtests). We also evaluated neuropsychological profiles using a clinical criterion of severity and correlated these findings with epilepsy clinical variables and the presence of psychiatric disorders. We prospectively evaluated 42 patients with JME and a matched control group with Digit Span tests (forward and backward), Stroop Color-Word Test, Trail Making Test, Wisconsin Card-Sorting Test, Matching Familiar Figures Test and Word Fluency Test. We estimated IQ with the Matrix Reasoning and Vocabulary subtests of the Wechsler Abbreviated Intelligence Scale. The patients with JME showed specific deficits in working memory, inhibitory control, concept formation, goal maintenance, mental flexibility, and verbal fluency. We observed attentional deficits in processes such as alertness and attention span and those requiring sustained and divided attention. We found that 83.33% of the patients had moderate or severe executive dysfunction. In addition, attentional and executive impairment was correlated with higher frequency of seizures and the presence of psychiatric disorders. Furthermore, executive dysfunction correlated with a longer duration of epilepsy. Our findings indicate the need for comprehensive neuropsychological batteries in patients with JME, in order to provide a more extensive evaluation of attentional and executive functions and to show that some relevant deficits have been overlooked.
