ABSTRACT

PURPOSE: To investigate the existence of correlations between the performance of children in auditory temporal tests (Frequency Pattern and Gaps in Noise - GIN) and IQ, attention, memory and age measurements. METHOD: Fifteen typically developing individuals between the ages of 7 to 12 years and normal hearing participated in the study. Auditory temporal processing tests (GIN and Frequency Pattern), as well as a Memory test (Digit Span), Attention tests (auditory and visual modality) and intelligence tests (RAVEN test of Progressive Matrices) were applied. RESULTS: Significant and positive correlation between the Frequency Pattern test and age variable were found, which was considered good (p<0.01, 75.6%). There were no significant correlations between the GIN test and the variables tested. CONCLUSIONS: Auditory temporal skills seem to be influenced by different factors: while the performance in temporal ordering skill seems to be influenced by maturational processes, the performance in temporal resolution was not influenced by any of the aspects investigated. .


OBJETIVO: Investigar a existência de correlações entre o desempenho de crianças com desenvolvimento típico em testes temporais auditivos (Padrão de Frequência e Gaps in Noise - GIN) e medidas de memória, atenção, quociente intelectual e a idade. MÉTODO: Quinze participantes, com idades entre 7 e 12 anos, sem queixas envolvendo audição e desenvolvimento cognitivo, foram submetidos aos testes de processamento temporal auditivo (GIN e Padrão de Frequência), teste de Memória (Span de Dígitos), Atenção (auditiva e visual) e testes de inteligência (Matrizes Progressivas de Raven). RESULTADOS: Foram encontradas correlações significantes e positivas entre o teste Padrão de Frequência e a variável idade, sendo essa considerada boa (p<0,01, 75,6%). Não foram verificadas correlações significantes entre o teste GIN e as variáveis testadas. CONCLUSÃO: As habilidades temporais consideradas parecem ser influenciadas por diferentes fatores: enquanto a habilidade de ordenação temporal parece ser influenciada por processos maturacionais, o desempenho para a habilidade de resolução temporal não foi influenciado por nenhum dos aspectos investigados. .

ABSTRACT

The neuropsychological tests of spatial span are designed to measure attention and working memory. The version of the spatial span test in the Cambridge Neuropsychological Test Automated Battery (CANTAB) evaluates these functions through the recall of sequences of spatial locations presented to the subject. Objective: The present study investigated how age, gender and educational level might affect the performance of the non-verbal system. Methods: A total of 60 children and adolescents aged 6 to 18 years were assessed (25 males and 35 females). Results: The results showed no gender differences in test performance. Children with six or more years of education showed better performance than children with less than three years of education. Older children had more schooling and thus were able to recall a greater number of items. Span length values proved similar to a previous large normative study which also employed the CANTAB Spatial Span (De Luca et al., 2003). Conclusion: The similarity in performance of the Brazilian children and adolescents studied and the group of Australian participants examined by the cited authors, despite the socio-cultural and economical differences, points to the suitability of the task for the assessment of attention and working memory in Brazilian children.


Testes neuropsicológicos de span visuoespacial são construídos para avaliar amplitude atencional e memória de trabalho. Na versão do teste de span visuoespacial da Cambridge Neuropsychological Test Automated Battery (CANTAB) essa avaliação é feita através de sequências de localização espacial. Objetivo: O presente estudo investiga como a idade, o sexo e a escolaridade podem afetar o desempenho nesse sistema não-verbal. Métodos: Foram avaliadas 60 crianças e adolescentes com idades entre 6 e 18 anos (25 meninos; 35 meninas). Resultados: Os resultados não mostraram diferenças no desempenho do teste entre os sexos. O grupo de crianças com seis ou mais anos de escolaridade foi melhor do que a de crianças menores de três anos de estudo. Nossos resultados sugerem que as crianças mais velhas e, portanto, com maior tempo de escolaridade conseguem se lembrar de um número maior de itens. Os valores de amplitude foram similares aos obtidos em um experimento normativo prévio amplo no qual foi utilizado o teste Spatial Span do CANTAB (De Luca et al., 2003). Conclusão: Estas concordâncias de desempenhos entre crianças e adolescentes brasileiros e o grupo de participantes australianos examinados pelos autores citados nos mostram que apesar das diferenças sócio-culturais e econômicas existentes, a tarefa é adequada para avaliação de atenção e memória de trabalho em crianças brasileiras.

ABSTRACT

Computerized neuropsychological tests can be effective and have many benefits. This paper addresses these issues using the computer-based Cambridge Neuropsychological Test Automated Battery (CANTAB) to assess Brazilian children and adults. Preliminary normative data for Brazilian children obtained in a series of CANTAB subtests are presented together with data from adults (controls) and samples of patients with multiple sclerosis and Duchenne muscular dystrophy. The results obtained in children confirmed the normative values reported for American children (Luciana & Nelson, 2002), indicating high applicability of the CANTAB battery for children in the evaluation of visual memory, working memory, planning, and set shifting. For multiple sclerosis patients, CANTAB revealed differences between the control and multiple sclerosis groups for all subtests employed, including visual memory, working memory, spatial memory, decision making, inhibitory control, and sustained attention. In children with Duchenne muscular dystrophy, the CANTAB tests revealed specific detriments in attention and memory. These results of the application of CANTAB in different patient groups indicate that the battery is appropriate for assessing several central nervous system diseases.
