ABSTRACT
UNLABELLED: Hearing has an important role in human development and social adaptation in blind people. OBJECTIVE: To evaluate the performance of temporal auditory processing in blind people; to characterize the temporal resolution ability; to characterize the temporal ordinance ability and to compare the performance of the study population in the applied tests. METHODS: Fifteen blind adults participated in this study. A cross-sectional study was undertaken; approval was obtained from the Pernambuco Catholic University Ethics Committee, no. 003/2008. RESULTS: Temporal auditory processing was excellent--the average composed threshold in the original RGDT version was 4. 98 ms; it was 50 ms for all frequencies in the expanded version. PPS and DPS results ranged from 95% to 100%. There were no quantitative differences in the comparison of tests; but oral reports suggested that the original RGDT original version was more difficult. CONCLUSIONS: The study sample performed well in temporal auditory processing; it also performed well in temporal resolution and ordinance abilities.

A audição exerce um papel importantíssimo no desenvolvimento e adaptação social dos pacientes cegos. OBJETIVOS: Avaliar o desempenho do processamento temporal de cegos; caracterizar a habilidade de resolução temporal, segundo tempo e frequência; a ordenação temporal de cegos usando o teste de padrão de frequência e comparar o desempenho da população estudada para os testes de processamento aplicados. METODOLOGIA: Participaram do estudo 12 adultos portadores de cegueira. O estudo foi do tipo transversal, aprovado pelo Comitê de Ética da Universidade Católica de Pernambuco sob nº 003/2008. Para a coleta de dados, foi utilizado o RGDT em suas duas versões e os testes de padrão de duração (TPD) e de frequência (TPF). RESULTADOS: Foi evidenciado excelente desempenho para o processamento temporal, média de 4,98 para o limiar composto na versão original do RGDT e 50 ms de reposta para todas as frequências na versão expandida. Os resultados do TPD e TPF variaram de 95 por cento a 100 por cento de acertos. Não houve diferença quantitativa quando comparados os testes avaliados, mas relatos verbais apontam o RGDT original como o mais difícil. CONCLUSÃO: A amostra avaliada apresentou bom desempenho do processamento temporal, bom desempenho para as habilidades de resolução temporal e ordenação temporal.
