ABSTRACT Objective: to analyze the influence of different combinations of verbal stimuli on the responses of the cognitive auditory evoked potential of children with speech sound disorders and to compare the P300 responses, considering the combinations of stimuli in the different severity of speech sound disorders. Methods: nineteen children in the mean age of 6.75 years old, of both sexes, diagnosed with speech sound disorder, participated in the study. All participants were submitted to the cognitive auditory evoked potential - P300 test, performed with two combinations of verbal stimuli (BA/DI and BA/GA). For statistical analysis it was used the Student T-test. Results: a statistically significant difference was observed for the latency values (p=<0.001*) and for the amplitude values (p=<0.001*) between the two combinations of stimuli. Also, statistically significant difference was observed between the combinations evaluated in the different severity of the speech sound disorder. Conclusion: the combination of stimuli /BA/ x /DI/ demonstrated lower latency and higher amplitude values in the Cognitive Evoked Potential assessment in children presented with speech sound disorder.

RESUMO Objetivo: detectar a sensibilidade, para avaliar a habilidade de resolução temporal, comparando os testes Randon Gap Detection Test (RGDT) e Gaps- In-Noise (GIN) além de sugerir valores de referência nestes testes para idosos. Métodos: participaram 38 idosos, 24 mulheres e 14 homens, com idades entre 60 e 82 anos, com audição normal ou perda auditiva neurossensorial até moderada; com simetria entre as orelhas; timpanograma tipo A, reflexos acústicos presentes, com queixa de processamento auditivo. Todos Foram submetidos a avaliação básica para caracterizar a audição periférica, RGDT e GIN. Resultados: a sensibilidade encontrada para o teste RGDT na identificação da habilidade de resolução temporal foi de 88,64% e no GIN de 67,65%. Os valores médios para o limiar de detecção de gap no teste GIN encontraram-se em torno de 8ms e para o teste RGDT em 23,13ms. Conclusão: o teste RGDT demonstrou maior sensibilidade para detecção da alteração da habilidade de resolução temporal. Os valores dos limiares de resolução temporal, sugeridos como valores de referência para idosos, são de 8ms para o GIN e 23,13 ms para o RGDT.

ABSTRACT Purpose: detecting the sensitivity to evaluate the temporal resolution ability, by comparing Randon Gap Detection Test (RGDT) and Gaps- In-Noise (GIN) tests, in addition to suggesting reference values in these tests for elderly people. Methods: 38 elderly people, 24 women and 14 men, aged between 60 and 82 years, with normal hearing or sensorineural to moderate hearing loss; with symmetry between the ears; Type A tympanogram, acoustic reflex, with auditory processing complaints. All patients underwent basic evaluations to characterize the peripheral hearing - RGDT and GIN. Results: the sensitivity found for RGDT regarding the identification of the temporal resolution ability was 88.64% and 67.65% in GIN. The mean values for the gap detection thresholds in GIN test were around 8ms and for the RGDT test in 23,13ms. Conclusion: RGDT test presented greater sensitivity for detecting the change in temporal resolution ability. The values of temporal resolution thresholds suggested as reference values for the elderly people, are 8ms for GIN and 23.13 ms for RGDT.
