ABSTRACT
OBJECTIVE: To verify the auditory selective attention in children with stroke. METHODS: Dichotic tests of binaural separation (non-verbal and consonant-vowel) and binaural integration - digits and Staggered Spondaic Words Test (SSW) - were applied in 13 children (7 boys), from 7 to 16 years, with unilateral stroke confirmed by neurological examination and neuroimaging. RESULTS: The attention performance showed significant differences in comparison to the control group in both kinds of tests. In the non-verbal test, identifications the ear opposite the lesion in the free recall stage was diminished and, in the following stages, a difficulty in directing attention was detected. In the consonant- vowel test, a modification in perceptual asymmetry and difficulty in focusing in the attended stages was found. In the digits and SSW tests, ipsilateral, contralateral and bilateral deficits were detected, depending on the characteristics of the lesions and demand of the task. CONCLUSION: Stroke caused auditory attention deficits when dealing with simultaneous sources of auditory information.
RESUMO
OBJETIVO: Verificar a habilidade de atenção seletiva em crianças com acidente vascular cerebral (AVC). MÉTODOS: Foram aplicados testes dicóticos de separação (não verbal e consoante-vogal) e integração - dígitos e Staggered Spondaic Words Test (SSW) - binaural em 13 crianças (7 meninos), entre 7 e 16 anos, com AVC unilateral confirmado por neuroimagem. RESULTADOS: O desempenho atencional diferiu entre os grupos na realização de ambos os tipos de tarefa. Ao teste não verbal, houve menor quantidade de identificações com a orelha contralateral à lesão em atenção livre e dificuldade de focalizar a atenção nas etapas direcionadas. No teste consoante-vogal, houve modificação da assimetria perceptual e dificuldade de focalizar a atenção nas etapas direcionadas. Nos testes de dígitos e SSW, foram constatados défices ipsilaterais, contralaterais e bilaterais dependendo das características da lesão e da demanda da tarefa. CONCLUSÃO: As crianças com AVC apresentaram défices na habilidade de atenção seletiva em presença de fontes simultâneas de informação auditiva verbal e não verbal.
