Abstract

This study aimed to investigate the applicability and performance of normal hearing adolescents with the new Dichotic Sentence Identification Test in Brazilian Portuguese in the free and directed attention stages, according to gender and ear side variables. The sample was composed of 28 subjects, 20 women and 8 men, aged between 12 and 17 years of age, with mean age of 15:8 years.
