Tatiana Rocha Silva Fernanda Abalen Martins Dias About the authors

PURPOSE: To evaluate the interhemispherical auditory integration ability between female and male individuals. METHODS: Participants were 30 individuals - 15 female and 15 male - aged between 18 and 25 years, without hearing complaints and with hearing within normal limits. Data collection was carried out using the non-verbal dichotic test, the dichotic digits test, and suppressive transient otoacoustic emissions. RESULTS: In the non-verbal dichotic test, in the stage of right attention, there was difference between genders regarding the number of correct responses in the right ear. In the dichotic digits test, in binaural integration, there was difference between genders regarding the percentage of correct responses in the right ear. In the stage of directed attention, there was a tendency towards difference between genders on the percentage of correct responses in the left ear. Among female subjects, there was a tendency towards difference between right and left ears in the non-verbal dichotic test, free attention stage, and there was difference between ears in selective attention. In the dichotic digits test, in binaural integration, there was a tendency towards difference between ears. CONCLUSION: Differences were observed between male and female individuals in some abilities, while in others there was similarity of responses.
