| Outline of Final Research Achievements |
Through the present research the next three findings were mainly obtained. (1) Selective attention modulated the auditory brainstem response (ABR) during procedures of intermodal (auditory vs. visual) attention and dichotic listening. However, the ABR modulation was restricted to some stimulus parameters, which was contrasted with the generality of attention-related modulation found for late event-related potentials (negative difference waves) during dichotic listening tasks. (2) Intense exposure of contralateral noise was unnecessary for modulating the ABR during selective attention although the contralateral noise exposure had been considered as a necessary condition at the start of this research. (3) The intermodal attention modulated binaural interaction of the ABR. Binaural interaction in the ABR stands for the discrepancy between the binaural waveform and the sum of monaural ones.
