| Research Abstract |
We compared differences in activity in both cerebral hemispheres in response to three auditory stimuli in native and nonnative speakers of Japanese in a more natural experimental setting using NIRS. The results confirmed that native Japanese speakers tend to process IS in the same cerebral hemisphere (73.3%) as they do JL and vowel sounds. Nonnative Japanese speakers tend to process IS in the opposite hemisphere (70.0%) from that which processes JL and vowel sounds. This supports the previous results obtained using Tsunoda's methods.
