Abstract:This study sought to determine whether hemispheric differences in language processing would lead to differences in interhemispheric transfer time (IHTT), the time it takes for information to be transmitted from one hemisphere of the brain to the other, between English speaking Americans and Japanese speakers in Japan. Compared to English, reading and writing Japanese requires more bilateral brain activity, and as a result may impact IHTT in a manner similar to previous findings regarding people that frequently play an instrument. We recruited participants from both the United States and Japan and used a manual response reaction time task to estimate the participants’ IHTT. We found that there was no cross-cultural difference in the IHTT of American and Japanese participants, which indicates the possibility that the results from other IHTT studies, which only used Americans, may be generalizable to other national groups.
