Hemispheric Differences between Japanese Kanji and Kana in a Picture-Word Matching Task

Abstract:Reaction times to match words to pictures were obtained from 48 Japanese adults, to see whether Japanese Kanji (logographic) and Kana (syllabic) characters are processed preferentially in the right (RH) and left (LH) hemispheres respectively. This was so; when words and pictures were lateralized to the same hemisphere, Kanji was processed faster by the RH, and Kana by the LH, although all hemisphere effects disappeared when the picture was presented centrally. (To minimize any intrinsic LH advantage, overt phonological processing was not required. There was no intrinsic RH advantage for picture processing; pictures were processed equally well by both hemispheres.) It seems that the RH has special semantic capabilities.
