Abstract: The functional characteristic of the hemisperes for recognition of Ch- inese characters, English words and Arabic numerals tachistos-copically presented unilaterally to the left and right visual fields of 70 normal rig- ht-handed subjects was investigated. The subjects were divided into 3 gr- oups: In group 1 were 30 Chinese university students of English special field aged 18-25 years, whose native language was ideograms (Chinese ch- aracters); In group 2 were 30 foreign students, in China aged 18-25 yea- rs, who took phonograms as native language and at the same time maste- red Chinese; In group 3 were 10 foreign teachers aged 20-40 years, who didn't know Chinese. The stimulus were presented 50 msec. The results showed: Nonsignificant difference between left and right visual fields for recognition of Chinese characters and English words pre- sented to group 1 and group 2; However, a significant right field (left hemispere) superiority for English words was found in group 3; There was no difference between left and right visual fields for Arabic numerals in group 1 and group 3 (foreign students did not do the experiment) The result s mentioned above was discussed.
