Abstract
|
|
|
For the investigation of brain asymmetry of Koreans in visual recognition of Hangul and Chinese Words, 29 normal subjects who were physically healthy and right-handed were tested using the visual half-field task performance with tachistoscopic
method
Stimuli were 12 one-letter Hangul words, 12 two-letter Hangul words, 12 one-letter Chinese words, 12 twoletter Chinese words. The stimuli were presented to computer monitor in block randomization order, Subjects were instructed to read the words
as
soon
as possible. The correct response rate and reaction time were measured and analyzed.
1) The correct response rates of one-letter and two-letter Hangul words were significantly higher in left hemisphere.
2) there was no statistically significant difference between the reaction time in left and right hemisphere to one-letter and two-letter Hangul words.
3) There was no statistically significant difference between the correct response rate in left and right hemisphere to statistically significant difference between the correct response rate in left and right hemisphere to one-letter and
two-letter
Chinese words.
4) There was no statistically significant difference between the reaction time in left and right hemisphere to one-letter and two-letter Chinese words.
These results suggest that left hemisphere was superior to right hemisphere in the recognition of Hangul, but it was not so superior in the recognition of Chinese words. In comparison with the similar studies with Chinese and Japanese, the
pattern
of
brain asymmetry in the recognition of words may be different depending on the culture and ethnic group.
