Abstract
We examined the graphemic processing mechanism of Kanji recognition by measuring recognition thresholds of Kanji images of different spatial frequencies, strokes and visual angles. Twenty-eight subjects participated in the experiment. The lowest thresholds were observed in the center spatial frequencies of 4.00-5.66cycles/character. The thresholds of the original images were, however, lower than them. The effects of strokes were found to be strong only in low spatial frequencies, which indicated the difference in processing between high and low frequency bands. The effects of visual angles showed that Kanji recognition was not influenced by cycles/degree, but by cycles/character.
