An electrophysiological investigation of the role of orthography in accessing meaning of Chinese single-character words.
This study reported the role of orthography in semantic activation processes of Chinese single-character words. Eighteen native Chinese speaking adults were recruited to take part in a Stroop experiment consisting of one-character color words and pseudowords which were orthographically similar to these color words. Classic behavioral Stroop effects, namely longer reaction times for incongruent conditions than for congruent conditions, were demonstrated for color words and pseudowords. A clear N450 was also observed in the two incongruent conditions. The participants were also asked to perform a visual judgment task immediately following the Stroop experiment. Results from the visual judgment task showed that participants could distinguish color words and pseudowords well (with a mean accuracy rate over 90 percent). Taken together, these findings support the direct orthography-semantic route in Chinese one-character words.
