摘要:

形声字是由表示意义范畴的义符(形旁)和表示发音信息的声符(声旁)组合而成, 以往研究虽然肯定了声旁在形声字加工中的作用, 但对形旁的作用仍存在一定争议。结合行为和脑电技术, 采用汉字判断任务, 以形旁和声旁均为独体字的形声字作为实验材料, 通过操纵形旁频率和声旁频率, 本研究进一步探讨了形旁和声旁在形声字识别中的作用。行为结果(实验1)发现形旁频率并未引发反应时和错误率上的显著变化, 而声旁频率在反应时和错误率上均产生了显著的效应, 相对于低频声旁, 高频声旁条件下的反应时更长、错误率更高。脑电结果(实验2)发现, 相对于低频形旁, 高频形旁在前脑区引发了一个波幅更小的N400; 而声旁频率不仅可以在全部脑区引发N400的变化, 同时在左脑的前、中脑区引发了P200的变化。相对于低频声旁, 高频声旁所引发的P200波幅更小, N400波幅更大。两实验结果说明, 在形声字识别中, 形旁和声旁均可以产生作用, 但形旁的激活时间要晚于声旁, 且作用相对较弱。

Abstract:

The majority of Chinese characters are compound characters, and around 80% of the compound characters are phonograms which are comprised of a semantic radical and a phonetic radical. The semantic radical usually implies the meaning of the phonogram (e.g., 桐, tong2: tung, whose semantic radical is 木, mu4: wood), and the phonetic radical offers a phonological clue for the pronunciation of its host phonogram (e.g., 桐, tong2: tung, whose phonetic radical is 同, tong2: together/same). Since the semantic and phonetic radicals have different functional values, some researchers turned to investigate the issue whether their distinctive functions would generate different processing patterns during the phonogram recognition. However, regretfully, current results are confusing, with some studies reporting that the effect of the phonetic radicals were earlier and stronger than that of semantic radicals, however, others assuming that the semantic radicals played a predominant role.

Therefore, the present study was conducted to explore the effects of semantic and phonetic radicals during the phonogram recognition, especially focusing on the relative importance of them. Two kinds of radical frequencies were manipulated: semantic radical frequency and phonetic radical frequency. Different from prior research, both semantic and phonetic radicals are standalone characters in the present study in order to make sure some confusing variables such as the pronunciation and the other lexical information are kept consistent between the two types of radicals.
Behavioral results (Experiment 1) revealed only phonetic radical frequency could influence the processing of phonogram, the reaction time of phonograms containing high-frequency phonetic radicals was longer and error rate was higher than those containing low-frequency phonetic radicals. However, ERP results (Experiment 2) showed that both semantic radicals and phonetic radicals could play a role in Chinese phonogram recognition. High-frequency phonetic radicals elicited a smaller P200 during 200~300ms time window and a larger N400 around 350~500ms time window as compared to the low-frequency ones. By contrast, the high-frequency semantic radicals elicited a smaller N400 during the time window of 350~450ms than did the low-frequency ones.
The present results indicated that both semantic and phonetic radicals could be activated and play a role in Chinese phonogram recognition. But the effect of phonetic radicals was found to be earlier as it was firstly reflected by P200 effects which a component was proved to indicate the sub-lexical orthographic processing. However, both semantic and phonetic radicals could influence the semantic extraction of its host phonograms, as reflected by the N400 effects. Such results were interpreted in terms of the properties of semantic and phonetic radicals in Chinese orthographic system.
