汉字识别侧抑制效应的实验研究

以汉字作为实验材料,采用侧抑制任务范式,考察了不同性质冲突任务下的汉字识别情况.结果发现:反应冲突条件下的反应时显著长于无冲突条件,侧抑制效应非常明显;刺激冲突任务中,只有字音干扰条件表现出了侧抑制效应,字形和字义干扰条件下的反应时与无冲突条件均无显著差异.实验结果说明,侧抑制效应可能受认知加工阶段的影响;汉字字音与形、义特征的加工过程可能并不相同,语音的激活可能要早于语义和字形的激活.

The Flanker Effect in Chinese Character Identification

In this experiment Chinese characters were used as the material of the Flanker task, to investigate the difference in different conflict situations. The results showed that the reaction time in the conflicting condition was longer than in the no-conflict condition, so the Flanker effect was very obvious. Of stimulus conflict, only under phonetic condition did the Flanker effect showed up, and under orthographic and semantic conditions no difference was found compared with the no-conflict condition. The results indicated that the Flanker effect may be influenced by the cognitive stage. Phonetic activation might come earlier than orthographic and semantic activation.
