目的:探讨中文听觉双字词认知中的正字法即时激活效应。方法:采用事件相关电位(ERP)技术,操纵3种双字词条件(一致性:一致、首字不一致、尾字不一致),选择9个电极,使用时间窗分析技术,以50ms为一个时间窗分析300-350ms以及375-675ms时段的脑电波。结果:对前部脑电波平均波幅进行方差分析发现,三种实验条件在575-625ms时间窗差异显著,而在625-675ms时间窗差异边缘显著。首字不一致和一致条件在575-625ms时间窗差异显著,而在625-675ms时间窗差异边缘显著。结论:在中文听觉双字词认知中可能同样存在正字法即时激活效应。
Objective: To explore the immediate activation effect of orthography in Chinese double-word auditory perception. Methods: Three event-related potentials (ERP) were used to manipulate three kinds of double-word conditions (consistency: consistent, inconsistent initial words, inconsistent ending words), nine electrodes were selected and time window analysis technique was used. The brain waves of 300-350 ms and 375-675 ms were analyzed. Results: An analysis of variance of the average amplitude of the anterior cerebral wave showed that there were significant differences between the three experimental conditions in the time window of 575-625ms, and significant differences in the time window of 625-675ms. The first inconsistent and consistent terms have significant differences in the time window of 575-625 ms, but significant differences in the time window of 625-675 ms. Conclusion: There may be an instant activation effect of orthography in the cognition of Chinese double words.
