| 摘 要： | 通过视觉呈现汉语双字词,在词汇决定实验中操纵启动词和目标词的语义距离,得到了一个对语义加工敏感的P240成分,它在头皮中央偏左的部位较早出现,头皮右侧的P240虽然出现较晚,但波幅较大,它可能是一种与汉语语义加工有关的新的ERP成分。

| Abstract: | The experimental materials were visually presented two-character Chinese words.The semantic distance between priming words and target words were manipulated.P240,a component sensitive(to semantic) processing was found.The P240(emerged) early on the left side of the central scalp.Later a P240 also appeared on the right side,and its amplitude was larger.This potential might be a new ERP component related to semantic processing of Chinese words. |
