我们进行了先导性的脑电图实验，以检查大脑活动是否会反映日本英语学习者的英语单词的难度水平。在实验过程中，“容易”和“困难”的英语单词被视觉呈现，并回答他是否理解所呈现的英语单词的含义。我们发现，最具特征的大脑活动是在刺激呈现后400-800 ms在10-20 Hz频段的功率下降，这似乎反映了单词难度的差异。未来的研究将集中在应用机器学习技术，以便对每个单词的大脑活动进行分类。
We performed pilot electroencephalography experiments to examine whether brain activity would reflect the difficulty levels of English words for Japanese English learner. During experiment, "easy" and "difficult" English words were visually presented and the participant responded whether he understood the meaning of the presented English word. We found that the most characteristic brain activity was a power decrease in the 10-20 Hz frequency band at 400-800 ms after stimulus presentation, which seemed to reflect the differences in the difficulty of the words. Future studies will focus on applying machine-learning techniques so as to classify brain activities for each word.
