Abstract

This paper describes logistic regression analyses and multiple regression analyses to explain relationships between physiological signals and subjective self-reported levels of understanding of a second language listening task by using a visual analog scale (VAS) of 999 degrees. Mean contribution ratio of the logistic regression expressions was 0.72, and mean contribution ratio of the multiple regression expressions was 0.70. Power value of theta band of brain waves has a certain tendency to change according to the level of understanding. Accuracy of the regression expressions using VAS was the same or more than that of the four-level scale as our previous work.
