Session means (standard deviations in parentheses) of the dependent measures for the four sessions.

p values are indicated for comparisons between the both groups of drivers. Pearson correlation coefficients are shown between the first and fourth session and the third and fourth session.已标注两组驾驶员组间比较的p值（p value），同时给出了首次与第四次实验环节、第三次与第四次实验环节间的皮尔逊相关系数（Pearson correlation coefficient）。
