Note. EF_fs, factor score of executive ability; Read_fs, factor score of reading ability; L_FEF, percent signal change of FEF (10 mm sphere centered on [-36, -6, 50]) from the reading task; 0-back_acc, accuracy of 0-back trial; 2-back_acc, accuracy of 2-back trial; Read_acc, accuracy of picture judging trials in the reading task; Read_rpt, hit rate of repeated trials in the reading task.
