The student’s independent-samples t -test, by assessing the changes (i.e., post-task–pre-task) on each dimension and on the total scale of the SOFI, showed that they were of statistical significance between groups when looking at sleepiness [ t (19) = 2.10; p = 0.05; η 2 = 0.188] as well as of marginal significance in total fatigue [ t (19) = 1.89; p = 0.07; η 2 = 0.159].
