Experimental design (A) and procedures during experimental sessions (B). Participants were randomly assigned to two groups in a crossover fashion toperform two types of fatigue-inducing n-back test experiments on separate days.The time interval between each experiment was 1 week. Each experimentconsisted of four 30-min fatigue-inducing mental task sessions and twoevaluation sessions performed just before and after the four fatigue-inducingsessions.
