Mental Fatigue and Industrial Work Performance

"A modified Stroop task of approximately 60 min will be used in order to induce mental fatigue (MF). This will be based on their performance during the max test that was conducted during the familiarization session. In this task, which will be partitioned in 4 blocks of 468 stimuli, four colored words (rood, blauw, groen and geel) will be presented one at a time on a computer screen. The participants will be required to indicate the color of the word, ignoring the meaning of the word itself."

In the control task subjects will have to watch a documentary of 60 min on the same computer screen as the one used for the experimental trial. In order to avoid under- and over-arousal the subjects will have the opportunity to choose between several documentaries as proposed by the research team.
