Study Groups

Mental fatigue - No Robot
During a 15 minute trial, the participant will relocate a box of 5 kilograms between ground level and shoulder height. During this task, the participants are asked to perform the serial seven task, continuously subtracting seven from a given number between 900 and 950. Afterwards, the participant will perform a 60- minute Stroop task and is asked to repeat this abovementioned physical dual-task.
Mental fatigue (Stroop task)
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.
Mental fatigue - Exoskeleton
During a 15 minute trial, the participant will wear the Laevo exoskeleton and will relocate a box of 5 kilograms between ground level and shoulder height. During this task, the participants are asked to perform the serial seven task, continuously subtracting seven from a given number between 900 and 950. Afterwards, the participant will perform a 60- minute Stroop task and is asked to repeat this abovementioned physical dual-task.

No Mental fatigue - No Robot
During a 15 minute trial, the participant will relocate a box of 5 kilograms between ground level and shoulder height. During this task, the participants are asked to perform the serial seven task, continuously subtracting seven from a given number between 900 and 950. Afterwards, the participant will watch a 60- minute neutral documentary and is asked to repeat this abovementioned physical dual-task.
Control (documentary)
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.
