Inclusion criteria

Inclusion criteria: - 18-40 years old - male or female - Presence of a written declaration of consent

Exclusion criteria

Exclusion criteria: - Participation in CoCo Study 2015 - BMI >30 - unable to speak German - any medication with an influence on the examination parameters - drug addiction, smoker - visual and hearing problems impairing eye movement measurement or communication - any other condition which, in the opinion of the physicians performing the test, makes the subject appear unsuitable (e.g. claustrophobia) - pregnancy - Suspected sleep apnea syndrome (STOP-Bang and ESS) - extreme manifestations of relevant personality traits (FPI) - Tendency to depression (BDI)

Design outcomes

Primary

Measure	Time frame
Fatigue affects the reaction time in the monitoring task of a control station simulation to a lesser extent when working together in the team than with individual task processing. The primary result variable is the reaction time, in which the test subjects identify critical incidents in a control station simulation and make decisions.	—

Secondary

Measure	Time frame
Fatigue affects the accuracy in the monitoring task of a control station simulation to a lesser extent when working together in the team than with individual task processing. Fatigue affects the reaction time in the diagnostic task of a control station simulation less when working together in a team than when working on individual tasks. Fatigue impairs the accuracy of the diagnostic task of a control station simulation less strongly in team collaboration than in individual task processing. With regard to the process variable gaze movement, teamwork is defined under fatigue, the synchronicity of the eye movements is less than assumed in the rested condition. With regard to the process variable communication, it is expected that the subjects exchange less information and share conclusions during fatigue than during rest. In situations with a conflict of objectives, fatigue is more likely to lead to decisions being made for oneself than for the team.	—
