Fatigue Study for Mariners
We built 21 cognitive quizzes for sailors.
Radar targets. Navigation lights. Cascading alarms. Timed decisions under pressure.
Each one takes about two minutes. Each one measures something different — reaction speed, pattern recognition, sustained attention, decision-making under load.
They're harder than you think.
Every response is anonymous. Every age group. Sailors and non-sailors. At sea and on land.
Your data goes straight into our fatigue research — helping us understand how tiredness changes the way you think and react.
