Yerkes-Dodson Law: Pressure and Performance
The pressure-performance curve explains why more urgency is not always better.
What is it?
The Yerkes-Dodson law describes a curved relationship between arousal and performance. Low arousal can feel sleepy or unmotivated. Moderate arousal can sharpen attention. High arousal can make thinking noisy and brittle.
People often draw the idea as an inverted U. The useful zone is somewhere in the middle.
Simple example
A small deadline might help you start a simple task. A huge deadline, poor sleep, and unclear instructions can make the same task feel impossible.
This is why pressure can feel motivating in one situation and paralyzing in another. The task difficulty and your current state both matter.
Why it matters
The model pushes back against the idea that stress is always the answer. For routine tasks, a little urgency may help. For complex tasks, too much pressure can harm memory, creativity, and flexible thinking.
Sometimes the best performance move is not more force. It is clearer steps, a calmer setting, or a real break.
Try it on CurioLab
Reaction Speed Test and Stroop Color Challenge both show how alertness and attention interact. A faster score is not always about trying harder; it can be about being in a good arousal zone.
The Stress & Recovery Profile can help you notice when your system may need recovery rather than more pressure.
Keep in mind
The curve is a simple model, not a complete explanation of stress. Long-term stress, panic, or burnout deserves support beyond productivity tips.
