86. People make mistakes when they are under stress

• THE YERKES-DODSON LAW
• Research on stress shows that a little stress (arousal) can help you perform a task, while too much stress degrades performance

Arousal (stress)

• The Yerkes-Dodson law states that performance increases with physiological mental arousal, but only to a point.
• When levels of arousal become to high, performance decreases.
• Research shows that the optimal amount of stress/arousal depends on the difficulty of the task.

The tunnel action

• When too much arousal people fall into an action called the "tunnel action" when they tent to do something over an over still knowing that they won't succeed.
