Yerkes and Dodson-law
Psychologists Robert Yerkes and John Dodson developed a first version of the pressure performance curve back in 1908. They used it to show the relationship between arousal (pressure) and performance for Yerkes-Dodson Law. Our version, above, incorporates several fresh ideas that make it a useful tool for understanding, and managing, pressure in the workplace.
You can see from the graph that pressure runs along the x-axis horizontally from low to very high. Performance is along the y-axis from low to high. We’ve segmented the bell-shaped pressure performance curve into zones of various colours. These colours represent a traffic light warning system. Green is good; amber is caution; and red is bad.
