The relationship between stress (or arousal) and performance is often represented graphically. The X-axis typically shows increasing levels of stress, while the Y-axis shows the level of performance.
Research, often summarized by the Yerkes-Dodson Law, suggests:
This relationship typically forms an inverted U-shaped curve on the graph.
The highest point on the performance curve represents the best performance. This peak occurs when the stress level is moderate, not too low and not too high. Therefore, on the graph:
Consequently, the best performance is expected when stress levels are moderate, corresponding to the middle portion of the X-axis.
