What law demonstrates the relationship between stress and performance associated with sympathetic nervous system activation?

The Introverted-U Law illustrates the relationship between stress (or arousal) and performance, particularly highlighting how performance can improve with a certain level of stress or arousal up to an optimal point. Beyond this point, further increases in stress may lead to a decline in performance, establishing an inverted U-shaped curve.

This law is particularly relevant in contexts where sympathetic nervous system activation is involved, as increased arousal from stress can initially enhance focus and energy, contributing to improved performance. However, as stress levels continue to rise beyond an individual's optimal threshold, it can lead to anxiety and decreased performance, effectively showcasing the dualities of stress and performance outcomes.

In contrast to this law, the other options do not accurately represent the established understanding of the relationship between stress and performance, particularly in the context of sympathetic nervous system activation.
