According to the Yerkes-Dodson Law, what is the expected impact of very low arousal on performance?

The Yerkes-Dodson Law posits that there is an optimal level of arousal for peak performance, typically resembling an inverted U-shape curve. When arousal is too low, individuals may experience lack of motivation, decreased focus, and overall poor engagement with the task at hand. This low arousal state can lead to difficulties in concentration, making it challenging to perform effectively, as the mental and physical resources required to complete tasks are underutilized. As a result, performance is often suboptimal in states of very low arousal, aligning with the notion that under-stimulated individuals perform poorly due to their inability to engage adequately with the task. Thus, it is understood that very low arousal leads to poor performance rather than facilitating or enhancing it.
