Question

Quizplus · Accepted Answer

The self-regulatory resource model suggests individuals have a limited amount of self-control or willpower, similar to how a fuel tank has a limited amount of gas. As people use their self-regulatory resources to make decisions, resist temptations, or regulate their emotions, this "fuel tank" of self-control becomes depleted and may need to be recharged through rest or replenishment.
