Neuroscientist Dr. David Wong argues that willpower is a limited resource that can be depleted through use, like a muscle that tires.

readingWhich experimental finding would best support Wong's depletion model?
A
Some tasks require effort
B
Participants who resisted temptation on one task showed 40% less persistence on subsequent unrelated tasks; glucose consumption correlated with self-control; and mental rest restored performance
C
People sometimes give up
D
Motivation varies
Correct Answer: B
Choice B is the best answer. Sequential depletion + biological mechanism (glucose) + replenishment proves limited resource model.
💡 Strategy: Resource metaphors need depletion, substrate, and recovery evidence.
