The Cognitive Control Account of Effort

At first glance, the type of effort required to solve a chess puzzle and run a marathon seems fundamentally different. I argue they’re not. I present a novel account of effort in which all effort is explained through the lens of a domain-general psychological mechanism, cognitive control. I outline how effort choice and execution take place, emphasizing the role of cognitive control, a mental process by which all effort—mental and bodily— is made. I present four arguments that convergently provide strong support for the cognitive control account. Additionally, I examine the implications of this unified theory of effort for philosophical discussions in ethics, philosophy of mind, and action theory.
