选择的动机理论关注目标价值观和强化强度的影响来解释行为。相比之下，人们对行动的成本（如付出的努力）如何影响行动的决定知之甚少。基于努力的决策解决了我们如何基于行动和目标价值的整合来做出行动选择。在这里，我们回顾行为和神经生物学数据的代表性努力的行动成本，以及如何影响决策。尽管生物体会付出努力来获得所需的回报，但对所需努力的量有着惊人的敏感性，因此对行动的净偏好会随着努力成本的增加而减少。我们讨论了神经递质多巴胺（DA）对克服反应成本和提高动物的努力行动的动机的贡献。我们还考虑了大脑结构的贡献，包括基底神经节和前扣带皮层，在内部产生的行动，涉及翻译的奖励期望到努力的行动。
Motivational theories of choice focus on the influence of goal values and strength of reinforcement to explain behavior. By contrast relatively little is known concerning how the cost of an action, such as effort expended, contributes to a decision to act. Effort-based decision making addresses how we make an action choice based on an integration of action and goal values. Here we review behavioral and neurobiological data regarding the representation of effort as action cost, and how this impacts on decision making. Although organisms expend effort to obtain a desired reward there is a striking sensitivity to the amount of effort required, such that the net preference for an action decreases as effort cost increases. We discuss the contribution of the neurotransmitter dopamine (DA) toward overcoming response costs and in enhancing an animal's motivation toward effortful actions. We also consider the contribution of brain structures, including the basal ganglia and anterior cingulate cortex, in the internal generation of action involving a translation of reward expectation into effortful action.
