Understanding the psychological computations underlying motivation can shed light onto motivational constructs as emergent phenomena. According to Murayama and Jach, reward-learning is a key candidate mechanism. However, there's no such thing as a free lunch: Not only benefits (like reward), but also costs inherent to motivated behaviors (like effort, or uncertainty) are an essential part of the picture.
理解动机背后的心理计算可以揭示动机结构作为一种涌现现象的本质。根据村山和贾赫的观点，奖励学习是一个关键的候选机制。然而，天下没有免费的午餐：不仅益处（如奖励），而且动机行为所固有的成本（如努力或不确定性）都是这幅图景的重要组成部分。
