预测未来事件的能力使生物能够检测、建模和操纵其与环境相互作用的因果结构。行为实验表明，学习是由对未来显着事件（例如奖励和惩罚）的期望变化驱动的。生理学工作最近通过识别灵长类动物的多巴胺能神经元来补充这些研究，其波动的输出显然表明对未来显着和奖励事件的预测发生变化或错误。总而言之，这些发现可以通过自适应优化控制的定量理论来理解。
The capacity to predict future events permits a creature to detect, model, and manipulate the causal structure of its interactions with its environment. Behavioral experiments suggest that learning is driven by changes in the expectations about future salient events such as rewards and punishments. Physiological work has recently complemented these studies by identifying dopaminergic neurons in the primate whose fluctuating output apparently signals changes or errors in the predictions of future salient and rewarding events. Taken together, these findings can be understood through quantitative theories of adaptive optimizing control.
