以目标为导向的控制依赖于构建一个将行动映射到特定结果的世界模型，使选择在结果的价值变化时保持适应性。然而，在复杂的环境中，这样的模型在计算上可能会变得笨拙。这个问题的一种解决方案是开发一种分层控制结构，在这种结构中，更复杂或更抽象的操作是从较简单的操作构建的。在这里，我们回顾的研究结果表明，目标导向行动的习得、评估和执行与分层模型的预测很好地吻合。我们描述了最近的证据表明，分级动作控制是在连接次级运动区和基底节的一系列反馈环路中实现的，并描述了这种结构如何不仅克服了维度问题，而且有助于解释动作序列的形成、动作组块以及目标定向动作与习惯之间的关系。
Goal-directed control depends on constructing a model of the world that maps actions onto specific outcomes, allowing choice to remain adaptive when the values of outcomes change. In complex environments, however, such models can become computationally unwieldy. One solution to this problem is to develop a hierarchical control structure within which more complex, or abstract, actions are built from simpler ones. Here we review findings suggesting that the acquisition, evaluation and execution of goal-directed actions accords well with predictions from hierarchical models. We describe recent evidence that hierarchical action control is implemented in a series of feedback loops integrating secondary motor areas with the basal ganglia and describe how such a structure not only overcomes issues of dimensionality, but also helps to explain the formation of actions sequences, action chunking and the relationship between goal-directed actions and habits.
