The right decision today may be the wrong decision tomorrow. We live in a world in which expectations, contingencies, and goals continually evolve and change. Thus, decisions do not occur in isolation but rather are tightly embedded in these streams of temporal dependencies. Accordingly, even relatively straightforward visual decisions must take into account not just the immediate sensory input but also past experiences and future goals and expectations. Here, we evaluate recent progress in understanding how the brain implements these dependencies. We show that visual decision-making relies on mechanisms of evidence accumulation and commitment that have been studied extensively under relatively static, isolated conditions but in general can operate much more flexibly. A deeper understanding of these mechanisms will require identifying the principles that govern this flexibility, which must operate across different timescales to produce effective decisions in uncertain and dynamic environments.

不确定和动态世界中的视觉决策。

今天的正确决定可能是明天的错误决定。我们生活在一个期望，突发事件和目标不断发展变化的世界中。因此，决策不是孤立地发生的，而是紧密地嵌入到这些时间依赖性流中。因此，即使是相对直接的视觉决策也必须不仅考虑立即的感觉输入，而且还要考虑过去的经验以及未来的目标和期望。在这里，我们评估在了解大脑如何实现这些依赖性方面的最新进展。我们表明，视觉决策依赖于在相对静态，孤立的条件下进行了广泛研究的证据积累和承诺机制，但总的来说可以更加灵活地运作。
