For over 100 years, eye movements have been studied and used as indicators of human sensory and cognitive functions. This review evaluates how eye movements contribute to our understanding of the processes that underlie decision-making. Eye movement metrics signify the visual and task contexts in which information is accumulated and weighed. They indicate the efficiency with which we evaluate the instructions for decision tasks, the timing and duration of decision formation, the expected reward associated with a decision, the accuracy of the decision outcome, and our ability to predict and feel confident about a decision. Because of their continuous nature, eye movements provide an exciting opportunity to probe decision processes noninvasively in real time.

眼动作为决策的窗口

一百多年来，人们一直在研究眼球运动并将其用作人类感觉和认知功能的指标。这篇综述评估了眼球运动如何有助于我们理解决策过程。眼动指标表示信息积累和权衡的视觉和任务环境。它们表明我们评估决策任务指令的效率、决策形成的时间和持续时间、与决策相关的预期奖励、决策结果的准确性以及我们预测决策和对决策充满信心的能力。由于其连续性，眼球运动提供了一个令人兴奋的机会来实时无创地探索决策过程。
