DESCRIPTION (Adapted from applicant's abstract): The human visual system obtains information about object depth from a large number of distinct cues. A full understanding of visual depth perception requires an understanding of how information provided by these cues is combined by our visual systems. Although nearly all theories of visual depth perception use the concept of cue reliability, we lack a good understanding of what this concept means, of how observers can measure cue reliability, and of what observers can do once they have measured it. The proposed research program places much importance on the need to understand observers' estimates of cue reliabilities, and on the need to understand how observers use these reliabilities during visual reliability judgments, and the roles that these factors play in experience-dependent adaptation of visual depth perception. Two types of experience-dependent adaptation are considered. Cue combination learning refers to the adaptation of the integration process that combines depth estimates based on individual cues into a single, composite depth estimate. Cue recalibration refers to the adaptation of depth interpretations of individual visual cues, such as adaptation of depth-from-motion estimates or adaptation of depth-from-texture estimates. The research program hypothesizes that observers regard a depth cue as reliable when: (i) depth estimates based on that cue are less variable than estimates based on other cues; or when (ii) depth estimates based on that cue are positively correlated with estimates based on other cues. It also hypothesizes that observers adapt their depth perception strategies so as to: (i) rely more heavily on reliable cues during cue integration; and to (ii) recalibrate depth judgments based on unreliable cues so that they more closely match those based on reliable cues.

描述（改编自申请人的摘要）：人类视觉系统 从大量不同的线索中获取有关对象深度的信息。 一个 充分理解视觉深度感知需要了解如何 这些线索提供的信息由我们的视觉系统结合起来。虽然 几乎所有视觉深度知觉理论都使用提示的概念 可靠性，我们缺乏对这个概念的含义以及如何实现的良好理解 观察者可以衡量线索的可靠性，以及观察者一旦发现线索可以做什么 已经测量过了。 拟议的研究计划非常重视了解的需要 观察者对线索可靠性的估计，以及了解线索可靠性的必要性 观察者在视觉可靠性判断中使用这些可靠性，并且 这些因素在依赖于经验的视觉适应中发挥的作用 深度感知。考虑两种类型的依赖于经验的适应。 提示组合学习是指适应整合过程 它将基于单独线索的深度估计结合成一个复合的 深度估计。提示重新校准是指深度的适应 对个人视觉线索的解释，例如适应 运动深度估计或纹理深度估计的适应。 该研究项目假设观察者认为深度线索是可靠的 当：（i）基于该线索的深度估计比估计的变量更小 基于其他线索；或者当 (ii) 基于该提示的深度估计是 与基于其他线索的估计呈正相关。 它还假设 观察者调整他们的深度感知策略，以便：（i）更多地依赖 在提示整合过程中高度依赖可靠的提示；以及 (ii) 重新校准深度 基于不可靠线索的判断，以便它们与基于不可靠线索的判断更接近 依靠可靠的线索。
