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 从大量不同的提示中获取有关对象深度的信息。 一个 对视觉深度感知的完全理解需要了解 这些提示提供的信息由我们的视觉系统组合。虽然 几乎所有视觉深度感知理论都使用提示的概念 可靠性，我们对这个概念的含义缺乏很好的了解 观察者可以衡量提示可靠性，以及观察者一旦他们可以做什么 已经测量了它。 拟议的研究计划非常重视了解 观察者对提示可靠性的估计以及了解如何了解 观察者在视觉可靠性判断过程中使用这些可靠性，以及 这些因素在视觉的依赖性适应中起着这些因素的作用 深度感知。考虑了两种依赖经验的适应性。 提示组合学习是指整合过程的适应 将基于单个线索的深度估计结合到一个复合材料中 深度估计。提示重新校准是指深度的适应 对单个视觉提示的解释，例如适应 深度估计的深度估计或深度从文本估算的适应性。 研究计划假设观察者认为深度提示是可靠的 时间：（i）基于该提示的深度估计值不如估计值 基于其他提示；或（ii）基于该提示的深度估计值 基于其他提示，与估计值呈正相关。 它也假设 观察者适应了他们的深度感知策略，以：（i）依靠更多 在提示整合过程中，大量了解可靠的提示；并（ii）重新校准深度 基于不可靠的提示的判断，以使它们更紧密地匹配这些基于的 关于可靠的提示。
