Information Integration Across Eye Movements

视觉世界所包含的信息比我们所能感知的要多 in a single单glance一瞥. 为了弥补这种状况，我们 使眼睛和头部运动，看感兴趣的物体， 我们会逐渐在脑海中构建一个 从这些连续的观点。 我们的眼睛是通过 快速运动，称为扫视，由短暂的 一段时间，称为固定，在此期间，眼睛是 别动 从逻辑上讲， 产生极其破坏性的视觉输入模式的活动 对于感知，一系列静止的，清晰的图像， 世界，交替与暴力扫描的信息期间， 扫视 当然，我们的知觉经验并不 与这样的交替序列相对应。 而是 由清晰、连续的大断面全景组成 在视觉环境中，物体保持稳定 空间 这种视觉输入的性质与 我们非凡体验的本质是伟大的体验之一 神秘的感知研究，一个神秘的，仍然是 大部分未解决。 该研究项目将调查 记忆的特征或负责 整合眼球运动中的信息， 对视觉世界的连贯感知， 体验. 特别是，研究将集中在 能力、时间进程和代表性格式 回忆人们在观看视觉显示时， 行动受到监控。 当检测到眼球运动时， 视觉显示将消失，观察者对此的记忆也将消失， 显示将被评估。 例如，观察者可以指示 第二显示器是否与第一显示器相同或不同， 第一次显示，或者可能试图报告一些特定的 显示器中显示的信息。 这些响应 将显示原始视图的哪些方面存储在 记忆和维持整个眼球运动。 通过改变 量和视觉特征的信息在 通过改变存储器的定时和性质， 通过眼动测试，研究将揭示 许多信息在眼球运动中被保留，它能保留多久？ 在记忆中持续存在，它的记忆有多详细 表示. 对稳定和连续的视觉环境的感知 眼睛位置的变化， 科学家们已经研究了世纪。 这项研究将使我们能够 在解决这个难题上取得进展。此外，研究 将提供有关空间表示的重要信息 和空间认知，可能与 阅读的研究和眼科疾病的研究， 有时伴随着知觉的不稳定。

The visual world contains more information than we can perceive in a single glance. To compensate for this state of affairs, we make eye and head movements to look at objects of interest, and we gradually construct a mental representation of the environment from these successive views. Our eyes scan the world by means of rapid movements, called saccades, that are separated by brief periods of time, called fixations, during which the eyes are still. One might logically expect this pattern of eye movement activity to produce a terribly disruptive pattern of visual input for perception, a sequence of stationary, clear images of the world, alternating with violent sweeps of information during the saccades. Our perceptual experience, of course, does not correspond to such an alternating sequence at all. Rather, it consists of clear, continuous, panoramic views of large sections of the visual environment, with objects remaining stable in space. This mismatch between the nature of the visual input and the nature of our phenomenal experience is one of the great mysteries in the study of perception, a mystery that is still largely unsolved. This research project will investigate the characteristics of the memory or memories responsible for integrating information across eye movements to yield the coherent perception of the visual world that we ordinarily experience. In particular, the research will focus on the capacity, time-course, and representational format of these memories. People will view visual displays while their eye movements are monitored. When an eye movement is detected, the visual display will disappear and the observer's memory for that display will be assessed. For example, the observer may indicate whether a second display is identical to or different from the first display, or may attempt to report some particular information that was present in the display. These responses will reveal what aspects of the original view are stored in memory and maintained across an eye movement. By varying the amount and the visual characteristics of the information in the display and by varying the timing and the nature of the memory test following the eye movement, the research will reveal how much information is retained across eye movements, how long it persists in memory, and how detailed is its memory representation. The perception of a stable and continuous visual environment across changes in eye position has puzzled and intrigued scientists for over a century. The research will allow us to make progress in solving this puzzle. In addition, the research will provide important information about spatial representation and spatial cognition in general, with possible relevance to the study of reading and to the study of oculomotor disorders that are sometimes accompanied by perceptual instability.
