Cognitive and cortical mechanisms of trans-saccadic motion perception

我的研究项目调查了一种基本的日常有意识视觉体验的潜在机制：尽管每次我们移动眼睛时，视觉场景中物体的位置发生了戏剧性的变化，但我们对稳定和连续的视觉世界的感知。我们使用被称为扫视的快速眼球运动扫描周围环境。我们通常每秒大约进行3-5次扫视。在每一次扫视中，整个世界的图像在我们的视网膜上移动，我们周围的物体移动到不同的视网膜位置。然而，这些物体并不是随着我们眼睛的移动而跳来跳去的，它们通常被认为在空间上是稳定的。这是所谓的跨眼跳知觉中知觉连续性的一个例子，表明视觉系统有机制通过考虑眼跳过程中凝视的变化来跟踪物体在空间中的位置。大多数关于跨眼跳知觉的知觉连续性的研究都集中在大脑如何跟踪

My research program investigates the underlying mechanisms of a fundamental everyday conscious visual experience: the perception of a stable and continuous visual world despite dramatic changes to the location of objects in a visual scene every time we move our eyes. We scan our surroundings using rapid eye movements called saccades. We typically make about 3-5 saccades per second. During each saccade the entire image of the world shifts across our retina and objects in our surroundings shift to different retinal locations. However, rather than perceiving these objects as jumping around as our eyes move they are normally perceived as spatially stable in the world. This is an example of perceptual continuity in so-called trans-saccadic perception, and suggests that the visual system has mechanisms for keeping track of where objects are in space by taking into account the change in gaze during saccades. Most research on perceptual continuity in trans-saccadic perception has been focused on how the brain keeps track of the locations of
