概括

时间再校准调整了我们对何时发生行动及其感官反的感知,即使视觉信息延迟. 这项研究表明,这种适应适用于眼动,改善视觉处理.

科学领域:

神经科学是一个神经科学.
认知科学认知科学
视觉感知视觉感知视觉感知

背景情况:

准确的因果关系推断依赖于行动和感官结果之间的精确时间关系.
时间重新校准,即对延迟的感觉反进行感知调整,已知在各种感觉运动领域.
它的扩展到眼运动和随机感官事件仍然在很大程度上未被探索.

研究的目的:

调查时间重新校准机制是否适用于双眼运动及其相关的感觉事件.
确定视觉系统如何适应眼动和视觉后果之间的时间延迟.

主要方法:

参与者进行了横向的动,触发了具有可变延迟的闪光.
收集了相对于saccade偏移的闪光时间的感知报告.
在各种视觉线索下以及在一次重复播放条件下评估了重新校准效应.

主要成果:

暴露于连续的萨卡德闪延迟改变了感知,延迟闪通常被认为是在萨卡德闪期间发生的.
这种重新校准对于视觉背景 (背景,目标连续性) 的变化来说是强大的.
萨卡德执行至关重要,因为重播条件显示了显著较小的重新校准效应.

结论:

视觉系统在重新校准眼睛运动和感官反之间的感知时间方面表现出显著的适应能力.
这种视觉运动时间重新校准机制可能有助于自然视觉的感知稳定性.
与视觉输入的动态重新调整saccades在时间变化中帮助稳定的感知.

Depth Perception and Spatial Vision

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.
