概括

视觉稳定性在眼睛运动 (摇动) 中依赖于对象位置绑定. 这项研究表明,被萨卡德所准的物体与其他物体不同,被稳定的空间坐标所束. 这凸显了萨卡德目标在视觉稳定中的作用.

科学领域:

认知神经科学认知神经科学
视觉感知视觉感知视觉感知
人类视觉人类视觉

背景情况:

在眼睛运动 (摇摆) 过程中保持视觉稳定性需要跟踪物体位置.
对象位置绑定通常使用视网膜 (以眼睛为中心) 坐标用于外围项目.
在现实世界中,往往是指向感兴趣的对象.

研究的目的:

调查萨卡德目标状态是否会影响跨萨卡德对象位置绑定的参考框架.
为了确定萨卡德所准的物体是否与空间位点 (以世界为中心) 坐标相结合.
探讨对萨卡德目标的空间位相结合的生态相关性.

主要方法:

使用了修改后的空间一致性偏差范式.
参与者通过saccades来判断对象的身份.
萨卡德指向的是对象的位置 (萨卡德目标) 或其他地方.

主要成果:

对象位置绑定主要是 retinotopic 对于非目标的saccades (saccade-elsewhere,saccade-away).
萨卡德目标对象表现出了视网膜和空间对象位置绑定.
萨卡德目标状态特别使额外的空间位素结合成为可能.

结论:

萨卡德目标对象还可以通过萨卡德连接到稳定的空间坐标.

Inertial Frames of Reference

Inertial Frames of Reference

Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...

Non-inertial Frames of Reference

Non-inertial Frames of Reference

A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...
