概括
视觉适应和注意力影响整个视野的感知. 尽管适应强度有差异,但自愿和非自愿的注意力在视野午线上均地影响表现.
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
- 视觉感知 视觉感知 视觉感知
背景情况:
- 视觉感知在视野中不均,呈现水平垂直异构 (HVA) 和垂直午线不对称 (VMA).
- 视觉适应,一个管理感知资源的过程,在水平午线上比垂直午线更强.
- 视野午线上的差异视觉适应和空间注意力之间的相互作用尚未得到充分理解.
研究的目的:
- 调查内源性 (自愿) 和外源性 (非自愿) 隐蔽注意如何影响枢纽午线的视觉表现.
- 为了确定差异视觉适应是否调节横跨午线的隐藏空间注意力的影响.
主要方法:
- 实验采用了方向区分任务,使用中央或外围线索操纵内源或外源注意力.
- 在适应和非适应条件下,视觉表现在枢纽午线上被评估.
- 测量了对比度值以量化视觉性能.
主要成果:
- 在非适应条件下观察到典型的HVA和VMA.
- 与垂直午线相比,沿水平午线的视觉适应效应明显更强.
- 无论是内源的还是外源的注意力,都在所有枢纽午线上,无论适应如何,都在照顾的位置上同样提高了表现,在无人照顾的位置上表现受损.
结论:
- 内源性和外源性注意力对视觉表现的影响在整个枢纽午线上是统一的.
- 差异视觉适应不会改变空间注意力的午线均效应,尽管减少了内在视野不对称性.
- 这些发现突显了空间注意力在视觉场中的一致作用,即使底层的感知处理是通过适应调节的.

01:15Depth Perception and Spatial Vision
1.8K
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.

01:12Perceptual Constancy
1.2K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

In surveying, meridians are vital reference lines to measure directions and establish accurate land orientations. Meridians run from the north to the south poles, providing a stable framework for angular measurements and mapping. Meridians are fundamental in survey design, with the primary types being astronomic, magnetic, and assumed meridians. Each type offers distinct benefits and limitations, selected based on the project's scale and precision needs.The astronomic meridian is aligned with...
