概括

成年人可以被训练来区分视觉感知的眼睛起源,即使单眼通道强度没有变化. 这表明,一个高级别的决策过程影响了眼睛的起源判断.

科学领域:

视觉感知视觉感知视觉感知
神经科学是一个神经科学.
认知心理学认知心理学

背景情况:

仅仅通过视网膜信号来确定眼睛的起源是具有挑战性的.
感知眼的起源歧视往往依赖于上下文的线索.
外源的注意力可以提高单眼刺激的表现.

研究的目的:

调查成年人是否可以被训练来区分视觉感知的眼睛起源.
评估训练的有效性是否取决于单眼通道强度.
探索元认知在原始眼睛判断中的作用.

主要方法:

注意力向前养培训与自愿注意力.
在训练期间提供双筒镜线索,以指示目标眼的起源.
持续的闪光抑制用于测量单眼目标信号强度.
收集对原产地鉴定判断的信任评级.

主要成果:

经过培训后,眼睛原点歧视的表现得到了改善.
自愿注意力没有显著改变单眼通道信号强度.
信任评级显示出与绩效相似的改善模式.
通过连续闪光抑制,没有通过线索观察到信号强度的调制.

结论:

培训提高了眼睛的起源歧视能力.
提高的业绩和信心表明了高级别的决策机制.
这种机制很可能利用微妙的感官线索,如亮度或对比差异.
对眼睛起源信息的元认知访问得到了信心评级的支持.

关键词:

Color Vision

Color Vision

Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
