概括

视觉幽灵创造虚幻的运动感知. 这项研究发现,虽然幻觉感知增强了运动后效应 (MAE),但低水平的运动适应是间隙区域中MAE的主要驱动因素.

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.
心理物理学的精神物理.

背景情况:

运动感知是建设性的,正如视觉幻象幻象所示.
视觉幻影被认为是诱导格子之间的间隙中漂流的条纹.
以前的研究表明,诱导幻象的网格可以在隙中引起运动后效应 (MAE).

研究的目的:

调查差距区域的MAE是否是由视觉幻影本身的感知引起的.
为了比较由幻象诱导格子引起的MAEs的强度与对照刺激.

主要方法:

通过使用幻象诱导格子和匹配的控制刺激来评估MAE.
操纵感应网格的亮度:最暗的部分与生动的幽灵相匹配,平均亮度与控制器的背景相匹配.
通过物理对比测量MAE强度和调制.

主要成果:

幻影和控制感应器都唤起了相反方向的运动感知.
动态MAE与对照组相比,对于幻象诱导剂略强一些.
MAE 更多的是通过控制诱导剂来调节对比度,而由幻象诱导剂来调节较少.

结论:

低级运动适应显著促进差距区域的MAE.
幻觉进一步调节了运动适应的大小,暗示了结合效应.

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.
