我们如何能不知道的赤字在我们的(单眼)视野,相当于76满月的大小的问题,检查。一种研究风斑上和附近的运动图像响应的新方法已经被发现。计算机生成的直线的图像随着时间的推移而变长并穿过盲点,其图像被视为比穿过盲点之外的类似平行线的图像短。这种感知到的长度差异对应于盲点的实际宽度。我们对盲点和seotomata的无知通常被描述为涉及某种形式的“填充”过程。皮层感受野位置的快速变化。最近发现的响应于稳定化图像而发生的图像模糊,可以提供用于从另外分散注意力的稳定化图像区域(诸如血管阴影和临床暗点)的感知中去除的一般填充机制。
The question of how we can be unaware of the deficit in our (monocular) visual field, equivalent in size to 76 Full moons, is examined. A new method of investigating the response to moving images on and near the Wind spot has been found. The image of a computer‐generated line, which is made to lengthen with time and pass over the blind spot, is seen as shorter than that of a similar, parallel line which passes outside the blind spot. This perceived difference in length corresponds to the actual width of the blind spot. Our unawareness of blind spots and seotomata is often described as involving some form of ‘filling in’ process. The rapid variation in cortical receptive field site. recently found lo occur in response to stabilized images, may provide a general filling‐in mechanism for the removal from perception of otherwise‐distracting, stabilized image regions (such as the shadows of blood vessels and clinical scotomata).
