Onetotech.com – Take a good look at the image above and focus on the point in the middle. Do not blink, In less than half a minute, you may notice that the pattern is fading. This is The Troxler Effect of Optical Illusion.
Lighter colors and shapes on the edges will be the first to disappear. Within a minute or so, all images are lost and leaving only a clean white or gray space with no pattern.
When you blink or attention is distracted, the pattern as you see at the beginning will reappear.
The Troxler Effects of Optical Illusion Explanation
His name is The Troxler Effects of Optical Illusion, taken from his creator who was a Swiss physician and philosopher who lived in the early 19th century named Ignaz Paul Vital Troxler.
Around 1804, Troxler found something interesting. As he focuses his eyes at one point, other elements in the same visual field will slowly fade and disappear.
Basically, The Troxler Effects of Optical Illusion find not really eliminating the image as we continue to see it.
Reported by Science Alert, Wednesday (11/4/2018), to understand this optical illusion let us get acquainted with saccade. Saccade is a subconscious movement made by the human eye, even when we are not focused.
Fast eye movement allows the retina with all the light-sensitive cells to scan high resolution visual fields. This is why when the retinal focus sees a small point in the visual field. The retinal light sensitive cells will only focus on something that does not change and slowly becomes insensitive to the stimulus.
Meanwhile, IFL Science proclaimed on Tuesday (10/4/2018), the picture is just an illustration of how the brain overcome the thousands of sensations that continue to be encountered.
Phenomenon is Known as a Selective Process
This phenomenon is known as a selective process. Unwittingly, the brain filters out the foreign information so we just focus on the important things and will decide on the form of unimportant information.
When the brain ignores the unchanging visual stimuli. The colors in the image above seem to fade and fill with the white color around it, “We may not realize something like this happens because the eyes and environment are constantly changing,” says psychology professor. Derek Arnold from Queensland University to The Verge, Monday (9/4/2018).
This illusion is unusual because it directs our attention to one thing from so much attention and is supported by a blurry and faded image. Selective processing may be more noticeable when it comes to other senses.
This causes you to rarely smell perfume in a minute or two after use and you also do not realize how your clothes look when worn.
This phenomenon also explains why we do not notice the existence of our noses. Here are some The Troxler Effects of Optical Illusion to distract you:
