24 Mar Online Optical Illusion: Muller-Lyer Illusion
Psychological Article Explaining The Role of Perspective in Online Optical Illusions
“Seeing is believing.” Do you think that what ever you see is worth believing? Think again. There are a large number of online optical illusions that show what you see and not you think you see are not a one to one perfect match. The Muller-Lyer illusion is one such online optical illusion. This online optical illusion works on the principle of perspective. Psychological articles suggest that brain perceives an object at a farther point to be bigger than an object that is at a nearer point due to the effect of perspective.
In Muller-Lyer online optical illusion, the eye is deceived into thinking there is a difference from the original length of two lines when arrows are added pointing in different directions.
Which of the line two lines in this online optical illusion is longer? The second line with the outward arrow flaps definitely looks longer. However, the two lines are identical in length. Don’t believe us? Take a ruler to ascertain the lengths of both lines for yourself.
There are three main causes for the trick in this online optical illusion.
• The visual angle or the “perspective” gets smaller with distance. Therefore, the brain automatically perceives objects at farther distances to be bigger.
• We are familiar with lines that have inward flaps, such as corner of a building, which are relatively the nearest points of the overall object. Similarly, lines with outward flaps are found at the longer distance, as the farthest corner of a room. The brain perceives both the lines in this online optical illusion in relation to prior perceptions.
• In this online optical illusion, the brain perceives the line with outward flaps to be at a farther point as compared to the line with inward flaps. Consequently, the brain perceives the line with outward flaps to be longer.
Based on the principle of “perspective”, the deception of this online optical illusion is not limited to only the lines; as the visual deception may be any object or figure. Hence, many artists have used the principle of “perspective” to create various online optical illusions.
