Illusion is a false perception of an object, which, unlike hallucination occurs in this object. However, misperceptions are considered only if delusions modiss are valid for a large number of individuals. Illusions common to all individuals with a normal psychophysiological state laws are determined modiss by itself modiss forming perceptions. In what follows, we shall consider optical illusions.
1. What number do you see? Those who see colors well, I can see three basic colors: red, green and blue. In this way you can see the number 74. Those who suffer from color blindness (red and green confused), I see in this case the number 21.
2. Can you find your blind spot, if up in your face, arms stretched, this page. Close or cover the left eye and right eye look at the green circle on the left. Zoom sheet toward you slowly until the red circle disappears. At that time you got in that place of the retina where the optic nerve starts - blind spot.
3. To obtain white light, enough to mix three colors: red, green and blue. These are the basic colors. The color white is a color combination. The colors yellow, purple and magenta are obtained in combination with 2 colors base- they are secondary modiss colors.
The most famous and studied illusion of length is probably the Muller-Lyer illusion, created by German psychiatrist Franz Muller-Lyer in 1889. Which of horizontal segments AB and CD seem longer? Although the visual system indicates the segment AB as long, in fact, segments are equal in length if you measure.
To achieve the illusion contributes oblique lines. A Muller-Lyer illusion explanation is that the transition from two-dimensional to the three-dimensional perception is incorrect. Because of the oblique lines directed outward human optic device interprets the segment AB as being out of sight to the segment CD, which, because lines inward seems closest. The human eye can not appreciate the size of an object modiss without regard to the distance; Therefore, although two objects result equal retinal projections, we tend to consider more distant object appears larger. modiss
Another illusion is known Ponzo illusion, named after Italian psychologist Mario Ponzo. As Muller-Lyer illusion and the two horizontal lines appear unequal in length, although in reality are equal. The explanation of this illusion is related to depth perception. To the human eye, slanting lines create a feeling of depth, which leads to different assessments of the distances to the two segments (segment above seems more distant). However, the images formed on the retina of the two segments are equal.
In the figure below is represented Zollner illusion: a square appears to be trapezoidal because of the background that is superimposed. Again comes the feeling of depth, created by oblique lines - top side of the square seems more distant, and therefore greater.
An example of large-scale illusion of length was built by the Greeks 2500 years ago. It is the Parthenon, a temple famous Greek that seems to be built perfectly straight angles. But this is an illusion, because the Parthenon presents no perfect right angle. To offset the negative effects of linear perspective which would have led to the image of a temple crooked and bent, the architects built the Parthenon columns slightly inwards. In addition, they built basic and other horizontal elements, the higher the center to the edges, and the columns were "swollen" a little around the middle.
