Any object can have an ambiguous representation and can be mistakenly categorized into the wrong groups without sufficient memory recognition of an object. This finding suggests that prior experience is necessary for proper perception. [15] Studies have been done with the use of Greebles to show the role of memory in object recognition. [6]
The two orange circles are exactly the same size; however, the one on the right appears larger. Ehrenstein illusion The Ehrenstein illusion is an optical illusion studied by the German psychologist Walter Ehrenstein in which the sides of a square placed inside a pattern of concentric circles take an apparent curved shape.
Stereoscopy creates the impression of three-dimensional depth from a pair of two-dimensional images. [5] Human vision, including the perception of depth, is a complex process, which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make sense of the raw information.
If the patterns received by the two eyes are similar enough, the brain will consider these two patterns a match and treat them as coming from the same imaginary object. This type of visualization is known as wall-eyed viewing , because the eyeballs adopt a wall-eyed convergence on a distant plane, even though the autostereogram image is ...
Linear or point-projection perspective (from Latin perspicere 'to see through') is one of two types of graphical projection perspective in the graphic arts; the other is parallel projection. [citation needed] [dubious – discuss] Linear perspective is an approximate representation, generally on a flat surface, of an image as it is seen by the eye.

You may have heard the adage, “A picture is worth a thousand words.” In that same vein, medical illustrators use pictures to teach complex scientific concepts.
Visual thinking has been described as seeing words as a series of pictures. [ 2 ] [ 3 ] It is common in approximately 60–65% of the general population. [ 1 ] " Real picture thinkers", those who use visual thinking almost to the exclusion of other kinds of thinking, make up a smaller percentage of the population.
