It was taken up by Wilhelm Wundt, widely regarded as the founder of experimental psychology, and is now universally used. [ 1 ] [ 2 ] [ 3 ] That by 1972 the first edition of Robinson's book devotes 100 closely printed pages and over 180 figures to these illusions attests to their popularity.
The Rubin vase illusion, where it is ambiguous which part is the figure and which the ground Shapes which can be read as a word once the viewer recognises them as being the isolated negative spaces of a word. Figure–ground organization is a type of perceptual grouping that is a vital necessity for recognizing objects through vision.
The MIT Encyclopedia of the Cognitive Sciences explains the illusion as an effect of "size and shape constancy [which] subjectively expand[s] the near-far dimension along the line of sight." [4] It classifies Shepard tables as an example of a geometrical illusion, in the category of an "illusion of size." [4]

A block design test is a subtest on many IQ test batteries used as part of assessment of human intelligence. It is thought to tap spatial visualization ability and motor skill . The test-taker uses hand movements to rearrange blocks that have various color patterns on different sides to match a pattern.
Example problem based on Shepard & Metzlar's "Mental Rotation Task": are these two three-dimensional shapes identical when rotated? Mental rotation is the ability to rotate mental representations of two-dimensional and three-dimensional objects as it is related to the visual representation of such rotation within the human mind. [1]
Indeed, some of their 'laws' of perceptual organisation today sound vague and inadequate. What is meant by a 'good' or 'simple' shape, for example?" [47] One historian of psychology, David J. Murray, has argued that Gestalt psychologists first discovered many principles later championed by cognitive psychology, including schemas and prototypes ...
Two classes of shape-based visual identification that are not done through geon representations, are those involved in: a) distinguishing between similar faces, and b) classifications that don’t have definite boundaries, such as that of bushes or a crumpled garment. Typically, such identifications are not viewpoint-invariant.
