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.

The cognitive tests used to measure spatial visualization ability including mental rotation tasks like the Mental Rotations Test or mental cutting tasks like the Mental Cutting Test; and cognitive tests like the VZ-1 (Form Board), VZ-2 (Paper Folding), and VZ-3 (Surface Development) tests from the Kit of Factor-Reference cognitive tests produced by Educational Testing Service.
Since the pitch of music reproduction depends on rotation speed, these models have regular markings on the side of the rotating platter. The periodicity of these markings is calibrated in such a way that, under local mains frequency (50 Hz or 60 Hz), when the rotation has exactly the desired speed of 33 + 1/3 rpm, they appear to be static.
A form is an artist's way of using elements of art, principles of design, and media. Form, as an element of art, is three-dimensional and encloses space. Like a shape, a form has length and width, but it also has depth. Forms are either geometric or free-form, and can be symmetrical or asymmetrical.

A drawing of a butterfly with bilateral symmetry, with left and right sides as mirror images of each other.. In geometry, an object has symmetry if there is an operation or transformation (such as translation, scaling, rotation or reflection) that maps the figure/object onto itself (i.e., the object has an invariance under the transform). [1]
The first mathematical definition of gesture is given in the paper "Formulas, Diagrams, and Gestures in Music" (Journal of Mathematics and Music, Vol 1, Nr. 1 2007) by Guerino Mazzola (University of Minnesota) and Moreno Andreatta (IRCAM in Paris). A gesture is a configuration of curves in space and time.
In the philosophy of mind, neuroscience, and cognitive science, a mental image is an experience that, on most occasions, significantly resembles the experience of "perceiving" some object, event, or scene but occurs when the relevant object, event, or scene is not actually present to the senses.
