Examples of ambiguous stimuli. (A) Hollow-face illusion: a concave mask looks like a convex face. (B) It is not possible to state which side of the Necker Cube is facing the observer: perspective-based reversals occur between two possible configurations of the cube.

The Necker Cube Pattern Control test is designed to measure one’s capacity to direct mental effort. It uses a wire-frame cube named after the Swiss crystallographer Louis Necker (1880s) who observed that cubic shapes repeatedly reverse their perceived orientation.

What causes the Necker cube illusion?

The Necker cube has shed light on the human visual system. The phenomenon has served as evidence of the human brain being a neural network with two distinct equally possible interchangeable stable states.

What is true of reversible figure-ground patterns?

What gestalt principle is the Necker cube?

The main principle in this theory is that the whole (gestalt) is more than the sum of the parts, i.e., the properties of the totality of a given image emerge when the human eye perceives the whole of the objects without paying attention to the elements of the parts constituting it [1] [2] [3].

Why is the Necker cube ambiguous?

Drawn in isometric perspective (parallel edges of the cube are drawn as parallel lines), there are no cues to determine whether one line crosses in front of or behind another. This creates an ambiguous situation where there are two possible orientations of the three dimensional cube.

What is the Ouchi illusion?

The Ouchi illusion, illustrated above, is an illusion named after its inventor, Japanese artist Hajime Ouchi. In this illusion, the central disk seems to float above the checkered background when moving the eyes around while viewing the figure. Scrolling the image horizontally or vertically give a much stronger effect.

What is the reversible figure-ground relationship?

Reversible figure/ground occurs when positive and negative elements attract our attention equally and alternately, coming forward, then receding, as our eye perceives one first as dominant and next as subordinate.
