Law of Continuity

Perception and Psychophysics Effects

The law of continuity is a Gestalt psychology principle holding that visual elements arranged along a continuous line or smooth curve are perceptually grouped together and integrated into a single object, even where that object is partly interrupted or overlapped by something else. The effect means that when one shape passes behind another, a viewer perceives the partly hidden shape as a single uninterrupted whole continuing behind the obstruction, rather than as two separate fragments coincidentally aligned on either side of it.

Facts
Core Claim
Wertheimer 1923 account holds that where contours intersect, the mind resolves the arrangement into the smoothest continuous path through the intersection rather than an arbitrary one, an effect he called the Factor of the Good Curve. 1
