The Principle of Closure
We tend to fill the gaps in stimulation and perceive the objects as whole rather than their
separate parts.

PERCEPTION OF SPACE, DEPTH and DISTANCE

The visual field or surface in which things exist, move or can be placed is called space.The

space in which we live is organised in three dimensions.We perceive not only the spatial
attributes (e.g., size, shape, direction) of various objects, but also the distance between the
objects found in this space.
In perceiving depth, we depend on two main sources of information, called cues.
 One is called binocular cues because they require both eyes.
 Another is called monocular cues, because they allow us to perceive depth with
just one eye.
MONOCULAR CUES OF DEPTH PERCEPTION are effective when the objects are

viewed with only one eye.
 These cues are often used by artists to induce depth in two dimensional
paintings.
 Hence, they are also known as pictorial cues.
 Some important monocular cues that help us in judging the distance and
depth in two dimensional surfaces are:
