Perception
-
powers of the mind that are thought to transcend the conventional laws of physics and our ordinary understanding of natural science. Psi powers are also called sometimes“wild talents.”
-
There are three kinds of extrasensory perception: (1) precognition, (2) telepathy, and (3) clairvoyance

An illusion is a false perception, a perception that does not fit an objective description of a stimulus situation :
Depth perception is made possible by various cues, signals or stimuli that provide an observer with information
Binocular vision is vision with two eyes. The principal cue for depth perception associated with binocular vision is retinal disparity
Monocular vision is vision with one eye. If a person is deprived of binocular vision, then he or she can still perceive depth with the assistance of monocular cues
A first monocular cue is linear perspective, the tendency of parallel lines to seem to converge as they approach the horizon
-
A third monocular cue is shadows. Shadows are differences in illumination gradients. These tend to help us see rounded surfaces as convex or concave
-
A fourth monocular cue is texture gradient. A texture gradient is perceived when we can see less detail in far away objects than those that are closer to us.
A second monocular cue is interposition, a cue created when one object blocks some portion of another object.

Kurt Koffka (1886–1941), one of the founders of Gestalt psychology, said that
the great question of perception is: “Why do things look the way they do?”
closure is the tendency to fill in gaps in information and make a perceptual object into a complete whole
-
Learning also plays a role in perception because we are conscious beings who attach labels to perceptual objects.
-
-
Cognitive learning, learning in which consciousness plays an important role, is an important aspect of the perceptual process.
