What Is Perception, and Why Is It
Important?
Perception
A process bywhich individuals organize and interpret their sensoryimpressions in
order to give meaning to their environment.
People’s behavior is based on their perception of what reality is, not on reality
itself.
Human mind assembles, organizes and categorizes information
Perception is our sensory experience of the world around us and involves both the
recognition of environmental stimuli and actions in responseto these stimuli.
Through the perceptual process, we gain information about properties and elements
of the environment that are critical to our survival. Perception not only creates our
experience of the world around us; it allows us to act within our environment.
Perception includes the five senses;
touch, sight, taste smell and taste. It also includes what is known as proprioception,
a set of senses involving the ability to detect changes in bodypositions and
movements. It also involves the cognitive processesrequired to process
information, suchas recognizing the face of a friend or detecting a familiar scent.
The perceptual process allows us to experience the world around us. Take a
moment to think of all the things you perceive on a daily basis. At any given
moment, you might see familiar objects in your environment, feel the touch of
objects and people against your skin, smell the aroma of a home-cooked meal and
hear the sound of music playing in your next doorneighbor's apartment. All of
these things help make up our conscious experience and allow us to interact with
the people and objects around us.

In this overview of perception and the perceptual process, we will learn more about
how we go from detecting stimuli in the environment to actually taking action
based on that information
Perceptual Illusion
A perception that appears True but is false
Stereo Image
Actual image is two slightly different two-dimensional images
Fused Image
Perceived image creates the illusion of depth
Method Anaglyph
Red filter admits only the red image Cyan or Blue filter blocks the red, allowing
the other colors
Anaglyph
Images are viewed from different
perspectives
but appear in the center
of the retina in both eyes.

Double images
In this image there are two faces, are man playing a
saxophone and on this face has a one more face. In this
image man and women both are available

The figure has eight white circles, and in each
circle there are three black lines. There are no
lines between the circles; there is no cube.
Most people, however, see a cube, either
floating in front of a black sheet with white circles, or behind a black
sheet with eight holes.
Probably a cube. Does it seem to be floating in front of a black
background with white dots on it? Or, rather, to be lying behind a black
sheet with holes punched into it? As to the cube itself, is the surface that
seems closest to you angled up and to the left or angled down and to the
right? Why see a cube at all? The image, of course, is actually flat on the
page. You might swear that you can see the lines of the cube crossing
the black region, but they are not present in the image. There are only
eight carefully positioned white dots, each containing a carefully
positioned set of three line segments.
