Perception

Perception is a very important concept in psychology, if not said to be the most important. Through the human  Perception looked at the world. Does the world look "colored" bright, pale, or black, are all human perception is concerned. The perception should be distinguished by sensation [sensation]. The latter is a physiological function, and more depending on the maturity and the functioning of the sensory organs. Sensations include visual, audio functions, smell and taste, as well as perabaan, balance and motion control. All of this is what is often called the senses.

So we can say that the sensation is a human process in sensory information in receiving [the physical energy of the environment] through remote sensing and translate that information into signals "neural" means. For example, when a person sees (using the visual senses, i.e. eye) an object is red, then there is a wave of light from the object was arrested by the organs of the eye, then processed and transformed into signals in the brain, which was later interpreted as "red".

In contrast to sensation, perception is an active process of human beings in sorting, grouping, and give meaning to the information it receives. Red colored objects will give a sensation of the color red, but certain people will feel excited when seeing the color red, for example.

A classic example of this perception function looks in the picture below. Consider well, the picture who you see?

   

Now, look at the next picture:

 

 

In the example of the first picture, maybe you'll see a picture of a girl who was looking towards the right. In the second figure, maybe someone will still see a girl like in the first picture, but some others will see a grandmother. Grandma or a girl that you see? Do you also get to see the opposite [of the girl's grandmother, and from my grandmother to my girl]? If you can see both at the same time?

This classic example illustrates the power of perception. This image is a simple stimulus concerns only one visual, and sensation are enough to produce a different perception. Imagine in everyday life, there are so many perceptual experiences that are very likely give rise to a different perception.
