principles of perception

Most of the principles of perception is an organizing principle based on Gestalt theory. Gestalt theory believe that perception is not the sum of the parts are sensed someone, but more than that is the whole. Gestalt theory outlines several principles that can explain how people organize sensations into a form of perception.

The following figure shows that human perception is not the sum of its elements [inverted triangle plus a square cut blue], but one can see a white triangle in the middle though without the lines that form the triangle.

The perception of the main principles is the principle of figure and ground. This principle describes that man, intentionally or not, choose from a series of stimulus, which became the main focus or form [= figure] and which is a background [= ground].

Example pictures of girls and grandmothers, shows that one can render a form as a girl figure, and the details of the other as a ground, or vice versa.

Several other visual examples can be seen below.

 

In everyday life, intentionally or not, we will pay more attention to certain stimuli than others. That is, we make the information into a figure, and other information to ground. One of the psychological phenomenon that illustrates the principle is, people tend to hear what he wanted to hear, and see what he saw.
