INTRODUCTION TO PSYCHOLOGY
Perception
![Page 2: Perception2](https://reader033.fdocuments.net/reader033/viewer/2022060109/55550bc5b4c905c35e8b5202/html5/thumbnails/2.jpg)
Perception
“Perception refers to the interpretation of what we take in through our senses. In terms of optical illusions this means our eyes.”
Simply put, our brains are tricked into seeing something which may or may not be real.

Factors that Influence
Perception The Object of Perception:
some things in our environment tend to attract attention
Backgrounds and Surroundingsour surroundings at the moment of perception will affect our perceptions
The Perceiverwe each bring unique experiences and personal points of view to each situation

In order to make sense of our world our brains try to see patterns or shapes that are recognizable. This principle is called
“grouping”.

After a Necker cube is perceived from one perspective, it naturally tends to change to the other in about 3 seconds.

• When you look at the top figure, your visual system will organize the elements into a box. The box will reverse, as in the Necker Cube illusion. The elements in the bottom figure have terminations and do not readily group into a box figure that shows reversals

You will see it flip into a second staircase
• M.C. Escher used complex variations on this illusion to achieve some wonderful effects like showing representations of people walking in opposite directions, both descending. He also joined staircases into an appearance of infinite ascent/descent.

The shades of red are identical
The difference in the appearance is related to the influence of the
backgrounds. http://psycharts.com/opt_illus.html
Compare the shades of red…

When you look at the figure you will see either a vase or two faces. If you continue to look, the figure will appear to shift to the alternative organization

Perspective is evoked in this image by the pattern, and the lines on the wall which converge on to a common point in the distance.
