Perception is the process of how we interpret information that we gain from our senses. Perception is individualized and therefore different people see and think different things about the same situation. We perceive things by categorizing and grouping them in several ways including similarity, proximity, continuity, and closure.
If something is similar or looks like something else, it goes in the first group. Proximity groups things depending on how close they are spatially to one and other. The third way of grouping things is based in the idea of patterns. If we can see a pattern, we group things by continuity. Lastly, we generally let our minds fill in missing information such as the side of a circle, so that we can put them in the “circle” category. Grouping things around us helps us understand and interpret our world.
I think this site is interesting because it provides pictures and examples of different perceptions: http://www.worldtrans.org/TP/TP1/TP1-9.HTML
