Recognition-by-components Theory - Geons

Geons

The recognition-by-components theory suggests that there are less than 36 geons which are combined to create the objects we see in day to day life. For example, when looking at a mug we break it down into two components – “cylinder” and “handle”. This too works for more complex objects, which in turn are made up of a larger amount of geons. Perceived geons are then compared with objects in our stored memory to identify what it is we are looking at. The theory proposes that when we view objects we look for two important components.

• Edges – This enables us to maintain the same perception of the object regardless of viewing orientation.
• Concavities – The area where two edges meet. These enable us to observe the separation between two or more geons.
