Once information has been integrated, summary information (e.g., average emotion or average size) can be extracted; this occurs during ensemble coding. Integration thus allows for fast and efficient generalizations about sets to be made. In contrast, the visual system sometimes segments input that does not go together. For example, the perception of objects can be exaggerated away from natural category boundaries (e.g., a perfect circle is a category boundary; it is neither "flat" nor "tall").
