11.11 - CATEGORISATION:
The Human mind in the process of understanding naturally categorises objects that it has seen. This categorisation helps the mind to understand easily as under:

a. It makes complexity manageable
b. It speeds up recognition
c. It makes events predictable
d. It supports systematisation
e. It bonds social behaviour
f. It tailors the world to our purposes
g. It makes the world seem more meaningful.

11.12 - INFLUENCE OF LANGUAGE IN PERCEPTION:
The study has demonstrated that when questions are asked about car accidents, the answers differed drastically when the words of the question were changed. The word "smash" was also involved in answers about the car speed showing that the speed was perceived more than when the word "going" was used.

11.13 - SELECTIVITY AND ADDITION:
Redundancy plays an important role in noticing the visual data. We don't always need much data in order to recognise something. Often one can manage with minimal visual data. The 'blocky' pictures of famous people can be recognised easily. Our schemata allows us to' fill the gaps' because we know what should be there. This also involves 'addition'. Selectivity involves organisation, fore grounding, back grounding, rearranging etc. Sharpening and levelling is also a part of the perception process. Sharpening and levelling is more when the understanding is more coherent and well rounded. Selective perception is based on what seemed to 'stand out'. This standing out is related to our purposes, interests, expectations, vast experiences, current demands of the situation, etc.
