The Process of Getting Information
Observing any such sign and getting information from it seems like a simple matter and can take place in an instant, and yet the process of getting information consists of three steps:
1. Perception
The sign and the observer share a context of place and time in which the sign attracts the observer’s attention. Robinson Crusoe, to use our first example, walked where the footprint was, looked in the right direction, when there was sufficient light for visibility, and before the print had been obliterated by rain, wind, tide, or the movement of other creatures.
2. Identification
Every perception is a unique experience. To say that we ‘recognize’ a phenomenon means that we match it with previous experiences stored in our memory. Almost certainly, if you observe a sign and derive some meaning from it, you must have seen a similar sign before. We identify any new thing either as a phenomenon previously observed or, more often, as something that is ‘identical’ with phenomena we already know, a new token of a familiar type. The human mind cannot deal with an infinite number of separate things; we classify an entity as a new instance of the class of footprints or bushes or sirens or churches. And to identify what something is requires us to recognize what it is not, to discriminate between signs.
3 Interpretation
Meanings are often personal. The meaning of any sign depends on the space-time context in which we observe it. Crusoe’s reaction to the footprint was due to the circumstances of his life, the fact that until this moment it had been impossible for him to see any human footprint other than his own. This is clearly an unusual case, but all the time we interpret differently in different contexts. Conventional signs can have different meanings in different contexts or different circumstances. The whistle of a policeman directing traffic, the whistle of a hotel doorman summoning a taxi, and the whistle of the referee in a soccer game may all sound exactly the same; their different meanings are due to the difference of context in which the signal occurs. They have different intentions and are interpreted differently.
