Perception and Recognition

The first element involved in the human information processing that facilitates knowledge construction is perception of the event, and then use of memory to give this perception a recognition.


As shown in Figure 1, perception of displays occurs through stimuli generated by various sensory inputs - e.g. vision, audition, chemical senses - i.e. smell and taste. This system recognizes the information, assembles it, and makes comparisons with previously stored material (knowledge). Knowledge is used, reused and hence gets constructed.

Perception is a selective process and certain amounts of information from the outside are selected because not all of the information coming in can be assimilated. Perception is affected by factors such as attitudes, values, motives, stress and a person’s background.
