Perception Principles Perception is relative rather than absolute.
Perception is very selective.
Perception is organized. Perception is influenced by set. Attention is drawn and held by complexity, providing the complexity does not exceed the perceivers cognitive capacities. People direct their attention where they will, i.e., where their interests, experiences, and needs suggest. Concept Learning Principles Concepts enable us to simplify, categorize, and thus better cope with the diversity surrounding us.
