This document discusses 12 different signal systems used for communication: verbal, written, numeric, pictorial, audio, artifactual, kinesic, optical, tactile, spatial, temporal, and olfactory. Each system is briefly defined. The document also outlines 3 principles of signal systems: they are rarely used alone, using multiple systems can lead to contradiction, and less consciously used systems are believed over more conscious ones.
