Communication is far more than speech and writing. Most of us are unaware that we are communicating in many different ways even when we are not speaking. Growing up in a society, we informally learn how to use gestures, glances, slight changes in tone of voice, and other communication devices to alter or emphasize what we say and do. We learn these highly culture bound techniques over years largely by observing others and imitating them. Input to the analysis of various features of hidden aspects of communication will be supplied by multimedia materials.
