He believes that each culture has its own speech code which shapes the behavior and cognitive processes of those within the society. For example, Philipsen studied the culture of Teamsterville and Nacirema and found two distinct communication patterns. Nacirema speech codes are one's of openness and supportiveness.
People are egalitarian and encourage the voicing of anyone's opinions no matter how old or young.
On the other hand, Teamsterville speech codes do not accept or tolerate children voicing their opinions to adults. The rules and meanigs of communicating stem from the categories people are put in, whey they are put there, and how we discover them in the categories. Both the speaker and listener apply their own meanings to words. They are not acting within the process of communication, but creating their own rules, meanings, and premises of communicating. When paying attention to communication patterns one can define and identify the terms and rules of a speech code.
