This booklet, a discovery/work text, asks learners to take a careful look at the ways they participate in communication situations, at the form their participation in communication takes, and at the personal and societal consequences of communication. Laboratory activities focus on techniques of communication and on strategies for dealing with communication situations. Exercises and commentary are specifically addressed to the following questions concerning communication in social groups: What are some of the characteristics of communication in groups? How do groups use symbols in communication? How can communication be a tool for control? Why do we call communication a process? How does culture influence human communication? (KS)
