 Welcome to Unit 1 of Communications 001. In this video, we're going to quickly highlight a few things you need to keep in mind while working through the unit. This unit is designed to introduce you to the basic components of communication and to introduce you to many theories that will help you understand the phenomenon of communication. Key concepts to watch for in this first unit include the models of communication, the process of perception, and the complementary relationship between listening, verbal, and non-verbal communication. Best of luck on Unit 1 and we'll see you again before Unit 2.
