This chapter introduces you to the role of perception and the role of the self in communication. The chapter opens by explaining what perception is; then it describes why differences in perception occur and what occurs during perception. Next, the chapter moves to our perceptions of others, including errors we occasionally make in those perceptions. A discussion of self-awareness, self-concept (which includes self-image and self-esteem), and self-presentation completes the chapter. After you read this chapter you will have a better understanding of the communicative importance of how you see yourself and how you see others.
