This paper identifies the origins of the concept of feedback and its entry into the interpersonal communication literature as a social science variable. It touches on why feedback might be important in interpersonal relations, what it consists of, some of the relevant research, and some possible dangers or misuses. It speaks to how the process of giving and providing feedback increases confidence and reduces uncertainty in interpersonal communication. It provides some suggestions for giving feedback and receiving it. Attached is an appendix of some of the ideas of Norbert Weiner for class distribution and discussion, a list of common defense mechanisms, and three instruments for making applications of the feedback concepts. One is a warm-up on asking for feedback, another is a list of suggestions for providing it, and a third is a PIB (personal improvement blank) for students to reflect on and fill out and return after the session is over. This is seen as a possible one-session class on feedback in interpersonal communication for lower division university undergraduates or community college students. Contains 22 references. (Author/RS)
