For letters b, c, and d, identify who the senders and the receivers would be. Also, explain what the non-verbal messages could be, and what the non-verbal feedback could be. Finally, explain if and why it’s mass or interpersonal communication—or both. Notice the sample answer for letter a. The woman is the sender; the customers and the barber are the receivers. The messages sent include that she just joined the Marines OR she is going through chemotherapy OR she’s in a rock band. It’s non-verbal because no one is talking, and it’s mass communication because there are more than two people in the barber shop.
