In these two videos, Carl Isaacson and his class discuss the concept of nonverbal communication. During the classes, Isaacson discusses theories of nonverbal communication and how we can use our understanding of this human communication construct in our daily lives. Using common examples, he addresses elements of nonverbal communication such as eye contact, gesture, personal space, haptics, and clothing/appearance, to name just a few. Non-verbal communication is a critical element of interpersonal communication. Because our gesture and other non-verbal communication behaviors are often subconscious responses, non-verbal communication reinforces or may conflict with consciously constructed verbal messages.
