Verbal communication-the use of speech to get a direct point or idea across to a person
Non-verbal communication-the use of body language, or personal hygiene/dress to get subtle points across to others
In the picture, my roommate is wearing a sweater, indicating that he is cold. He also has his eyes focused on the book while types on his laptop to take notes, suggesting that he would like to efficiently complete his work. All of these are non-verbal communication. The verbal communication would be his asking me questions about things he doesn’t understand, or making statements. When he asks questions however, he keeps his head down and focused on the book still, meaning he wants the answer only and doesn’t want to diverge from his concentration on his studies, or get on another topic while discussing his work with me.
