Is verbal language more effective than body language?

People respond more readily to what they see as opposed to what they hear.

The human brain processes visual cues automatically. When someone receives input like words and sounds, the logic center of the brain is activated. That means more cognitive resources are required when a person tries to just listen to what the other person is saying. When a person uses the proper body language, he is facilitating what he is saying with gestures, movements and expressions that can be readily deciphered by the other person.
