>According to A. Barbour, author of Louder Than Words: Nonverbal Communication, the total impact of a message breaks down like this:

• 7 percent verbal (words)
• 38 percent vocal (volume, pitch, rhythm, etc)
• 55 percent body movements (mostly facial expressions)

Effective communication is the combined harmony of verbal and nonverbal actions. Nonverbal communication consists of body movement, facial expressions and eye movement.
Body Movement indicates attitude, conveys feelings serves as illustrators and regulators. Illustrators are nonverbal movements that accompany and illustrate verbal communication.
