types of effective communication techniques
The two major forms of verbal communication include written and oral communication. Written communication includes traditional pen and paper letters and documents, typed electronic documents, e-mails, text chats, SMS and anything else conveyed through written symbols such as language.
Physical nonverbal communication, or body language, includes facial expressions, eye contact, body posture, gestures such as a wave, pointed finger and the like, overall body movements, tone of voice, touch, and others. Facial expressions are the most common among all nonverbal communication.
