Nonverbal communication (NVC) is usually unerstood as the process of communication through sending and receiving wordless messages. Such messages can be communicated through gesture; body language or posture; facial expression and eye contact; object communication such as clothing, hairstyles or even architecture; symbols and infographics. Speech may also contain nonverbal elements known as paralanguage, including voice quality, emotion and speaking style, as well as prosodic features such as rhythm, intonation and stress. Likewise, written texts have nonverbal elements such as handwriting style, spatial arrangement of words, or the use of emoticons.
