Non-verbal communication is usually understood to mean the process of creating or representing meaning by sending and receiving wordless, usually visual messages. These can include facial expressions, gestures, body language and eye contact. But how, I hear you ask, can this possibly help the writer? We need to examine the concept in a little more detail.
Previous posts have discussed the art of showing, not telling. Non-verbal communication falls firmly into the ‘showing’ category. Our characters don’t have to say anything to convey how they are feeling. The postures they adopt, their facial expressions and unconscious actions or tics will all reflect their moods and tell the reader more about the characters’ thoughts and feelings than long paragraphs of description, speech tags and adverbs.
