Question

Other than personal appearance, what are the other four nonverbal message channels that we use to communicate?

Answer 1

Body language is nonverbal communication that involves body movement and gestures. The catalogue of these movements, together with attempts at defining their meaning, is called kinesics. Each culture is believed to possess a separate “language” of kinesics. This branch of study is used in matters of negotiation and interrogation, where reading nonverbal cues is of great importance. According to the 2008 Encyclopedia Britannica, kinesics is a primarily American attempt at movement-classification, designed to Create a vocabulary of gestures, “both amusing and potentially practical.”

Answer 2

Body language is someway to communicate what we're thinking, along with facial expressions.
My favorite example of this is in "The Little Mermaid" when Ariel is about to lose her voice to Ursula the sea witch, and Ariel asks how she is going to make the prince fall in love with her without a voice.
"But without my voice, how can I-

You'll have your looks, your pretty face
And don't underestimate the importance of body language, ha!

The men up there don't like a lot of blabber
They think a girl who gossips is a bore
Yet on land it's much preferred for ladies not to say a word
And after all dear, what is idle babble for?
Come on, they're not all that impressed with conversation
True gentlemen avoid it when they can
But they dote and swoon and fawn
On a lady who's withdrawn
It's she who holds her tongue who gets a man

Come on you poor unfortunate soul
Go ahead
Make your choice..."

Hope this is of great help to you, and happy studying~!
