What are some ways that individuals use nonverbal communication to display prejudice or discrimination?

What will be an ideal response?

Nonverbal communication displays can highlight prejudice or discrimination when an individual refuses to look at a person when talking to them, chooses not to smile or stops conversation when a person enters the room, does not acknowledge another person's presence, will not touch another person's skin when giving them something, watches a person closely, or avoids a person when walking down a street.
