Final answer:
Personal space, eye contact, and facial expressions are key elements of nonverbal communication related to proximity.
Step-by-step explanation:
Personal Space: An individual's cultural background can influence their comfort zone when it comes to personal space. Many people are most comfortable maintaining an arm's length of space between each other when talking face to face. In others cultures, it's acceptable to stand closer. Pay attention to cues from co-workers and be aware that standing too close can make the other person uncomfortable. At the same time, standing too far away can give the impression that you aren't interested in communicating.
Eye Contact: When greeting or conducting a conversation, direct eye contact indicates that you're engaged and alert. Avoiding eye contact may convey that a person is lacking in self-confidence or is unfriendly. Staring or maintaining constant eye contact for long periods, however, is to be avoided.
Facial Expressions: Facial expressions play a crucial role in nonverbal communication. They can convey a wide range of emotions, such as happiness, surprise, anger, and sadness. By observing someone's facial expressions, you can often tell how they are feeling or reacting to a situation.
