Final answer:
The typical non-verbal communications used by people who are lying include inconsistent facial expressions and body movements.
Step-by-step explanation:
When people are lying, they often display inconsistent facial expressions and body movements. This can include facial expressions that do not match the emotions being expressed, sudden changes in body posture, or fidgeting. These non-verbal cues can indicate that the person is being deceptive.
For example, someone who is lying may smile while talking about a sad event or avoid making eye contact. They may also use hand gestures more frequently or appear more relaxed in their facial expressions as a way to distract from their deception. It's important to note that these behaviors may not always indicate lying, as everyone's non-verbal communication styles can vary.
