Question

What is the topic sentence? What evidence was provided? Who is the source for this evidence (author, organization):

People reveal a lot about themselves through their body movements. One thing you can do is watch how someone acts. When people lie, they might not show their emotions as much, or they might avoid eye contact. A study by DePaulo and colleagues (2003) found that when people lie, they tend to display fewer facial expressions, especially those related to emotions such as happiness and surprise, than truthful people. They also found that they tend to blink less frequently, avoid eye contact, and smile less often than truthful individuals. On the other hand, some people behave nervously by nature, so it is important not to make judgments solely on body language, or verbal clues. If you suspect you are being told a lie, be patient and wait for solid evidence before drawing conclusions. Nonetheless, body language, speech, and reactions can be red flags that alert you to pay attention and think a little more critically.
