Ekman’s research on deception

Ekman’s research on deception focuses on identifying physiological and behavioral cues that indicate someone is lying. He studied facial expressions and microexpressions—brief, involuntary facial changes—that reveal genuine emotions even when a person is trying to conceal them. Ekman found that certain facial signals, body language, and sweat responses can help detect deception. His work emphasizes that lying often involves inconsistent expressions or subtle signs, and understanding these cues can improve lie detection. Overall, his research enhances our ability to interpret underlying emotions through nonverbal communication.
