Quick Summary

Gestures are movements of the body or limbs that convey ideas or feelings, serving as a form of nonverbal communication. They can include signs, signals, and mimes, and are often unique to specific cultures. While some gestures, like facial expressions, appear to be universally understood, many others vary significantly across different cultures and can lead to misinterpretation.1234

Gestures are a component of kinesics, a field that studies how body movements generate meaning, similar to how sounds form words in spoken language. Beyond conveying explicit messages, gestures can also add emphasis, express emotions, and regulate social interactions. In addition to gestures, nonverbal communication encompasses other signals such as facial expressions, tone of voice, and body posture.243
