Which non-verbal behavior can hinder the communication process?

Nervousness is a non-verbal behavior that can significantly hinder the communication process. When an individual displays signs of nervousness, such as fidgeting, avoiding eye contact, or exhibiting an anxious posture, it can create barriers to effective communication. This behavior may lead the receiving party to feel uncertain, distracted, or even uncomfortable, thereby impairing their ability to receive and interpret the intended message accurately.

In contrast, gestures, posture, and eye contact, when used appropriately, can complement verbal communication and enhance clarity. Gestures can emphasize points and convey enthusiasm, posture can indicate confidence and openness, and eye contact can foster connection and demonstrate engagement. However, nervousness tends to detract from these positives, making it the behavior that most directly obstructs the flow of communication.
