Which is a key element in determining the effectiveness of a message?

The effectiveness of a message is significantly influenced by non-verbal communication. This encompasses body language, facial expressions, gestures, and eye contact, all of which can convey emotions and urgency that might not be expressed through words alone. Non-verbal cues can reinforce or contradict the verbal message, shape perceptions, and enhance understanding. For instance, a confident posture and eye contact can instill trust and engagement, while a lack of eye contact might suggest disinterest or uncertainty. As such, mastering non-verbal communication is essential for conveying messages effectively and ensuring that the intended meaning is received by the audience.
