Which of the following is NOT a part of non-verbal communication?

Typography is indeed not a part of non-verbal communication. Non-verbal communication encompasses the ways in which people convey messages or express feelings without using words. This includes body language, posture, facial expressions, and tone of voice.

Posture affects how one is perceived and conveys confidence or submission. Facial expressions are crucial as they can communicate a wide range of emotions instantly without spoken language. Tone of voice also plays an essential role in conveying sentiments behind verbal communication, such as enthusiasm or sarcasm.

Typography, on the other hand, refers to the style and appearance of printed or written text. It is primarily associated with written communication rather than the non-verbal cues that occur in face-to-face interactions. Thus, typography does not belong to the realm of non-verbal communication, making it the correct choice for this question.
