Final answer:
In computer-mediated communication (CMC), self-presentation is actually more important in the initial stages of a relationship.
Step-by-step explanation:
The answer choice that is NOT true when comparing face-to-face communication to computer-mediated communication (CMC) is option D: In the initial stages of a relationship self-presentation is less important in CMC messages.
In fact, in CMC, self-presentation tends to be more important in the initial stages of a relationship because individuals have more control over how they present themselves online. They can carefully craft their online persona and choose what information to share with others.
On the other hand, in face-to-face communication, non-verbal cues such as body language, tone of voice, and facial expressions play a prominent role and can influence the perception of self-presentation in the early stages of a relationship.
