Final answer:
Personal space requirements do indeed change based on situational, relational, and cultural contexts, with examples existing across professional or casual situations and individualistic or collective cultures.
Step-by-step explanation:
The statement 'Personal space requirements change according to the situational, relational, and cultural contexts of the communication' is indeed true. Personal space, a crucial element of nonverbal communication, varies greatly across different situations, relationships, and cultures. For instance, in a professional situation, one might maintain more distance than in a friendly gathering. Similarly, cultures with a high regard for individualism like the US may value personal space more than collectivist cultures like China. Thus, the contexts can significantly influence one's perception of personal space.
