Final answer:
Analyzing body language and ensuring a person is comfortable by observing their non-verbal cues is a part of Personal Space Awareness, which is vital for effective interpersonal communication.
Step-by-step explanation:
​Understanding someone's non-verbal communication or body language is an important aspect of interpersonal skills. Checking a person's body language to ensure they are not tense or hurried is primarily associated with Personal Space Awareness. This includes being cognizant of their eye contact, body positioning, personal space preferences, and other kinesics like gestures and facial expressions.
Maintaining an appropriate amount of personal space and being mindful of non-verbal cues like avoiding crossed arms or fidgeting can help build a positive engagement. It's also important to be attentive to paralanguage elements such as tone and language, which supplement body language cues in communication. Moreover, cultural norms play a crucial role in shaping our understanding of and response to non-verbal signals, directly affecting interpersonal dynamics.
