Final answer:
Keri's anxiety when someone leans in closely is caused by cultural norms related to personal space, which varies across cultures. Cultural differences can influence how people interact, including the appropriate distance maintained during interactions and the interpretation of nonverbal cues.
Step-by-step explanation:
The cultural dimension causing Keri anxiety when someone leans in close to talk to her is likely related to personal space and comfort zones influenced by her cultural background. Cultures vary in their expectations and norms regarding the proper distance to maintain during face-to-face interactions. North Americans, for example, typically prefer to maintain a larger personal space, while some Middle Eastern cultures find it normal to stand closer during a conversation. Keri's discomfort suggests that her cultural norms value a greater amount of personal space.
Understanding and respecting this aspect of cultural diversity is critical in social interactions to avoid making others feel uncomfortable. It is also important to recognize nonverbal cues, which include maintaining a comfortable distance, as part of effective communication. Individuals should be aware of and sensitive to these cultural differences, especially when interacting in a professional environment or with people from diverse backgrounds.
