Usage in Context

  1. Cognitive ability or level: Describing someone's mental capacity to understand or process information, e.g., 认知水平 (cognitive level).
  2. Academic field: Used in terms like 认知心理 (cognitive psychology), focusing on how cognition works.

Notes

  • 认知 is a formal term, often found in academic or professional contexts rather than casual conversation.
