The two types of implicit memory are which?

• A. Procedural memory and Implicit knowledge
• B. Declarative memory and Semantic memory
• C. Short-term memory and Long-term memory
• D. Sensory memory and Working memory

Answer: (A)

Implicit memory involves processes that influence behavior without conscious awareness. Procedural memory is the part that stores how to perform tasks and actions—like riding a bike, typing, or playing an instrument—so you can do them automatically without actively recalling steps. Implicit knowledge refers to knowledge you can’t easily articulate but that guides your judgments and actions, such as intuitions about grammar or social norms.

Other options mix explicit memory types or different memory categories (for example, declarative memory and semantic memory are consciously recalled, while short-term/long-term memory and sensory/working memory describe duration or processing stages rather than implicit memory). Thus, the best pairing is procedural memory together with implicit knowledge.
