Which memory system is classified as nondeclarative memory?

• A. Declarative memory
• B. Working memory
• C. Nondeclarative memory
• D. Episodic memory

Answer: (C)

Nondeclarative memory refers to the implicit memory systems that operate without conscious awareness. It includes procedural memory for skills and habits, priming, and conditioning—things you can do or influence without being able to verbalize how you learned them. These memories are not readily verbalizable, which is why they are categorized as nondeclarative. In contrast, declarative memory is explicit and split into episodic (personal experiences) and semantic (facts) memory, both of which you can consciously recall. Working memory is a separate short‑term system for holding and manipulating information. Since the question asks which memory system falls under nondeclarative memory, the answer is the nondeclarative memory category itself—the implicit systems that guide behavior without conscious recollection.
