The two main types of long-term memory are which?

• A. Declarative and Implicit
• B. Semantic and Episodic
• C. Procedural and Implicit
• D. Sensory and Short-term

Answer: (A)

Long-term memory is organized into two broad categories: declarative memory, which you can consciously recall, and nondeclarative (implicit) memory, which influences your behavior without conscious awareness. Declarative memory includes facts and personal events that you can describe, while nondeclarative memory covers skills, habits, priming, and conditioning. The pairing of declarative and implicit best reflects this fundamental split, since it captures both the conscious, reportable memories and the unconscious, performance-based memories. Semantic and episodic are subtypes of declarative memory, not the two broad divisions themselves, and procedural memory is a type of implicit memory. Sensory and short-term memories refer to different stages or stores, not long-term memory types.
