Which type of memory involves knowledge concerning meanings and facts?

Semantic memory is the correct choice because it deals specifically with knowledge about facts, concepts, and meanings that are not directly tied to personal experiences. This type of memory includes information such as vocabulary, historical facts, mathematical principles, and general world knowledge. Semantic memory is essential for understanding language and can be thought of as a mental encyclopedia.

In contrast, implicit memory refers to memories that are formed without conscious awareness, often relating to skills and habits (like riding a bike). Episodic memories, on the other hand, are tied to specific personal experiences and events in one’s life, such as remembering a birthday party. Prospective memory focuses on remembering to perform actions in the future, like recalling to take medication at a specific time. Each of these types of memory serves different functions, but semantic memory is distinct for its emphasis on factual information and meanings.
