What is 'semantic memory'?

Semantic memory refers to a type of explicit memory that encompasses the storage and recall of factual information and knowledge about the world. This includes concepts, ideas, general knowledge, language, and the meanings of words. Unlike episodic memory, which is centered around personal experiences and specific events, semantic memory is not tied to a particular time or place and does not require personal context for retrieval.

This type of memory allows individuals to understand and engage with the world around them, facilitating learning and communication. For instance, knowing that Paris is the capital of France or that a tiger is a large wild cat are examples of factual knowledge that fall within the realm of semantic memory. The clarity of this definition aligns with the concept of explicit memory, which involves conscious recall, distinguishing it clearly from implicit memory and emotional experiences that pertain to other types of memory.
