Semantic memory is a type of long-term memory that involves the storage and recall of factual information and concepts. It includes knowledge about the world, such as the meanings of words, historical facts, and general information about objects and events. For example, knowing that Paris is the capital of France or that water is a liquid at room temperature are aspects of semantic memory. Unlike episodic memory, which relates to personal experiences and specific events, semantic memory is more about understanding and recognizing information that is not tied to a particular time or place. This type of memory allows individuals to communicate effectively and navigate their environment by using learned knowledge.
