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 a dog is a type of animal are aspects of semantic memory. Unlike episodic memory, which relates to personal experiences and specific events, semantic memory is more about the information we acquire over time. It allows us to understand language, recognize objects, and engage in reasoning. This type of memory is essential for learning and communication.
