Semantic memory is a long-term memory type that focuses on knowledge and concepts that does not concern specific personal experiences or events. Unlike episodic memory which captures personal events, semantic memory is designed to help the individual remember that the capital city of France is Paris, understand how to articulate simple words and sentences, and know how to use various common tools and objects.
Communication, reasoning, and learning all depend on this system which is the foundation of all human knowledge. For instance, knowing that a dog is an animal or that there are a total of four in two and two are examples of semantic memory.
The medial temporal lobes focusing on the anterior temporal lobe are highlighted in the research for supporting semantic memory. Semantic dementia and other conditions that damage these areas disrupt the understanding of words and concepts. This is an example of how semantic memory aids in the ability to think, interpret, and navigate the world.
