Episodic memory involves conscious recall of personally experienced events, including details like what, where, when, and associated emotions. Semantic memory consists of knowledge about words, concepts, and facts reported as factual information. For example, remembering your last birthday is episodic memory, while knowing Paris is the capital of France is semantic memory.

Episodic memory is autobiographical, meaning it is tied to personal experiences and specific contexts, capturing events at particular places and times. Semantic memory is independent of personal identity and context. Recalling the emotions felt during your first drive is episodic; knowing that water boils at 100 degrees Celsius is semantic.

Semantic memory comprises language-based knowledge including expertise, general knowledge learned in school, word meanings, famous individuals, and important places. It encompasses factual information accessed without recalling when or where it was learned. Examples include recognizing the Eiffel Tower as a famous landmark or knowing that Lima is the capital of Peru.

Explicit memories are also known as declarative memories. They involve conscious recollection of events and facts that can be deliberately recalled and reported. Studying for a chemistry exam involves material that becomes part of explicit memory, which can be consciously remembered and articulated.

Episodic memories are remembered as stories or episodes, capturing specific events at particular places and times with associated details and emotions. For example, remembering your last birthday includes details of the event and the feelings experienced. These memories form an autobiographical record of personally lived experiences.

Explicit memories require conscious recollection, meaning they are deliberately recalled and reported. Unlike implicit memories, explicit memories involve awareness and intentional retrieval of information. Both episodic and semantic explicit memories depend on this conscious, deliberate recall process for successful remembering.

Semantic memory consists of general knowledge and facts that can be accessed without remembering the specific context or personal circumstances of learning them. Knowing that the Eiffel Tower is located in Paris does not require recalling when or where you learned this fact. This independence from personal context distinguishes semantic memory from episodic memory.
