Final answer:
In Jeopardy!, contestants use semantic memory to recall language-based knowledge and facts, which is a type of declarative memory.
Step-by-step explanation:
In the game show Jeopardy! contestants are tested on general information. The type of memory used to answer these kinds of questions is semantic memory. Semantic memory is a type of declarative memory that includes knowledge about words, concepts, and language-based knowledge and facts. When contestants recall facts and concepts that don't relate to specific personal experiences or events, they are utilizing their semantic memory.
This is in contrast to episodic memory, which contains information about events we have personally experienced, also known as autobiographical memory. Other forms of memory, such as procedural memory (memory for making skilled actions) and working memory (short-term processing of information), are not typically utilized in the context of a trivia game show like Jeopardy!
