Final answer:
When trying to remember what you did last Friday night, you are using episodic memory, which is a type of declarative memory involving personal experiences.
Step-by-step explanation:
If you are trying to remember what you did last Friday night, the type of long-term memory you would be using is episodic memory. This is a type of declarative memory that contains information about events we have personally experienced or participated in, often referred to as autobiographical memories. When you recall last Friday night, you’re retrieving an episodic memory which typically involves a narrative or story-like recollection of the sequence of events, the place it happened, and the time it occurred. Recalling last Friday night could also involve sensory details and emotions that you experienced during the event.
It is important to note that there are other types of long-term memories as well. Procedural memory is responsible for knowing how to do things, such as riding a bicycle or playing an instrument, representing our motor skills. Semantic memory, on the other hand, is about facts and knowledge that we can state, such as knowing the capital of a country or the definition of a word. These are both different from episodic memory, which is deeply personal and related to one’s own experiences.
