Which of the following best represents an example of declarative memory?

Declarative memory refers to the type of long-term memory that involves the conscious recollection of facts and events. It is divided into two subcategories: episodic memory, which is the memory of personal experiences and specific events, and semantic memory, which encompasses general knowledge and facts about the world. The retention and recall of facts, as indicated in the correct answer, is a clear illustration of declarative memory, as it involves the ability to consciously access and articulate factual information.

Other concepts mentioned, such as procedural skills and priming effects, fall under different categories of memory. Procedural skills pertain to implicit memory, which is responsible for the unconscious learning of tasks and motor skills, like riding a bicycle. Priming involves the implicit memory effect where exposure to a stimulus influences response to a subsequent stimulus, which also does not involve the conscious retrieval typical of declarative memory. Nonassociative learning relates to changes in behavior after repeated exposure to a single stimulus, such as habituation or sensitization. These forms of learning represent different memory processes distinct from declarative memory's focus on fact-based recall and recognition.
