Final answer:
Explicit memory involves conscious recall of facts and events, while implicit memory affects our behaviors and skills without conscious thought. Implicit memory is typically less affected by aging than explicit memory.
Step-by-step explanation:
The difference between explicit memory and implicit memory lies in our awareness and intention in recalling these memories. Explicit memory, or declarative memory, includes information we consciously work to remember, like facts learned for a chemistry exam. This type of memory is further classified into episodic and semantic memory. On the other hand, implicit memory operates below the level of conscious thought, influencing our behaviors and skills, such as how to ride a bike, without our deliberate recall. Implicit memories include procedural, priming, and emotional conditioning memories.
Implicit memory is generally less affected by aging compared to explicit memory. This is because the retrieval of explicit memories often diminishes with age, whereas skills and procedures learned through implicit memory tend to remain more stable over time.
