Final answer:
Remembering the present you bought for your aunt involves explicit memory, specifically episodic memory, as it is a conscious recollection of a personal event.
Step-by-step explanation:
To determine if you would need implicit or explicit memory for remembering what present you bought for your aunt requires understanding the difference between the two memory types. Explicit memory is the type of memory you consciously try to remember, recall, and report. It is divided into episodic memory, which is personal experiences, and semantic memory, which refers to facts and general knowledge. Remembering the present you bought for your aunt would fall under explicit memory, likely as an episodic memory because it is an event that you would consciously recall.
