Final answer:
To recall your social security number without resorting to external aids is an example of utilizing explicit memory, which involves information we can consciously recall and is a part of our long-term memory.
Step-by-step explanation:
Explicit memory is divided into two subtypes: episodic memory, which relates to events and experiences in one's life, and semantic memory, which pertains to facts and knowledge. Recalling your social security number involves semantic memory, since it is a fact about oneself that has been memorized.
In contrast, implicit memory refers to memories we are not consciously aware of, such as procedural memory that involves skills and tasks. The act of recalling a social security number without cues is an example of effortful processing and represents a type of information that has been encoded into long-term memory through attention and effort.
Overall, remembering your social security number is an example of long-term, explicit memory as it's information you have consciously learned and committed to memory, which you can recall without the need for prompts or cues.
