Answer:
The 3 primary memory levels are encoding, storing, as well as retrieval.
1. Encoding threshold: This threshold will assist Roger to receive, procedure and combine information.
Encoding would allow knowledge (identities) to enter your senses during your wedding reception in the context of physical and chemical stimuli.
2. Storage Level: This level would allow Roger to build a permanent archive of encrypted data (names). It will allow him to keep up with details across time.
3. Retrieval level: This proportion should allow Roger to recall information stored (names) in answer to any prompt for use in a system or method.
