Briefly explain the Hologram theory.
Memories can be reconstructed like three-dimensional images from any fragment of the memory. Just one fragment can evoke the entire memory, though smaller fragments lead to fuzzier memories
EX. Scan the room and notice a certificate on the wall which is similar to a memory of the past but you do not have access to recollection only familiarity
Briefly explain the divided attention theory.
Brain subconsciously encodes an environment while we focus our attention on something and When attention returns, we feel as if we have been here before
