Final answer:
The term for truly photogenic memory is eidetic imagery, which is a form of long-term memory, while the clear recollection of an important event is known as a flashbulb memory. These are different from the engram, which is the physical trace of memory.
Step-by-step explanation:
The term for truly photogenic memory is eidetic imagery. This phenomenon is where an individual has the ability to vividly recall images from memory with high precision for a brief period after seeing them only once, without using a mnemonic device. In contrast, an exceptionally clear recollection of an important event, often with strong emotional ties, is known as a flashbulb memory. Additionally, the physical trace of memory in the brain is referred to as an engram. Both eidetic imagery and flashbulb memories fall under the category of long-term memory, but they represent different processes and capabilities within the human memory system.Regarding other types of memories, we have explicit memory, which is the memory of facts and events we can consciously recall and declare. Explicit memory can be further divided into episodic memory, which is autobiographical, and semantic memory, pertaining to facts and knowledge. Implicit memory, on the other hand, includes memories we do not consciously think about, such as procedural memories involved in tasks like riding a bike.In terms of forming new memories, the processes can be referred to as construction and reconstruction. This is because when we encode new memories, we are constructing them, and when we retrieve these memories, we may reconstruct them, potentially incorporating new information or altering them in some way.
