The memory system characterised by both requiring little effort or attention to recall a memory and not declining much over long retention intervals is non-declarative memory. This type of memory includes skills, habits, and classical conditioning, and is also known as implicit memory. The other options, declarative memory, episodic memory, and semantic memory, require more effort and attention to recall and are more vulnerable to forgetting over time.
