Because of this, it’s normal for people to notice 3 adjustments in episodic memory as they age:

  • Because finding out decreases, info might require to be duplicated a number of times in order to obtain it into the hippocampus so it can be born in mind.
  • Because the search procedure slows down, it might take more time or a tip or a sign to retrieve a memory.
