The appropriate response is Maintenance Rehearsal. It is a term for the part of redundancy in the maintenance of recollections. It includes rehashing data, again and again, keeping in mind the end goal to get the data prepared and put away in a memory. Upkeep practice is a sort of memory practice that is valuable in keeping up data in here and now memory or working memory.
