A stimulus that facitiates the recall of information memory?

A stimulus that facilitates the recall of information in memory is often referred to as a "retrieval cue." These cues can be contextual, such as environmental factors or emotional states, or they can be specific to the information itself, like keyWords or images associated with the memory. By providing a trigger, retrieval cues can enhance access to stored memories, making it easier to recall specific information when needed.
