Studies have shown that simply creating the same internal state that you had at the time of encoding is sufficient to serve as a retrieval cue.[17] Therefore putting yourself in the same mindset that you were in at the time of encoding will help recall in the same way that being in the same situation helps recall. This effect called context reinstatement was demonstrated by Fisher and Craik 1977 when they matched retrieval cues with the way information was memorized.[18]
