Problem: In an experiment, you are asked to remember events from your personal past. Included in these, you remember your weekly trip to return your books to the University Library. Four months later, you return to the lab and are asked about these memories again. In helping you to recall this event, you are provided with the cue 'University' by the experimenter and not the cue 'books' that you generated at the time of the initial recall. What empirical observation will the researchers find?
