Abstract
An experimental paradigm has shown that it is possible to activate spontaneous memories in children by having them re-visit the setting in which they were introduced to a memorable event. Nevertheless, the most important cues for spontaneous recall remain undetermined. In response, we investigated the importance of the experimenter by introducing 35-month-olds (n = 62) and 46-month-olds (n = 62) to the same or a new person after one week. We expected that altering the experimenter would result in fewer recollections through reducing the overlap of cues between encoding and testing. In contrast, the manipulation affected the two age groups differently: no effect of condition was seen in the 35-month-olds, whereas the 46-month-olds performed better, when the experimenter had changed, suggesting a sensitivity to change and an ability to update their knowledge of the event. We replicated previous findings demonstrating that both age groups exhibited spontaneous recollections.

Notes
In Krøjgaard et al. (2017), seven dimensions were used, but in the present study we decided to omit the ‘object’ dimension because we encountered problems in identifying unambiguous criteria by which the object dimension could be coded during coder training.
Given that we failed to obtain CDI data from one participant, these analyses were based on n = 123.
