Episodic recall of specifics and generalisation coexist in 25-month-old children.

It is clear that children generalise their knowledge of events from one instantiation to another. The means by which generalisation is accomplished are unclear. In three experiments, we used elicited imitation of multi-step sequences to test whether 25-month-olds' generalisation occurs as a function of forgetting of the features of the original event. Experiment 1 was an initial test of generalisation from one version of an event to another version involving perceptually different yet functionally analogous props. After a 1-week delay, children showed evidence of generalisation by enacting the event using the analogous props. Experiment 2 was a within-subject test of generalisation and memory for the original version of an event. After a 1-week delay, when paired with unrelated distractor props, analogous props served as effective retrieval cues; when paired with the original props, analogous props were treated as functionally equivalent to unrelated distractors. This within-subject reversal in the functional role of analogous props is compelling evidence that children's event representations include specific features and, at the same time, are generalisable. In Experiment 3, children showed evidence of generalisation immediately after exposure to an event, thereby making clear that generalisation occurs even in the face of robust memory for the specific features of the original event.
