Eighteen-Month-Old Infants Generalize to Analog Props across a Two-Week Retention Interval in an Elicited Imitation Paradigm

We report a generalization experiment in which 72 18-month-old infants were tested in the elicited imitation paradigm. Two questions were addressed: (1) whether infants' were able to generalize to differently looking (shape and color changes) but functionally equivalent props and (2) whether narrative support at both encoding and retrieval would facilitate memory. The results revealed that the 18-month-old infants were indeed capable of generalizing to differently looking but functionally equivalent props across a retention interval of two weeks. However, contrary to expectations, narrative support did not facilitate memory or generalization.
