Toddlers of 14 and 18 months learned to produce target actions for six
activities, were allowed to forget their training, and were reminded
of the activities 8 or 10 weeks later, depending on their age. Reminde
rs were administered in a memory-reactivation paradigm in which toddle
rs were shown the target actions of three of the six activities but we
re not allowed to imitate the modelled actions. Toddlers were tested f
or their recall of all six activities 24 hours after the reactivation
treatment. Toddlers who were passively exposed to three activities dur
ing the reactivation session recalled more activities than controls wh
o either were not reminded or did not originally engage in the activit
ies. This study reveals that 14- and 18-month-olds encode components o
f an event associatively and that they are able to remember seemingly
forgotten components through passive re-exposure to other components o
f the event.
