An investigation of the saving-enhanced memory effect: The role of test order and list saving

Saving information onto external resources can improve memory for subsequent information-a phenomenon known as the saving-enhanced memory effect. This article reports two preregistered online experiments investigating (A) whether this effect holds when to-be-remembered information is presented before the saved information and (B) whether people choose the most advantageous strategy when given free choice of which information to save. Participants studied two lists of words; test order and whether and which list was saved (and re-presented again later) were manipulated. The saving-enhanced memory effect was only found when the first list (List A) was saved and tested after the second list (List B). When free to choose which list to save, participants preferred to save List A, but only when it was recalled after List B-that is, when it benefited memory. These findings suggest boundary conditions for the saving-enhanced memory effect and that people offload the most profitable information.

Automated summary

Saving information onto external resources can enhance memory recall, but only when the saved information is presented after the to-be-remembered information. Participants in two online experiments preferred to save the first list of words but only recalled it after the second list, suggesting that people choose to offload the most advantageous information.
