Abstract

By saving information on external memory stores, we can offload temporarily irrelevant memories, we believe to be important in the future. The external saving of encoded items enhances subsequent memory performance for new information (Storm and Stone in Psychol Sci 26(2):182–188, 2015). Across three experiments, we replicated and specified this saving-enhanced memory effect. In Experiment 1, we replicated the benefits of saving and showed that they are robust against changes in instructions. In Experiment 2, we extended the saving-enhanced memory effect to motor material and more important, found evidence for better encoding after saving. In Experiment 3, a cost effect for saved verbal material was present, indicating that externally saving information can reduce the accessibility for this information afterwards. These findings suggest that at least two factors contribute to benefits of saving, better encoding and reduced interference at recall. Hereby, similarities of saving-enhanced memory to effects of the list-method directed forgetting phenomenon and useful implications for our daily information management are provided.

Parallel to Tempel & Frings (2016), we ran two versions of the experiment that differed in minor procedural aspects (different response keys for L2 and a short break between study of L1 and study of L2). We ran both versions in order to reconstruct the study of Tempel & Frings as closely as possible but did not expect to find any variation of effects across these versions. Fittingly, including experimental version as a factor did not change any significance of results, nor did the main effect of experimental version or the interaction of experimental version x trial condition reach significance, Fs < 1.
