Revisiting the influence of offloading memory on free recall.
(2022) Kelly, M. O., & Risko, E. F.
Relying on external memory aids is a common memory strategy that has long allowed us to “remember” vast amounts of information more reliably than with our internal memory alone. However, recent work has provided evidence consistent with the idea that offloading memory demands encourages a reduced engagement in intentional or topdown memory strategies/efforts, leading to lower memory performance in general. Evidence for this view comes from results demonstrating a reduced primacy effect but intact recency and isolation effects when individuals could offload memory demands (but had to unexpectedly rely on their internal memory at test). In the present investigation, we attempt a replication of these critical results, given some inconsistencies in the findings between studies. In addition, we extend the examination of offloading’s impact on memory via examining individual differences in reliance on the external store (when available) and different strategies for the use of that store. Results of the replication are generally consistent with previous research. An individual differences analysis yielded results consistent with the notion that increased reliance on an external store can compromise internal/biological memory in the absence of that store. Finally, a verbal model of offloading memory demands within a framework of effort and study time allocation is presented. Together, the results both reinforce extant research and extend it in new directions.
