Abstract

The technological advancement that is rapidly taking place in today’s society allows increased opportunity for “cognitive offloading” by storing information in external devices rather than relying on internal memory. This opens the way to fundamental questions regarding the interplay between internal and external memory and the potential benefits and costs of placing information in the external environment. This article reports the results of three pre-registered online experiments investigating the consequences of prior cognitive offloading on A) subsequent unaided ability, and B) strategic decisions whether to engage in future cognitive offloading. We administered a web-based task requiring participants to remember delayed intentions for a brief period and manipulated the possibility of setting reminders to create an external cue. Earlier cognitive offloading had little effect upon individuals’ subsequent unaided ability, leading to a small and nonsignificant drop in subsequent performance. However, there was a strong effect on participants’ subsequent likelihood of setting reminders. These findings suggest that the short-term impact of cognitive offloading is more likely to be seen on individuals’ strategy choices rather than basic memory processes.
