The effect of recent reminder setting on subsequent strategy and performance in a prospective memory task

Area of Science:

• Cognitive Psychology
• Human-Computer Interaction
• Neuroscience

Background:

• Technological advancements enable widespread cognitive offloading, shifting information storage from internal memory to external devices.
• This shift raises fundamental questions about the interplay between internal and external memory, and its potential benefits and costs.
• Understanding these dynamics is crucial in an increasingly digital world.

Purpose of the Study:

• To investigate the consequences of prior cognitive offloading on subsequent unaided memory ability.
• To examine how previous cognitive offloading influences strategic decisions regarding future use of external memory aids.
• To differentiate the effects of cognitive offloading on memory processes versus strategy selection.

Main Methods:

• Three pre-registered online experiments were conducted.
• Participants completed a web-based task involving remembering delayed intentions.
• The possibility of setting external reminders (cognitive offloading) was manipulated.

Main Results:

• Prior cognitive offloading had a minimal and nonsignificant negative effect on subsequent unaided memory performance.
• A significant increase was observed in participants' likelihood to engage in future cognitive offloading after prior use.
• Individuals' strategy choices were more affected than their basic memory processes.

Conclusions:

• Cognitive offloading primarily impacts strategic decision-making rather than core memory functions in the short term.
• Individuals adapt their strategies based on the availability and prior use of external memory aids.
• Future research should explore long-term effects and individual differences in cognitive offloading.
