Age-related advantage for recall of complex naturalistic information following cognitive offloading

Abstract

Previous work on cognitive offloading has found that young and older adults create and use external memory aids to boost performance on simple memory-based tasks. To date, little work has investigated whether cognitive offloading can benefit performance when the memoranda are complex and naturalistic. In this study, 64 participants (32 young adults aged 18–26 years and 32 older adults aged 60+ years) studied facts about health conditions, then completed free recall and old-new recognition tests under two conditions. In the cognitive offloading choice condition, participants could create notes during study to use on upcoming memory tests. In the internal memory condition, participants had to rely on internal memory alone. Both age groups benefited from using cognitive offloading. Notably, older adults outperformed young adults on the free recall test when given the opportunity to offload. These results suggest that cognitive offloading can help older adults overcome everyday memory challenges.
