Just write it down: Similarity in the benefit from cognitive offloading in young and older adults.

Past research conducted primarily in young adults has demonstrated the utility of cognitive offloading for benefitting performance of memory-based tasks, particularly at high memory loads. At the same time, older adults show declines in a variety of memory abilities, including subtle changes in short-term memory, suggesting that cognitive offloading could also benefit performance of memory-based tasks in this group. To this end, 94 participants (62 young adults, 32 older adults) were tested on a retrospective audiovisual short-term memory task in two blocked conditions. Offloading was permitted in the offloading choice condition but not in the internal memory condition. Performance was improved for both age groups in the offloading choice condition compared to the internal memory condition. Moreover, the choice to use the offloading strategy was similar across age groups at high memory loads, and use of the offloading strategy benefitted performance for young and older adults similarly. These data suggest that older adults can make effective use of cognitive offloading to rescue performance of memory-based activities, and invites future research on the benefits of cognitive offloading for older adults in other, more complex tasks where age-related memory impairment is expected to be more prominent.
