Summary

Older adults showed notable improvement in working memory (WM) after dual n-back training, reaching young adult levels. While transfer effects were limited, this suggests WM training may help offset age-related cognitive decline.

Area of Science:

  • Cognitive Neuroscience
  • Gerontology
  • Psychology

Background:

  • Age-related decline in executive functions impacts daily autonomy.
  • Working memory (WM) training shows potential for cognitive plasticity in older adults.
  • Transfer of WM training effects to executive functions in older adults is understudied.

Purpose of the Study:

  • To investigate the effects of a dual n-back WM training task on executive functions in older adults.
  • To compare WM training outcomes and transfer effects in older adults versus young adults.
  • To assess the potential of WM training to compensate for age-related cognitive decline.

Main Methods:

  • Older adults (57-73 years) underwent a dual n-back training intervention (auditory and visual).
  • Training effects were assessed on the trained task and untrained WM updating tasks.
  • Performance was compared to young adults and previously reported data.

Main Results:

  • Both older and young adults improved on the dual n-back task; older adults' improvement was smaller but reached young adult baseline levels.
  • Older adults demonstrated transfer to an untrained WM updating task, consistent with young adult findings.
  • Other transfer effects to executive functions were not observed in older adults.

Conclusions:

  • WM training can lead to significant improvements in older adults' WM performance.
  • While broad transfer to executive functions was limited, WM training shows promise for mitigating age-related cognitive decline.
  • This study provides encouraging evidence for using WM interventions to enhance cognitive function in aging populations.
