Abstract
BackgroundMetamemory training (MMT) is a useful training strategy for improving cognitive functioning in the older adult population. Despite the advantages, there are limitations imposed by location and time constraints.ObjectiveThis study aimed to develop a smart speaker–based MMT program and evaluate the efficacy of the program in older adults without cognitive impairment.MethodsThis study used a case-control cohort design. The smart speaker–based MMT program comprised 3 training sessions per day, 5 days a week, for 8 weeks. Each training session took approximately 15 minutes. This program was implemented using smart speakers, not human trainers. All participants completed the Mini-Mental State Examination, Subjective Memory Complaints Questionnaire, Verbal Learning Test, Digit Span Test, fluency tests, and a short-form version of the Geriatric Depression Scale before and after training.ResultsA total of 60 subjects (29 in the MMT group and 31 in the control group) participated in the study. The training group showed significant increases in the delayed free recall, digit span forward, digit span backward, and fluency test scores compared with the control group.ConclusionsThis study confirmed the efficacy of smart speaker–based MMT in older adults. Home-based smart speaker–based MMT is not limited with respect to location or constrained by space and may help older adults with subjective cognitive decline without requiring intervention by human professionals.
Highlights
MethodsThis study used a case-control cohort design
The gradual increase in the older adult population is leading to a growing problem with cognitive decline in the population.Many efforts have been made to address this concerning issue that is associated with older age.The term “metamemory” was introduced by Flavell [1] and it refers to a type of metacognition, meaning the knowledge and awareness of an individual's own memory, including the contents http://www.jmir.org/2021/2/e20177/ XSLFO RenderXJ Med Internet Res 2021 | vol 23 | iss. 2 | e20177 | p. 1 and processes of their memory system [2]
