Home-Based Cognitive Intervention for Healthy Older Adults Through Asking Robots Questions: Randomized Controlled...

Area of Science:

• Gerontology
• Cognitive Neuroscience
• Human-Computer Interaction

Background:

• Assessing the impact of question-asking on older adults' cognition is challenging due to a lack of standardized home-based experimental methods.
• Previous research highlights the importance of cognitive training for healthy aging.

Purpose of the Study:

• To investigate the intervention effect of robot-moderated cognitive training on healthy older adults.
• To evaluate the feasibility of conducting such interventions in participants' homes.

Main Methods:

• A randomized controlled trial involving 81 adults over 65 years old.
• Intervention group: listened to stories and asked questions to robots. Control group: listened to stories and thanked robots.
• 12 dialogue sessions over 2-3 weeks, with cognitive tests administered before and after.

Main Results:

• No significant differences in cognitive functioning scores (global cognition, recall, verbal fluency) between groups.
• The study demonstrated high feasibility, with a 0% dropout rate.

Conclusions:

• Robot-moderated cognitive training, as implemented, did not show significant benefits for cognitive function in this cohort.
• Home-based cognitive interventions are feasible, but require refinement in session design for greater efficacy.
• Further research is needed to optimize question-asking-based cognitive interventions for older adults.
