Computer-based, personalized cognitive training versus classical computer games: a randomized double-blind...

Area of Science:

• Gerontology
• Cognitive Neuroscience
• Human Computer Interaction

Background:

• Cognitive training is recognized for enhancing cognitive function in healthy older adults.
• Investigating personalized computerized cognitive training versus conventional computer games for efficacy.

Purpose of the Study:

• To compare the effectiveness of personalized computerized cognitive training against computer games in healthy older adults.
• To determine if personalized training yields superior cognitive gains.

Main Methods:

• A randomized, double-blind, interventional study involving 155 healthy older adults (mean age 68 ± 7 years).
• Participants were assigned to either personalized cognitive training or a computer games group.
• Cognitive performance was assessed pre- and post-intervention (3 months) using a neuropsychological battery; data analyzed via mixed effects models (adherence only and intention to treat).

Main Results:

• Both groups demonstrated cognitive improvements.
• Personalized cognitive training led to significant improvements in all 8 cognitive domains.
• Computer games showed significant improvements in 4 (adherence only) or 6 (intention to treat) domains.
• Personalized training was significantly more effective in enhancing visuospatial working memory, visuospatial learning, and focused attention.

Conclusions:

• Personalized computerized cognitive training offers greater benefits for cognitive performance in healthy older adults compared to computer games.
• Further research is warranted to explore the real-world applicability (ecological validity) of these cognitive enhancements.
