Cognitive Flexibility Training: A Large-Scale Multimodal Adaptive Active-Control Intervention Study in Healthy Older...

Area of Science:

• Neuroscience
• Gerontology
• Cognitive Psychology

Background:

• Aging commonly leads to cognitive decline, particularly in executive functions.
• Online cognitive training is a popular but controversial intervention for older adults.
• Evidence for far transfer and long-term maintenance of cognitive gains is limited.

Purpose of the Study:

• To investigate the efficacy of a novel, adaptive cognitive training program (TAPASS) in healthy older adults.
• To assess training-specific effects on executive functioning and other cognitive domains.
• To explore individual factors influencing training benefits.

Main Methods:

• A randomized controlled trial (TAPASS) involving healthy older adults (60-80 years).
• Three groups: frequent switching, infrequent switching, and an active control group.
• 58 sessions of 30 minutes each over 12 weeks, with cognitive assessments at four time points.

Main Results:

• Significant time effects (likely retest effects) observed on transfer tasks across all groups.
• No training-specific improvements in executive functioning or other cognitive measures were detected.
• Individual characteristics did not yield additional training benefits.

Conclusions:

• The therapeutic value of current cognitive training games for the aging brain appears modest.
• Observed effects may be attributed more to expectancy and motivation than to training components.
• Emphasizes the need for parallel tests for transfer assessment and active control groups; suggests future research on varied, social, and adaptive training methods.
