Multi-domain training enhances attentional control

Area of Science:

• Cognitive Neuroscience
• Gerontology
• Psychology

Background:

• Multi-domain training may enhance cognitive transfer by increasing overlap with everyday tasks.
• Older adults often experience declines in executive functions, impacting daily life.
• Previous research has not systematically compared multi-domain training with single-domain conditions.

Purpose of the Study:

• To investigate the effectiveness of multi-domain cognitive training compared to single-domain training in healthy older adults.
• To assess near and far transfer effects of cognitive training on executive functions.
• To determine if cognitive training benefits individuals with lower baseline performance.

Main Methods:

• 84 healthy older adults (64-75 years) were randomized into multi-domain or single-domain (inhibition, visuomotor, spatial navigation) training groups.
• Participants completed 50 iPad-based training sessions at home.
• Cognitive functioning and transfer were assessed pre-training, post-training, and at 6-month follow-up using neuropsychological tests.

Main Results:

• All groups showed improved training performance.
• The multi-domain training group demonstrated significantly greater improvement in attentional control (far transfer) compared to single-domain groups.
• Training gains were stable at the 6-month follow-up.
• Individuals with lower initial cognitive performance showed greater training-induced improvements.

Conclusions:

• Multi-domain cognitive training is a promising approach for enhancing executive functions, specifically attentional control, in older adults.
• This training may help older adults manage complex daily tasks requiring simultaneous attention.
• Cognitive training can compensate for age-related cognitive declines.
