Decision-Making Deficits in Elderly Can Be Alleviated by Attention Training

Area of Science:

• Cognitive Neuroscience
• Gerontology
• Psychology

Background:

• Decision-making abilities naturally decline with age.
• Value-based decision-making is crucial for everyday functioning.
• Cognitive training interventions are being explored to mitigate age-related cognitive deficits.

Purpose of the Study:

• To investigate if cognitive training can enhance value-based decision-making in the elderly.
• To compare the efficacy of selective attention training versus memory training on decision-making performance.

Main Methods:

• Elderly participants (62-75 years) were randomized into three groups: filter training (FT), memory training (MT), and a control group (CG).
• Training interventions (FT and MT) were conducted over five consecutive days.
• Performance was assessed using the Iowa Gambling Task (IGT), a decision-making simulation.

Main Results:

• The filter training (FT) group demonstrated significant improvement in IGT performance.
• FT led to increased overall gains and a reduction in the 'deck B phenomenon' (a disadvantageous decision-making pattern).
• Memory training (MT) and the control group (CG) did not show comparable improvements in IGT performance.

Conclusions:

• Selective attention training (filter training) appears to be a superior cognitive intervention for improving decision-making in older adults.
• Attention-based cognitive training may help counteract age-related impairments in value-based decision-making.
• Findings suggest that targeted cognitive training can enhance executive functions critical for daily life in the elderly.
