Inhibition Plasticity in Older Adults: Practice and Transfer Effects Using a Multiple Task Approach

Area of Science:

• Cognitive Neuroscience
• Gerontology
• Psychology

Background:

• Cognitive inhibition is crucial for executive functions.
• Understanding cognitive plasticity in older adults is vital for maintaining independence.
• Previous research suggests potential for cognitive training in older populations.

Purpose of the Study:

• To investigate the plasticity of cognitive inhibition in healthy older adults.
• To examine practice effects and transfer of training across different inhibition tasks.
• To utilize a multiple task approach to assess inhibition plasticity.

Main Methods:

• Forty-eight healthy older adults were divided into a practice group and a control group.
• The practice group engaged in three lab-based inhibition tasks over two weeks.
• Cognitive performance was assessed via pretest and posttest sessions.

Main Results:

• Significant improvements were observed in all three inhibition tasks post-practice, demonstrating plasticity.
• Training benefits transferred only to tasks with high structural and cognitive overlap (near-near transfer).
• Transfer effects to near-far and far-far tasks were inconclusive.

Conclusions:

• Older adults exhibit practice-induced plasticity in cognitive inhibition.
• Cognitive training gains are transferable to closely related tasks in older adults.
• The findings contribute to understanding targeted cognitive interventions for aging populations.
