Cognitive performance, rather than age, influences the trial-and-error learning benefits in an execution task.

Area of Science:

• Cognitive Neuroscience
• Rehabilitation Science

Background:

• Efficient learning methods are crucial for cognitive rehabilitation.
• Trial-and-error (T&E) learning and its executive function underpinnings are less understood than errorless learning, particularly in older adults.

Purpose of the Study:

• To investigate learning adaptation involving executive function in older individuals using a novel error correction task.
• To analyze the relationship between cognitive performance, age, and T&E learning outcomes.

Main Methods:

• Developed a chip task requiring self-error correction based on feedback.
• Assessed 50 older participants over seven execution task sessions.
• Defined learning outcome by chip replacements needed for correct answers in final sessions.

Main Results:

• T&E learning outcomes were significantly associated with cognitive performance.
• Age was not a significant factor in T&E learning outcomes.
• Older individuals' learning adaptation was driven by cognitive function, not chronological age.

Conclusions:

• T&E learning adaptation in older adults is contingent on cognitive performance, highlighting the role of executive functions in error management.
• Older individuals can improve error management through self-correction, dependent on their residual cognitive capacities.
• Learning interventions, especially T&E methods, should be individualized based on cognitive abilities to optimize rehabilitation outcomes.
