Switching gears: Age-related differences in goal-directed and habitual behavior

Area of Science:

• Cognitive Psychology
• Neuroscience of Aging
• Behavioral Science

Background:

• Age-related cognitive decline impacts the ability to switch between goal-directed and habitual behaviors.
• Understanding these shifts is crucial for addressing behavioral changes in aging.

Purpose of the Study:

• To investigate cognitive factors influencing age-related differences in shifting between goal-directed and habitual behavior.
• To compare cognitive performance and behavioral control in younger and older adults.

Main Methods:

• Fifty participants (25 younger, 25 older adults) completed cognitive and well-being assessments.
• The symmetrical outcome-revaluation task measured goal-directed vs. habitual responding with varied response windows.
• Statistical analyses included t tests, ANOVAs, and ANCOVAs to compare age groups.

Main Results:

• Both age groups favored habitual behavior with short response windows.
• Younger adults successfully shifted to goal-directed behavior with longer windows; older adults did not.
• Working memory did not significantly explain performance differences between age groups.

Conclusions:

• Older adults' reliance on habitual responding is not solely due to age-related slowing or memory deficits.
• Further research is needed on interventions to support healthy behavioral change in older adults.
