As individuals age, the cognitive demands of maintaining balance and gait increase, particularly when performing a secondary cognitive task, due to overlapping neural resources. This human factors research insight is drawn from a 2018 study published in Frontiers in Neurology. Using Focused review, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for older adults, prioritize simplicity and minimize cognitive load during activities requiring balance and mobility, as their cognitive resources are more heavily engaged in these tasks.

Key Findings
- 01Cognitive involvement in postural control and gait significantly increases with aging.
- 02Dual-task interference is greater when cognitive and motor tasks share neural circuits.
- 03Older adults may engage different neural substrates for cognitive-motor dual-task performance compared to younger adults.
- 04Age-related decline in sensory systems (vision, hearing) can contribute to increased cognitive load.
- 05Targeted cognitive training, exercise, and multimodal training can improve balance and gait in older adults.
Application
Design takeaway
When designing for older adults, prioritize simplicity and minimize cognitive load during activities requiring balance and mobility, as their cognitive resources are more heavily engaged in these tasks.
How to apply
When designing products for older adults that involve mobility or require attention (e.g., smart home devices, public transport interfaces, personal mobility aids), conduct user testing under dual-task conditions to assess cognitive load and potential interference with balance.
Project actions
- 01When designing for older users, consider how your product might interfere with their ability to focus on their surroundings or their physical movements.
- 02Think about how to make instructions or interactions as simple and intuitive as possible to reduce cognitive strain.

Variables
Strengths & Limitations
Strengths
- +Provides a comprehensive overview of cognitive-motor dual-tasking in aging from a neuroscience perspective.
- +Integrates findings from various studies to build a cohesive understanding of the phenomenon.
Limitations
The findings are based on a review, not direct experimentation. Real-world application might vary due to individual differences in health, experience, and environment.
Reliability & validity
The reliability and validity of findings in this review are dependent on the methodologies of the original studies. The review itself aims for validity by synthesizing a broad range of relevant literature. Future research with neuroimaging would enhance direct validity.
Think critically
How might the design of everyday objects or environments inadvertently increase cognitive load for older adults, thereby compromising their balance and gait?
Design Principles
"Minimize cognitive load during motor-intensive tasks for aging populations by simplifying interfaces and reducing distractions."
Understanding how cognitive load impacts motor performance in older adults is crucial for designing safer environments and assistive technologies. This insight informs the development of products and systems that account for age-related changes in attention and neural processing, aiming to enhance user safety and independence.
What This Means for Your Design
Older people need to think more to stay balanced and walk, especially if they are also trying to do something else with their brain. This is because their brain uses the same parts for thinking and moving, and these parts get tired or less efficient as people get older. Training their brains and bodies can help.
How to use in your project
- 1.This research can inform the user research phase by suggesting specific cognitive challenges to investigate in older user groups.
- 2.It provides a theoretical basis for analyzing user performance under dual-task scenarios.

Paragraph starter
This research highlights that as individuals age, the cognitive demands of maintaining balance and gait increase, particularly when performing a secondary cognitive task. This phenomenon is attributed to the principle of neural overlap, where shared neural resources between cognitive and motor tasks become a bottleneck with age. Consequently, designing products and environments for older adults requires a careful consideration of cognitive load to ensure safety and usability.
