Cognitive ability, expertise, and age differences in following air-traffic control instructions

Area of Science:

• Aviation Psychology
• Human Factors Engineering
• Cognitive Aging

Background:

• Pilot performance can vary with age and expertise.
• Cognitive abilities, such as working memory, are crucial for complex tasks like aviation communication.

Purpose of the Study:

• To investigate the relationship between pilot age, expertise, and performance on simulated air traffic control communication tasks.
• To explore the cognitive mechanisms, specifically working memory, underlying age-related differences in pilot performance.

Main Methods:

• Pilots of varying ages and expertise levels performed simulated air traffic control communication tasks.
• Message complexity was manipulated through variations in length and speech rate.
• Pilot accuracy and cognitive measures (working memory span, speed, interference control) were assessed.

Main Results:

• Older pilots demonstrated lower accuracy in executing air traffic control messages.
• Pilot expertise was associated with higher accuracy but did not mitigate age-related performance differences.
• Age-related decrements in accuracy were significantly mediated by reduced working memory span, including speed and interference control.

Conclusions:

• Age-related declines in pilot communication accuracy are primarily mediated by cognitive factors, particularly working memory capacity.
• While expertise enhances performance, it does not fully compensate for age-associated cognitive changes in this context.
• Findings highlight the importance of cognitive support and training strategies to address age-related challenges in aviation.
