Background:

Air traffic controllers (ATCs) manage complex tasks with high cognitive load.
Understanding brain activity during critical tasks is essential for performance optimization.
Quantitative electroencephalography (qEEG) offers high temporal resolution for analyzing neural responses.

Purpose of the Study:

To investigate the relationship between visual and auditory cue responses, reaction times, and associated brain activity in ATCs.
To identify neural correlates of correct and incorrect responses during a continuous reaction task.
To assess the impact of visual versus auditory cueing on ATC performance and cognitive workload.

Main Methods:

Air traffic controllers performed an integrated visual and auditory continuous reaction task.
Quantitative electroencephalography (qEEG) was used to record brain activity.
Analysis focused on brainwave bands (theta, alpha, beta) and their ratios in relation to response accuracy and reaction time.

Main Results:

Correct visual responses correlated with theta band activity (frontal lobe), total power (parietal lobe), and theta-to-beta ratio (occipital lobe).
Incorrect visual responses showed additional alpha band activity (frontal and parietal lobes) and Sensorimotor Rhythm (parietal lobe).
Visual cues resulted in more accurate but slower responses compared to auditory cues.

Conclusions:

Air traffic controllers may experience cognitive overload with increased visual cues.
Increased auditory cues appear to reduce errors, suggesting a more efficient processing pathway.
Further workload studies are recommended to evaluate the impact and interaction of different cue types in air traffic control environments.
