[New methods of evaluation of the human-operator reliability]

Area of Science:

• Human factors engineering
• Cardiovascular physiology
• Neuroscience

Background:

• Assessing human operator reliability is crucial in high-stakes professions like air traffic control.
• Understanding the physiological correlates of operator performance can improve training and selection.
• Existing methods may not fully capture the dynamic responses of operators to stress.

Purpose of the Study:

• To evaluate new methods for assessing human operator reliability.
• To investigate the link between cardiovascular regulation and performance in air traffic control students.
• To identify physiological markers predictive of operator efficiency.

Main Methods:

• Recruited 27 students from the Air Traffic Control Faculty.
• Assessed sympathetic cardiovascular regulation during cold, hypoxic-hypercapnic exposure.
• Utilized a simulator to evaluate operator efficiency.
• Measured information perception using the competing fields of vision method.

Main Results:

• Subjects were categorized into 'reactive' and 'super-reactive' groups based on cardiovascular response.
• The 'reactive' group showed significantly better simulator performance.
• The 'super-reactive' group exhibited inadequate sympathetic reactions and parasympathetic overactivation during rest-to-work transitions.
• Information perception and nervous system plasticity were also assessed.

Conclusions:

• Sympathetic cardiovascular reactivity is a potential criterion for evaluating human operator reliability.
• Individuals with a 'reactive' cardiovascular profile may be better suited for high-pressure roles.
• Super-reactive individuals may require targeted interventions to manage stress responses and improve performance.
