Method for Assessing the Influence of Phobic Stimuli in Virtual Simulators

Area of Science:

• Neuroscience
• Occupational Psychology
• Virtual Reality Simulation

Background:

• Phobic reactions are significant workplace risk factors often overlooked in professional training simulators.
• Assessing trainee stress responses, particularly phobias, is crucial for effective training design.

Purpose of the Study:

• To evaluate the impact of phobic stimuli on professional training quality.
• To investigate the relationship between phobic reactions and electroencephalogram (EEG) characteristics.
• To identify EEG metrics for detecting phobic reactions in trainees.

Main Methods:

• Experimental research involving virtual reality simulations with acrophobic and arachnophobic stimuli.
• Assessment of task performance metrics (time, accuracy, speed) and electroencephalogram (EEG) data (amplitude, power, coherence, Hurst exponent, interhemispheric asymmetry).
• Clustering algorithms and expert neurologist input for participant subgrouping and analysis.

Main Results:

• Phobic stimuli negatively impacted training quality for some participants.
• A significant relationship was identified between phobic reactions and specific EEG signal characteristics.
• EEG signal characteristics show potential as reliable metrics for detecting phobic reactions.

Conclusions:

• Virtual simulator design should incorporate phobia assessment to mitigate workplace risks.
• EEG analysis offers a viable method for identifying and quantifying phobic responses during training.
• Understanding the neurophysiological correlates of phobias can enhance training effectiveness and safety.
