Summary
This study investigated audiovisual stimulation effects on brain activity and autonomic function, linking mental tendencies to physiological responses. Results suggest autonomic function influences reactions to stimuli, potentially enabling pre-screening for adverse effects.
Area of Science:
- Neuroscience
- Psychophysiology
- Broadcasting Safety
Background:
- The "Pockemon shock" incident highlighted risks of audiovisual stimulation.
- Understanding psychological and psychosomatic responses is crucial for broadcasting safety.
Purpose of the Study:
- To investigate the relationship between autonomic function, mental tendencies, and physiological responses to audiovisual stimuli.
- To explore potential methods for screening individuals susceptible to adverse reactions.
Main Methods:
- Utilized a head-mounted display and a shooting game for audiovisual stimulation.
- Measured brain oxygen metabolism (near-infrared spectroscopy) and electrocardiograms in healthy adult males.
- Assessed psychological factors using Type A/B behavior patterns, hostility scales, and the Minnesota Multiphasic Personality Inventory (MMPI).
Main Results:
- No fatal arrhythmias or epilepsy were observed; physiological data remained within normal ranges.
- Significant negative correlations found between heart rate variability (HRV) components (HF, LF/HF) and lie scale/social support quantity.
- Autonomic function (sympathetic/parasympathetic nervous system activity) showed connections to mental tendencies.
Conclusions:
- Autonomic function appears linked to mental tendencies, influencing reactions to audiovisual stimuli.
- Findings suggest a potential for pre-screening individuals prone to morbid audiovisual responses.
- This research contributes to understanding psychophysiological reactions in broadcasting and gaming contexts.
