Neural correlates of "absence" in interactive simulator protocols.

Area of Science:

• Neuroscience
• Psychology
• Human-Computer Interaction

Background:

• The importance of presence in virtual reality (VR) simulations is well-established.
• However, the role of fluctuating states of consciousness, or
• absence
• in VR experiences warrants deeper investigation.
• Subjective experience and neurophysiological processes during these fluctuations are critical for developing effective VR assessment and treatment tools.

Purpose of the Study:

• To propose that fluctuations in consciousness during interactive simulator tasks influence motivational engagement and performance.
• To highlight the relevance of factors like circadian rhythms, fatigue, and sleep intrusions in VR-based assessments.
• To emphasize the particular importance of these factors in patient populations with neurological and psychiatric disorders.

Main Methods:

• Review of experiments utilizing a standardized driving-simulation protocol.
• The protocol is designed for detecting psychomotor impairment in a clinical and diagnostic sleep laboratory setting.
• Examination of phenomena related to fluctuating consciousness during simulator tasks.

Main Results:

• Interactive simulator tasks are characterized by fluctuations in consciousness, impacting both motivation and performance.
• Factors such as circadian rhythms, fatigue, and sleep intrusions significantly affect outcomes in VR environments.
• These fluctuations are more pronounced and relevant in individuals with neurological and psychiatric disorders.

Conclusions:

• Consciousness in VR simulation is not a continuous state but fluctuates, affecting user engagement and performance.
• Considering these fluctuations is essential for accurate assessment and effective treatment using virtual environment-based tasks.
• The findings are particularly pertinent for clinical applications involving patients with neurological and psychiatric conditions.
