PC-PVT 2.0: An updated platform for psychomotor vigilance task testing, analysis, prediction, and visualization.

Area of Science:

• Neuroscience
• Cognitive Psychology
• Human Performance

Background:

• The psychomotor vigilance task (PVT) is crucial for assessing sleep deprivation's impact on neurobehavioral performance.
• Previous development of PC-PVT offered real-time analysis and visualization for PVT research.
• The PC-PVT system is analogous to the gold-standard PVT-192.

Purpose of the Study:

• To introduce PC-PVT 2.0, an updated software for Windows 10.
• To enable coupling of PVT tests with sleep/wake and caffeine schedules.
• To provide real-time, individualized predictions of PVT performance.

Main Methods:

• Characterized the accuracy and precision of PC-PVT 2.0 in measuring reaction time (RT).
• Evaluated 44 distinct personal computer (PC) hardware configurations.
• Utilized a gaming mouse for stimulus response to minimize delay.

Main Results:

• 15 system configurations achieved RT measurement delays under 10 ms, comparable to PVT-192.
• Recommended specific hardware configurations (gaming mouse, discrete GPU, external monitor) for optimal performance.
• Demonstrated the software's capability to integrate study schedules and predict performance.

Conclusions:

• PC-PVT 2.0 enhances PVT analysis, visualization, and prediction for sleep-loss studies.
• The software facilitates near-real-time, individualized performance predictions considering caffeine effects.
