Psychomotor Vigilance Performance: Neurocognitive Assay Sensitive to Sleep Loss
Clete A. Kushida in Sleep Deprivation, 2004
Accurate assessment of neurobehavioral performance capability during sleep deprivation protocols requires cognitive performance assays to be: (a) indicative of a fundamental aspect of waking cognitive function; (b) easily performed; (c) minimally affected by aptitude and learning; (d) as brief as possible; (e) valid and reliable; (f) sensitive; and (g) able to provide meaningful outcome variables that can be easily interpreted. In this chapter we have reviewed the evidence that the psychomotor vigilance task meets these requirements.

Vigilant attention was measured using the 3-minute Psychomotor Vigilance Task (PVT-B; Table 1) (Basner et al. 2011). The PVT-B requires participants to respond as quickly as possible to the presentation of a visual stimulus (3-digit millisecond counter). Inter-stimulus interval varied from 1000–4000 ms, with approximately 60 trials during the 3-minute task. This task is sensitive to the effects of sleep loss (Basner et al. 2011) and altered meal timing (Gupta et al. 2016), and has a minimal learning effect (Dorrian et al. 2004). Variables for analysis included the reciprocal of the mean response time (Mean RRT) and the mean number of lapses (lapse defined as a reaction time >355 ms). This task was completed before and after the 40-minute simulated drive as a measure of cognitive flexibility when required to switch back to a vigilant attention task after a sustained attention task.

Further, sleep problems decrease QOL and negatively influence health.17 Students have reported that emotional and academic stress had negative effects on sleep. Individuals classified as poor sleepers experienced more physical and mental health problems.18 Weekday sleeping time affects weekly sleepiness, nodding off while driving, exhaustion or depression symptoms, and academic achievement.19 Many college students experience chronic insomnia and report significantly worse fatigue, depression, anxiety, stress, and greater hypnotic and stimulant usage for sleep problems.2A previous study has shown that changes in sleep duration and poor cognitive function are related.20 Poor sleep efficiency was associated with worse Psychomotor Vigilance Task performance.21 Moreover, students experience lack of sleep and report different sleep patterns on weekdays and weekends, which contributes to academic failure.22

Cognitive performance was assessed using the Psychomotor Vigilance Task (PVT).50 The PVT was performed on two separate occasions. The PVT-192 was more specifically used. The AMI PVT-192 Psychomotor Vigilance Task Monitor is a hand-held, self contained system that stores repetitive reaction time measurements. There was an LCD display on the unit showing instructions and programable analog mood scales, buttons for the test selection, a microprocessor controlling the unit, solid state storage, and multiple subjects recording capability. The length of each test and the inter-stimulus intervals are fully programable. The PVT is a standard measure of reaction time commonly used to monitor change in performance.50,57 The results of the PVT are closely related to the ISI questionnaire as well as the time spent awaken by the participants.58 Previous research showed that a sleep restriction of only one hour can increase reaction time on this task.59 In addition, this type of cognitive decline (reaction time) has often been linked to the optimal functioning of the prefrontal cortex.60 For example, when the quality and quantity of sleep are reduced, one of the most affected areas is the prefrontal cortex.61,62 Each 5-minute trial consisted in the appearance of visual stimuli occurring at an interval of 2-10 seconds. Participants responded by pressing a button with their dominant thumb on the PVT-192 device. The PVT primary outcome of interest was the mean reaction time and the secondary outcomes of interest were maximum reaction time, minimum reaction time, false start and reaction time over 500 milliseconds.
