This research paper explores how different drug mechanisms within a single class of drugs can produce different profiles of driving impairment. Prior research has failed to consider these mechanistic differences and often utilizes less controlled study methodologies. The potential impact of differing mechanistic effects is important for practitioners but remains unclear for most drugs. Twenty nine licensed drivers in good general health completed one of two miniSim™ studies using a validated, st...

Impaired driving due to drug use is a growing problem, worldwide; estimates show that 18-23.5% of fatal accidents, and up to 34% of injury accidents may be caused by drivers under the influence of drugs (Drummer et al., 2003; NHTSA, 2010; Walsh et al., 2004). Furthermore, at any given time, up to 16% of drivers may be using drugs that can impair one’s driving abilities (NHTSA, 2009). Currently, drug recognition experts (law enforcement officers with specialized training to identify drugged drivi...

Research on narrative persuasion has yet to investigate whether this process influences behavior. The current study explored whether: 1) a narrative could persuade participants to donate to a charity, a prosocial, behavioral decision; 2) psychophysiological metrics can delineate the differences between donation/non-donation behaviors; and 3) donation behavior can be correlated with measures of psychophysiology, self-reported reactions to the narrative, and intrinsic characteristics. Participants...

The current study examined EEG coherence across Coach-Learner dyads on a spatial reasoning video game, Tetris®, using an event-locked psychophysiological synching platform. We hypothesized that (1) an intra-individual increase in Theta and a decrease in high Alpha (10-12 Hz) fronto-temporal coherence would occur across increasing difficulty levels, and (2) inter-individual fronto-temporal coherence in high Alpha would increase among lower skilled players. A sample of n = 5 healthy dyads complete...

Previous research has shown that neonatal handling has prolonged protective effects associated with stress resilience and aging, yet little is known about its effect on stress-induced modulation of infectious disease. We have previously demonstrated that social disruption stress exacerbates the acute and chronic phases of the disease when applied prior to Theiler’s virus infection (PRE-SDR) whereas it attenuates disease severity when applied concurrently with infection (CON-SDR). Here, we asked ...

Objective: To identify psychophysiological indices of deadly force decision making in experts versus novices during simulator training.Background: Modern training techniques focus on improving decision-making skills with participative assessment between trainees and subject matter experts primarily through subjective observation. Objective metrics need to be developed. The current study explored the potential for psychophysiological metrics of decision making in deadly force judgment contexts. M...

The current study examined synchronous psychophysiological monitoring across a tutor and tutee during a spatial reasoning video game, Tetris®. We hypothesized that increased synchrony across tutor-tutee would correlate with increased performance (i.e. increased learning. A teaming platform enabled simultaneous electroencephalogram (EEG) and electrocardiogram (ECG) acquisition for the tutor-tutee dyad throughout the gaming sessions, using the B-Alert® X10 EEG system (Advanced Brain Monitoring, In...

This study aimed to identify the neurophysiological correlates of two primary aroused affective states related to positive and negative emotions, and to create a classification model for each second of data. General and individualized models were built on the EEG data recorded from 98 participants while watching two contrasting ~20 min videos – one to elicit a negative affective state, and the other to induce positive affect. The final models were cross-validated on an additional 63 participants...

Drowsy driving is a significant contributor to death and injury crashes on our nation's highways. Predictive neurophysiologic/physiologic solutions to reduce these incidences have been proposed and developed. EEG based metrics were found to be promising in initial studies, but remain controversial in their efficacy, primarily due to failures to develop replication studies within the simulation settings used for development, and real-world validation. This analysis sought to address these short c...

Objective: To identify benchmark neurophysiological measures that predict performance at a teaming level. Advanced Brain Monitoring has a track record of success in identifying neurophysiological metrics that impact expert behavior. For example, we characterized negative and positive predictors for marksmanship skill; persons with higher HF:LF Norm metrics of Heart rate variability (HRV, an indication of anxiety) during a benchmarking auditory passive vigilance task did not achieve expert marksm...
