“…FAT scores are calculated by dividing the variance in scores by the mean reaction time. Higher cue utilization is associated with a greater ratio of variance to reaction time (Morrison, Wiggins, Bond, & Tyler, 2013; Schvaneveldt, Beringer, & Lamonica, 2001).…”

Objective: This study was designed to examine whether cue utilization differentiates drivers’ consumption of cognitive resources during a simulated driving task. Background: Outcomes from previous research have demonstrated that a general capacity for cue utilization differentiates cognitive load during novel process control tasks. However, it was previously unclear whether similar results would be demonstrated during familiar operational tasks. Method: Based on an assessment of cue utilization within a driving context, participants were classified into higher or lower cue utilization typologies. During a simulated driving task, cognitive load was assessed through changes against baseline in cerebral oxygenation in the prefrontal cortex, through eye behavior metrics (fixation rates and fixation dispersion), and through driving performance (frequency of missed traffic signals and speed exceedances). Results: Drivers with higher cue utilization recorded smaller mean fixation dispersions, smaller increases in cerebral oxygenation, and fewer missed traffic signals compared with drivers with lower cue utilization. These results suggest that compared with drivers with lower cue utilization, drivers with higher cue utilization experienced lower cognitive load during the simulated driving task while maintaining a higher level of performance. Conclusion: The results provide support for the assertion that, among qualified operators, a greater capacity for cue utilization is associated with lower cognitive load during operational tasks. Application: Cue-based assessments of driving may be beneficial in predicting performance and assisting in targeted training for recently qualified and/or older drivers.

“…The data were formatted in a proximity data file (similar to the JRate export). The exported proximity data were analyzed and used to generate the PFNET (discussed in Results) through JPathfinder, 73 a freely available software tool to explore and visualize PFNETs. Figure 6 summarizes the process of creating the proximity data for the seed concepts.…”

The human papillomavirus (HPV) vaccine protects adolescents and young adults from 9 high-risk HPV virus types that cause 90% of cervical and anal cancers and 70% of oropharyngeal cancers. This study extends our previous research analyzing online content concerning the HPV vaccination in social media platforms used by young adults, in which we used Pathfinder network scaling and methods of distributional semantics to characterize differences in knowledge organization reflected in consumer- and expert-generated online content. The current study extends this approach to evaluate HPV vaccine perceptions among young adults who populate Reddit, a major social media platform. We derived Pathfinder networks from estimates of semantic relatedness obtained by learning word embeddings from Reddit posts and compared these to networks derived from human expert estimation of the relationship between key concepts. Results revealed that users of Reddit, predominantly comprising young adults in the vaccine catch up age-group 18 through 26 years of age, perceived the HPV vaccine domain from a virus-framed perspective that could impact their lifestyle choices and that their awareness of the HPV vaccine for cancer prevention is also lacking. Further differences in knowledge structures were elucidated, with implications for future health communication initiatives.

“…For example, initiating a roll will cause a decrease in pitch, as a consequence of the change in direction of the lift vector. Secondly, when direct perception of the environment is unavailable (in low visibility conditions, termed instrument meteorological conditions) flying is a radically different and more challenging task (Gibb, Gray, & Scharff, 2010; Schvaneveldt, Beringer, Lamonica, Tucker, & Nance, 2000). In these conditions, pilots must derive the values of the aforementioned flight variables from discrete, spatially separated cockpit instruments.…”

Landing an aircraft is a complex task that requires effective attentional control in order to be successful. The present study examined how anxiety may influence gaze behavior during the performance of simulated landings. Participants undertook simulated landings in low visibility conditions which required the use of cockpit instruments in order to obtain guidance information. Landings were performed in either anxiety or control conditions, with anxiety being manipulated using a combination of ego-threatening instructions and monetary incentives. Results showed an increase in percentage dwell time toward the outside world in the anxiety conditions. Visual scanning entropy, which is the predictability of visual scanning behavior, showed an increase in the randomness of scanning behavior when anxious. Furthermore, change in scanning randomness from the pre-test to anxiety conditions positively correlated with both the change in cognitive anxiety and change in performance error. These results support the viewpoint that anxiety can negatively affect attentional control.
