Emotional intelligence (EI) may predict stress responses and coping strategies in a variety of applied settings. This study compares EI and the personality factors of the Five Factor Model (FFM) as predictors of task-induced stress responses. Participants (N = 200) were randomly assigned to 1 of 4 task conditions, 3 of which were designed to be stressful.(More)
Transcranial Doppler sonography was used to measure cerebral blood flow velocity (CBFV) in the right and left cerebral hemispheres during the performance of a 50-min visual vigilance session. Observers monitored a simulated flight of unmanned aerial vehicles for cases in which one of the vehicles was flying in an inappropriate direction relative to its(More)
OBJECTIVE In the present study, we explored the state versus trait aspects of measures of task and team workload in a disaster simulation. BACKGROUND There is often a need to assess workload in both individual and collaborative settings. Researchers in this field often use the NASATask Load Index (NASA-TLX) as a global measure of workload by aggregating(More)
Research indicates that coactors performing cooperative tasks often exhibit spontaneous and unintended similarities in their physiological and behavioral responses--a phenomenon referred to here as physio-behavioral coupling (PBC). The purpose of this research was to identify contributors to PBC; examine relationships between PBC, team performance, and(More)
OBJECTIVE The purpose of this article is to present and expand on current theories and measurement techniques for assessing team workload. BACKGROUND To date, little research has been conducted on the workload experienced by teams. A validated theory describing team workload, which includes an account of its relation to individual workload, has not been(More)
OBJECTIVE In this study, we evaluated the validity of the Sustained Attention to Response Task (SART) as a means for promoting mindlessness in vigilance performance. BACKGROUND Vigilance tasks typically require observers to respond to critical signals and to withhold responding to neutral events. The SART features the opposite response requirements, which(More)
<b>Motivation</b> -- To address the effects of spatial processing load and text-based collaborative tools on team performance in command and control environments. <b>Research approach</b> -- Thirty-two people served as paid participants in this study. Teams of two participants competed against a computer opponent in a RoboFlag simulation based on(More)
Previous research has revealed that the behavioral dynamics of joint-action can naturally emerge from the physical and informational constraints that define a shared task-goal. The emergence of complementary actions or functional differences in control also appear to be a natural part of such behavior, and are often an inherent aspect of robust and highly(More)
The development of closed-loop systems is fraught with many challenges. One of the many important decisions to be made in this development is the selection of suitable metrics to detect operator state. Successful metrics can inform adaptations in an interface’s design, features, or task elements allocated to automated systems. This paper will discuss(More)
