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)
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)
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)
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)
<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)
Use of unmanned aerial vehicles (UAVs) is an increasingly important element of military missions. However, controlling UAVs may impose high stress and workload on the operator. This study evaluated the use of the RoboFlag simulated environment as a means for profiling multiple dimensions of stress and workload response to a task requiring control of(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)
OBJECTIVE The aim of this study was to examine the effects of uncertainty about where in the field of view critical signals for detection appear during a vigilance task (spatial uncertainty) on cerebral blood flow velocity (CBFV) and oculomotor fatigue. BACKGROUND Neuroergonomics is a dimension of human factors founded by Raja Parasuraman that studies(More)
