“…It may reflect the greater interest and challenge provided by working on a complex, gamelike task. Parsons, Warm, Nelson, Riley, and Matthews (2007) showed that increasing the operator's level of control over task events increases task engagement. Thus, synthetic task environments may have advantages over simple laboratory tasks as a methodology for investigating stress responses elicited by complex operational tasks.…”

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 multiple vehicles (robots). It tested the effects of two workload manipulations, environmental uncertainty (i.e., UAV's visual view area) and maneuverability, in 64 participants. The findings confirmed that the task produced substantial workload and elevated distress. Dissociations between the stress and performance effects of the manipulations confirmed the utility of a multivariate approach to assessment. Contrary to expectations, distress and some aspects of workload were highest in the low-uncertainty condition, suggesting that overload of information may be an issue for UAV interface designers. The strengths and limitations of RoboFlag as a methodology for investigating stress and workload responses are discussed.

“…Participants were also prevented from controlling the direction of movement, and they could not pan their viewpoint to any direction other than that preset. They were thus prevented from actively exploring the environment, which itself can influence observer' response (Gunn et al 2005;Parsons 2007). …”

“…Allowing some scope for personal configuration of the system may be valuable. Parsons et al (2007) compared two versions of a vigilance task, presented in a military context. Participants were required either to simply register detection of symbols representing enemy missile launchers or to additionally acquire and destroy the target using a mouse response, following detection.…”

Individuals differ considerably in their vulnerability to task-induced stress, in part because of individual differences in cognitions of task demands. This study investigated the personality and cognitive factors that may control stress vulnerability, using a 'rapid information processing' task that was configured to overload attention. Stress response was assessed using the Dundee Stress State Questionnaire . Fundamental dimensions of subjective state in performance settings: task engagement, distress and worry. Emotion, 2, 315-340), as well as instruments assessing workload, appraisal and coping. Time pressure was manipulated as a between-subjects stress factor. Higher time pressure tended to elicit decreased effort and task engagement and avoidance coping. However, much of the variance in state response was attributable to individual differences in appraisal and coping. The personality trait of neuroticism related to some of these cognitive processes. Subjective state, appraisal and coping were also predictive of objective performance indices. Consistent with the transactional theory of stress, subjective states appear to correspond to configurations of cognitive processes that signal the participant's mode of adaptation to task demands. The findings underscore the importance of accommodating individual differences in selecting operators for handling overload, for designing interfaces and for training operators to manage overload successfully.
