Changes in six measures of eye activity were assessed as a function of task workload in a target identification memory task. Eleven participants completed four 2-hr blocks of a mock anti-air-warfare task, in which they were required to examine and remember target classifications (friend/enemy) for subsequent prosecution (fire upon/allow to pass), while(More)
Individuals who perform optimally in extreme conditions, such as elite military warriors, can provide valuable insight into the neurobehavioral mechanisms underlying extraordinary performance. In the current study, we examined the degree to which Navy SEALs, when compared with healthy volunteers, could show more right anterior insula activation when(More)
The primary focus of this research effort was the tracking of eye movements during complex cognitive tasks. 8 volunteers performed a visual tracking task alone and a combination of the visual task and the auditory Paced Serial Addition Task (PASAT). Results showed a reduction in range on the order of 50% for eye movements and an increase in variability of(More)
Watchstanding in shipboard command centers requires U.S. Navy crews to complete timecritical and externally paced task assignments in an accurate and timely manner. Requirements for optimized crew sizes in future ships are driving system designers toward human–computer interface designs that mitigate task and workload demands in a multi-task work(More)
The DARPA Augmented Cognition program is developing innovative technologies that will transform the person–machine interaction by making information systems sensitive to the capabilities and limitations of the human component of the person–machine system. By taking better advantage of individual human capabilities, and being sensitive to human limitations,(More)
