BACKGROUND It is unclear whether and how elite athletes process physiological or psychological challenges differently than healthy comparison subjects. In general, individuals optimize exercise level as it relates to differences between expected and experienced exertion, which can be conceptualized as a body prediction error. The process of computing a body(More)
Extreme environments requiring optimal cognitive and behavioral performance occur in a wide variety of situations ranging from complex combat operations to elite athletic competitions. Although a large literature characterizes psychological and other aspects of individual differences in performances in extreme environments, virtually nothing is known about(More)
BACKGROUND Little is known about the neural basis of elite performers and their optimal performance in extreme environments. The purpose of this study was to examine brain processing differences between elite warfighters and comparison subjects in brain structures that are important for emotion processing and interoception. METHODOLOGY/PRINCIPAL FINDINGS(More)
Understanding the neural processes that characterize elite performers is a first step to develop a neuroscience model that can be used to improve performance in stressful circumstances. Adventure racers are elite athletes that operate in small teams in the context of environmental and physical extremes. In particular, awareness of team member's emotional(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)
Navy crews to complete time-critical 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 environment. The multi-task mission is characterized by multiple(More)
