Today’s warfighter performs more complex, cognitively demanding tasks than ever before. Despite the need for more extensive training to perform these tasks, acquisition professionals are often tasked to reduce training budgets and identify optimal tradeoffs. Tools are available to help them make these decisions that provide empirical evidence of how(More)
Approved for public release; distribution is unlimited. Approved for public release; distribution is unlimited. Human–computer interfaces (HCIs) have traditionally been structured according to a system's functional steps, which typically force human operators to adjust to an information organization that is foreign to them. In contrast, a task-centered HCI(More)
Imagery practice of motor tasks has been recommended for a wide range of activities as from flight training to basketball. A key question, both from a practical and a theoretical standpoint, is when during the learning process does imagery practice confer the most benefit? However, the literature does not provide clear guidance, in part because of(More)
The behavior of a four-member air defense warfare team composed of experienced crews from Aegis guided missile cruisers was simulated by a team of four computational models for the purpose of verification and validation of the modeled output with data from the human teams. The individual models are capable of communication and (hence) collaboration. They(More)
At present time most system engineers do not have access to cognitive work analysis knowledge or training in terms that they could understand and apply in the system design process. This may lead to specifying systems requirements that do not account for cognitive strengths and limitations of the prospective users. This paper proposes integration of(More)
