In this investigation, eight Air Force air traffic controllers (ATCs) performed three scenarios on TRACON (Terminal Radar Approach Control), a computer-based air traffic control (ATC) simulation. Two scenarios were used each with three levels of difficulty. One scenario varied traffic volume by manipulating the number of aircraft to be handled and the(More)
This study examined whether alpha event-related desynchronization (ERD) and theta event-related synchronization (ERS) could successfully measure changes in cognitive workload and training while an operator was engaged in a continuous, interactive, control task(s). Alpha 1 (8-10 Hz) ERD, alpha 2 (10-12 Hz) ERD, and theta (3-7 Hz) ERS were determined for a(More)
EEG changes related to the amount of information held in memory during a 4-s retention period were studied. The predictability of the amount of information held in memory was varied. In the weighted condition, 60% of the trials contained only one item and the remaining 40% of the trials were evenly distributed between trials containing 3, 5, 7, or 8 items.(More)
A series of experiments were conducted to systematically evaluate the relative contributions of task difficulty and stimulus probability to P300 amplitudes. Scalp event-related potentials (ERPs) were recorded and the topographic distributions were evaluated during a multi-level cognitive task with an antecedent warning. In three separate studies, task(More)
In today's world it is quite common to see old ideas repackaged and presented to consumers in sleek new containers. This repackaging also occurs in the educational realm. For example, the violence seen in schools has prompted the call for character education, media literacy, and conflict resolution training. Many of these instructional programs, although(More)
Today, engineering and media cultures do indeed combine in entertainment computing productions. A shared culture has emerged. All day long, team members at all levels make judgments that are both inherently technical and creative. Technology largely enabled this cultural shift from the early 1990s to today, with the analog media formats all becoming digital(More)
