According to D. E. Broadbent's (1958) selective filter theory, people do not process unattended stimuli beyond the analysis of basic physical properties. This theory was later rejected on the basis of numerous findings that people identify irrelevant (and supposedly unattended) stimuli. A careful review of this evidence, however, reveals strong reasons to(More)
One of the most robust findings in attention research is that the time to name a color is lengthened markedly in the presence of an irrelevant word that spells a different color name: the Stroop effect. The Stroop effect is found even when the word is physically separated from the color, apparently indicating that words can be read outside the focus of(More)
NASA's Flight Deck Display Research Laboratory recently investigated air traffic automation designed to alleviate groundside workload in high traffic environments. This paper examines the data from post-experiment debriefings. We found that pilots are comfortable reviewing automated conflict resolutions, as well as modifying those resolutions before(More)
This document describes the second human-in-the-loop study in a series that examines the role of a ground operator in enabling single pilot operations (SPO). The focus of this study was decision-making and communication between a distributed crew (airborne pilot and ground operator). A prototype ground station and tools designed to enhance collaboration(More)
Since the 1950s, the crew required to fly transport category aircraft has been reduced from five to two. NASA is currently exploring the feasibility of a further reduction to one pilot. In this study we examine the effects of separating the pilots on crew interaction. The results are consistent with earlier research on decision-making between remote groups.(More)
The Federal Aviation Administration hopes to convert air traffic management to Trajectory Based Operations (TBO), under which aircraft flight plans are known to computer systems which aid in scheduling and separation. However, few aircraft flying today have equipment designed to support TBO. We conducted a human-in-the-loop simulation of TBO using current(More)
In this study, pilots were asked to achieve a specific time in trail while flying an arrival into Louisville International airport. Weather shortly before the start of the descent added variability to the initial intervals. A spacing tool calculated airspeeds intended to achieve the desired time in trail at the final approach fix. Pilots were exposed to(More)
