Specifically, these pages are the main Outline of Contents page (ppsflevel2index.html) and the Overall Program Description page (ppsfprogdesc.html). I have already added to the Outline of Contents page the new URLs for the links to the "Cognitive Models..." and "Physiological Factors" pages which have already been placed. Also, please note that since I assumed that the Outline of Contents page would replace the current page at , the link on the Overall Program Description page back to the Outline of Contents page links back to that URL.

Psychological and Physiological Stressors and Factors

Overall Program Description

Background

The coming increase in air space utilization and the corresponding need to reduce the incidence of human and system errors is expected to place increasing stress on the human operators and decision makers who directly interact with the air transportation system. It is expected that existing technologies and procedures will be inadequate to alleviate this stress at minimum cost and to reduce the incidence of human error and potentially catastrophic system failure. Consequently, research into novel displays, controls, and procedures is required to explore innovative techniques for safe and efficient management of the increasingly dense air traffic system. This element is intended to spark this innovation. It is divided into three sub-elements: human perception, cognitive models and metrics, and physiological research.

Objectives

The Psychological/ Physiological Stressors and Factors research project goal is to develop new technologies and procedures to measure and reduce this increased stress within the air traffic system. Techniques will be developed to quantify the specific errors that the stress may cause. Knowledge will be developed that will enable innovative technologies and procedures that may be integrated into the national air transportation system to preserve its integrity. Stress is not simply considered to be the psychological stress of operators who have to deal with increasingly frequent takeoffs and landings, but it also includes the increasing visual clutter of the electronic displays they use and the increasing aural clutter of the audio channels. Research conducted on the enumerated elements below will 1) develop computational tools that will better allow the aeronautical community to analyze the perceptual fidelity of the human machine interfaces that they use, 2) assist analysis of perceptual problems with existing displays, and 3) explore the utility of revolutionary new perceptual display technology that may be adopted by the aeronautical community in the next century.

Approach

The Psychological/ Physiological Stressors and Factors research project uses analytical, experimental and actuarial methods to measure and predict human performance within all sectors of the nation's air transportation system. The human perception sub-element focuses on development of new methods, computational models, and metrics that will enable optimization of operator sensory-motor interaction with the displays and controls of the national air space system. The cognitive model sub- element focuses on models of the human operator information processing during interaction with the air transportation system with the goal of understanding how operator attention may focused or misfocused by the system. The physiological sub- element will consider the role of physiologically based variation in alertness and develop novel work rules to manage disturbances in operators' circadian rhythms while working within the air transportation system. This sub-element will also assess the impact of these innovative work rules. In addition to the usual publication of technical reports and scientific journal articles, the results of the research and development conducted under the Elements below will be disseminated to the aeronautical community through workshops and site visits organized and conducted by the principal investigators.
