Effects of light and heavy workload on air traffic tactical operations: A hazard rate model

Article Abstract:

Research into the effect of workload on air traffic control (ATC) has usually concentrated on the depleting effects on the psychological and physiological outcomes on air traffic controllers. A methodology to study how time influences decision-making and behavior is introduced, and used to look at how light and heavy air traffic workload affects ATC tactical operations. The results indicate that a dynamic model to assess ATC may be required, and that the implications of modular automation are not straightforward.

The effect of mental workload on the visual field size and shape

Article Abstract:

The visual field experiences increasing irregularity and decreasing circularity as mental workload increases. There are a number of possible explanations for this, including a bottleneck in response selection and execution and the involvement of pupil diameter. It is clear that there is a need for a more sensitive description of both visual field shape and size. Further research is required into the design implications of these findings, including object placement.
