Coefficient of Friction and Subjective Assessment of Slippery Work Surfaces
(Human Factors: The Journal of the Human Factors and Ergonomics Society, 1992-02-01)
Research was conducted to determine how well subjects could distinguish between surfaces with different coefficient of friction (COF) values and to evaluate how well subjective ratings of slipperiness correlated with the ...
Factor Structure of the Criterion Task Set
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1987-09-01)
A large-scale experimental study was conducted involving the training and testing of 123 human subjects on the Criterion Task Set (Version 1.0). Testing was performed under baseline and stressor conditions. The performance ...
Training Characteristics of the Criterion Task Set Workload Assessment Battery
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1985-10-01)
An evaluation of the Criterion Task Set was performed to determine the training requirements for the various tasks. Twenty subjects were divided into four groups. One group trained on all nine tasks in the battery. The ...
A Methodology for Investigating Heat Stress Selectivity Effects on Mental Performance
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1994-10-01)
This paper outlines a methodology that can be used to investigate the selectivity patterns of heat stress effects. The adopted view is that heat stress causes performance to deteriorate because it depletes attentional ...
Identification of Stable Asymptotic Performance on Computer-Based Cognitive Tests
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1998-10-01)
Examining whether human cognitive performance is affected by environmental conditions requires stable performance measures prior to stressor exposure. This study evaluated the stability and reliability of six computer-based ...
Diagnosis of Low Back Injury Using Strength Measurement
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1984-10-01)
A study was conducted to investigate the feasibility of using strength measurement as a diagnostic technique for assessing low back injuries involving symptomatic lumbar spine disease. The approach was to evaluate differences ...
Speed-Accuracy Tradeoffs in Spatial Orientation Information Processing
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1983-10-01)
A study was conducted to further evaluate the Manikin Task, a test of spatial orientation information processing. The objectives of the study were to determine the speed vs. accuracy tradeoff characteristics of the task ...
Application of a Predictive Coke Temperature Model to Heat Stress Experimentation
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1980-10-01)
An interactive procedure for evaluating and maintaining an individual's core temperature at a predetermined level was developed and tested. The procedure involved the use of previously developed models for predicting core ...
Development of the Criterion Task Set Performance Data Base
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1986-09-01)
The initial phase of a large-scale experimental study was conducted involving the training and testing of fifty human subjects on the Criterion Task Set (Version 1.0). Testing was performed under baseline conditions and ...
A Human Factors Perspective on Helicopter Human External Loads
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1999-09-01)
Human external loads (HEL) refer to operations where humans are transported while suspended below a helicopter. HEL operations are often required to access remote work sites, to access power lines in need of maintenance ...
