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 ...
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 ...
Clinical Assessment of Electromagnetic Compatibility of Hearing Aids and Digital Wireless Phones
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1998-10-01)
Research studies have shown that digital wireless phones interact with some hearing aids, creating a buzzing noise that may reduce speech intelligibility. Interference signals for three phone technologies were generated ...
The Use of Statistical Quality Control Charts to Evaluate Changes in Individual Performance
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1997-10-01)
An employee's readiness to perform (RTP) has become an important issue facing today's industries. Some industries have turned to cognitive performance testing to provide answers regarding their employee's abilities to work ...
A Test of Fitts' Law in a Dual-Task Paradigm
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1993-10-01)
A simulated automobile driving environment was used to assess the validity of Fitts' Law under dual-task conditions. An aimed hand movement task was used as the Fitts task representative of reaching for controls on an ...
