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 ...
The Life Cycle and Quality Assurance of Performance Assessment Batteries
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2004-09-01)
As software products, computer-based performance assessment tasks and batteries cannot escape one of the cornerstones of software engineering – the software life cycle. This paper presents a discussion of the elements of ...
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 ...
Tactile Stimulation of the Human Head for Information Display
(Human Factors: The Journal of the Human Factors and Ergonomics Society, 1994-12-01)
A series of three studies was conducted to explore the use of tactile stimulation or light tapping of the human head to inform a pilot of possible threats or other situations in the flight environment. Study I confirmed ...
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 ...
Power Window Control Location Stereotypes
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1992-10-01)
A paper-and-pencil survey instrument and an operational test were used to assess stereotype strength for automobile power window controls. Control panel layout (square vs. linear) and mounting plane were examined along ...
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 ...
Evaluation of Static Work Capabilities in a Hot Environment
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1979-10-01)
The effects of heat stress on an individual's static work capabilities were investigated. Various indicators of strength and endurance were measured under differing heat stress levels. One measure which exhibited a significant ...
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 ...
