“ ... there are no simple 'right' answers for most web design questions (at least not for the important ones). What works is good, integrated design that fills a need--carefully thought out, well executed, and tested. ”

Wilson, Glenn F., Estepp, Justin and Davis, Iris (2009): A Comparison of Performance and Psychophysiological Classification of Complex Task Performance. In: Proceedings of the Human Factors and Ergonomics Society 53rd Annual Meeting 2009. pp. 141-145.

“Psychophysiologically guided classifiers have been used to distinguish between low and high mental workload conditions. Prior studies used cognitive tasks that were quite different in terms of the cognitive demands placed on the operator. It is not clear if these classifiers can discriminate between tasks that are more similar in cognitive demand. A complex uninhabited aerial vehicle simulator provided conditions that were similar but placed emphasis on different aspects of the task. Performance and subjective workload data could only discriminate between the baseline task and the three more difficult tasks. Artificial neural networks (ANN) that used psychophysiological data were able”

Yolton, Robert L., Wilson, Glenn, Davis, Iris and McCloskey, Kathy (1987): Physiological Correlates of Behavioral Performance on the Mathematical Processing Subtest of the CTS Battery. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 770-773.

“To assess the relationship between behavioral, subjective and physiological measures of mental workload, 10 adult subjects solved equations with 1, 2 or 3 plus or minus operators (the Math Processing subtest of the CTS battery). Following extensive training, individual test sessions were held during which reaction times, subject workload ratings and a set of physiological measures were recorded. Reaction times and subjective workload ratings increased with the number of operators in the equations, but heart rhythm, eye blinks and peripheral temperature showed no systematic relationships to the number of operators. The P-300 event related potential decreased in amplitude and latency and a late position component recorded at Cz decreased in amplitude and increased in latency as the number of operators in the equations was increased.”

Wilson, Glenn F., Purvis, Brad, Skelly, June, Fullenkamp, Penny and Davis, Iris (1987): Physiological Data Used to Measure Pilot Workload in Actual Flight and Simulator Conditions. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 779-783.

“Three physiological measures of workload; heart rate, eye blink, and EEG were recorded from eight experienced A-7 attack aircraft pilots. Each pilot flew the same familiar training mission three times; one mission in the lead position of a four ship formation and the other as wing, and once in an A-7 simulator. The mission lasted approximately 90 minutes and consisted of take-off, low altitude terrain following, high G maneuvers, inflight navigational updates, weapons delivery, and a high altitude cruise to base, ending in a formation landing. The data show significant differences between simulated and actual flights for all measures. There were also significant differences between mission segments for each pilot. The heart rate data most obviously reflect the changes in workload level throughout the mission and between flight position and simulator. Blink rate and duration were sensitive to changing visual attentional demands. The EEG data showed differences between the actual flight missions and the simulator.”
