“ ... 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. ”

Esses, Gregory A. and Malmstrom, Frederick V. (1995): Officers Are in Better Physical Condition, Especially Middle-Age Males. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. p. 947.

“We compared physical fitness scores of 225 active duty Air Force Materiel Command personnel utilizing the results of the controversial bicycle ergometer test. When compared to a previous Army 2-mile running test, the Air Force results seem consistently to have a great deal more variability (and, therefore, lower validity). Possible reasons for this decreased reliability may lie in the inherent lower validity of the Astrand bicycle ergometer test. Most interestingly, when we analyzed the bicycle ergometer estimated V02 -- max scores, male officers seemed to be in significantly better physical condition than all other groups, especially the middle age field grade officers. Reasons for this unexpected superior performance are discussed, including possible lifestyle differences such as decreased cigarette smoking and individual motivation.”

Malmstrom, Frederick V., Perez, William A. and Brezovic, Christopher P. (1987): Estimating Positions and Speeds of Objects on the CRT After the Screen Goes Blank. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 1202-1205.

“In this study, 24 subjects with 20/20 correctible vision participated in a 3 x 3 x 2 visual estimation experiment. The stimulus was a dot or "ball" bouncing clockwise around a 12° visual angle square according to laws of ideal physics. At the end of the first collision, the ball disappeared, and subjects were then required to estimate where on each wall the ball would subsequently impact. The ball was presented at speeds of 3.5°, 6.7°, 10.0° visual angle/sec. Results indicated that there was a linear relationship in the times required to estimate the positions of the ball after 1, 2, and 3 bounces; however, the positional accuracy deteriorated rapidly after 3 bounces and about 8 seconds. Results also suggested that the speed at which the moving stimulus is observed also influences the speed at which one later imagines the moving object. We believe there is a "default" speed at which subjects optimally prefer to imagine moving objects, and that speed is around 5° to 8° of visual angle/sec. We suggest that simple motion presented on CRT displays might be accurately projected ahead by the subject when it is presented at this default speed.”
