Kvalseth, Tarald O. (1988): Measuring Association for Nominal Data: Alternative Derivation and Interpretation of Lambda. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 1188-1190.

“Using the deviation-from-the-mode index of variation for categorical data, a measure of associate for numerical variables is derived. This measure (R{squared}) gives exactly the same numerical results as the popular lambda measure, but their derivations and operational interpretations differ. While lambda is based on a proportional-reduction-in-error logic, R{squared} is based on a proportional-reduction-in-variation logic analogous to the coefficient of determination for quantitative variables. Both asymmetric and symmetric R{squared} are considered.”

Kvalseth, Tarald O. (1987): Stimulus Probability, Surprise, and Reaction Time. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 147-150.

“This paper is concerned with the relationship between human reaction time for individual stimuli and their surprise values. A new measure of surprise is introduced that incorporates the probability of an individual stimulus occurring as well as the probabilities of the remaining potential stimuli. Experimental data are used to test the proposition that the reaction time for a stimulus is an increasing function of the surprise value of that stimulus. This proposition does indeed appear to be acceptable.”

Kvalseth, Tarald O. (1987): All-Terrain Vehicles: A Human Factors and Safety Analysis. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 760-761.

“This summary outlines the primary points of a paper concerning a human factors and safety analysis of the all-terrain vehicle (ATV). The ATV has become a popular consumer product and is being widely used in various work related environments. However, the safety of the different ATV designs is being seriously questioned, and the ATV related accident rates are showing alarming trends. In addition to giving such accident statistics, the paper to be presented will be concerned with various safety-related aspects of ATVs such as (1) the design of warning decals and owner's manuals, (2) safety devices, (3) thumb-operated versus twist throttles, (4) seat design, (5) luggage rack designs and (6) the unique operating characteristics and instability conditions. Two safety devices designed by this author and his students to prevent the ATV from tipping over backwards are discussed and the results of field test, and possibly a video demonstration, are presented.”
