Wong, Clifford K. and Lyman, John (1988): American and Japanese Control-Display Stereotypes: Possible Implications for Design of Space Station Systems. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 30-34.

This study examined the stimulus-response stereotypes of American (United States citizens) and Japanese (Japanese citizens) subjects on the issue of control-display arrangements. Three questions were investigated. First, do Japanese and Americans operators adhere to the same compatibility principles, e.g., clockwise-for-increase, for certain configurations? Second, do the operators show similar or different responses to certain configurations? Third, are there arrangements in which both populations show strong or weak stimulus-response stereotypes? A paper and pencil test that contained 24 different control-display configurations was administered to 58 American subjects and 58 Japanese subjects, all of whom were right-handed. Out of the 24 configurations, only one elicited similar and statistically significant response stereotypes from American and Japanese subjects. The arrangement that did so emphasized that three compatibility principles (clockwise-for-increase, nearness of control-cursor relation, and scale-side) be in agreement with each other. The results provide initial, albeit speculative, guidelines for the design of control-display systems in NASA's international space station. Since multicultural crews will inhabit the space station for long duration missions, control-display designs which elicit common, consistent, and extremely strong control-movement stereotypes from different cultural populations is a necessity.

Wong, Clifford K. and Lyman, John (1987): Distributed Situation Assessment under Varying Environmental Conditions. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 1360-1364.

This paper describes a study that is currently examining distributed problem solving performance in a simulated, dynamic battlefield situation assessment task, using computers as the interface between problem solvers and the simulated environment. There are four objectives of this study. First, identify any possible heuristics or strategies used by the group members in dealing with the problem. Second, observe how distributed situation assessment performance varies with environmentally imposed demands. Third, study human communication in both stressed and unstressed situations. Finally, examine how specific group communication protocols employed under different environmental conditions influence situation assessment performance. Thus, the overall objective of the study is to help identify and characterize human problem solving performance and human-machine performance characteristics that emerge when a computer intermediary resource is made an integral part of a distributed problem solving situation.
