Konrad, Christopher M., Kramer, Arthur F. and Watson, Stephen E. (1994): A Comparison of Sequential and Spatial Displays in a Complex Monitoring Task. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 1331-1335.

“A sequential or RAP COM display was compared to a more conventional spatial display as subjects monitored dynamically changing sets of numbers and responded to occasional target stimuli. In an effort to equate the stimulus-response compatibility of the two displays subjects responded to the targets with a chord keyboard. We examined the influence of display duration on the performance with the RAP COM and spatial formats by presenting the stimuli at three different durations, 400, 800 and 1200 msec. The influence of practice on performance with the RAP COM and spatial displays was also investigated. Targets were responded to more quickly in the RAP COM than in the spatial displays at each of the three presentation durations and across over 2000 trials of practice. Accuracy was influenced by the display presentation duration. Accuracy was higher for the RAP COM than the spatial display at the 800 msec stimulus presentation duration. Accuracy was statistically equivalent for the RAP COM and spatial display format at the 400 and 1200 msec display durations, although there was a trend for lower accuracy for the RAP COM display at the faster presentation duration. Interestingly, the lower accuracy for the RAP COM display format at the 400 msec presentation duration appears to be due to illusory conjunctions. Our results will be discussed in terms of the utility of sequential or RAP COM displays in complex, real-world settings.”
