Chin, Anpin and Bishu, Ram R. (1994): Effect of Task Difficulty on Fault Diagnosis Strategy. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. p. 978.

“The application of appropriate strategies is the key in fault diagnosis. Most studies on fault diagnosis have paid attention to complexity simplification, and various approaches have been studied to assist humans in overcoming difficulties. Interface design and training are two main directions to improving human performance in fault diagnosis. A number of visual aiding tools have been designed to decrease the effect of perceptual complexity. With a set of topographic search tasks, this study evaluates the efficacy of two typical strategies, linear tracing strategy and structure decomposing strategy, on different levels of task difficulty. Fifteen subjects participated in a factorial experiment. The highlighting aiding tool designed from the Linear-Tracing (LT) strategy was preferred by the subjects because of the advantage of saving time, but this tool resulted in lower accuracy in decision-making. Although all the subjects were instructed to pay attention to the accuracy rather than the speed, the problem of changing the focus from accuracy to speed usually occurred while using the highlighting tool. The blocking tool designed from the Structure Decomposing strategy (SD) provided higher accuracy but took time. The physiological decline caused by aging showed no effect on the accuracy but resulted in speed loss. Another finding showed that the effect of perceptual complexity might not be fully determined by the size of the test problem, but by the average amount of pertinent input/output signals of feasible components in such a topography search task.”
