The proximity-compatibility principle (PCP) proposed by Wickens and Carswell (1995) is examined on the basis of experimental results obtained with the process-control micro-world AUTO-CAMS. The PCP postulates a performance trade-off in display design that implies that display features that support information integration may degrade focused attention. In AUTO-CAMS information integration is required when operators, in case of system failures, have to engage in fault identification by mapping multiple anomaly symptoms to single root causes. Focused attention is demanded by one of the secondary tasks that require the operators to selectively read out gauge values while simultaneously ignoring other display elements. The AUTO-CAMS display was supplemented with an integrated display to support information integration implying the cost of deteriorating the focused attention task. In addition, two levels of automation of a model-based fault management reasoning agent were examined. In 70% of the trials this support was reliable. In the remaining trials, difficult double-faults occurred where the agents support became brittle in terms of identifying only one fault correctly, missing fault identification at all because of symptom masking, or giving a false fault identification. Only during brittle trials both PCP predictions could be confirmed: (1) The information integration task of fault identification was improved with the integrated display while the secondary focused attention task performance was deteriorated compared to the support with the non-integrated display. Means to cope with this trade-off problem are discussed.
