Fixation error is defined as the failure to revise a situation assessment as new evidence comes in. A case of fixation error coming from industry is briefly presented and analysed within the conceptual framework provided by COSIMO, a computer-based model of an operator's cognitive processes, developed at the Joint Research Centre, Ispra. Hypotheses about cognitive mechanisms that play a role in such error patterns can be formally expressed in this environment. COSIMO can be used as a symbolic field of experimentation. The circumstances under which the program does or does not fixate can be compared to empirical data on human problem solving performance, leading to suitable safety recommendations.
