OBJECTIVE This article aims to explore the nature and resolution of breakdowns in coordinated decision making in distributed safety-critical systems. BACKGROUND In safety-critical domains, people with different roles and responsibilities often must work together to make coordinated decisions while geographically distributed. Although there is likely to be(More)
OBJECTIVE The presence of social psychological pressures on pilot decision making was assessed using qualitative analyses of critical incident interviews. BACKGROUND Social psychological phenomena have long been known to influence attitudes and behavior but have not been highlighted in accident investigation models. METHOD Using a critical incident(More)
To meet an identified gap in the literature this paper investigates the tasks that a volunteer incident commander needs to carry out during an incident, the errors that can be made and the way that errors are managed. In addition, pressure from goal seduction and situation aversion were also examined. Volunteer incident commanders participated in a two-part(More)
Task analysis is an important tool that enables designers to consider the human factors implications of a new technology. This paper details a task analysis for the task of driving long-haul freight trains in Australia and describes how this task analysis was used to evaluate a new in-cab information support technology. This paper then explores similarities(More)
Four experiments explored effects on analogical transfer of evaluating solutions to base problems. In contrast to reports of positive effects of explanation, evaluation consistently reduced transfer rates and impaired mental representations of base material. This effect was not ameliorated by encoding for a later memory test, summarizing, or engaging in(More)
Evaluation is generally considered to enhance problem solving and is strongly correlated with increasing expertise. Moreover, manipulations that increase the active processing of source problems generally promote analogical transfer of solution principles. Therefore, we expected that an instruction to evaluate the information given in problem and solution(More)
Despite the postulated importance of analogising to human cognition, the study of analogical problem solving in the laboratory has found disappointing results. Providing an analogue to a participant prior to asking them to solve a problem gives only a small benefit at best. Recently, studies outside the laboratory have suggested that experts frequently use(More)
