Abstract This review article discusses the influence of stress on high-level cognitive procedures such as judgment and decision-making in the context of risk assessment. It focuses on the impact of stress in the work environment on risk-taking when complex technical systems have to be implemented. Analysis of recent findings suggests that stress generates poor-quality data processing operations for activities designated as complex in cognitive psychology terms. Stress is a contributory cause of bias in assessment procedures, because it affects all stages involved in obtaining appropriate estimates of risk. Narrowing the perceptual field affects data selection and diminishes the range of indicators taken into account; narrowing the cognitive field modifies the optimum weighting that would normally apply to these factors. In addition, stress accelerates the adoption of simplified strategies that encourage the use of often contradictory localized rationales, to the detriment of more broad-based ones that would enable a wider view to be taken. Examination of these findings leads to the conclusion that it is the diversity and creativeness of cognitive resources that are most affected by stress. On the basis of experimental findings, a neuro-psychological hypothesis involving interconnecting networks is proposed.
