| Summary: | We examined the influence of experience upon information-sampling and decision-making behaviour in a group of military personnel as they conducted risk assessments of scenes photographed from patrol routes during the recent conflict in Afghanistan. Their risk assessment was based on an evaluation of Potential Risk Indicators during examination of each scene. We found that both participant groups were equally likely to fixate Potential Risk Indicators, demonstrating similarity in the selectivity of their information-sampling. However, the inexperienced participants made more revisits to Potential Risk Indicators, had longer response times, and were more likely to decide that the scenes contained a high level of risk. Together, these results suggest that experience primarily modulates decision-making behaviour. We discuss potential routes to train personnel to conduct risk assessments in a more similar manner to experienced participants.
