The issues and findings have implications for a wide range of distributed, collaborative work environments, such as military network-enabled operations.

The present research examined the influence of polysemy on word naming. Naming was faster to polysemous than to nonpolysemous words. Moreover, polysemy interacted with word frequency such that the facilitative effects of polysemy were isolated to naming of low-frequency words. These findings are discussed with reference to the distributed models

The present study represents a preliminary examination of the relationship between situation awareness (SA) and confidence within a distributed information-sharing environment using the calibration methodology. The calibration methodology uses the indices of calibration, resolution and over/under-confidence to examine the relationship between the accuracy of the responses and the degree of confidence that one has in these responses, which leads to a measure of an operator's meta-SA. The results of this study revealed that, although the participants were slightly overconfident in their responses, overall they demonstrated good meta-SA. That is, the participants' subjective probability judgements corresponded to their pattern of SA response accuracy. It is concluded that the use of calibration analysis represents a better methodology for expanding our understanding of the relationship between SA and confidence and ultimately how this relationship can impact decision-making and performance in applied settings than can be achieved by examining SA measures alone.

In the present article the calibration of situation awareness and confidence within a multinational coalition was examined. The results revealed differential levels of situational awareness and calibration across the members of the coalition. These findings are discussed in terms of both linguistic and cultural differences within the coalition and the potential implications that poor calibration can have for decision-making and overall team performance.
