Abstract [en]

In this experiment we explore the effects of using a graphical and textual database for

sharing information within a team that are to control a dynamic system. The task involves

fighting a simulated fire. Four people are to co-operate in a layered organisation,

with one layer being the operative and the second layer the supervisory. The operative

layer involves two fire chiefs who are commanding two fire units each. The supervisory

unit consists of two persons that are to co-ordinate the fire chiefs. The supervisory unit

receives all information from the fire chiefs but has to construct an overall picture, a socalled

situation awareness, of the development of the whole area. The supervisory unit

constructs this situation awareness which is meant to be supported by the graphical and

textual databases respectively. We hypothesised that the graphical condition would be

more successful than the textual database in registering the current situation, since the

graphical database allows direct mapping. On the other hand, we hypothesised that the

textual condition might be better in supporting the future planning and prediction of system

dynamics. We analyse 18 quartets, 72 subjects by both performance measures and a

questionnaire. There were no significant performance differences between conditions,

but there is a major learning effect, especially for the textual condition. In accordance

with our hypothesis we found that participants in the graphical condition did better

mapping the map with the ”real” world, at least in the first session. More successful

groups worked more ahead of the fire than did less successful groups. From the questionnaire

it seems that the subjects learn more about co-ordination and trusting their fellow

team members than about the internal dynamics of the simulated fire. In fact, the

teams learn things about system dynamics that are wrong. We therefore suggest that

team SA might be more of a co-ordination problem than a problem of acquiring knowledge

about system dynamics.
