Abstract : This research was concerned with ways in which a C3-system adapts to the breakdown of a decision aiding device (DAD). Subjects were tested in a team judgement task in which they had to predict the outcome of an uncertain, dynamic event on discrete trails, with or without the use of a DAD of varying validity. After training, DAD validity was reduced to zero. Subjects performed more poorly with a DAD of low validity than without a DAD. Subjects consistently performed more poorly than they could have by using a maximizing strategy. After DAD breakdown, subjects performed more poorly than control subjects who never used a DAD. Prior DAD validity had no effect on performance with an invalid DAD. Performance with an invalid DAD was found to be predicted by efficiency, the ability to use valid and ignore invalid information.
