title: Using system-wide trust theory to make predictions about dependence on four diagnostic aids.
abstract: System-wide trust strategy can occur when operators are exposed to multiple aids of different reliabilities. D. Keller and S. Rice (2009) showed that when a perfectly reliable aid was presented concurrently with an unreliable aid, participants tended to treat the 2 aids as a unit (system-wide trust) rather than as different units with different reliabilities (component-specific trust). Limitations to their original study prevented the authors from making strong conclusions about a pervasive system-wide trust strategy across domains. The current study revisits this theoretical issue by increasing the number of aids, manipulating the amount of information and feedback participants were given, and using a single-task paradigm rather than a dual-task paradigm. Results were conclusive. While providing information and feedback were beneficial to overall performance, dependence measures indicated that system-wide trust strategies were pervasive across almost all of the manipulations. We discuss the theoretical and applied implications of these data.
