Is Operators' Compliance with Alarm Systems a Product of Rational Consideration?

Wiczorek, Rebecca; Manzey, Dietrich

Most theories about operators' responses to alarm systems suggest that the operators' behavior is guided by their trust towards the system which in turn results from the subjective perception of system properties, namely the perceived reliability of the alarm system. However, some doubts about that assumption have arisen as recent research has not proven the mediating effect of trust. The purpose of this research was to examine the relationship between alarm system properties, trust, and behavior. The alarm reliability was varied while keeping the other system properties constant. It was found that participants' response-rates to alarms were predicted by their perceived alarm reliabilities. However, no mediation by trust could be established. These results suggest that operators' behavior is not always guided by their trust towards the system. Under specific circumstances their compliance rather depends on rational consideration regarding the most efficient strategy.
