目的：当前工作的目的是澄清主观信任如何决定响应行为时，与信号system.Background：在多个理论框架，信任被认为是系统错误特性和自动化依赖之间的主要调解人。一些研究者将信任定义为行为表现。其他研究人员认为，虽然信任可能会引导操作员的反应，信任并不完全决定的behavior.Method：44名参与者与一个主要的飞行模拟任务和一个次要的信号系统任务。信号系统的可靠性（90%，60%）和错误偏差（假警报，容易错过）。通过实验会话的时间优先性的标准，在确定信任对behavior.Results：分析表明，信任部分介导的可靠性和协议率之间的关系进行了测量。信任并没有中介可靠性和反应时间之间的关系。信任也没有调解错误偏差和反应时间或协议率之间的关系。方差分析普遍支持特定的行为和信任假设，表明所采用的范式产生了类似的影响反应行为和主观估计的信任在其他study.Conclusion：这些结果表明，强假设的信任作为主中介系统错误的特点和反应行为应谨慎看待。从业者应考虑评估信任以外的因素，以确定潜在的操作员响应行为，这可能更具预测性。
Objective: The purpose of the current work was to clarify how subjective trust determines response behavior when interacting with a signaling system.Background: In multiple theoretical frameworks, trust is acknowledged as a prime mediator between system error characteristics and automation dependence. Some researchers have operationally defined trust as the behavior exhibited. Other researchers have suggested that although trust may guide operator responses, trust does not completely determine the behavior.Method: Forty-four participants interacted with a primary flight simulation task and a secondary signaling system task. The signaling system varied in reliability (90%, 60%) and error bias (false alarm, miss prone). Trust was measured halfway through the experimental session to address the criterion of temporal precedence in determining the effect of trust on behavior.Results: Analyses indicated that trust partially mediated the relationship between reliability and agreement rate. Trust did not mediate the relationship between reliability and reaction time. Trust also did not mediate the relationships between error bias and reaction time or agreement rate. Analyses of variance generally supported specific behavioral and trust hypotheses, indicating that the paradigm employed produced similar effects on response behaviors and subjective estimates of trust observed in other studies.Conclusion: These results indicate that strong assumptions of trust acting as the prime mediator between system error characteristics and response behaviors should be viewed with caution.Application: Practitioners should consider assessing factors other than trust to determine potential operator response behaviors, which may be more predictive.
