Diagnostic automation is frequently used to assist pilots. Despite extensive research on trust in automation, multiple automation research is sparse. Two recent studies focused on effects of trust in multiple automation using system-wide trust (SWT) theory (Keller & Rice, 2010; Rice & Geels, 2010). According to SWT, operators treat multiple aids as one entity, rather than separate entities; an unreliable aid negatively affects trust in nearby aids. We combined SWT with Meyer’s (2001, 2004) compliance-reliance model in order to show whether contagion effects of FAs and misses differ. Participants monitored 8 gauges for system failures. Each gauge had an automated aid that provided recommendations. The first aid was 70% reliable, and produced either FAs or misses, while the other 7 aids were 100% reliable. The data indicate that both FAs and misses cause contagion on the perfectly reliable aids, but FAs caused more contagion in both compliance and reliance measures.
