The extensive use of advanced automated systems has created new concern for
automation- induced complacency which is defined as inability to detect an
automation malfunction. The present experiment examined the ef fects of
automation training, automation reliability and workload on automation- induced
complacency. 120 non-pilot s participants operated a flight simulation t ask with
several windows in which they have to detect automation malfunctions. The NASATLX was administered for the assessment of ment al workload. A 2(training) x
3(reliability) x 2(session) x 3(block) mixed factorial design was used. Participants
received either 30 min of short or 60 min of long automation training on low/mod/
high automation reliability conditions, besides a common practice of 10 min on
manual mode. Performances were recorded in terms of hits, false alarms and
reaction time on system monitoring task and as root mean s quare errors on the
tracking and on the fuel resource management tasks. Results showed that high
static automation reliability increased automation-induced complacency and
perceived mental workload reduced from pre- to post test sessions under high
static reliability condition
