Complacency and Automation Bias in the Use of Imperfect Automation

چکیده
OBJECTIVE We examine the effects of two different kinds of decision-aiding automation errors on human-automation interaction (HAI), occurring at the first failure following repeated exposure to correctly functioning automation. The two errors are incorrect advice, triggering the automation bias, and missing advice, reflecting complacency. BACKGROUND Contrasts between analogous automation errors in alerting systems, rather than decision aiding, have revealed that alerting false alarms are more problematic to HAI than alerting misses are. Prior research in decision aiding, although contrasting the two aiding errors (incorrect vs. missing), has confounded error expectancy. METHOD Participants performed an environmental process control simulation with and without decision aiding. For those with the aid, automation dependence was created through several trials of perfect aiding performance, and an unexpected automation error was then imposed in which automation was either gone (one group) or wrong (a second group). A control group received no automation support. RESULTS The correct aid supported faster and more accurate diagnosis and lower workload. The aid failure degraded all three variables, but "automation wrong" had a much greater effect on accuracy, reflecting the automation bias, than did "automation gone," reflecting the impact of complacency. Some complacency was manifested for automation gone, by a longer latency and more modest reduction in accuracy. CONCLUSIONS Automation wrong, creating the automation bias, appears to be a more problematic form of automation error than automation gone, reflecting complacency. IMPLICATIONS Decision-aiding automation should indicate its lower degree of confidence in uncertain environments to avoid the automation bias.

OBJECTIVE The aim of this study was to develop and validate a computational model of the automation complacency effect, as operators work on a robotic arm task, supported by three different degrees of automation. BACKGROUND Some computational models of complacency in human-automation interaction exist, but those are formed and validated within the context of fairly simplified monitoring failu...

Experimental Investigation of Relationship between Complacency and Tendency to Use Automation System
In this study, we experimentally investigated the relationship between complacency, defined as missing automation malfunctions, anomalous conditions, or outright failures, and the human tendency to prefer either automation or manual operation. We experimented using two different tasks with human participants to evaluate their individual tendencies to lapse into complacency and to use automation...
متن کاملThe Effects of Age and Working Memory Demands on Automation-Induced Complacency
Complacency refers to a type of automation use expressed as insufficient monitoring and verification of automated functions. Previous studies have attempted to identify the age-related factors that influence complacency during interaction with automation. However, little is known about the role of age-related differences in working memory capacity and its connection to complacent behaviors. The...
