Effects of Trust, Self-Confidence, and Feedback on the Use of Decision Automation

Wiczorek, Rebecca ; Meyer, Joachim (2019-03-12)

Operators often fail to rely sufficiently on alarm systems. This results in a joint human-machine (JHM) sensitivity below the one of the alarm system. The ‘confidence vs. trust hypothesis’ assumes the use of the system depends on the weighting of both values. In case of higher confidence, the task is performed manually, if trust is higher, the user relies on the system. Thus, insufficient relia...

On the Relation Between Reliance and Compliance in an Aided Visual Scanning Task

Wiczorek, Rebecca ; Meyer, Joachim ; Günzler, Torsten (2012)

Alarms, alerts, and other binary cues affect user behavior in complex ways. One relevant distinction is the suggestion that there are two different responses to alerts – compliance (the tendency to perform an action cued by the alert) and reliance (the tendency to refrain from actions as long as no alert is issued). An experiment tested the dependence of the two behaviors on the Positive and Ne...

Benefits of Decision-Support by Likelihood versus Binary Alarm Systems

Wiczorek, Rebecca ; Manzey, Dietrich ; Zirk, Anna (2014)

Recent research has shown that the use of 3-stage likelihood alarm systems (LAS) has the potential to mitigate performance deficits associated with the use of binary alarm systems (BAS). The additional likelihood information can guide operators’ behavior and improve their decision-making accuracy. Comparisons of LAS with different numbers of stages are missing so far. Therefore, the current stu...

Supporting Attention Allocation in Multitask Environments

Wiczorek, Rebecca ; Manzey, Dietrich (2014)

Objective: The aim of the current study was to investigate potential benefits of likelihood alarm systems (LASs) over binary alarm systems (BASs) in a multitask environment. Background: Several problems are associated with the use of BASs, because most of them generate high numbers of false alarms. Operators lose trust in the systems and ignore alarms or cross-check all of them when other info...

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

Wiczorek, Rebecca ; Manzey, Dietrich (2010)

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 purpo...

Human Performance Consequences of Automated Decision Aids in States of Sleep Loss

Reichenbach, Juliane ; Onnasch, Linda ; Manzey, Dietrich (2011)

Objective: The authors investigated how human performance consequences of automated decision aids are affected by the degree of automation and the operator’s functional state. Background: As research has shown, decision aids may not only improve performance but also lead to new sorts of risks. Whereas knowledge exists about the impact of system characteristics (e.g., reliability) on human perf...

Misuse of Automation: The Impact of System Experience on Complacency and Automation Bias in Interaction with Automated Aids

Reichenbach, Juliane ; Onnasch, Linda ; Manzey, Dietrich (2010)

The study investigates how complacency and automation bias effects in interaction with automated aids are moderated by system experience. Participants performed a supervisory control task supported by an aid for fault identification and management. Groups differed with respect to how long they worked with the aid until eventually an automation failure occurred, and whether this failure was the ...

Complacency and Bias in Human Use of Automation: An Attentional Integration

Parasuraman, Raja ; Manzey, Dietrich (2010)

Objective: Our aim was to review empirical studies of complacency and bias in human interaction with automated and decision support systems and provide an integrated theoretical model for their explanation. Background: Automation-related complacency and automation bias have typically been considered separately and independently. Methods: Studies on complacency and automation bias were analyze...

Human Performance Consequences of Stages and Levels of Automation: An Integrated Meta-Analysis

Onnasch, Linda ; Wickens, Christopher D. ; Li, Huiyang ; Manzey, Dietrich (2013)

Objective: We investigated how automation-induced human performance consequences depended on the degree of automation (DOA). Background: Function allocation between human and automation can be represented in terms of the stages and levels taxonomy proposed by Parasuraman, Sheridan, and Wickens. Higher DOAs are achieved both by later stages and higher levels within stages. Method: A meta-analy...

Operators’ Adaption to Unreliability of Alarm Systems: A Performance and Eye-Tracking Analysis

Onnasch, Linda ; Ruff, Stefan ; Manzey, Dietrich (2012)

Operators in complex environments are supported by alarm-systems that indicate when to shift attention to certain tasks. As alarms are not perfectly reliable, operators have to select appropriate strategies of attention allocation in order to compensate for unreliability and maintain overall performance. This study investigates how humans adapt to differing alarm-reliabilities. Within a multi-t...

Measures of Reliance and Compliance in Aided Visual Scanning

Meyer, Joachim ; Wiczorek, Rebecca ; Günzler, Torsten (2013)

Objective: We study the dependence or independence of reliance and compliance as two responses to alarms to understand the mechanisms behind these responses. Background: Alarms, alerts, and other binary cues affect user behavior in complex ways. The suggestion has been made that there are two different responses to alerts—compliance (the tendency to perform an action cued by the alert) and rel...

Human Performance Consequences of Automated Decision Aids

Manzey, Dietrich ; Reichenbach, Juliane ; Onnasch, Linda (2012)

Two experiments are reported that investigate to what extent performance consequences of automated aids are dependent on the distribution of functions between human and automation and on the experience an operator has with an aid. In the first experiment, performance consequences of three automated aids for the support of a supervisory control task were compared. Aids differed in degree of auto...

The present study investigates performance consequences of a new approach of automated support for surgeons. “Navigated-Control” (NC) represents an advancement of image-guided navigation that does not only support the surgeon in navigating through a patient's anatomy, but also can stop the surgical device if it comes too close to risk structures which need to be protected to ensure patient safe...

Asymmetries in Human Tolerance of Uncertainty in Interaction with Alarm Systems: Effects of Risk Perception or Evidence for a General Commission Bias?

Günzler, Torsten ; Manzey, Dietrich (2013)

Providing access towards raw data is often considered to be a good solution for improving human decision making in interaction with imperfect automated decision support such as alarm systems. However, there is some evidence that such cross-checking measures are used in an asymmetric manner with respect to the amount of uncertainty involved in the decision. Namely, people seem to accept low amou...

Enhancing Spatial Orientation in Novice Pilots: Comparing Different Attitude Indicators Using Synthetic Vision Systems

Gross, Alice ; Manzey, Dietrich (2014)
