The more the better? The impact of number of stages of likelihood alarm systems on human performance

Balaud, Magali ; Manzey, Dietrich (2015)

Responses to alarms involve decisions under uncertainty. Operators do not know if an alarm is more likely to be a hit or a false alarm. Likelihood alarm systems (LAS) help reduce this uncertainty by providing information about the certainty of their output. Unlike traditional binary alarm systems, they have three or more stages: each one represents a different degree of likelihood that a critic...

Decision-making and response strategies in interaction with alarms: the impact of alarm reliability, availability of alarm validity information and workload

Manzey, Dietrich ; Gérard, Nina ; Wiczorek, Rebecca (2014-09-16)

Responding to alarm systems which usually commit a number of false alarms and/or misses involves decision-making under uncertainty. Four laboratory experiments including a total of n=256 participants were conducted to gain comprehensive insight into humans’ dealing with this uncertainty. Specifically, it was investigated how responses to alarms/nonalarms are affected by the predictive validitie...

Do we really need more stages? Comparing the effects of likelihood alarm systems and binary alarm systems

Zirk, Anna ; Wiczorek, Rebecca ; Manzey, Dietrich (2019-06-19)

Objective: This research investigates the potential behavioral and performance benefits of a 4-stage likelihood alarm system (4-LAS) contrasting a 3-LAS, a binary alarm system with a liberal threshold (lib-BAS) and a BAS with a conservative threshold (con-BAS). Background: Prior research has shown performance benefits of 3-LASs over conventional lib-BASs due to more distinct response strategie...

Toward a framework for selecting behavioural policies: How to choose between boosts and nudges

Grüne-Yanoff, Till ; Marchionni, Caterina ; Feufel, Markus A. (2018-04-26)

In this paper, we analyse the difference between two types of behavioural policies – nudges and boosts. We distinguish them on the basis of the mechanisms through which they are expected to operate and identify the contextual conditions that are necessary for each policy to be successful. Our framework helps judging which type of policy is more likely to bring about the intended behavioural out...

Trust in highly automated driving

Stephan, Amelie (2019)

The automotive industry is on the verge of a new technology: self-driving vehicles. Such highly automated driving vehicles are more and more technically feasible, and corporations and research institutes all over the world are investing time and money to bring the once futuristic vision on the road. The technology is developed with the goal to release the driver from the manual task of controll...

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...

ACT-R model for: A Cognitive Modeling Approach to Strategy Formation in Dynamic Decision Making

Sabine, Prezenski (2018-01)

This ACT-R model complements the publications "A Cognitive Modeling Approach to Strategy Formation in Dynamic Decision Making" and "Implementing Mental Model Updating in ACT-R". The model uses an exemplar-based and a rule-based Approach and meta-cognitive aspects. The model solves and auditoy categorization task.

Interactive learning of dynamic systems

Prezenski, Sabine (2019)

People who want to achieve a goal with a previously unknown technical system simply try it out and learn through feedback from the system how to use it. This is referred to as interactive Learning. To investigate the usability of such systems, elaborate user studies are carried out. Additionally, changes in the system require new studies. Cognitive models simulate the cognitive processes of use...

Full shift usage of smart glasses in order picking processes considering a methodical approach of continuous user involvement

Murauer, Cornelia Sophie (2019)

Smart factories, in which processes are partially or completely automated and digitalized, are the future. Automobile production is also currently undergoing said change towards ‘Industry 4.0’. While the degree of automation is very high in car body construction due to the use of robots, the degree of automation in logistics varies depending on the process. By contrast, in transportation proces...

Aufmerksamkeitsfokus beim Bewegungslernen

Wähnert, Svetlana (2019)

Bei Bewegungsaufgaben mit Lernbedarf, scheint der Fokus auf den Umwelteffekt (externer Aufmerksamkeitsfokus) zu anderen Lernergebnissen zu führen als der Fokus auf den eigenen Körper (interner Aufmerksamkeitsfokus). Viele Studien konnten dabei eine Überlegenheit des externen Aufmerksamkeitsfokus aufzeigen. Die vorliegende Forschungsarbeit beinhaltet sowohl einen Grundlagen- als auch einen Anwen...

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...

The state and perspective of developmental psychology in the Federal Republic of Germany is analyzed with respect to (a) professional education, (b) resources for research, (c) actual fields of research, and (d) media of professional communication. Current trends of research were investigated by a combination of multi-category content analyses of national (and international) journal publication...

Maturational Timing and the Development of Problem Behavior

Silbereisen, Rainer K. ; Petersen, Anne C. ; Albrecht, Helfried T. ; Kracke, Bärbel (1989)

Previous research demonstrated a higher risk for problem behaviors among early as compared to late maturing girls. In the present study, the role of maturational timing was assessed within the framework of a developmental model for adolescent problem behavior. Data obtained twice, one year apart, on 62 girls in early adolescence (11 to 12 years of age) and 193 girls in middle adolescence (14 to...

Trust in high-reliability organizations

Schöbel, Markus (2009)

The present article aims to highlight the effects of trust on safety performance in high-reliability organizations (HROs) like nuclear power plants, chemical plants or hospital emergency departments. The author claims that not only beneficial but also detrimental effects have to be considered in the analysis of trust within these socio-technical systems. Potential safety outcomes of trusting be...
