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...

Visual search behavior and performance in luggage screening: effects of time pressure, automation aid, and target expectancy

Rieger, Tobias ; Heilmann, Lydia ; Manzey, Dietrich (2021-02-25)

Visual inspection of luggage using X-ray technology at airports is a time-sensitive task that is often supported by automated systems to increase performance and reduce workload. The present study evaluated how time pressure and automation support influence visual search behavior and performance in a simulated luggage screening task. Moreover, we also investigated how target expectancy (i.e., t...

Individuelle Bearbeitungspräferenzen beim Multitasking

Reissland, Jessika (2021)

Concurrent multitasking will often be a challenge for human information processing. Dealing with that, several tasks that are visible at the same time could be processed either in a rather separated or in a rather integrated or even parallel manner. Only a few studies have investigated individual strategies when working in a concurrent multitasking situation so far, although some evidence clear...

Multitasking strategies make the difference: Separating processing-code resources boosts multitasking efficiency when individuals prefer to interleave tasks in free concurrent dual tasking

Brüning, Jovita ; Mückstein, Marie ; Manzey, Dietrich (2020)

Previous research has shown that individuals differ with respect to their preferred strategies in self-organized multitasking: They either prefer to work on one task for long sequences before switching to another (blocking), prefer to switch repeatedly after short sequences (switching), or prefer to respond almost simultaneously after processing the stimuli of two concurrently visible tasks (re...

Motivierende Leitstandgestaltung: Unterstützung von Überwachungstätigkeiten durch Gamification

Spahrbier, Mali (2020)

In der Automobilproduktion nehmen durch den steigenden Automatisierungsgrad und die Digitalisierung überwachende Tätigkeiten von Produktionsanlagen in Leitständen zu. Die Überwachungstätigkeit ist mental und psychisch hoch beanspruchend (Warm, Parasuraman, & Matthews, 2008). Gleichzeitig bietet die Überwachungstätigkeit durch den passiven Charakter wenige Möglichkeiten zur Befriedigung psychisc...

Flexibility and efficiency of individual preferences for task coordination strategies in multitasking

Brüning, Jovita (2020)

In our rapidly changing world, we are often juggling several task demands at once, and in doing so we constantly need to adapt to changing task requirements. To date, a plethora of studies addressed the question to which degree humans can perform two or more tasks in a concurrent or sequential manner. Notably, most of these studies disregarded that people might differ considerably in their indi...

Individual preferences for task coordination strategies in multitasking: exploring the link between preferred modes of processing and strategies of response organization

Brüning, Jovita ; Reissland, Jessika ; Manzey, Dietrich (2020-01-31)

Recent investigation of individual differences in multitasking revealed evidence for individual preferences for modes of task processing (serial vs. overlapping) in a task switching with preview (TSWP) paradigm and different strategies of response organization (blocking, switching, and response grouping) in a free concurrent dual-tasking (FCDT) paradigm. However, this research on individual dif...

Disentangling stimulus and response compatibility as potential sources of backward crosstalk

Rieger, Tobias ; Miller, Jeff (2020-06-11)

In two experiments (N= 60 each), we investigated the locus of backward crosstalk effects in dual tasking. Specifically, we embedded the typical flanker task within a dual-task paradigm by assigning stimulus-response (S-R) rules to the flankers. In Experiment 1, participants were instructed to first respond to the center letter and only respond to the flanker if the center was a no-go stimulus (...

Attitude indicator format

Müller, Simon ; Roche, Fabienne ; Manzey, Dietrich (2019-10-15)

Abstract. A simulator study investigated the consequences of a transition between two alternative formats of the attitude indictor in aircraft cockpits, the moving-horizon and moving-aircraft format. Two groups of novices practiced performing two flight tasks (flight-path tracking and recovery from unusual attitudes) with one attitude-indicator format for six practice sessions, before transitio...

Humans and automated decision aids: A match made in heaven?

Mosier, Kathleen L. ; Manzey, Dietrich (2019-09-19)

This chapter particularly focuses on the performance consequences of decision support systems (DSSs) with a particular emphasis on the issue of automation bias as demonstrated in research across many domains. We examine the factors that impact automation bias including operator characteristics such as trust in the system, level of perceived accountability, system characteristics such as reliabi...

Moving-horizon versus moving-aircraft: Effectiveness of competing attitude indicator formats on recoveries from discrete and continuous attitude changes

Müller, Simon ; Korff, Christian ; Manzey, Dietrich (2020)

The present research revisits the old issue whether attitude information is best conveyed to pilots in a moving-horizon format or in a moving-aircraft format. Previous research has suggested that the moving-aircraft format might not be beneficial for flight path tracking but recoveries from unusual attitudes, although the result are not fully consistent. A limitation of studies to date is that ...

‘Hey robot, please step back!’ - exploration of a spatial threshold of comfort for human-mechanoid spatial interaction in a hallway scenario

Lauckner, M. ; Kobiela, F. ; Manzey, Dietrich (2014-10-20)

Within the scope of the current research the goal was to develop an autonomous transport assistant for hospitals. As a sort of social robots, they need to fulfill two main requirements with respect to their interactive behavior with humans: (1) a high level of safety and (2) a behavior that is perceived as socially proper. One important element includes the characteristics of movement. However,...

Operators׳ adaptation to imperfect automation – Impact of miss-prone alarm systems on attention allocation and performance

Onnasch, Linda ; Ruff, Stefan ; Manzey, Dietrich (2014-05-13)

Operators in complex environments are often 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 to compensate for unreliability and to maintain overall performance. This study explores how humans adapt to differing alarm reliabilities. Within a multi-task ...

Impact of image-guided surgery on surgeons' performance: a literature review

Luz, Maria ; Strauss, Gero ; Manzey, Dietrich (2017-04-08)

he goal of current work is to provide a literature review of the performance consequences of image-guided surgery (IGS) use. Regarding IGS system functionalities, the pattern of results suggests to distinguish between IGS systems which only provide information support (e.g. pointer-based systems) and those which directly intervene in surgeons' decision-making and actions (e.g. instrument disabl...

Serial or overlapping processing in multitasking as individual preference: Effects of stimulus preview on task switching and concurrent dual-task performance

Reissland, Jessika ; Manzey, Dietrich (2016-05-05)

Understanding the mechanisms and performance consequences of multitasking has long been in focus of scientific interest, but has been investigated by three research lines more or less isolated from each other. Studies in the fields of the psychological refractory period, task switching, and interruptions have scored with a high experimental control, but usually do not give participants many deg...

This article describes the development, application and validation of a safety culture assessment approach for nuclear power plants based on Schein's culture model. The developed multi-method approach aimed to unfold deeper levels of culture, and, at the same time, to be applicable by practitioners and transparent in producing meaningful results. In Study 1 we describe the development of the me...

Cognitive and psychomotor performance

Manzey, Dietrich (2017-10-25)

During space flight, astronauts are exposed to a variety of stressors. Some of these stressors originate from the specific environmental conditions in space (e.g. microgravity, radiation). Others are more unspecific and originate from living and working as member of a small crew in a confined and isolated habitat (e.g. lack of privacy, social monotony). This chapter summarizes our current knowl...

Flexibility of individual multitasking strategies in task-switching with preview: are preferences for serial versus overlapping task processing dependent on between-task conflict?

Brüning, Jovita ; Manzey, Dietrich (2017-10-05)

The prevalence and the efficiency of serial and parallel processing under multiple task demands are highly debated. In the present study, we investigated whether individual preferences for serial or overlapping (parallel) processing represent a permanent predisposition or depend on the risk of crosstalk between tasks. Two groups (n = 91) of participants were tested. One group performed a classi...
