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...

Durch eine hohe Automatisierung ist die Aufgabe von Zugverkehrsleitenden über lange Zeiträume geprägt von typischen monotonierzeugenden Bedingungen. Unklar ist bislang, welche Entstehungsbedingungen wie stark zu der Entstehung von Monotonie beitragen. Offen sind auch die Art und Ausprägung der auftretenden Symptome von Monotonie bei der Aufgabenausführung in der Zugverkehrsleitung. Um Monotonie...

A three-armed cognitive-motor exercise intervention to increase spatial orientation and life-space mobility in nursing home residents: study protocol of a randomized controlled trial in the PROfit project

Wollesen, Bettina ; Fricke, Madeleine ; Jansen, Carl-Philipp ; Gordt, Katharina ; Schwenk, Michael ; Mühlbauer, Thomas ; Morawietz, Christina ; Kruse, Adele ; Gramann, Klaus (2020-10-31)

Background: In nursing home residents, the combination of decreasing mobility and declining cognitive abilities, including spatial orientation, often leads to reduced physical activity (PA) and life-space (LS) mobility. As a consequence of sedentary behavior, there is a lack of social interaction and cognitive stimulation, resulting in low quality of life. It has not yet been examined whether c...

The Role of Frustration in Human–Robot Interaction – What Is Needed for a Successful Collaboration?

Weidemann, Alexandra ; Rußwinkel, Nele (2021-03-22)

To realize a successful and collaborative interaction between human and robots remains a big challenge. Emotional reactions of the user provide crucial information for a successful interaction. These reactions carry key factors to prevent errors and fatal bidirectional misunderstanding. In cases where human–machine interaction does not proceed as expected, negative emotions, like frustration, c...

Driver mental states detection during highly automated driving by decoding brain signals

Zhang, Xixie (2021)

In contrast to manual driving, highly automated driving may relieve the driver from active driving and observing activities. However, undertaking different non-driving tasks while highly automated driving could lead to variations in driver’s mental workload and vigilance levels. This has great influence on driver’s ability and performance to take over control of the vehicle when requested. Ther...

Perceived quality in the automotive industry

Striegel, Serena Simone (2021)

The automotive industry is currently experiencing a volatile market environment. To be successful in this environment, it is essential to retain existing customers and to attract new customers. A comparison of competitor automobiles demonstrates a similarity in technical features. Product features such as design and quality play a decisive role in the success of a company and in convincing cust...

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...

On Kantian tendencies during the early corona pandemic in Germany

Feufel, Markus A. ; Schmid, Christine ; Westfal, Viola (2020-12-23)

Based on an ad hoc online survey about risk perception and preventive behaviours, we describe three chronological phases related to how people in Germany perceived the Corona pandemic between March 22 and May 10, 2020. In general, participants reported to be less concerned about their own risk than about the risk faced by others. However, a good portion of those who thought that they themselves...

Data from a sensorimotor adaptation experiment in virtual reality

Wähnert, Svetlana ; Gerhards, Alexander (2018)

The csv file contains behavioural data from a virtual reality experiment. The aim of the study was to investigate the relationship between the number of interactions and the aftereffect in virtual reality. After a baseline measurement, the virtual environment was displaced visually. During this adaptation phase, the participants performed either zero, five, or thirty-five pointing movements. Af...

Modellierung menschähnlichen Fahrerverhaltens

Kupschick, Stefan (2021)

Fahrermodelle haben in den letzten Jahrzehnten einen bemerkenswerten Fortschritt erlebt. Ausgehend von einfachen technischen Reglern für singuläre Aufgabenstellungen (Längs- bzw. Querregelung) sind sowohl Anforderungen als auch Komplexität stetig gewachsen. Ansätze aus der Psychologie beeinflussen die Fahrermodellentwicklung nachhaltig und führten zur Entwicklung von hybriden Modellen, die Meth...

Towards a conceptual framework for cognitive probing

Krol, Laurens R. ; Zander, Thorsten O. (2018-05-23)

Cognitive probing combines the ability of computers to interpret ongoing measures of arbitrary brain activity, with the ability of those same computers to actively elicit cognitive responses from their users. Purposefully elicited responses can be interpreted in order to learn about the user, enable symbiotic and implicit interaction, and support neuroadaptive technology. We propose a working d...

Towards task-independent workload classification: Shifting from binary to continuous classification

Zhang, Xixie ; Krol, Laurens R. ; Zander, Thorsten O. (2019-01-17)

Passive Brain-Computer-Interfaces provide a promising approach to the continuous measurement of mental workload in realistic scenarios. Typically, a BCI is calibrated to discriminate between different levels of workload induced by a specific task. However, workload in realistic scenarios is typically a result of a mixture of different tasks. Here, we present a study on investigating the possibi...

Salience versus valence in implicit cursor control: First indications of separate cortical processes

Krol, Laurens R. ; Pawlitzki, Juliane ; Mousavi, Mahta ; Andreessen, Lena M. ; Zander, Thorsten O. (2019-11-28)

It has previously been shown that passive brain-computer interfacing enables implicit control over a cursor: participants were able to guide a cursor towards a target without being aware of doing so. The control was based on their brain's automatic responses to the cursor's autonomous movements. This raises questions with respect to informed consent and privacy of thought. The extent to which t...

A task-independent workload classifier for neuroadaptive technology: Preliminary data

Krol, Laurens R. ; Freytag, Sarah-Christin ; Fleck, Markus ; Gramann, Klaus ; Zander, Thorsten O. (2017-02-09)

Passive brain-computer interfacing allows computer systems direct access to aspects of their user's cognition. In essence, a computer system can gain information about its user without this user needing to explicitly communicate it. Based on this information, human-computer interaction can be made more symmetrical, solving an age-old but still fundamental problem of present-day interaction tech...

Automated labeling of movement- related cortical potentials using segmented regression

Rashid, Usman ; Niazi, Imran Khan ; Jochumsen, Mads ; Krol, Laurens R. ; Signal, Nada ; Taylor, Denise (2019-05-07)

The movement-related cortical potential (MRCP) is a brain signal related to planning and execution of motor tasks. From an MRCP, three notable features can be identified: the early Bereitschaftspotential (BP1), the late Bereitschaftspotential (BP2), and the negative peak (PN). These features have been used in past studies to quantify neurophysiological changes in response to motor training. Cur...
