(2019): Trust in socially assistive robots: Considerations for use in rehabilitation. In: Neuroscience & Biobehavioral Reviews 104, S. 231-239. DOI: 10.1016/j.neubiorev.2019.07.014
DOI: https://doi.org/10.1016/j.neubiorev.2019.07.014 Abstract: Incorporation of social robots into rehabilitation calls for understanding what factors affect user motivation and success of the interaction. Trust between the user and the robot has been identified as important in human-robot interaction and in human-human interactions in therapy. Trust has been studied in the context of automation technology, (e.g., autonomous cars), but not in the context of social robots for rehabilitation. In this narrative review, we address the unique patient-clinician-robot triad, and argue that this context calls for specific design features in order to foster trust with the users. We review pertinent methods for measuring trust, and studies demonstrating that culture, prior experience and propensity-to-trust affect to what extent users trust robots. We suggest design guidelines for fostering trust and methods for measuring trust in human-robot interactions in rehabilitation. We stress the need to create measures of trust that are accessible to people who suffer from speech or cognitive impairments. This review is pertinent to researchers, roboticists, and clinicians interested in designing and using social robots for rehabilitation.

(2018) : Readiness for Artificial Intelligence: 2018 IEEE 16th International Symposium on Intelligent Systems and Informatics (SISY): Subotica, Serbia: IEEE, S. 000235-000238
DOI: https://doi.org/10.1109/SISY.2018.8524740 Abstract: In the age of the fourth industrial revolution, where collaborative systems are the real innovation people are still not prepared for the results of the third revolution, namely for artificial intelligence. While every change has its life cycle with innovators, early adopters, early majority before it can reach its fruition, the age of robots has too fast been followed by the internet of things (IoT) of the fourth industrial revolution. Hence, people didn’t have enough time to adapt to the change. In present paper a primary research is presented, that aimed to explore the attitude of young adolescents towards artificial intelligence. Based on the result, trust is clearly one of the main issues regarding change in general and readiness in particular. People are not ready for robotic peers within their workplace yet. Psychological and emotive needs shall be addressed for the people to accept artificial intelligence in their workplace and surrounding.

(2017): How Much to Trust Artificial Intelligence?. In: IT Professional 19 (4), S. 7-11. DOI: 10.1109/MITP.2017.3051326
DOI: https://doi.org/10.1109/MITP.2017.3051326 Abstract: Considerable buzz surrounds artificial intelligence, and, indeed, AI is all around us. As with any software-based technology, it is also prone to vulnerabilities. Here, the author examines how we determine whether AI is sufficiently reliable to do its job and how much we should trust its outcomes.

(2017): Editorial. Trust: The Limits of Human Moral. In: Frontiers in psychology 8. DOI: 10.3389/fpsyg.2017.00178
DOI: https://doi.org/10.3389/fpsyg.2017.00178 Abstract: This editorial briefs the articles featured in this special issue of Frontiers in Psychology . In this special issue on trust, several studies explored how the amount and the type of contact affects trusting behavior. In the course of daily life, people routinely engage in social exchanges that involve some level of trust. Studies published as a part of the current research topic suggest that individuals do not automatically adopt trusting and moral behavior in human interactions, but that those behaviors are determined by and modulated by a plethora of cognitive, psychological, situational, and contextual factors. We believe that research published within the special topic significantly contributes to understanding of trust and we encourage further research both on the brighter and darker sides of trust.

(2017): Communicating intent to develop shared situation awareness and engender trust in human-agent teams. In: COGNITIVE SYSTEMS RESEARCH 46, S. 26-39. DOI: 10.1016/j.cogsys.2017.02.002
DOI: https://doi.org/10.1016/j.cogsys.2017.02.002 Abstract: This paper addresses issues related to integrating autonomy-enabled, intelligent agents into collaborative, human-machine teams. Interaction with intelligent machine agents capable of making independent, goal-directed decisions in human-machine teaming operations constitutes a major change from traditional human-machine interaction involving teleoperation. Communicating the machine agent’s intent to human counterparts becomes increasingly important as independent machine decisions become subject to human trust and mental models. The authors present findings from their research that suggest existing user display technologies, tailored with context-specific information and the human’s knowledge level of the machine agent’s decision process, can mitigate misperceptions of the appropriateness of agent behavioral responses. This is important because misperceptions on the part of human team members increases the likelihood of trust degradation and unnecessary interventions, ultimately leading to disuse of the agent. Examples of possible issues associated with communicating agent intent, as well as potential implications for trust calibration are provided.

(2017): Don’t stare at me: The impact of a humanoid robot’s gaze upon trust during a cooperative human–robot visual task. In: International Journal of Social Robotics 9 (5), S. 745-753. DOI: 10.1007/s12369-017-0422-y
DOI: https://doi.org/10.1007/s12369-017-0422-y Abstract: Gaze is an important tool for social communication. Gaze can influence trust, likability, and compliance. However, excessive gaze in some contexts can signal threat, dominance and aggression, and hence complex social rules govern the appropriate use of gaze. Using a between-subjects design we investigated the impact of three levels of robot gaze (averted, constant and ’situational’) upon participants’ likelihood of trusting a humanoid robot’s opinion in a cooperative visual tracking task. The robot, acting as a confederate, would disagree with participants’ responses on certain trials, and suggest a different answer. As constant, staring gaze between strangers is associated with dominance and threat, and averted gaze is associated with lying, we predicted participants would be most likely to be persuaded by a robot which only gazed during disagreements (’situational gaze’). However, gender effects were found, with females least likely to trust a robot which stared at them, and no significant differences between averted gaze and situational gaze. Implications and future work are discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved)

(2017): Language from police body camera footage shows racial disparities in officer respect. In: Proceedings of the National Academy of Sciences of the United States of America 114 (25), S. 6521-6526. DOI: 10.1073/pnas.1702413114
DOI: https://doi.org/10.1073/pnas.1702413114 Abstract: Using footage from body-worn cameras, we analyze the respectfulness of police officer language toward white and black community members during routine traffic stops. We develop computational linguistic methods that extract levels of respect automatically from transcripts, informed by a thin-slicing study of participant ratings of officer utterances. We find that officers speak with consistently less respect toward black versus white community members, even after controlling for the race of the officer, the severity of the infraction, the location of the stop, and the outcome of the stop. Such disparities in common, everyday interactions between police and the communities they serve have important implications for procedural justice and the building of police-community trust.

(2016): Moral opinion polarization and the erosion of trust. In: Social science research 58, S. 34-45. DOI: 10.1016/j.ssresearch.2016.02.008
DOI: http://www.ncbi.nlm.nih.gov/pubmed/27194650 Abstract: Since Puntam's seminal work on declining levels of social capital, the question of how social trust is formed has reached unprecedented heights of critical enquiry. While most of the current research concentrates on ethnic diversity and income inequality as the main influences driving down generalized trust, we focus on opinion polarization as another potential impact factor on trust. In more detail, we investigate the extent to which polarization over morally charged issues such as homsexuality, abortion and euthanasia affects individuals' likelihood to trust others. We hypothesize that moral issues have a natural tendency to divide societies' opinions into opposing poles and, thus, to challenge social cohesion in modern civil societies. Based on hierarchical analyses of the fifth wave of the World Values Survey (WVS) - comprising a sample of 39 countries - our results reveal that individuals living in countries characterized by more opinion polarization tend to have less trust in other people.

(2015): Gender, trust and cooperation in environmental social dilemmas. In: Social science research 50, S. 328-342. DOI: 10.1016/j.ssresearch.2014.09.002
DOI: http://www.ncbi.nlm.nih.gov/pubmed/25592940 Abstract: This research addresses gender differences in environmental protection efforts. Recent work indicates that, across a variety of domains, women are more generous, charitable, and prosocial than men. Despite above-average levels of these motivators for cooperation, considerable experimental research points to no difference in cooperation between genders. What can explain women's lower-than-expected cooperation levels? Prior research indicates that, compared to men, women are less trusting and respond to fear incentives in social dilemmas - they are concerned about being exploited. We test these arguments in the context of environmental behaviors and argue that lower trust and greater responses to fear incentives mean that women's cooperation is predicated on trust. For men, trust does not predict environmental cooperation. The current research represents the first empirical test of these arguments. Using data from the General Social Survey we focus on private sphere behaviors and political participation and predict an interaction between gender and trust on cooperation. Results support this prediction. zitiert von 12

(2014): Believing on trust. In: Synthese 191 (9), S. 2009-2028. DOI: 10.1007/s11229-013-0376-z
Abstract: The aim of the paper is to propose a way in which believing on trust can ground doxastic justification and knowledge. My focus will be the notion of trust that plays the role depicted by such cases as concerned Hardwig (J Philos 82:335-49, 1985; J Philos 88:693-708, 1991) in his early papers, papers that are often referenced in recent debates in social epistemology. My primary aim is not exegetical, but since it sometimes not so clear what Hardwig's claims are, I offer some remarks of interpretation that might be of interest. The main purpose of the paper, however, is this: following various cues in Hardwig's writing, I specify certain epistemic properties of agents in social systems, such that, roughly speaking, for agents to know (or be justified in believing) what the 'system knows', social relations of epistemic trust between agents in the system are necessary. I will suggest that we can view this social form of epistemic trust as non-inferential dispositions to believe what some individual or other source of information asserts or transmits. When this disposition is discriminating and defeater-sensitive, it can ground knowledge and justification. Or, more cautiously, we should be sympathetic to this view if we are inclined to accept the core insight of process reliabilism. Finally, I will offer some remarks about how epistemic trust and epistemic reasons may relate on this picture.

(2014): Factors influencing trust in Ambient Assisted Living Technology: A scenario-based analysis. In: Gerontechnology 12 (2), S. 81-100. DOI: 10.4017/gt.2013.12.2.002.00
DOI: https://doi.org/10.4017/gt.2013.12.2.002.00 Abstract: Demographic aging in Germany and the related structural change in the health care sector enable a market for assistive technologies for elderly people in a home living environment. The objective of this study is a scenario-based analysis regarding trust in Ambient Assisted Living (AAL). A standardized questionnaire survey with 292 participants from 50 to 93 years of age was conducted in Germany. Two different interview groups, people who need support in daily life due to different kinds of impairment and people without need for care, have been considered. The analysis was using correlation and stepwise regression analysis. As an important finding, a strong relationship between trust in AAL and an intention to use AAL can be highlighted. The significant influencing factors on trust are expected reliability, perceived ease of use, and perceived usefulness of AAL. Information procurement, interest in technology, and perceived health status are further variables which directly influence the end-user intention to use. People with need for care showed lower trust and intention to use values than people without need for care. The analyses show additionally that younger as well as participants with better perceived health status have higher trust values and more intention to use AAL based on the two scenarios. In contrast to a former study in the AAL context, gender has no significant influence on trust. In the future, further experimental studies with focus on elderly persons’ trust in AAL will be performed. These experiments will include, on the one hand, personal remote assistance for the end-user and, on the other hand, variation of actual reliability of AAL technology.

(2012): Virtual project teams. The role of empathy and social intelligence in the development of trust. ProQuest Information & Learning, US.
Abstract: The purpose of this quantitative research study is to determine whether a relationship exist between nine virtual team leaders’ emotional intelligence skills of social intelligence and their empathy practice, and the perceived trust the virtual project team members had for their team leader. The subfactors of social responsibility and interpersonal relationship comprise social intelligence. The study hypothesized that the virtual team leaders’ empathy skills and social skills would positively influence the development of trust, as perceived by the virtual team members. Nine virtual teams from the defense contractor industry in the southeastern United States participated. Two survey instruments were used to evaluate the hypothesis. The Bar-On Emotional Quotient Inventory (EQ-i) survey instrument was used to assess the practiced empathy skills and social intelligence skills if the virtual team leader. The ABC Research Foundation’s Measuring Organizational Trust indicator tool was used to assess the perceived trust of the virtual team members. The results of the study indicated that no significant positive correlation exist between virtual project leaders’ practice of empathic behavior and the development of trust among the team members. Social intelligence, as a whole, is associated with the development of trust in leader-member relationships in virtual project teams. These results further indicated that interpersonal relationship skills are strongly associated with developing positive trust relations and interactions in virtual environments.

(2011): Adaptive aiding of human-robot teaming: Effects of imperfect automation on performance, trust, and workload. In: Journal of Cognitive Engineering and Decision Making 5 (2), S. 209-231. DOI: 10.1177/1555343411410160
DOI: https://doi.org/10.1177/1555343411410160 Abstract: [Correction Notice: An erratum for this article was reported in Vol 5(3) of Journal of Cognitive Engineering and Decision Making (see record [rid]2011-18021-005[/rid]). In the original article, the data in Tables 3 and 4 were switched. The corrected Tables 3 and 4 is given in the erratum.] In many emerging civilian and military operations, human operators are increasingly being tasked to supervise multiple robotic uninhabited vehicles (UVs) with the support of automation. As 100% automation reliability cannot be assured, it is important to understand the effects of automation imperfection on performance. In addition, adaptive aiding may help counter any adverse effects of static (fixed) automation. Using a high-fidelity multi-UV simulation involving both air and ground vehicles, two experiments examined the effects of automation reliability and adaptive automation on human-system performance with different levels of task load. In Experiment 1, participants performed a reconnaissance mission while assisted with an automatic target recognition (ATR) system whose reliability was low, medium, or high. Overall human-robot team performance was higher than with either human or ATR performance alone. In Experiment 2, participants performed a similar reconnaissance mission with no ATR, static automation, or with adaptive automation keyed to task load. Participant trust and self-confidence were higher and workload was lower for adaptive automation compared with the other conditions. The results show that human-robot teams can benefit from imperfect static automation even in high task load conditions and that adaptive automation can provide additional benefits in trust and workload.

(2005): Evolution of indirect reciprocity. In: Nature 437 (7063), S. 1291-1298. DOI: 10.1038/nature04131
DOI: http://www.ncbi.nlm.nih.gov/pubmed/16251955 Abstract: Natural selection is conventionally assumed to favour the strong and selfish who maximize their own resources at the expense of others. But many biological systems, and especially human societies, are organized around altruistic, cooperative interactions. How can natural selection promote unselfish behaviour? Various mechanisms have been proposed, and a rich analysis of indirect reciprocity has recently emerged: I help you and somebody else helps me. The evolution of cooperation by indirect reciprocity leads to reputation building, morality judgement and complex social interactions with ever-increasing cognitive demands.

(2015): Influence of trust in Ambient Assisted Living technologies Humboldt-Universität zu Berlin
DOI: https://doi.org/10.18452/17167 Abstract: Zwischenmenschliches Vertrauen spielt in Beziehungen eine wichtige Rolle und beinhaltet die Erwartung, dass auf das Wort des Anderen Verlass ist (Rotter, 1967). Auch im Zusammenhang mit Automation und Mensch-Maschine-Systemen erlangt die Betrachtung von Vertrauen in den vergangenen Jahren immer größere Bedeutung. In den Bereichen automatisierte Fahrzeugsteuerung oder militärische Freund-Feind-Erkennung wurde bereits eine Vielzahl von Erhebungen durchgeführt. Einen Forschungsgegenstand, der bislang jedoch weitestgehend unbeachtet geblieben ist, stellen Heim-Automatisierungen und Unterstützungstechnologien für ältere Personen dar. Die vorliegende Dissertation möchte einen Anstoß für die Forschungsaktivitäten im Kontext von Vertrauen in Ambient Assisted Living (AAL) Systeme geben und gleichzeitig die Möglichkeiten von Unterstützungs-technologien (für beeinträchtigte Personen) im Wohnumfeld aufzeigen. Im Fokus der Untersuchung steht dabei das Vertrauen älterer Personen, als potentielle Endnutzer, in AAL Systeme. Nach Durchführung der Literaturanalyse, wurden mittels einer Fragebogenstudie zunächst verschiedene Einflussfaktoren auf das Vertrauen in AAL sowie die Nutzungsabsicht der senioren Zielgruppe erforscht. Unter Einbeziehung der Variablen des Technology Acceptance Modells (TAM) (Davis, 1989) werden Personen mit und ohne täglichem Unterstützungsbedarf befragt. Basierend auf den dadurch gewonnenen Erkenntnissen wurden zwei Experimente durchgeführt. Die Probanden der beiden Experimente, die jeweils eine seniore Testgruppe und eine junge Kontrollgruppe umfassten, sollten mittels eines Mock-Ups auf einem Tablet-Computer verschiedene Aufgaben im Wohnumfeld bearbeiten. Im ersten Experiment wurde zusätzlich zu der Standard-Bedienoberfläche der AAL Technologie, entweder persönliche Unterstützung via Operateur oder eine technische Unterstützung zur Verfügung gestellt. Das zweite Experiment untersuchte drei unterschiedliche Stufen von Zuverlässigkeit einer AAL Applikation. Interpersonal trust as “expectancy that the verbal statements of others can be relied upon” (Rotter, 1967; p. 651) plays an important role in human relationships. But even in the context of automation and man-machine systems, the consideration of trust has acquired even greater importance in recent years. In the field of automated vehicle control systems or military friend-or-foe recognition, a large number of surveys relating to trust have been conducted. An area of research that, to date, has not been well-investigated is home automation, such as smart home and assistive technologies for older people. The present thesis aims to initiate such research activities in the context of trust in Ambient Assisted Living (AAL) systems, as well as to demonstrate the opportunities that assistive technologies present for impaired persons in the living environment. The focus of the present survey is on the trust of older people, as potential end-users, in AAL systems. To establish an understanding of the state of this research field, a literature review has been conducted. Subsequently, the various factors influencing trust in AAL and usage intention of the elderly target group are examined via a written questionnaire study. Taking into account the variables of the Technology Acceptance Model (TAM) (Davis, 1989), persons with and without need for daily support are interviewed. Based on the obtained results, two subsequent experiments were carried out. The participants in the two experiments, each including a senior test group and a young control group, worked on various tasks through a mock-up on a tablet-computer in the living environment. In the first experiment, in addition to the standard user interface of the AAL technology, either personal support via operator or a technical embedded support was provided to test the differential impact on the trust of the participants in AAL. The second experiment included three different levels of reliability of an AAL application.
