(2017): Elaborating time in space. The structure and function of space-motion metaphors of time. In: LANGUAGE AND COGNITION 9 (2), S. 191-253
Abstract: This paper studies the principles according to which spatial and motion concepts metaphorically structure temporal concepts in some languages. There are two types of space–motion metaphor of time, distinguished by whether or not the metaphor is structured by a person’s perspective. “Christmas is approaching” and “We are approaching Christmas” are perspectival. “New Year’s follows Christmas” is not. This contrast in deixis and frame of reference is linguistically relevant whether the contrast has to do with imagination or external reality. Study of experiential motivations and analysis into primary metaphors helps reveal the particular ways spatial and motion concepts function in each type of metaphor. One focus is accounting for the contrasting temporal meanings that words for in-front and behind can have. For example, “Ahead of us” is later than Now, while “ahead of Christmas” is earlier than Christmas. We find that the temporal ‘directions’ expressed in the contrasting frames of reference are not opposites. Rather, they are motivated by different kinds of temporal experience. This project investigates the fundamental spatial relations that structure temporal concepts; for example co-location vs. separation. But since motion involves time, purely spatial structure is limited. Conceptual blending analysis reveals that the source and target frames of the perspectival metaphors share an aspectual – i.e., temporal – generic structure. Thus a dichotomy between ‘space’ and ‘time’ is of limited utility in describing space–motion metaphors of time. Instead, the analysis has to deal with the specific spatial and temporal concepts that function in each metaphor.

(2017): "You Need to Be a Good Listener". Recruiters' Use of Relational Communication Behaviors to Enhance Clinical Trial and Research Study Accrual. In: Journal of health communication 22 (2), S. 95-101. DOI: 10.1080/10810730.2016.1256356
DOI: http://www.ncbi.nlm.nih.gov/pubmed/28085636 Abstract: Medical and research professionals who discuss clinical trials and research studies with potential participants face an often daunting challenge, particularly when recruiting from minority and underserved populations. This study reports on findings from a focus group study of 63 research coordinators, study nurses, professional recruiters, and other professionals in Indianapolis, IN and Miami, FL who work to recruit from minority and underserved populations. These professionals discussed the importance of creating a sense of connection with potential participants as part of the recruitment and retention process. Building a relationship, however fleeting, involved a number of concrete behaviors, including listening to personal information, expressing empathy, and then providing reciprocal self-disclosures; having repeated contact, usually by working in the same environment over an extended period of time; demonstrating respect through politeness and the use of honorifics; going the extra mile for participants; offering flexibility in scheduling follow-up appointments; and creating a sense of personal and community trust by being truthful. The implications of these findings for clinical trial and research study accrual are discussed.

(2017): An experimental investigation into perceptions of disrespect during interpersonal conflict. In: Social science research 62, S. 134-149. DOI: 10.1016/j.ssresearch.2016.08.001
DOI: http://www.ncbi.nlm.nih.gov/pubmed/28126094 Abstract: Perceptions of disrespect are central to everyday life. Despite the importance of disrespect across various social arenas, prior research has failed to empirically examine the factors influencing these perceptions. This problem is magnified when considering that perceptions or disrespect may vary across individuals and social situations alike. Drawing from theories of social geometry and symbolic interaction, this study examines the individual and situational characteristics that inform perceptions of disrespect. Using factorial vignettes, and a large sample of students, respondents were asked to assess actors in various conflicts. Results from a series of hierarchical linear models show that perceptions of disrespect vary across individuals. The content of situations appears to drive perceptions of disrespect more than individual characteristics. Implications for future research on disrespect are discussed.

(2017): News Values, Cognitive Biases, and Partisan Incivility in Comment Sections. In: Journal of Communication 67 (4), S. 586-609. DOI: 10.1111/jcom.12312
Abstract: Partisan incivility is prevalent in news comments, but we have limited insight into how journalists and news users engage with it. Gatekeeping, cognitive bias, and social identity theories suggest that journalists may tolerate incivility while users actively promote partisan incivility. Using 9.6 million comments from The New York Times, we analyze whether the presence of uncivil and partisan terms affects how journalists and news users engage with comments. Results show that partisanship and incivility increase recommendations and the likelihood of receiving an abuse flag. Swearing increases the likelihood of a comment being rejected and reduces the chances of being highlighted as a NYT Pick. These findings suggest that journalists and news users interact with partisan incivility differently, and that some forms of incivility may be promoted or tacitly accepted in comments.

(2017) : Cross-cultural differences for adaptive strategies of robots in public spaces: 2017 26th IEEE International Symposium on Robot and Human Interactive Communication (RO-MAN): Lisbon, Portugal: IEEE Robotics & Automation Society, S. 573-578
DOI: https://doi.org/10.1109/ROMAN.2017.8172360 Abstract: Robots deployed in public spaces must necessarily deal with situations that demand them to engage humans in a socially and culturally appropriate manner. However, social environments are often complex and ambiguous: many queries to the robot are collaborative (e.g. a family), and in case of conflicting queries, social robots need to participate in value decisions and negotiating multi-party interactions. Given the strong influence of the people’s demographic information and social schema among people, such as relationships and hierarchies, the focus of this research is to examine whether and how people exhibit socio-psychological effects with a shared robot deployed at international events or spaces (e.g. airports). With the aim to investigate who robots should adapt to (children or adults) in multi-party situations within human-robot interactions in public spaces and whether this adaptation can be influenced by culture, this paper presents a cross-cultural study conducted online. The results include a number of interesting findings based on people’s relationship with a child and their parental status. In addition, a number of cross-cultural differences were identified in respondents’ attitude towards robot’s multi-party adaptation in various public settings.

(2017): Human–machine interaction theories and lane departure warnings. In: Theoretical Issues in Ergonomics Science 18 (6), S. 519-547. DOI: 10.1080/1463922X.2016.1243274
DOI: https://doi.org/10.1080/1463922X.2016.1243274 Abstract: A technological race toward always ever-increasing automation is engaged, a race in which automation users are hardly considered. This explains why more automation is not necessarily for the best. A variety of human–machine interaction (HMI) theories co-exist. First, those HMI theories and predictions for lane departure warnings systems (LDWS, assisted driving automation) are described. Second, a synthesis of the key questions currently addressed by empirical data on LDWS is offered. Lastly, a new model of human–machine cooperation modelling is proposed. The model has been inspired by previous theories and empirical data collected with LDWS-assisted driving. Interestingly, automation such as LDWS seems to avoid the ‘ironies of automation’ with no negative effects on human performance. However, a major issue to be addressed is poor automation acceptance. While the focus was set on LDWS to offer a complete overview for this type of device, the model may be extended to other warning assistance devices.

(2017): Kultursensible Aspekte während der Diagnostik von psychischen Belastungen bei Flüchtlingen – Zwei kommentierte Fallberichte. In: Psychotherapie, Psychosomatik, medizinische Psychologie 67 (3-04), S. 109-118. DOI: 10.1055/s-0042-107802
DOI: http://www.ncbi.nlm.nih.gov/pubmed/27706544 Abstract: High levels of mental disorders, especially PTSD, are commonly known among groups of people forced to leave their homeland as a consequence of war-related experiences (e. g. armed conflict, torture or persecution). Depending on the cultural background the perceptions of illnesses vary, different symptom presentation and thereupon different coping strategies respectively expectations towards health care services exist. To minimize the danger of misdiagnosis by different experts working with refugees in the host countries, a culture-sensitive diagnostic approach is needed from the beginning. This article describes important aspects of culture-sensitive diagnostics by means of 2 commented case reports. Special focus is set on the aspect of linguistic and in a broader sense cultural comprehension between therapist, client and if necessary language mediator.

(2017): Philosophy of games. In: Philosophy Compass 12 (8). DOI: 10.1111/phc3.12426
Abstract: What is a game? What are we doing when we play a game? What is the value of playing games? Several different philosophical subdisciplines have attempted to answer these questions using very distinctive frameworks. Some have approached games as something like a text, deploying theoretical frameworks from the study of narrative, fiction, and rhetoric to interrogate games for their representational content. Others have approached games as artworks and asked questions about the authorship of games, about the ontology of the work and its performance. Yet others, from the philosophy of sport, have focused on normative issues of fairness, rule application, and competition. The primary purpose of this article is to provide an overview of several different philosophical approaches to games and, hopefully, demonstrate the relevance and value of the different approaches to each other. Early academic attempts to cope with games tried to treat games as a subtype of narrative and to interpret games exactly as one might interpret a static, linear narrative. A faction of game studies, self-described as ludologists, argued that games were a substantially novel form and could not be treated with traditional tools for narrative analysis. In traditional narrative, an audience is told and interprets the story, where in a game, the player enacts and creates the story. Since that early debate, theorists have attempted to offer more nuanced accounts of how games might achieve similar ends to more traditional texts. For example, games might be seen as a novel type of fiction, which uses interactive techniques to achieve immersion in a fictional world. Alternately, games might be seen as a new way to represent causal systems, and so a new way to criticize social and political entities. Work from contemporary analytic philosophy of art has, on the other hand, asked questions whether games could be artworks and, if so, what kind. Much of this debate has concerned the precise nature of the artwork, and the relationship between the artist and the audience. Some have claimed that the audience is a cocreator of the artwork, and so games are a uniquely unfinished and cooperative art form. Others have claimed that, instead, the audience does not help create the artwork; rather, interacting with the artwork is how an audience member appreciates the artist's finished production. Other streams of work have focused less on the game as a text or work, and more on game play as a kind of activity. One common view is that game play occurs in a magic circle. Inside the magic circle, players take on new roles, follow different rules, and actions have different meanings. Actions inside the magic circle do not have their usual consequences for the rest of life. Enemies of the magic circle view have claimed that the view ignores the deep integration of game life from ordinary life and point to gambling, gold farming, and the status effects of sports. Philosophers of sport, on the other hand, have approached games with an entirely different framework. This has lead into investigations about the normative nature of gameswhat guides the applications of rules and how those rules might be applied, interpreted, or even changed. Furthermore, they have investigated games as social practices and as forms of life.

(2017): A Dual-Identity Model of Responses to Deviance in Online Groups. Integrating Social Identity Theory and Expectancy Violations Theory. In: Communication Theory 27 (3), S. 243-268. DOI: 10.1111/comt.12113
Abstract: Several theories have sought to address responses to normatively deviant behavior, but have done so with a focus either on group‐level or on individual‐level behavior. Yet, due to some characteristics of online contexts, identities can be salient at both a group and/or individual level, creating a more complex set of influences on responding to deviance. We explore responses to online communicative deviance by integrating social identity approaches (a group‐level perspective) and expectancy violations theory (an individual‐level perspective). Social identity emphasizes the role of group identification in responding to deviance, especially relevant in anonymous online contexts, while expectancy violations theory notes how individuals respond to ambiguous deviance through assessing the reward value of the deviant.

(2017) : Social norms and their enforcement In: Harkins, Stephen G.; Williams, Kipling D.; Burger, Jerry M. (Hg.): The Oxford handbook of social influence: New York: Oxford University Press (Oxford library of psychology), S. 147-164
Abstract: In this chapter social norms are redefined as 'rules and standards that are understood by members of a group, and that guide morally relevant social behavior by way of social sanctions, instead of the force of laws.' In line with this revised definition, the chapter includes a discussion of how and when individuals enforce social norms along with the customary review of the literature on social norms as agents of social influence. A discussion of how to maximize the impact of social norms interventions follows with special consideration given to (a) combining descriptive and injunctive norms, (b) reference groups, (c) personal relevance, and (d) cognitive resources. The chapter also includes a discussion of the tendency to underestimate the influence of social norms, both on one's own behavior and the behavior of others. Several conflicting results are identified and suggestions are made for how to resolve them with future research.

(2017): Culture-specific models of negotiation for virtual characters. Multi-attribute decision-making based on culture-specific values. In: AI & Society 32 (1), S. 51-63. DOI: 10.1007/s00146-014-0570-7
Abstract: We posit that observed differences in negotiation performance across cultures can be explained by participants trying to optimize across multiple values, where the relative importance of values differs across cultures. We look at two ways for specifying weights on values for different cultures: one in which the weights of the model are hand-crafted, based on intuition interpreting Hofstede dimensions for the cultures, and one in which the weights of the model are learned from data using inverse reinforcement learning (IRL). We apply this model to the Ultimatum Game and integrate it into a virtual human dialog system. We show that weights learned from IRL surpass both a weak baseline with random weights and a strong baseline considering only one factor for maximizing gain in own wealth in accounting for the behavior of human players from four different cultures. We also show that the weights learned with our model for one culture outperform weights learned for other cultures when playing against opponents of the first culture.

(2017): Ein pleonastisches Oxymoron. Konstruktionsprobleme von Pierre Bourdieus Schlüsselkonzept der symbolischen Gewalt. In: Berliner Journal für Soziologie 27 (1), S. 7-33. DOI: 10.1007/s11609-017-0335-5
Abstract: According to Pierre Bourdieu, it is due to symbolic violence that social domination can be sustained without resorting to physical force. Because the dominated perceive their situation by means of categories which themselves are structured by power relations, they accept their own domination as legitimate, necessary, or functional. While the concept of symbolic violence takes center stage in Bourdieu's sociology, upon close analysis it turns out to be highly problematic. The paper shows that symbolic violence runs counter to the intentional and experiential structure of acts which are usually perceived as violent. As a result, the relation between symbolic and physical aspects of violence remains ambiguous in Bourdieu's writings. This, again, contributes to an inconsistent view on the history of violence and compromises the very normative grasp the extended notion of violence was actually intended to facilitate. Contrary to the prevailing interpretation, the article argues that the conceptual inconsistencies do not constitute a rhetorical artifice, but result from an unintended deviation from Bourdieu's fundamental terminological strategy to interlink the emic perspective of the actors and the etic perspective of sociology by means of seemingly contradictory phrases. Furthermore, Bourdieu's account of symbolic violence is not convincing with reference to the conceptualization of socialization and the (re)production of symbolic domination in concrete interaction. In a constructive vein the paper finally calls for the continuing analysis of the subtle and manifold modes of symbolic dominance by the use of more appropriate concepts.

(2017) : Speaking robots: The challenges of acceptance by the ageing society: 2017 26th IEEE International Symposium on Robot and Human Interactive Communication (RO-MAN): Lisbon, Portugal: IEEE Robotics & Automation Society, S. 1285-1290
DOI: https://doi.org/10.1109/ROMAN.2017.8172470 Abstract: The ability of robots to dialogue with humans appears as one critical Human-Machine Interaction feature when it comes to transferring robots into society. This ability gains additional importance when it comes to elderly people, since they find it more comfortable and natural to interact using voice, due to possible natural physical impairments that hinder the usage of some of the interaction modalities (e.g. touch screens). Challenges like recognition accuracy, distant speech, the idiosyncrasies of elderly voices (fading, muffled pronunciation, etc.), the effects of surrounding environment noise or the expressiveness of the robot when speaking, become highly relevant in the acceptance and usability of service robots by the ageing population. In this paper, we present the results, challenges and solutions developed during a nine-month iterative evaluation process that took place within the GrowMeUp project, with focus on speech recognition and synthesis. The paper concludes with an identification of open scientific and technological problems, based on our interpretation of results, which we identify as critical for the acceptance and usability of robots by an ageing society.

(2017): Smile for a while. The effect of employee-displayed smiling on customer affect and satisfaction. In: Journal of Service Management 28 (2), S. 284-304. DOI: 10.1108/JOSM-11-2015-0372
Abstract: Purpose - The purpose of this paper is to investigate the effect of employee-displayed smiling on customers' affective states (pleasure, arousal, and dominance) and satisfaction. Building on the stimulus-organism-response framework and theories of emotional contagion and feelings-as-information, the main hypothesis was that a smiling (vs non-smiling) employee significantly increases customer satisfaction through the mediating influence of pleasure. Design/methodology/approach - The study used a quasi-experimental two-group between-subjects design. A total of 210 customers at a large retail bank had a brief service encounter at the store entrance with a smiling (vs non-smiling) bank teller. Customers then went into the bank to do what they came to do. Before leaving the bank, customers completed a survey that included demographic information, affect (pleasure, arousal, and dominance), and measures of customer satisfaction. Findings - A smiling (vs non-smiling) employee had a significant positive impact on customer satisfaction. This effect was mediated by pleasure, but also, to a weaker extent, by dominance. These results contradict previous claims that smiling-induced emotional contagion does not remain throughout the completion of a service encounter. Practical implications - Managers should encourage, and potentially train, employees to act in ways associated with positive emotions. Managers could also hire employees based on how good they are at acting and expressing themselves in a genuinely positive manner and create a pleasant store atmosphere so that the feelings and behaviors displayed by frontline employees are genuine rather than inauthentic. Originality/value - This is the first experimental field study to examine the isolated effect that employee-displayed smiling has on customers' affective states and satisfaction. The results provide more direct evidence for the psychological processes justified by emotional contagion and feelings-as-information theories. Furthermore, the finding that dominance mediates the smiling-satisfaction link has never been shown before.

(2017) : The newest Road Revolution: Car as a Service In: VDE: AmE 2017 - Automotive meets Electronics; 8th GMM-Symposium: Berlin, Germany: VDE Verlag GmbH, S. 1-4. Online verfügbar unter https://ieeexplore.ieee.org/document/8335223/
Abstract: Since the invention of the first modern automobile, dated back in 1886 with the Benz Patent-Motorwagen, cars have experienced a continuous and endless evolution. This trend is still currently ongoing but, despite a tremendous technical improvement, during the last century cars have always been conceived as a means of transportation. Fast, reliable, efficient, ecological and even self-driving but the main purpose has always been transportation: now, with the arrival on the road of the Internet of Things (IoT), cars are next to a major conceptual revolution. This paper introduces in fact the concept of car as a service: it will offer a preliminary description of how sensors, actuators and radio-devices are going to transform these vehicles into a means to provide multiple services - not only transportation - both to the passengers and to the community, within the bigger framework of the Smart Cities.

(2017) : Turn-taking intention recognition using multimodal cues in social human-robot interaction: 2017 17th International Conference on Control, Automation and Systems (ICCAS): Jeju, Korea: IEEE, S. 1300-1302
DOI: https://doi.org/10.23919/ICCAS.2017.8204407 Abstract: Turn-taking is an essential social skill for human communication. The robot needs to recognize the end of turn for timely response to the user with little delay in human-robot interaction. In this paper, we propose a turn-taking intention recognition system that determine the timing of turn-taking using multimodal cues in social Human-Robot Interaction (sHRI). In order to evaluate the turn-taking intention recognition system, we collect multimodal data set and conducted experiments. To that end, we designed a human-robot interaction scenario including turn-taking and conducted an experiment with 30 participants using the humanoid robot NAO. In experiments, we validate recognition models trained multimodal dataset by machine learning methods.

(2017): Screens are a game changer. How environments influence social capital in the digital era. In: Cogent Social Sciences 3 (1). DOI: 10.1080/23311886.2017.1372028
Abstract: Accumulated social interactions shape social capital-that is, resources available through social ties-that benefits individuals, groups, and society at large. Personal electronic communication media and devices, termed herein screens, are a new type of environment interacting with other environments within an ecological system. Environments influence interpersonal communication in and across settings; yet little is known about the influence of context wherein virtual and in-person social interactions occur. After overviewing the characteristics of the screens, the present paper examines how four geographical contexts-middle-class suburbs, impoverished neighborhoods, urban neighborhoods, and college communities-can influence on the relationship between the screen and local social capital. Lastly, this paper discusses environmental design implications for reducing screen usage that harms social capital.

(2017): Reciprocation under status ambiguity. How dominance motives and spread of status value shape gift exchange. In: Social Networks 48, S. 142-156. DOI: 10.1016/j.socnet.2016.08.004
Abstract: How does status ambiguity affect reciprocation in gift exchange? We argue that actors in an exchange relationship delay reciprocation as a means of subtly claiming dominance when relative status is ambiguous. Using a two-step link-tracing sample of gift exchange dyads from an online social network site in the early days of social media, we analyze the probability of two-way exchange dyads and the timing of reciprocation while accounting for the nested and autocorrelated data structure. The results support the predicted inverted-U shape relationship between the hazard of reciprocation and status difference. This pattern is strongest when actors lack common foci of interaction from which relative status could be gauged accurately. In addition, a higher status individual tends to delay reciprocation longer than a lower-status individual, a finding consistent with the status competition explanation.

(2017): Cooperation Via Intimidation. An Emergent System of Mutual Threats can Maintain Social Order. In: Journal of Artificial Societies and Social Simulation 20 (4). DOI: 10.18564/jasss.3336
Abstract: Can human aggressiveness promote peaceful cooperation? Despite the seeming contradiction of these phenomena, our study suggests the answer is yes. We develop two agent-based models of cooperative interactions among aggressive agents threatening each other. In Model 1, we show that aggressive displays performed by dominance-seeking individuals create a system of mutual threats that effectively enforces cooperation and inhibits agents from escalating conflicts. This happens because agents observe each other fighting, which deters them from attacking each other due to aggressive reputations. In Model 2 we extend this effect to third-party interventions showing that forming alliances makes attacks more efficient and promotes the emergence of common rules determining whom to fight against. In such a state, social order is maintained by the existence of moral alliances - groups of agents willing to fight against norm violators. In summary, we argue that reputation for toughness and the aggressive predisposition of humans could have played an important role in the evolution of cooperation and moral systems.

(2017): The use and impact of Twitter at medical conferences. Best practices and Twitter etiquette. In: Seminars in Hematology 54 (4), S. 184-188. DOI: 10.1053/j.seminhematol.2017.08.003
DOI: https://doi.org/10.1053/j.seminhematol.2017.08.003 Abstract: The use of social media, and in particular, Twitter, for professional use among healthcare providers is rapidly increasing across the world. One medical subspecialty that is leading the integration of this new platform for communication into daily practice and for information dissemination to the general public is the field of hematology/oncology. A growing amount of research in this area demonstrates that there is increasing interest among physicians to learn not only how to use social media for consumption of educational material, but also how to generate and contribute original content in one’s interest/expert areas. One aspect in which this phenomenon has been highlighted is at the time of maximum new information presentation: at a major medical conference. Hematologists/oncologists are engaging regularly in one of the most common forms of social media, Twitter, during major medical conferences, for purposes of debate, discussion, and real-time evaluation of the data being presented. As interest has grown in this area, this article aims to review the new norms, practices, and impact of using Twitter at the time of medical conferences, and also explores some of the barriers and pitfalls that users are encountering in this emerging field.

(2017) : Robots educate in style: The effect of context and non-verbal behaviour on children's perceptions of warmth and competence In: IEEE Ro-Man: Human-robot collaboration and human assistance for an improved quality of life: IEEE RO-MAN 2017 : 26th IEEE International Symposium on Robot and Human Ineractive Communication : August 28-September 1, 2017, Lisbon, Portugal: Piscataway, NJ: IEEE, S. 449-455
Abstract: Social robots are entering the private and public domain where they engage in social interactions with nontechnical users. This requires robots to be socially interactive and intelligent, including the ability to display appropriate social behaviour. Progress has been made in emotion modelling. However, research into behaviour style is less thorough; no comprehensive, validated model exists of non-verbal behaviours to express style in human-robot interactions. Based on a literature survey, we created a model of non-verbal behaviour to express high/low warmth and competence - two dimensions that contribute to teaching style. In a perception study, we evaluated this model applied to a NAO robot giving a lecture at primary schools and a diabetes camp in the Netherlands. For this, we developed, based on expert ratings, an instrument measuring perceived warmth, competence, dominance and affiliation. We show that even subtle manipulations of robot behaviour influence children's perceptions of the robot's level of warmth and competence.

(2017): The power of status. What determines one's reactions to anger in a social situation?. In: Personality and Individual Differences 114, S. 61-68. DOI: 10.1016/j.paid.2017.03.057
Abstract: The present study examined how social status and gender determine anger expression and behavioral reactions toward experienced anger. In two experiments, anger was induced in a staged social interaction. Behavioral anger reactions were judged by observers. In Experiment 1 (equal status condition; N = 110) participants were provoked by a confederate, in Experiment 2 (low status condition; N = 116) participants were provoked by the experimenter. We found that participants expressed their anger to a lesser extent, were less resistant, and engaged in submissive behaviors if they had a lower status than the anger-target. As expected, gender had a moderating effect: While women's anger reactions were affected by having a lower status than the anger-target, men's anger reactions were affected by low status only when interacting with a female anger-target. Our findings provide new evidence regarding behavioral reactions to anger. zitiert von 2
