Informational social influence is driven by the desire to evaluate ambiguous situations correctly, whereas normative social influence is driven by the desire to be liked and gain social acceptance from another person. Although we know from research that humans can effectively use either of these techniques to persuade other humans, scholars have yet to examine the relative effectiveness of informational versus normative social influence when used by virtual agents. We report a study in which users interact with a system that persuades them either using informational or normative social influence. Furthermore, to compare agents to human interlocutors, users are told that the system is either tele-operated by a human (avatar) or fully-automated (agent). Using this design, we are able to compare the effectiveness of virtual agents (vs humans) in employing informational versus normative social influence. Participants interacted with the system, which employed a Wizard-of-Oz operated virtual agent that tried to persuade the user to agree with its rankings on a \"survival task.\" Controlling for initial divergence in rankings between user and the agent, there was a significant main effect such that informational social influence resulted in greater influence than normative influence. However, this was qualified by an interaction that approached significance; users were, if anything, more persuaded by informational influence when they believe the agent was AI (compared to a human), whereas there was no difference between the agent and avatar in the normative influence condition.","PeriodicalId":112642,"journal":{"name":"Proceedings of the 19th ACM International Conference on Intelligent Virtual Agents","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121966859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To engage their human users, artificial agents must be equipped with essential social skills such as facial expression communication. However, many artificial agents remain limited in this ability because they are typically equipped with a narrow set of prototypical Western-centric facial expressions of emotion that lack naturalistic dynamics. Our aim is to address this challenge by equipping artificial agents with a broader repertoire of socially relevant and culturally sensitive facial expressions (e.g., complex emotions, conversational messages, social and personality traits). To this aim, we use new, data-driven and psychology-based methodologies that can reverse-engineer dynamic facial expressions using human cultural perception. We show that our human-user-centered approach can reverse engineer many different, highly recognizable, and human-like dynamic facial expressions that typically outperform the facial expressions of existing artificial agents. By objectively analyzing these dynamic facial expression models, we can also identify specific latent syntactical signalling structures that can inform the design of generative models for culture-specific and universal social face signalling. Together, our results demonstrate the utility of an interdisciplinary approach that applies data-driven, psychology-based methods to inform the social signalling generation capabilities of artificial agents. We anticipate that these methods will broaden the usability and global marketability of artificial agents and highlight the key role that psychology must continue to play in their design.","PeriodicalId":112642,"journal":{"name":"Proceedings of the 19th ACM International Conference on Intelligent Virtual Agents","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126992397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a mixed design experiment, 78 participants interacted with a virtual human representing a sample from the non-photorealistic (NPR) to the photorealistic (PR) rendering continuity. We presented five rendering style samples scenarios, namely low fidelity all Pencil Shaded (APS), Low to Mid Fidelity Pencil Shader on virtual patient (VP) only (PS), Mid Fidelity All Cartoon Shaded (ACT), Mid to High Fidelity Cartoon Shader on VP only (CT), and relatively High Fidelity Human Like (HL) appearance, and compared how visual attention differed between groups of users. For this study, we employed an eye tracking system for collecting and analyzing users' gaze during interaction with the virtual human in a failure to rescue medical training simulation. Results suggests that users may spend more time in the simulations on the non-realistic fidelity continuum that necessarily do not involve interaction with the virtual human. However, users preferred visually attending to virtual humans in the middle and high fidelity visual appearance conditions when engaging virtual humans in simulated social face-to-face dialogue as compared to the other conditions","PeriodicalId":112642,"journal":{"name":"Proceedings of the 19th ACM International Conference on Intelligent Virtual Agents","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126247994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article we examine how perceptions of a virtual agent's mind shape behavior in human-agent negotiations. We varied descriptions and communicative behavior of virtual agents on two dimensions according to the mind perception theory:agency (cognitive aptitude) andpatiency (affective aptitude). Participants then engaged in negotiations with the different agents. People scored more points and engaged in shorter negotiations with agents described to be cognitively intelligent, and got lower points and had longer negotiations with agents that were described to be cognitively unintelligent. Accordingly, agents described as having low agency ended up earning more points than those with high agency. Within the negotiations themselves, participants sent more happy and surprise emojis and emotionally valenced messages to agents described to be emotional. This high degree of described patiency also affected perceptions of the agent's moral standing and relatability. In short, manipulating the perceived mind of agents affects how people negotiate with them. We discuss these results, which show that agents are perceived not only as social actors, but as intentional actors through negotiations.","PeriodicalId":112642,"journal":{"name":"Proceedings of the 19th ACM International Conference on Intelligent Virtual Agents","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132627842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Crisis and emergency risk communication remains a real challenge. The rapid response of emergency medical teams has an important role to play in preventing serious adverse events. During critical events, medical errors can be related to human or system factors, including ineffective team leadership, non-standardized team communication, a lack of global situation awareness, poor use of resources and inappropriate triage and prioritization. The VICTEAMS project aims at building a virtual environment for training rescue team leaders to non-technical skills. Depending on the leader abilities, the virtual characters playing the subordinates (e.g. nurses) reproduce a variety of behaviors like erroneous actions, followership attitudes or stress-based behaviors. A pedagogical director tailors the difficulty according to the dynamic profile of the learner.","PeriodicalId":112642,"journal":{"name":"Proceedings of the 19th ACM International Conference on Intelligent Virtual Agents","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123538597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We recruited 34 medicine students, who interacted with a VP suffering from depressive disorders. Results suggest good abilities for the students to use empathic sentences to communicate with the VP, but results varied regarding semiology extraction, students having a specialty in psychiatry performing better than their counterparts. Additionally, results suggest that students managed to keep an emotional distance during the interaction with the VP, but they let their emotions out when answering semiology questions. Positive feedbacks and limitations raised by students during debriefing interviews provide suggestions for improvements and ideas for future works.","PeriodicalId":112642,"journal":{"name":"Proceedings of the 19th ACM International Conference on Intelligent Virtual Agents","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125018415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
