Using robots in educational contexts has already shown to be beneficial for a student's learning and social behaviour. For levitating them to the next level of providing more effective and human-like tutoring, the ability to adapt to the user and to express proactivity is fundamental. By acting proactively, intelligent robotic tutors anticipate possible situations where problems for the student may arise and act in advance for preventing negative outcomes. Still, the decisions of when and how to behave proactively are open questions. Therefore, this paper deals with the investigation of how the student's cognitive-affective states can be used by a robotic tutor for triggering proactive tutoring dialogue. In doing so, it is aimed to improve the learning experience. For this reason, a concept learning task scenario was observed where a robotic assistant proactively helped when negative user states were detected. In a learning task, the user's states of frustration and confusion were deemed to have negative effects on the outcome of the task and were used to trigger proactive behaviour. In an empirical user study with 40 undergraduate and doctoral students, we studied whether the initiation of proactive behaviour after the detection of signs of confusion and frustration improves the student's concentration and trust in the agent. Additionally, we investigated which level of proactive dialogue is useful for promoting the student's concentration and trust. The results show that high proactive behaviour harms trust, especially when triggered during negative cognitive-affective states but contributes to keeping the student focused on the task when triggered in these states. Based on our study results, we further discuss future steps for improving the proactive assistance of robotic tutoring systems.

事实证明，在学习环境中，社会智能代理（SIA）的部署在不同的应用领域具有多个优势。社会代理创作工具使场景设计师能够创造出对SIAS行为的高度控制的量身定制体验，但是，另一方面，这是有代价的，因为该方案及其创作的复杂性可能变得霸道。在本文中，我们介绍了可解释的社会代理创作工具的概念，目的是分析社会代理的创作工具是否可以理解和解释。为此，我们检查了创作工具Fatima-Toolkit是否可以理解，并且从作者的角度来看，其创作步骤可以解释。我们进行了两项用户研究，以定量评估Fatima-Toolkit的解释性，可理解性和透明度，从场景设计师的角度来看。关键发现之一是，法蒂玛 - 库尔基特（Fatima-Toolkit）的概念模型通常是可以理解的，但是基于情感的概念并不那么容易理解和使用。尽管关于Fatima-Toolkit的解释性有一些积极的方面，但仍需要取得进展，以实现完全可以解释的社会代理商创作工具。我们提供一组关键概念和可能的解决方案，可以指导开发人员构建此类工具。

Intelligent agents have great potential as facilitators of group conversation among older adults. However, little is known about how to design agents for this purpose and user group, especially in terms of agent embodiment. To this end, we conducted a mixed methods study of older adults' reactions to voice and body in a group conversation facilitation agent. Two agent forms with the same underlying artificial intelligence (AI) and voice system were compared: a humanoid robot and a voice assistant. One preliminary study (total n=24) and one experimental study comparing voice and body morphologies (n=36) were conducted with older adults and an experienced human facilitator. Findings revealed that the artificiality of the agent, regardless of its form, was beneficial for the socially uncomfortable task of conversation facilitation. Even so, talkative personality types had a poorer experience with the "bodied" robot version. Design implications and supplementary reactions, especially to agent voice, are also discussed.

我们展示了一个讲故事机器人，通过ACT-R认知架构控制，能够采用不同的说服技术和道德阶段，同时对关于Covid-19的一些主题进行交谈。论文的主要贡献包括在对话期间，在代理程序内记忆中可用的有说服力技术的使用（如果有）使用（如果有的话）的需求驱动模型的提议。在这种模型中测试的说服技术组合从使用讲故事，以绘制技术和基于修辞的参数。据我们所知，这代表了建立一个有说服力的代理商，能够整合关于对话管理，讲故事和说服技术以及道德态度的明确接地的认知假设的混合。本文介绍了63名参与者对系统的探索性评估结果

最近十年表明，人们对机器人作为福祉教练的兴趣越来越大。但是，尚未提出针对机器人设计作为促进心理健康的教练的凝聚力和全面的准则。本文详细介绍了基于基于扎根理论方法的定性荟萃分析的设计和道德建议，该方法是通过三项以用户为中心的涉及机器人福祉教练的三个不同的以用户为中心进行的，即：（1）与参与性设计研究一起进行的。 11名参与者由两位潜在用户组成，他们与人类教练一起参加了简短的专注于解决方案的实践研究，以及不同学科的教练，（2）半结构化的个人访谈数据，这些数据来自20名参加积极心理学干预研究的参与者借助机器人福祉教练胡椒，（3）与3名积极心理学研究的参与者以及2名相关的福祉教练进行了一项参与式设计研究。在进行主题分析和定性荟萃分析之后，我们将收集到收敛性和不同主题的数据整理在一起，并从这些结果中提炼了一套设计准则和道德考虑。我们的发现可以在设计机器人心理福祉教练时考虑到关键方面的关键方面。

Explainable AI (XAI) is widely viewed as a sine qua non for ever-expanding AI research. A better understanding of the needs of XAI users, as well as human-centered evaluations of explainable models are both a necessity and a challenge. In this paper, we explore how HCI and AI researchers conduct user studies in XAI applications based on a systematic literature review. After identifying and thoroughly analyzing 85 core papers with human-based XAI evaluations over the past five years, we categorize them along the measured characteristics of explanatory methods, namely trust, understanding, fairness, usability, and human-AI team performance. Our research shows that XAI is spreading more rapidly in certain application domains, such as recommender systems than in others, but that user evaluations are still rather sparse and incorporate hardly any insights from cognitive or social sciences. Based on a comprehensive discussion of best practices, i.e., common models, design choices, and measures in user studies, we propose practical guidelines on designing and conducting user studies for XAI researchers and practitioners. Lastly, this survey also highlights several open research directions, particularly linking psychological science and human-centered XAI.

在过去的几年中，围绕种族类人体机器人的有问题实践的讨论已经上升。为了彻底理解机器人在人类机器人互动（HRI）社区中如何理解机器人的“性别” - 即如何被操纵，在哪些环境中以及其对人们的看法和人们产生哪些影响的影响，为基础建立基础。与机器人的互动 - 我们对文献进行了范围的评论。我们确定了553篇与我们从5个不同数据库中检索的评论相关的论文。审查论文的最终样本包括2005年至2021年之间的35篇论文，其中涉及3902名参与者。在本文中，我们通过报告有关其性别的目标和假设的信息（即操纵性别的定义和理由），对机器人的“性别”（即性别提示和操纵检查），对性别的定义和理由进行彻底总结这些论文。 （例如，参与者的人口统计学，受雇的机器人）及其结果（即主要和互动效应）。该评论表明，机器人的“性别”不会影响HRI的关键构建，例如可爱和接受，而是对刻板印象产生最强烈的影响。我们利用社会机器人技术和性别研究中的不同认识论背景来提供有关审查结果的全面跨学科观点，并提出了在HRI领域前进的方法。

Taking advice from others requires confidence in their competence. This is important for interaction with peers, but also for collaboration with social robots and artificial agents. Nonetheless, we do not always have access to information about others' competence or performance. In these uncertain environments, do our prior beliefs about the nature and the competence of our interacting partners modulate our willingness to rely on their judgments? In a joint perceptual decision making task, participants made perceptual judgments and observed the simulated estimates of either a human participant, a social humanoid robot or a computer. Then they could modify their estimates based on this feedback. Results show participants' belief about the nature of their partner biased their compliance with its judgments: participants were more influenced by the social robot than human and computer partners. This difference emerged strongly at the very beginning of the task and decreased with repeated exposure to empirical feedback on the partner's responses, disclosing the role of prior beliefs in social influence under uncertainty. Furthermore, the results of our functional task suggest an important difference between human-human and human-robot interaction in the absence of overt socially relevant signal from the partner: the former is modulated by social normative mechanisms, whereas the latter is guided by purely informational mechanisms linked to the perceived competence of the partner.

情绪可以提供自然的交流方式，以补充许多领域中社交机器人（例如文本和语音）现有的多模式能力。我们与112、223和151名参与者进行了三项在线研究，以调查使用情绪作为搜救（SAR）机器人的交流方式的好处。在第一个实验中，我们研究了通过机器人的情绪传达与SAR情况有关的信息的可行性，从而导致了从SAR情况到情绪的映射。第二项研究使用控制控制理论是推导此类映射的替代方法。此方法更灵活，例如允许对不同的情绪集和不同机器人进行调整。在第三个实验中，我们使用LED作为表达通道为外观受限的室外现场研究机器人创建了情感表达。在各种模拟的SAR情况下，使用这些情感表达式，我们评估了这些表达式对参与者（采用救援人员的作用）的影响。我们的结果和提议的方法提供了（a）有关情感如何帮助在SAR背景下传达信息的见解，以及（b）在（模拟）SAR通信环境中添加情绪为传播方式的有效性的证据。

本文详细概述了将连续学习（CL）应用于单课的人类机器人互动（HRI）会议（AVG。31 +-10分钟）的案例研究，其中机器人的心理健康教练是积极的（n = 20）参与者的心理学（PP）练习。我们介绍了互动会议后与参与者进行的简短半结构访谈记录的数据的主题分析（TA）的结果，以及对统计结果的分析，证明了参与者的个性如何影响他们如何看待机器人的方式及其互动。

There has been a recent resurgence in the area of explainable artificial intelligence as researchers and practitioners seek to make their algorithms more understandable. Much of this research is focused on explicitly explaining decisions or actions to a human observer, and it should not be controversial to say that looking at how humans explain to each other can serve as a useful starting point for explanation in artificial intelligence. However, it is fair to say that most work in explainable artificial intelligence uses only the researchers' intuition of what constitutes a 'good' explanation. There exists vast and valuable bodies of research in philosophy, psychology, and cognitive science of how people define, generate, select, evaluate, and present explanations, which argues that people employ certain cognitive biases and social expectations towards the explanation process. This paper argues that the field of explainable artificial intelligence should build on this existing research, and reviews relevant papers from philosophy, cognitive psychology/science, and social psychology, which study these topics. It draws out some important findings, and discusses ways that these can be infused with work on explainable artificial intelligence.

近年来，虚拟学习已成为传统课堂教学的替代方法。学生参与虚拟学习可能会对满足学习目标和计划辍学风险产生重大影响。在虚拟学习环境中，有许多专门针对学生参与度（SE）的测量工具。在这项关键综述中，我们分析了这些作品，并从不同的参与定义和测量量表上突出了不一致之处。现有研究人员之间的这种多样性在比较不同的注释和构建可推广的预测模型时可能会出现问题。我们进一步讨论了有关参与注释和设计缺陷的问题。我们根据我们定义的七个参与注释的七个维度分析现有的SE注释量表，包括来源，用于注释的数据模式，注释发生的时间，注释发生的时间段，抽象，组合和组合水平的时间段，定量。令人惊讶的发现之一是，在SE测量中，很少有审查的数据集使用了现有的精神法法学验证量表中的注释中。最后，我们讨论了除虚拟学习以外的其他一些范围，这些量表具有用于测量虚拟学习中SE的潜力。

This article presents a survey of literature in the area of Human-Robot Interaction (HRI), specifically on systems containing more than two agents (i.e., having multiple humans and/or multiple robots). We identify three core aspects of ``Multi-agent" HRI systems that are useful for understanding how these systems differ from dyadic systems and from one another. These are the Team structure, Interaction style among agents, and the system's Computational characteristics. Under these core aspects, we present five attributes of HRI systems, namely Team size, Team composition, Interaction model, Communication modalities, and Robot control. These attributes are used to characterize and distinguish one system from another. We populate resulting categories with examples from recent literature along with a brief discussion of their applications and analyze how these attributes differ from the case of dyadic human-robot systems. We summarize key observations from the current literature, and identify challenges and promising areas for future research in this domain. In order to realize the vision of robots being part of the society and interacting seamlessly with humans, there is a need to expand research on multi-human -- multi-robot systems. Not only do these systems require coordination among several agents, they also involve multi-agent and indirect interactions which are absent from dyadic HRI systems. Adding multiple agents in HRI systems requires advanced interaction schemes, behavior understanding and control methods to allow natural interactions among humans and robots. In addition, research on human behavioral understanding in mixed human-robot teams also requires more attention. This will help formulate and implement effective robot control policies in HRI systems with large numbers of heterogeneous robots and humans; a team composition reflecting many real-world scenarios.

人类机器人协作组装系统提高了工作场所的效率和生产力，但可能会增加工人的认知需求。本文提出了一个在线和定量框架，以评估与同事的互动，即人类运营商或具有不同控制策略的工业协作机器人所引起的认知工作量。该方法可以监视操作员的注意力分布和上身运动学，从而受益于低成本立体声摄像机和尖端的人工智能算法的输入图像（即头姿势估计和骨架跟踪）。三种实验场景具有工作站特征和互动方式的变化，旨在测试我们在线方法的性能，以防止最新的离线测量。结果证明，我们基于视觉的认知负荷评估有可能将其集成到新一代的协作机器人技术中。后者将使人类的认知状态监测和机器人控制策略适应改善人类舒适，人体工程学和对自动化的信任。

情绪分析中最突出的任务是为文本分配情绪，并了解情绪如何在语言中表现出来。自然语言处理的一个重要观察结果是，即使没有明确提及情感名称，也可以通过单独参考事件来隐式传达情绪。在心理学中，被称为评估理论的情感理论类别旨在解释事件与情感之间的联系。评估可以被形式化为变量，通过他们认为相关的事件的人们的认知评估来衡量认知评估。其中包括评估事件是否是新颖的，如果该人认为自己负责，是否与自己的目标以及许多其他人保持一致。这样的评估解释了哪些情绪是基于事件开发的，例如，新颖的情况会引起惊喜或不确定后果的人可能引起恐惧。我们在文本中分析了评估理论对情绪分析的适用性，目的是理解注释者是否可以可靠地重建评估概念，如果可以通过文本分类器预测，以及评估概念是否有助于识别情感类别。为了实现这一目标，我们通过要求人们发短信描述触发特定情绪并披露其评估的事件来编译语料库。然后，我们要求读者重建文本中的情感和评估。这种设置使我们能够衡量是否可以纯粹从文本中恢复情绪和评估，并为判断模型的绩效指标提供人体基准。我们将文本分类方法与人类注释者的比较表明，两者都可以可靠地检测出具有相似性能的情绪和评估。我们进一步表明，评估概念改善了文本中情绪的分类。

最近的自主代理和机器人的应用，如自动驾驶汽车，情景的培训师，勘探机器人和服务机器人带来了关注与当前生成人工智能（AI）系统相关的至关重要的信任相关挑战。尽管取得了巨大的成功，基于连接主义深度学习神经网络方法的神经网络方法缺乏解释他们对他人的决策和行动的能力。没有符号解释能力，它们是黑色盒子，这使得他们的决定或行动不透明，这使得难以信任它们在安全关键的应用中。最近对AI系统解释性的立场目睹了可解释的人工智能（XAI）的几种方法;然而，大多数研究都专注于应用于计算科学中的数据驱动的XAI系统。解决越来越普遍的目标驱动器和机器人的研究仍然缺失。本文评论了可解释的目标驱动智能代理和机器人的方法，重点是解释和沟通代理人感知功能的技术（示例，感官和愿景）和认知推理（例如，信仰，欲望，意图，计划和目标）循环中的人类。审查强调了强调透明度，可辨与和持续学习以获得解释性的关键策略。最后，本文提出了解释性的要求，并提出了用于实现有效目标驱动可解释的代理和机器人的路线图。

Many theories, based on neuroscientific and psychological empirical evidence and on computational concepts, have been elaborated to explain the emergence of consciousness in the central nervous system. These theories propose key fundamental mechanisms to explain consciousness, but they only partially connect such mechanisms to the possible functional and adaptive role of consciousness. Recently, some cognitive and neuroscientific models try to solve this gap by linking consciousness to various aspects of goal-directed behaviour, the pivotal cognitive process that allows mammals to flexibly act in challenging environments. Here we propose the Representation Internal-Manipulation (RIM) theory of consciousness, a theory that links the main elements of consciousness theories to components and functions of goal-directed behaviour, ascribing a central role for consciousness to the goal-directed manipulation of internal representations. This manipulation relies on four specific computational operations to perform the flexible internal adaptation of all key elements of goal-directed computation, from the representations of objects to those of goals, actions, and plans. Finally, we propose the concept of `manipulation agency' relating the sense of agency to the internal manipulation of representations. This allows us to propose that the subjective experience of consciousness is associated to the human capacity to generate and control a simulated internal reality that is vividly perceived and felt through the same perceptual and emotional mechanisms used to tackle the external world.
