Togetherness in musical interaction

This paper presents a model of musical togetherness (MT), defined as the sense of musical connection that arises during real-time interaction and results in feelings of social connection, pleasure, and trust. The model comprises three layers. The first layer, which provides a backdrop for subsequent layers, comprises players’ knowledge and expectations about what will unfold during an interaction. The second layer comprises five processes that build upon one another: Belief in intentional partners in a shared musical environment, perceived liveness, and perceived responsivity mainly strengthen the social dimension of MT, while perceived embodied alignment and joint agency mainly strengthen the positive valence dimension. The third layer comprises rewarding feelings of social connection, pleasure and trust. These feelings feed back to affect the second layer processes, effectively guiding players’ musical decision-making and behaviour. They also feed back to affect the first layer, creating lasting effects on the way players approach musical interactions and relate to their interaction partners. MT should be seen as a fluid aspect of interaction that fluctuates alongside the aesthetic quality of the music. Players will sometimes sacrifice MT in the short term in order to improve the quality of their playing and strengthen their sense of MT in the long term. The MT model provides structure for a construct that has been used casually in the music psychology literature and has implications for how the performance behaviour of ensemble musicians is understood.

Constituent power and independence movements: On the founding and foundation of political orders and the meaning of political independence

This paper links the debates on constituent power and European independence movements in order to develop a theoretically compelling and empirically grounded conception of constituent power, as well as to assess in how far constituent power contributes to the meaning of political independence. In its first part, it builds upon recent republican contributions to the debates on corporate, joint and collective agency and argues that, even on individualist grounds, constituent power can convincingly be understood as a surplus of collective agency that corporate agency cannot encompass. In the second part of the paper, these preliminary theoretical considerations are confronted with the debates about Scotland's constitutional future and the 2014 independence referendum. This examination suggests further differentiation, but also facilitates insights into the interplay of the constituent power of the people with corporate forms of agency, as well as into changes of constituent peoples. In the final part, the paper inverts the perspective of inquiry to show that, once one is conscious of the complex relation between popular sovereignty and sovereignty that conceptions of corporate and collective agency help us to grasp, constituent power also proves to be an element of a compelling political conception of political independence.

Agency in negotiating partnerships in initial teacher education: shifting sands

ABSTRACT Despite over two decades of research, initial teacher education (ITE) partnerships remain problematic. Our study explores the development of a mandated ITE university–school partnership in Wales amidst significant educational reform. Through qualitative research, involving focus groups with 47 teacher educators from a university and 15 schools, we investigate their perceptions and experiences, focusing on shifts in professional roles and responsibilities. Our findings reveal disparities in the impact on the staff, including differences in changes to their roles and responsibilities, perceptions and experiences of agency and in the emotional effort required in the change process. We contend these findings have implications for all stakeholders involved in development of university–school ITE partnerships. In particular, the need for support for the development of individual and joint agency for all staff involved in partnership-building efforts. By shedding light on the complexities involved, we offer valuable insights for practitioners and researchers engaged in similar initiatives.

When performing actions with robots, attribution of intentionality affects the sense of joint agency.

Sense of joint agency (SoJA) is the sense of control experienced by humans when acting with others to bring about changes in the shared environment. SoJA is proposed to arise from the sensorimotor predictive processes underlying action control and monitoring. Because SoJA is a ubiquitous phenomenon occurring when we perform actions with other humans, it is of great interest and importance to understand whether-and under what conditions-SoJA occurs in collaborative tasks with humanoid robots. In this study, using behavioral measures and neural responses measured by electroencephalography (EEG), we aimed to evaluate whether SoJA occurs in joint action with the humanoid robot iCub and whether its emergence is influenced by the perceived intentionality of the robot. Behavioral results show that participants experienced SoJA with the robot partner when it was presented as an intentional agent but not when it was presented as a mechanical artifact. EEG results show that the mechanism that influences the emergence of SoJA in the condition when the robot is presented as an intentional agent is the ability to form similarly accurate predictions about the sensory consequences of our own and others' actions, leading to similar modulatory activity over sensory processing. Together, our results shed light on the joint sensorimotor processing mechanisms underlying the emergence of SoJA in human-robot interaction and underscore the importance of attribution of intentionality to the robot in human-robot collaboration.

Duet playing in dementia care: a new therapeutic music technology

Purpose Supporting the relational worlds of people living with dementia, especially the spousal dyad, is a growing focus in dementia care as is advancing the therapeutic use of music in dementia care. This paper describes a mixed-methods, multi-phase, iterative research study designed to develop the Music Memory Makers (MMM) Duet System, a novel therapeutic music technology, that allows non-musicians to play a personalized repertoire of songs arranged as duets. Methods Following a pilot phase to iteratively assess and refine the MMM Duet System for recreational and therapeutic purposes, multiple sources of data were used to investigate five older spousal dyads’ experiences with the system, two couples living with dementia and three who were not. We assessed perceptions of task difficulty, joint agency, and enjoyment as well as therapeutic benefits associated with enhancing the spousal relationship and sense of couplehood. Results Findings suggest playing meaningful songs together is an enjoyable interactive activity that prompts musical reminiscence, involves joint agency, and supports relationship continuity within a relational, positive approach to dementia care. All couples mastered the task, none evaluated it as “very challenging,” and positive couple interactions were evoked, commonly before and after playing the duets. Conclusions The MMM Duet System is recommended for further research and development as an innovative way to support couples living with dementia with commercial implications, and as a new music technology suitable for use as a research tool.

When is Human–Robot Joint Agency Effective? The Case of Cooperative Reaction Games

When is Human–Robot Joint Agency Effective? The Case of Cooperative Reaction Games

Joint action and spontaneity

AbstractThis paper poses a challenge to theories of joint action. In addition to the typical requirement of explaining how agents count as acting together as opposed to acting in parallel or independently—the togetherness requirement—it is argued that theories must explain how agents can be spontaneously joined such that they can act together spontaneously—the spontaneity requirement. To be spontaneously joined is to be immediately joined. The challenge arises because the typical means of satisfying the togetherness requirement, for example, planning, expressing willingness, and so forth, are forms of mediating, binding interaction and so seem to eliminate the possibility of spontaneity. Likewise, taking spontaneity seriously makes it difficult to see how the togetherness requirement can be simultaneously met. The challenge threatens the very idea of joint agency.

Effects of Reward Schedule and Avatar Visibility on Joint Agency during VR Collaboration.

Joint agency, a group-level sense of agency, has been studied as an essential social cognitive element while engaging in collaborative tasks. The joint agency has been actively investigated in diverse contexts (e.g., performance, reward schedules, and predictability), yet the studies were mostly conducted in traditional 2D computer environments. Since virtual reality (VR) is an emerging technology for remote collaboration, we aimed to probe the effects of traditional reward schedule factors along with novel VR features (i.e., avatar visibility) on joint agency during remote collaboration. In this study, we implemented an experiment based on a card-matching game to test the effects of the reward schedule (fair or equal) and the counterpart's avatar hand visibility (absent or present) on the sense of joint agency. The results showed that participants felt a higher sense of joint agency when the reward was distributed equally regardless of the individual performance and when the counterpart's avatar hand was present. Moreover, the effects of reward schedule and avatar hand visibility interacted, with a bigger amount of deficit for the absent avatar hand when the reward was distributed differentially according to performance. Interestingly, the sense of joint agency was strongly correlated to the level of collaborative performance, as well as to perceptions of other social cognitive factors, including cooperativeness, reward fairness, and social presence. These results contribute to the understanding of joint agency perceptions during VR collaboration and provide design guidelines for remote collaborative tasks and environments for users' optimal social experience and performance.

Autonomous agency, we‐agency, and social oppression

AbstractTheories of collective intentionality and theories of relational autonomy share a common interest in analyzing the social dynamics of agency. However, whereas theories of collective intentionality conceive of social groups primarily as intentional and voluntarily willed, theories of relational autonomy claim that autonomous agency is both scaffolded and constrained by social forces and structures, including the constraints imposed by nonvoluntary group membership. The question raised by this difference in view is whether social theorizing that overlooks the effects of nonvoluntary social group membership on individual and joint agency overlooks crucial aspects of the social dynamics of agency. To explore this question, this article first evaluates Michael Bratman's planning analysis of individual agency from the perspective of relational autonomy theory and compares it with a narrative self‐constitution account of temporally extended agency. It then evaluates Bratman's analysis of shared agency and discusses Shaun Gallagher and Deborah Tollefsen's concept of we‐narratives, which extends the notion of narrative construction to shared agency. Overall, the argument aims to show that if we are interested in understanding the social dynamics of agency, it is critical to attend to the way that agents exercise their intentional agency in relation to internalized and external social constraints.

Unwanted knowledge transmission

John Greco (2020) sets out to create a unified virtue-theoretic account of knowledge generation and transmission in his book The Transmission of Knowledge. One of the advantages of his view is that it can defend the achievement view from a known strand of counterexamples. To accomplish that, he relies on joint agency being essential to knowledge transmission. Joint agency can be characterized as a sort of interdependent and interactive cooperation between speaker and hearer that share an intention to transmit knowledge. This paper introduces the phenomenon of unwanted knowledge transmission which shows that joint agency, as Greco presents it, is not essential to knowledge transmission. Four types of unwanted knowledge transmissions will be introduced that pose threats to Greco’s account by showing that shared intention, a key characteristic of joint agency, is not present in all instances of knowledge transmission. Finally, some potential ways to defend Greco’s view will be considered and discussed.

Not just in sync: Relations between partners’ actions influence the sense of joint agency during joint action

When people perform joint actions together, they often experience a sense of joint agency (“we did that together”). The current study investigated whether relations between partners’ actions within joint actions that require precise interpersonal synchrony influence joint agency, above and beyond the degree of synchrony partners achieve. We employed a mixed-methods approach that combined a quantitative experiment with a qualitative analysis of post-experiment interviews. Partners produced synchronized tone sequences that comprised either constant pitch sequences (simple temporal alignment between partners’ actions) or musical duets (complex metrical and harmonic relations between partners’ actions). Participants reported stronger joint agency for duets than constant pitches, when comparing trials with equally good synchronization. Post-experiment interviews revealed that joint agency was also influenced by participants’ knowledge of the music and their perceptions of task performance, difficulty, and enjoyability. These findings further our understanding of joint agency for joint actions that require precise interpersonal synchrony.

Contingency and Social Change: Collective Engagement in Conditions of Radical Uncertainty

AbstractThis paper addresses the nexus between contingency, social engagement and change, through investigating the potential of severe (“disruptive”) contingency to bring about new forms of joint agency. By challenging Boltanski's notion of existential tests (which can only be experienced in isolation), the paper argues that social actors can experience disruptive contingent events in an inherently intersubjective manner. Although they severely hinder social interaction, disruptive contingent events enable a possibility of what might be called “negative common knowledge” between social actors which in turn renders certain societal norms meaningless. This possibility is mediated through processes of mutual engagement (calls between actors) that could, further, be transformed into a new “norm circle” (Dave Elder‐Vass). Social domination – in particular its “complex” variety – in this context appears as the obstructing of such transformation. A recent political episode in Serbia is analyzed to demonstrate the emancipatory potential of contingency and the logic of complex domination.

Can Tribal Nations Regain Their Lost Sovereignty Through Diplomacy?

Although Native Nations possess their own form of self-government, restrictive acts passed by Congress and Court Case precedents limit tribal sovereignty. This paper examines unfulfilled treaties between the federal government and tribal nations and the lack of negotiations between both powers. Acts such as Andrew Jackson’s Indian Removal Act in 1830 and the Indian Reorganization Act were created without tribal input, and therefore unpopular among Native Nations. Although Congress gradually worked towards encouraging state agencies and Native Nations to collaborate by passing the Indian Child Welfare Act of 1978 and the Indian Gaming Regulatory Act of 1988, these acts themselves were created and decided upon only by Congress without tribal input. US Supreme Court precedents also diminish Indian sovereignty through restrictive precedents that severely limit tribal governments’ judicial power. Due to Cherokee Nation v. Georgia, the primary legal precedent on the theory of Indian sovereignty, Native Nations lack the designation of a foreign state, and therefore a foreign sovereign. Precedents such as Oliphant v. Suquamish Indian Tribe and Montana v. United States limit Native Nations from possessing judicial and legislative authority over non-Indians on their land. Through cooperative agreements between tribal governments and local governments such as The Swinomish Cooperative Land Use Program and the Chippewa Flowage Joint Agency Management Plan Native Nations possess a means for their voice to be included when solving issues concerning them.

Commitments and the sense of joint agency

The purpose of this article is to explore the role commitments may play in shaping our sense of joint agency. First, we propose that commitments may contribute to the generation of the sense of joint agency by stabilizing expectations and improving predictability. Second, we argue that commitments have a normative element that may bolster an agent's sense of control over the joint action and help counterbalance the potentially disruptive effects of asymmetries among agents. Finally, we discuss how commitments may contribute to make acting jointly emotionally rewarding, both by improving coordination and by inducing or reinforcing the circumstances under which shared emotions emerge among co‐agents.

Game theory and partner representation in joint action: toward a computational theory of joint agency

The sense of agency – the subjective feeling of being in control of our own actions – is one central aspect of the phenomenology of action. Computational models provided important contributions toward unveiling the mechanisms underlying the sense of agency in individual action. In particular, the sense of agency is believed to be related to the match between the actual and predicted consequences of our own actions (comparator model). In the study of joint action, models are even more necessary to understand the mechanisms underlying the development of coordination strategies and how the subjective experiences of control emerge during the interaction. In a joint action, we not only need to predict the consequences of our own actions; we also need to predict the actions and intentions of our partner, and to integrate these predictions to infer their joint consequences. Understanding our partner and developing mutually satisfactory coordination strategies are key components of joint action and in the development of the sense of joint agency. Here we discuss a computational architecture which addresses the sense of agency during intentional, real-time joint action. We first reformulate previous accounts of the sense of agency in probabilistic terms, as the combination of prior beliefs about the action goals and constraints, and the likelihood of the predicted movement outcomes. To look at the sense of joint agency, we extend classical computational motor control concepts - optimal estimation and optimal control. Regarding estimation, we argue that in joint action the players not only need to predict the consequences of their own actions, but also need to predict partner’s actions and intentions (a ‘partner model’) and to integrate these predictions to infer their joint consequences. As regards action selection, we use differential game theory – in which actions develop in continuous space and time - to formulate the problem of establishing a stable form of coordination and as a natural extension of optimal control to joint action. The resulting model posits two concurrent observer-controller loops, accounting for ‘joint’ and ‘self’ action control. The two observers quantify the likelihoods of being in control alone or jointly. Combined with prior beliefs, they provide weighing signals which are used to modulate the ‘joint’ and ‘self’ motor commands. We argue that these signals can be interpreted as the subjective sense of joint and self agency. We demonstrate the model predictions by simulating a sensorimotor interactive task where two players are mechanically coupled and are instructed to perform planar movements to reach a shared final target by crossing two differently located intermediate targets. In particular, we explore the relation between self and joint agency and the information available to each player about their partner. The proposed model provides a coherent picture of the inter-relation of prediction, control, and the sense of agency in a broader range of joint actions.

Motor Coordination and Strategic Cooperation in Joint Action

Naturalistic joint action between two agents typically requires both motor coordination and strategic cooperation. However, these two fundamental processes have systematically been studied independently. We presented 50 dyads of adult participants with a novel collaborative task that combined different levels of motor noise with different levels of strategic noise, to determine whether the sense of agency (the experience of control over an action) reflects the interplay between these low-level (motor) and high-level (strategic) dimensions. We also examined how dominance in motor control could influence prosocial behaviors. We found that self-agency was particularly dependent on motor cues, whereas joint agency was particularly dependent on strategic cues. We suggest that the prime importance of strategic cues to joint agency reflects the co-representation of coagents’ interests during the task. Furthermore, we observed a reduction in prosocial strategies in agents who exerted dominant motor control over joint action, showing that the strategic dimension of human interactions is also susceptible to the influence of low-level motor characteristics.

The sense of agency in joint actions: A theory-driven meta-analysis

The sense of agency is the feeling of voluntarily controlling our actions and their effects. It represents a crucial component of self-awareness, and it is foundational to our perception of responsibility toward what we do as individuals acting in a social context. While the sense of agency has been widely investigated in individual contexts, much less is known about the agency experienced when subjects are involved in motor interactions, despite its relevance in the social domain. To fill this gap, here we review the literature on the sense of agency experienced during motor interactions. We aimed to test the reliability of this sense of joint agency across studies and define what features can modulate its explicit and implicit components. To this end, we performed a formal meta-analysis of studies investigating the implicit feeling of agency in joint actions and a systematic review of studies addressing explicit judgments of agency during motor interactions. Our review indicates that, during interactions, a sense of agency can also be experienced for the partner's actions, both at an implicit and explicit level, and that this possibility strongly depends on predictive sensorimotor mechanisms. Contextual cues play a crucial role too, but mainly on explicit agency judgments, while they do not affect the implicit feeling of agency. These results are discussed in light of current cognitive theories on motor awareness and motor interactions. We also propose a hierarchical model based on recursive predictive and comparative processes whereby the sense of joint agency is grounded on a weighted combination of sensorimotor and contextual cues. Finally, we discuss how this model may provide a framework for future research in the social and clinical domains.

The phenomenology of joint agency: the implicit structures of the shared life-world

The phenomenology of joint agency: the implicit structures of the shared life-world

Social-Contractarian Money

Abstract State capacity, stable currencies, and well functioning financial systems seem to be ‘package deals’ – one cannot have one without having all. I show that the intimate functional links among states, monies, and financial systems, ubiquitous across history and geography as they are, are not accidental. I do so by analytically ‘deriving’ first law and the polity, then money and finance, from a temporally extended implicit covenant that is both grounded in and facilitative of ongoing joint agency among persons. This lends to state and money alike their shared normative and, once formally systematized, legal character. I indicate throughout how this shared genesis, function, and normative character keep state, money, and ultimately finance practically ‘joined at the hip’, and manifest how polity and economy, indeed our very political and productive selves, are thus joined as well. To recognize and to ‘own’ this, I conclude, is not only to see that ‘the public’ must take a far more explicit role in finance, but also in a sense finally to own our own selves.

Musical Interaction Reveals Music as Embodied Language.

Life and social sciences often focus on the social nature of music (and language alike). In biology, for example, the three main evolutionary hypotheses about music (i.e., sexual selection, parent-infant bond, and group cohesion) stress its intrinsically social character (Honing et al., 2015). Neurobiology thereby has investigated the neuronal and hormonal underpinnings of musicality for more than two decades (Chanda and Levitin, 2013; Salimpoor et al., 2015; Mehr et al., 2019). In line with these approaches, the present paper aims to suggest that the proper way to capture the social interactive nature of music (and, before it, musicality), is to conceive of it as an embodied language, rooted in culturally adapted brain structures (Clarke et al., 2015; D’Ausilio et al., 2015). This proposal heeds Ian Cross’ call for an investigation of music as an “interactive communicative process” rather than “a manifestation of patterns in sound” (Cross, 2014), with an emphasis on its embodied and predictive (coding) aspects (Clark, 2016; Leman, 2016; Koelsch et al., 2019). In the present paper our goal is: (i) to propose a framework of music as embodied language based on a review of the major concepts that define joint musical action, with a particular emphasis on embodied music cognition and predictive processing, along with some relevant neural underpinnings; (ii) to summarize three experiments conducted in our laboratories (and recently published), which provide evidence for, and can be interpreted according to, the new conceptual framework. In doing so, we draw on both cognitive musicology and neuroscience to outline a comprehensive framework of musical interaction, exploring several aspects of making music in dyads, from a very basic proto-musical action, like tapping, to more sophisticated contexts, like playing a jazz standard and singing a hocket melody. Our framework combines embodied and predictive features, revolving around the concept of joint agency (Pacherie, 2012; Keller et al., 2016; Bolt and Loehr, 2017). If social interaction is the “default mode” by which human brains communicate with their environment (Hari et al., 2015), music and musicality conceived of as an embodied language may arguably provide a route toward its navigation.
