The question of what is shared in joint action has been discussed mainly with reference to the notion of collective intentionality. The problem of how to account for intentional states that are shared between two or more jointly engaged creatures is particularly relevant for actions that involve distal intentions. Yet there is another important kind of joint action, which so far has received less interest, at least by philosophers. This kind of action can be described in terms of a shared (...) motor engagement of two or more creatures with their surroundings. In this paper, I address the question of what is shared in such motor engagements. I suggest that joint motor actions come off through sharing particular kinds of feelings. In order to flesh out what it means to share feelings, I introduce the notion of ‘cross-creature embodiment’—the idea that a certain type of embodied mental event is constitutively tied to the body state of another, perceptually present creature in broadly the same way in which it is tied to the experiencing creature’s own. I end by suggesting that this notion makes available a new, albeit tentative, interpretation of recent neuroscientific evidence. (shrink)

Defined and formalized several decades ago, widely used in philosophy and game theory, the concept of common knowledge is still considered as problematic, although not always for the right reasons. I suggest that the epistemic status of a group of human agents in a state of common knowledge has not been thoroughly analyzed. In particular, every existing account of common knowledge, whether formal or not, is either too strong to fit cognitively limited individuals, or too weak to adequately describe their (...) state. I provide a realistic definition of common knowledge, based on a formalization of David Lewis’ seminal account and show that it is formally equivalent to probabilistic common belief. This leads to a philosophical analysis of common knowledge which answers several common criticisms and sheds light on its nature. (shrink)

According to many, joint intentional action must be understood in terms of joint intentions. Most accounts of joint intention appeal to a set of sophisticated individual intentional states. The author argues that standard accounts of joint intention exclude the possibility of joint action in young children because they presuppose that the participants have a robust theory of mind, something young children lack. But young children do engage in joint action. The author offers a revision of Michael Bratman’s analysis of joint (...) intention that reflects the socio-cognitive abilities young children do have. This revision makes sense of joint action among young children and equally well explains simple joint actions involving adults. Key Words: collective intentionality • joint action • child’s theory of mind • joint attention. (shrink)

Joint attention occurs when two (or more) individuals attend together to some object. It has been identified by psychologists as an early form of our joint engagement, and is thought to provide us with an understanding of other minds that is basic in that sophisticated conceptual resources are not involved. Accordingly, it has also attracted the interest of philosophers. Moreover, a very recent trend in the psychological and philosophical literature on joint attention consists of developing the suggestion that it holds (...) partially in virtue of communication: it is because we share our thoughts or feelings about an object that our individual attention becomes joint. This paper unpacks the communicative suggestion in a way that accounts for joint attention's basicness. (shrink)

On a widely held characterization, triadic joint attention is the capacity to perceptually attend to an object or event together with another subject. In the last four decades, research in developmental psychology has provided increasing evidence of the crucial role that this capacity plays in socio-cognitive development, early language acquisition, and the development of perspective-taking. Yet, there is a striking discrepancy between the general agreement that joint attention is critical in various domains, and the lack of theoretical consensus on how (...) to account for it. This paper pursues three interrelated aims: (i) it examines the contrast between reductive and non-reductive views of (triadic) joint attention, by bringing into focus the notion of recursive mindreading; (ii) it assembles, advances, and discusses a number of arguments against reductive views; (iii) finally, in dialogue with some prominent non-reductive views, it outlines the case for a non-reductive view that gives pride of place to the idea that co-attenders relate to one another as a ‘you’.

Cooperation admits of degrees. When factory workers stage a slowdown, they do not cease to cooperate with management in the production of goods altogether, but they are not fully cooperative either. Full cooperation implies that participants in a joint action are committed to rendering appropriate contributions as needed toward their joint end so as to bring it about, consistently with the type of action and the generally agreed upon constraints within which they work, as efficiently as they can, where their (...) contributions are sensitive to information (where available) about how others are contributing in the sense that they adjust as needed their contributions in light of information about how others are contributing to ensure effective pursuit of their joint end, where this includes rendering aid to other participants if needed, insofar as they are able. Full cooperation entails those cooperating are engaged in a joint intentional action. Some prominent studies of joint intentional action focus exclusively on cases of full cooperation (notably that of Michael Bratman (2014)). But not all joint intentional action is fully cooperative. One example is the work slowdown. Another example is provided by competitive games like chess and football, or sports like boxing and wrestling, where participants are clearly not intending to contribute to the pursuit of all of the goals of the others engaged in the activity, even when those goals are internal to the type of activity in question, but instead intend actively to frustrate some of them. In this paper, I provide a taxonomy of forms of non-cooperative behavior within the context of behavior that is still to some degree cooperative, and I argue that the minimal conditions of joint intentional action define minimal cooperative behavior, that is, that minimally joint intentional action is per se minimally cooperative behavior. I define in precise terms what that comes to, and how it is possible in cases in which it seems that one or more participants are in one or more ways acting so as to frustrate the contributions of other participants to their joint action.

Mutually adaptive interaction involves the robot as a partner as opposed to a tool, and requires that the robot is susceptible to similar environmental cues and behavior patterns as humans are. Recognition, or the acknowledgement of the other as individual, is fundamental to mutually adaptive interaction between humans. We discuss what recognition involves and its behavioral manifestations, and describe the benefits of implementing it in HRI.

Joint attention customarily refers to the coordinated focus of attention between two or more individuals on a common object or event, where it is mutually “open” to all attenders that they are so engaged. We identify two broad approaches to analyse joint attention, one in terms of cognitive notions like common knowledge and common awareness, and one according to which joint attention is fundamentally a primitive phenomenon of sensory experience. John Campbell’s relational theory is a prominent representative of the latter (...) approach, and the main focus of this paper. We argue that Campbell’s theory is problematic for a variety of reasons, through which runs a common thread: most of the problems that the theory is faced with arise from the relational view of perception that he endorses, and, more generally, they suggest that perceptual experience is not sufficient for an analysis of joint attention.

We propose two adjustments to the classic view of shared intentionality as based on conceptual-level cognitive skills. The first one takes into account that infants and young children display this capacity, but lack conceptual-level cognitive skills. The second one seeks to integrate cognitive and non-cognitive skills into that capacity. This second adjustment is motivated by two facts. First, there is an enormous difference between human infants and our closest living primate relatives with respect to the range and scale of goal (...) sharing and cooperation. Second, recent evidence suggests that there are hardly any differences in their mental-state attribution capacities. We argue therefore that our distinctively human capacity for shared intentionality is due to the effect on our cognitive skills of a practical attitude. Accordingly, we propose that cognitive and practical skills, working together, produce our capacity for shared intentionality, and review evidence suggesting that the practical skill in question consists in the ability to adopt an attitude of equality.

This article investigates the relationship between for-me-ness and sociality. I start by pointing out some ambiguities in claims pursued by critics that have recently pressed on the relationship between the two notions. I next articulate a question concerning for-me-ness and sociality that builds on the idea that, occasionally at least, there is something it is like ‘for us’ to have an experience. This idea has been explored in recent literature on shared experiences and collective intentionality, and it gestures towards the (...) question of the extent to which some social interactions make a difference in the phenomenal character of their participants’ experiences. Finally, I present a construal of for-us-ness that complements the received understanding of for-me-ness, by drawing on Alfred Schutz’ concept of the we-relationship, and on the idea of second-personal awareness, i.e. awareness of a ‘you’. The current proposal provides a suitable account of some basic forms of phenomenally manifest social connectedness, in a way that is cognitively undemanding and without incurring the costs of a sui generis plural pre-reflective self-awareness.

In this essay, I consider a kind of social group that I call ‘epistemic’. It is constituted by its members’ possession of perceptually grounded common knowledge, which endows them with a particular kind of epistemic authority. This authority, I argue, is invoked in the activity of ‘joint reminiscing’—of remembering together a past jointly experienced event. Joint reminiscing, in turn, plays an important role in the constitution of social and personal identity. The notion of an epistemic group, then, is a concept (...) that helps explain an important aspect of a subject’s understanding of who she is. (shrink)

Mutual perceptual knowledge is a prevalent feature of our everyday lives, yet appears to be exceptionally difficult to characterise in an acceptable way. This paper argues for a renewed understanding of Stephen Schiffer’s iterative approach to mutual knowledge, according to which mutual knowledge requires an infinite number of overlapping, embedded mental states. It is argued that the charge of ‘psychological implausibility’ that normally accompanies discussion of this approach can be offset by identifying mutual knowledge, not with the infinite iterations themselves, (...) but with the finite base which Schiffer proves is capable of generating those iterations. An understanding of this finite base as a primitive, relational property holding between two or more people, allows us to understand the iterations as an implicit and ‘harmless’ intrapersonal feature of what is an interpersonal phenomenon. The paper concludes by relating the account to joint attention in infant interaction. (shrink)

This article investigates the relationship between emotional sharing and the extended mind thesis. We argue that shared emotions are socially extended emotions that involve a specific type of constitutive integration between the participating individuals’ emotional experiences. We start by distinguishing two claims, the Environmentally Extended Emotion Thesis and the Socially Extended Emotion Thesis. We then critically discuss some recent influential proposals about the nature of shared emotions. Finally, in Sect. 3, we motivate two conditions that an account of shared emotions (...) ought to accommodate: Reciprocal Other-awareness and Integration. Consideration of and discussion of relational accounts of joint attention lead us to the proposal that a construal of socially extended emotions in terms of a constitutive integration of the participating individuals’ experiences is more promising than proposals that simply appeal to various forms of social situatedness, embeddedness, or scaffolding.

In regard to the explanation of actions that are governed by institutional rules, John R. Searle introduces the notion of a mental “background” that is supposed to explain how persons can acquire the capacity of following such rules. I argue that Searle’s internalism about the mind and the resulting poverty of his conception of the background keep him from putting forward a convincing explanation of the normative features of institutional action. Drawing on competing conceptions of the background of Heidegger and (...) Wittgenstein, I propose to revise Searle’s conception. The background of institutional agency can only provide a convincing explanation if it includes the context of actions and intersubjective structures of a shared life-world. I suggest that a further development of this idea would lead to the identification of the background with a web of social recognition. (shrink)

What enables everyday collective attitudes such as the intention of two persons to go for a walk together? Most current approaches are concerned with full-fledged col- lective attitudes and focus on the content, the mode or the subject of such attitudes. It will be argued that these approaches miss out an important explanatory enabling feature of collective attitudes: an experiential state, called a “sense of us”, in which a we-perspective is grounded. As will be shown, the sense of us pre-structures (...) collective intentional states and is thus relevant to an adequate understanding of collective atti- tudes. The argument receives indirect support by insights into distortions of interaction due to implicit stereotypes. (shrink)

La atención conjunta se da cuando dos sujetos atienden al mismo objeto a la vez, y el hecho es cognitivamente abierto. Existen dos enfoques al respecto: el primero reconoce que cada sujeto sabe que el otro está percibiendo lo mismo, es decir, es un co-perceptor; se trata, entonces, de explicar en qué consiste ser un co-perceptor. El segundo enfoque resalta que los sujetos saben que el objeto está siendo percibido por ambos; en dicho caso, se trata de explicar en qué (...) consiste que un objeto sea percibido como perceptualmente compartido. En este texto se analizan las razones del primer enfoque para mostrar por qué es desorientador; y se dan razones para validar el segundo enfoque. La respuesta a la apertura cognitiva abre el camino a la futura investigación en atención conjunta. (shrink)

We call those gestures “instrumental” that can enhance certain thinking processes of an agent by offering him representational models of his actions in a virtual space of imaginary performative possibilities. We argue that pointing is an instrumental gesture in that it represents geometrical information on one’s own gaze direction, and provides a ritualized template for initiating gaze coordination and joint attention. We counter two possible objections, asserting respectively that the representational content of pointing is not constitutive, but derived from language, (...) and that pointing directly solicits gaze coordination, without representing it. We consider two studies suggesting that attention and spatial perception are actively modified by one’s own pointing activity: the first study shows that pointing gestures help children link sets of objects to their corresponding number words; the second, that adults are faster and more accurate in counting when they point.

It is one thing for two or more persons to perceive the same object, and it is quite another for two or more persons to perceive the same object together. The latter phenomenon is called joint attention and has recently garnered considerable interest from psychologists. However, contemporary psychological research has not succeeded in clarifying how persons can share perception of an object. Joint attention thus stands in need of phenomenological clarification. Surprisingly, this has yet to be offered. Phenomenologists have provided (...) thoroughgoing analyses of perceptual experience, but have overlooked the perceptual experiences of co-perceivers; and, while a number of well-known phenomenologists have offered accounts of how one encounters other persons, they have neglected the phenomenon of perceptually attending to an object with other persons. This paper addresses a shortcoming of both contemporary psychological research and the phenomenological tradition by providing a phenomenological analysis of joint attention.
