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.

The question of the relation between the collective and the individual has had a long but patchy history within both philosophy and psychology. In this chapter we consider some arguments that could be adopted for the primacy of the we, and examine their conceptual and empirical implications. We argue that the we needs to be seen as a developing and dynamic identity, not as something that exists fully fledged from the start. The concept of we thus needs more nuanced and (...) differentiated treatment than currently exists, distinguishing it from the idea of a ‘common ground’ and discerning multiple senses of ‘we-ness’. At an empirical level, beginning from the shared history of human evolution and prenatal existence, a simple sense of pre-reflective we-ness, we argue, emerges from second-person I-you engagement in earliest infancy. Developmentally, experientially and conceptually, engagement remains fundamental to the we throughout its many forms, characterized by reciprocal interaction and conditioned by the normative aspects of mutual addressing.

The first part of the article examines some recent studies on the early development of social norms that examine young children’s understanding of codified rule games. It is argued that the constitutive rules than define the games cannot be identified with social norms and therefore the studies provide limited evidence about socio-normative development. The second part reviews data on children’s play in natural settings that show that children do not understand norms as codified or rules of obligation, and that the (...) norms that guide social interaction are dynamic, situated, and heterogeneous. It is argued that normativity is intersubjective and negotiable and starts to develop in the first year, emerging as a practical skill that depends on participatory engagement. Three sources of compliance are discussed: emotional engagement, nonverbal agreement, and conversation. (shrink)

Intentional communication is perceptually based and about attentional objects. Three attention mechanisms are distinguished: scanning, attention attraction, and attention-focusing. Attention-focusing directs the subject towards attentional objects. Attention-focusing is goal-governed (controlled by stimulus) or goal-intended (under the control of the subject). Attentional objects are perceptually categorised functional entities that emerge in the interaction between subjects and environment. Joint attention allows for focusing on the same attentional object simultaneously (mutual object-focused attention), provided that the subjects have focused on each other beforehand (subject-subject (...) attention). It results in intentional communication if the subjects attend to each other as subjects (i) capable of attending, and (ii) attending in a goal-intended way. Intentional communication is fundamentally imperative and adapted to action. (shrink)

We trace the difference between the ways in which apes and humans co–operate to differences in communicative abilities, claiming that the pressure for future–directed co–operation was a major force behind the evolution of language. Competitive co–operation concerns goals that are present in the environment and have stable values. It relies on either signalling or joint attention. Future–directed co–operation concerns new goals that lack fixed values. It requires symbolic communication and context–independent representations of means and goals. We analyse these ways of (...) co–operating in game–theoretic terms and submit that the co–operative strategy of games that involve shared representations of future goals may provide new equilibrium solutions.

An experimental paradigm that purports to test young children’s understanding of social norms is examined. The paradigm models norms on Searle’s notion of a constitutive rule. The experiments and the reasons provided for their design are discussed. It is argued that the experiments do not provide direct evidence about the development of social norms and that the concepts of a social norm and constitutive rule are distinct. The experimental data are re-interpreted, and suggestions for how to deal with the present (...) criticism are presented that do not require abandoning the paradigm as such. Then the conception of normativity that underlies the experimental paradigm is rejected and an alternative view is put forward. It is argued that normativity emerges from interaction and engagement, and that learning to comply with social norms involves understanding the distinction between their content, enforcement, and acceptance. As opposed to rule-based accounts that picture the development of an understanding of social norms as one-directional and based in enforcement, the present view emphasizes that normativity is situated, reciprocal, and interactive.

It is argued that the theory of situated cognition together with dynamic systems theory can explain the core of artistic practice and aesthetic experience, and furthermore paves the way for an account of how artist and audience can meet via the artist's work. The production and consumption of art is an embodied practice, firmly based in perception and action, and supported by features of the local, agent-centered and global socio-cultural contexts. Artistic creativity and aesthetic experience equally result from the dynamic (...) interplay between agent and context, allowing for artist and viewer to relate to the artist's work in similar ways. (shrink)

A recent version of the view that aesthetic experience is based in empathy as inner imitation explains aesthetic experience as the automatic simulation of actions, emotions, and bodily sensations depicted in an artwork by motor neurons in the brain. Criticizing the simulation theory for committing to an erroneous concept of empathy and failing to distinguish regular from aesthetic experiences of art, I advance an alternative, dynamic approach and claim that aesthetic experience is enacted and skillful, based in the recognition of (...) others’ experiences as distinct from one’s own. In combining insights from mainly psychology, phenomenology, and cognitive science, the dynamic approach aims to explain the emergence of aesthetic experience in terms of the reciprocal interaction between viewer and artwork. I argue that aesthetic experience emerges by participatory sense-making and revolves around movement as a means for creating meaning. While entrainment merely plays a preparatory part in this, aesthetic engagement constitutes the phenomenological side of coupling to an artwork and provides the context for exploration, and eventually for moving, seeing, and feeling with art. I submit that aesthetic experience emerges from bodily and emotional engagement with works of art via the complementary processes of the perception–action and motion–emotion loops. The former involves the embodied visual exploration of an artwork in physical space, and progressively structures and organizes visual experience by way of perceptual feedback from body movements made in response to the artwork. The latter concerns the movement qualities and shapes of implicit and explicit bodily responses to an artwork that cue emotion and thereby modulate over-all affect and attitude. The two processes cause the viewer to bodily and emotionally move with and be moved by individual works of art, and consequently to recognize another psychological orientation than her own, which explains how art can cause feelings of insight or awe and disclose aspects of life that are unfamiliar or novel to the viewer.

The subject of this book is the first person in thought and language. The main question concerns what we mean when we say 'J'. Related to it are questions about what kinds of self-consciousness and self-knowledge are needed in order for us to have the capacity to talk about ourselves. The emphasis is on theories of meaning and reference for 'J', but a fair amount of space is devoted to 'I' -thoughts and the role of the concept of the self (...) in cognition. The purpose is to give a picture of how we think and talk about ourselves in a wide range of circumstances. The topic has been discussed in numerous articles during the last decades, but rarely in the form of a monograph. I felt the need for a book of this kind while working on my dissertation. The manuscript is the result of many years of reflection on the self and indexicals. Some of the theories that I advance have developed as a result of my teaching an undergraduate course in the philosophy of language the last couple of years. (shrink)

By describing the aim of triangulation as locating the objects of thoughts and utterances, Davidson has given in the double role of accounting for both the individuation of content and the sense in which content necessarily is public. The focus of this article is on how triangulation may contribute to the individuation of content. I maintain that triangulation, interpreted in terms of joint attention, may serve to break into the intentional circle of meaning and belief, yet without forcing us to (...) renounce the claims concerning the interdependence of meaning and belief and the irreducibility of meaning.

Taking a psychological and philosophical outlook, we approach making as an embodied and embedded skill via the skilled artisan’s experience of having a corporeal, nonlinguistic dialogue with the material while working with it. We investigate the dynamic relation between maker and material through the lens of pottery as illustrated by wheel throwing, claiming that the experience of dialogue signals an emotional involvement with clay. The examination of Merleau-Ponty’s phenomenology of habit, the skilled intentionality framework, and material engagement theory shows that (...) while these theories explain complementary aspects of skillful engagement with the material world, they do not consider the dialogic dimension. By way of explanation, we submit that the artisan’s emotional engagement with the material world is based in openness and recognition and involves dialogue with the material. Drawing on the intimate relationship between movement and emotion, it promotes an open-ended manner of working and permits experiencing with the material, acting into its inherent possibilities. In conclusion, we suggest that dialogue, whether verbal or nonverbal, constitutes a primary means for making sense of the world at large, animate and inanimate. (shrink)

We explain metacognition as a management of cognitive resources that does not necessitate algorithmic strategies or metarepresentation. When pragmatic, world-directed actions cannot reduce the distance to the goal, agents engage in epistemic action directed at cognition. Such actions often are physical and involve other people, and so are open to observation. Taking a dynamic systems approach to development, we suggest that implicit and perceptual metacognition emerges from dyadic reciprocal interaction. Early intersubjectivity allows infants to internalize and construct rudimentary strategies for (...) monitoring and control of their own and others’ cognitions by emotion and attention. The functions of initiating, maintaining, and achieving turns make proto-conversation a productive platform for developing metacognition. It enables caregiver and infant to create shared routines for epistemic actions that permit training of metacognitive skills. The adult is of double epistemic use to the infant – as a teacher that comments on and corrects the infant’s efforts, and as the infant’s cognitive resource in its own right. (shrink)

The present account explains (i) which elements of nonverbal reference are intersubjective, (ii) what major effects intersubjectivity has on the general development of intentional communication and at what stages, and (iii) how intersubjectivity contributes to triggering the general capacity for nonverbal reference in the second year of life. First, intersubjectivity is analysed in terms of a sharing of experiences that is either mutual or individual, and either dyadic or triadic. Then it is shown that nonverbal reference presupposes intersubjectivity in communicative (...) intent indicating and referential behaviour, and indirectly in modifications of previous behaviour in response to communication failure. It is argued that different forms of intersubjectivity entail different types of communicative skills. A comprehensive analysis of data on gaze-related intersubjective behaviour in young infants shows that interaffectivity and interattentionality enable referential skills early in development and together allow for complex behaviour. Early referential skills, it is proposed, arise by other mechanisms than in nonverbal reference. Reliable and consistent use of nonverbal reference occurs when interaffectivity and interattentionality coalesce with interintentionality, which affords general cognitive skills that together permit a decontextualisation of communicative behaviour.

Several conditions for being an intrinsically intentional agent are put forward. On a first level of intentionality the agent has representations. Two kinds are described: cued and detached. An agent with both kinds is able to represent both what is prompted by the context and what is absent from it. An intermediate level of intentionality is achieved by having an inner world, that is, a coherent system of detached representations that model the world. The inner world is used, e.g., for (...) conditional and counterfactual thinking. Contextual or indexical representations are necessary in order that the inner world relates to the actual external world and thus can be used as a basis for action. To have full-blown intentionality, the agent should also have a detached self-awareness, that is, be able to entertain self-representations that are independent of the context. (shrink)

Abstract: To evaluate the explanation of change blindness in terms of misrepresentation and determine its role for Rosenthal’s higher-order thought theory of consciousness, we present an alternative account of change blindness that affords an independent outlook and provides a viable alternative. First we describe Rosenthal’s actualism and the notion of misrepresentation, then introduce change blindness and the explanation of it by misrepresentation. Rosenthal asserts that, in change blindness, the first-order state tracks the post-change stimulus, but the higher-order state misrepresents it. (...) We propose the alternative that both post-change and pre-change content can be tracked by the first-order state, and that in change blindness the higher-order thought represents the pre-change state, resulting in a good-enough representation: true but not veridical. We compare the two explanations with respect to available data and analyse the principal theoretical claims. Discussing the rationale of the alternative account, we conclude that there is good reason to conceive of the mind as satisficing, geared towards reliability instead of truth-tracking, and guided by representations that are good enough as opposed to complete or corresponding to the facts. We end with some methodological remarks concerning the risk of cognitive biases in interdisciplinary research that brings together empirical and philosophical claims. (shrink)

The notion of nonconceptual content in Dienes & Perner's theory is examined. A subject may be in a state with nonconceptual content without having the concepts that would be used to describe the state. Nonconceptual content does not seem to be a clear-cut case of either implicit or explicit knowledge. It underlies a kind of practical knowledge, which is not reducible to procedural knowledge, but is accessible to the subject and under voluntary control.

The present account explains which elements of the act of nonverbal reference are intersubjective, which major effects intersubjectivity has on the development of intentional communication and at what stages, and how intersubjectivity contributes to trigger the general capacity for nonverbal reference in the second year. First, intersubjectivity is analysed in terms of a mutual or individual, dyadic or triadic, sharing of experiences. It is then shown that nonverbal reference presupposes intersubjectivity relative to communicative-intent indicating and referential behaviour, and the modification (...) of previous behaviour in response to communication failure. It is argued that different forms of intersubjectivity entail different types of communicative skills. A comprehensive analysis of data on various gaze-related intersubjective behaviour in young infants shows that interaffectivity and interattentionality enable referential skills early in development and together allow for complex behaviour, but also that early referential skills arise by other mechanisms than in nonverbal reference and their functions do not overlap. Reliable and consistent use of nonverbal reference occurs when interaffectivity and interattentionality coalesce with interintentionality, which affords general cognitive skills, and these capacities together permit a decontextualisation of communicative behaviour.

To improvise together for the pure curiosity, joy, and beauty of it constitutes a central but often neglected ability of human beings. Integrating pragmatic, practical, and technical skills with conceptual understanding, improvisation is adaptive and collaborative. It seems made to counter the challenges of living in a fleeting present, unconstrained by physical and historical boundaries, and very likely has deep evolutionary roots. I present an account of joint improvisation in the performative arts based in reviews of empirical research in the (...) cognitive sciences, phenomenology, neuroscience, and philosophy, using examples from modern dance and jazz music. The account may be used for generating cross-disciplinary hypotheses about improvisation for investigation within a multitude of fields and is meant to encourage interdisciplinary work and collaboration between practitioners and academic researchers. The major goal is to elucidate the interaction dynamics that underlies joint improvisation by considering the variety of processes that support sensorimotor, experiential, emotional, meta-cognitive, and collaborative forms of interaction and lead to the coordination and synchronization of behavior. I claim that improvisation is an intelligent cognitive skill associated with meta-awareness, open to monitoring and control. It involves both automatized and flexible behavior and can occur without conscious awareness. Improvising in principle is independent of verbal language and higher-order thought, but nevertheless profits from the presence of multiple converging processes. (shrink)

In our response, we address four themes arising from the commentaries. First, we discuss the distinction between cognition and metacognition and show how to draw it within our framework. Next, we explain how metacognition differs from social cognition. The underlying mechanisms of metacognitive development are then elucidated in terms of interaction patterns. Finally, we consider measures of metacognition and suitable methods for investigating it.

How should the development of creativity be approached? Many accounts of children’s creativity focus on the relation between creativity and pretend play, placing make-believe and the mental exploration of possible scenarios about the world at the fore. Often divergent thinking and story-telling are used to measure creativity with fluency, originality, and flexibility as indicators. I will argue that the strong focus on conceptual processes and higher-order thought leaves procedural forms of creativity in the dark and hinders a proper investigation of (...) the development of creativity. Creativity involves both strategic and procedural elements and the mental and physical manipulation of ideas are equally important. Sahlin’s notion of rule-based creativity might serve as the starting-point for an approach to the development of creativity that is neutral as to the underlying nature of creativity and that permits investigating creativity independently of language. On this approach, creativity is characterized by the violation and subsequent replacement of a rule or norm that underlies a given activity with a novel strategy or procedure. When, where, and how children will manifest creativity is conditional on the kind of rule or norm that is violated. (shrink)

Recently, it has been suggested that at least somekinds of mental representation are strongly context-dependent. Not only what is represented, but also how, depends on the context and the subject's interaction with it. Theories about situated cognition stress the importance of the subject's bodily presence and physical activity in the environment for representing and thinking. What does this mean for creativity? Context-dependence can, it seems, both impede and support creativity. Is creativity a higher-level cognitive function, or does it mainly rely (...) on good old-fashioned know-how? (shrink)

The objects of attention can be located anywhere along the causal link from the source of stimuli to the final output of the vision system. As causes, they attract and control attention, and as products, they constitute targets of analysis and explicit comments. Stimulus-driven indexing creates pointers that support fast and frugal cognition.

Todays dispruptive technologies will change the layout of our cities and change urban life. Discussing what future cities need to thrive, how aesthitic value arises from embodied interaction and the need for walkable landscapes, I suiggest that enviroments that afford placing the second person first will make us more kind.

Artificiell intelligens (AI) är ett ungt forskningsområde där många av de grundläggande problemen förefaller att vara av filosofisk art.1 Ämnet har sina filosofiska rötter dels i traditionen från Leibniz, Frege, Russell och Hilbert, som strävar efter att formalisera principerna för exakt tänkande, dels i den klassiska mekanismen: idén att människan är en maskin och att det mänskliga tänkandet är en mekanisk process. Som en första approximation kan vi säga att AI är det vetenskapliga studiet av hur man konstruerar och bygger (...) maskiner (datorer) som är intelligenta (eller uppvisar intelligent beteende). Det är lätt att se att denna forskning aktualiserar frågor av filosofiskt slag. Hit hör problem som rör tänkandets natur samt förhållandet mellan medvetandet och kroppen. Inom AI ses ofta datorns arbetssätt som en modell för människans kognitiva processer och man föreställer sig kanske att hjärnan är ett slags dator. Eftersom hjärnan liknas vid en dator och en dator tänks arbeta rent mekaniskt i enlighet med ett givet program (en given algoritm), så föreställer man sig att samma sak bör gälla för hjärnan. Analogin hjärna-dator leder till föreställningen att tänkande inte är något annat än en dators mekaniska manipulerande av symboler i enlighet med givna formella regler. Denna uppfattning om tänkandets natur förefaller samtidigt problematisk: mekanisk manipulation av symboler förutsätter ingen förståelse av symbolernas innebörd; genuint tänkande, å andra sidan, tycks förutsätta sådan förståelse. Ibland verkar också analogin hjärna-dator i den motsatta riktningen. Eftersom hjärnan liknas vid en dator och hjärnan har en mental dimension, så föreställer man sig kanske att samma sak måste gälla för vissa datorer: synen på hjärnan som en dator leder till tanken att det borde vara möjligt att konstruera datorer som bokstavligen tänker, känner och förnimmer. Man föreställer sig kanske att man skall kunna konstruera ett artificiellt medvetande. Vi är alla förtrogna med datorer som (i en viss mening) kan lösa förelagda uppgifter på ett intelligent sätt, men följer det därav att dessa datorer kan tänka? Inte tänker väl en schackspelande dator på schack? Hur intelligent dagens datorer än beter sig, så verkar det ändå inte rimligt att säga att de har tankar, känslor eller upplevelser. Men kan man utesluta att vi någon gång i framtiden kommer att kunna konstruera datorer som verkligen förstår, är medvetna, och tänker? Dessa frågor rymmer många begreppsliga oklarheter. Vad är intelligens, tänkande, förståelse, medvetande? Hur förhåller sig intelligens och tänkande till medvetandets fenomenella sida: upplevelser och känslor? Om vad slags ting är det meningsfullt att säga att de har intelligens, medvetande, mentala tillstånd, etc.? Är det meningsfullt att säga detta om en hjärna, en maskin, en dator? Vad menas med en maskin (dator)? Hur kan vi veta (avgöra) om ett ting har intelligens, tankar, känslor eller upplevelser? I denna uppsats avser vi att närmare belysa sambandet mellan filosofi och AI samt kritiskt granska några av AI-forskningens förutsättningar inom filosofi och logik. (shrink)

In an experimental study of humans reactions to social motor intention in a humanoid robot, we showed that SMI cause the emergence of social interaction between human and robot. We investigated whether people would respond differently to a humanoid robot depending on the kinematic profile of its movement. A robot placed a block on a table in front of a human subject in three different ways. We designed the robot’s arm and upper body movements to manifest the human kinematic profile (...) of either a non-social motor intention or a social motor intention. In the control condition the robot performed an irregular movements. Once the robot had finished its task, the task of the human was to place another block on top of the first one. We distinguishedbetween social and non-social responses to the robot’s behavior based in gaze behavior and kinematic profile of the human’s arm movement during the task. Our results show that the behavior of the human can be modulated by the kinematics of a robot’s motor action. In several cases the participants reciprocated movements displaying social motor intention with movements with a similar kind of kinematics, attempting to make eye contact during the task. This shows that HRI can emerge implicitly by sensorimotor processing and suggests that implementing a mechanism for social-motor intention in social robots designed to interact spontaneously would be useful.

The goal of the present deliverable is to provide a developmental analysis of attentional intersubjectivity, which, as we show below, is a more inclusive notion than the more commonly used term ‘joint attention’. The use of the term ‘joint attention’ is not consistent in the literature, sometimes referring to the general phenomenon when two or more subjects attend to the same target, sometimes to more reciprocal situations in which the subjects also are aware of attending to the same target. Most (...) often solely visual attention has been described, but implicitly the descriptions have been thought to generalize to other modalities. The concepts introduced in this deliverable constitute an attempt to construct a coherent framework that will allow for distinguishing and comparing the range of behaviours that in the literature have been addressed as ‘joint attention’ behaviours. By attentional intersubjectivity we refer to the general case when two or more subjects simultaneously focus their attention on the same target. Attentional intersubjectivity will be further divided into types, according to which behaviours that are typically associated with attentional intersubjectivity occur during the interaction, and in which combinations. The result is that the over-all behaviour of the subjects during different types of attentional intersubjectivity differs. Our contentions are that: a) the types of attentional intersubjectivity identified in this report build on each other cumulatively and constitute different levels, and b) these levels correspond to evolutionary and developmental stages. In saying that the types are cumulative we mean that there is a progress by successive stages where each type is causally dependent on the type preceding it, and, furthermore, has increased in complexity as compared to previous types. While attentional intersubjectivity involves several perceptual modalities, for practical reasons, this study primarily concerns the visual modality. Our analysis is, however, intended also to be applicable to these other modalities. (shrink)

In situations that require creative thinking, there is no well-known procedure for how to reach the goal, or the solution. Among other things, it is not clear how choices between outcomes are made, or when the search for a solution should terminate. The article focusses on the evaluation of solutions that are generated during the search. The general question concerns the standards according to which evaluation is made. Are they at all similar to those that are used in normal problem-solving? (...) Another question relates to the stages of the processs during which evauation occurs. Is it during the whole process that evaluations are made, or only towards the end? (shrink)

Imperative and declarative pointing are distinct kinds of communicative acts that rely on different cognitive capacities in the speakers. Declarative pointing is an important precursor to language, seen from both an evolutionary and a developmental perspective. Declarative pointing is functionally independent of affective intersubjectivity, yet it is intimately related to it in development. It is argued that declarative pointing once evolved because it allows for the mutual evaluation of joint objects of attention. Interaffectivity and joint attention to a distal object (...) together constitute the prerequisites for using declarative pointing for the purpose of evaluation. Mutual evaluation has the benefits of enhancing co-operation and allowing for vicarious learning. It also makes possible the non-linguistic, active interrogation of others about their attitudes to jointly attended objects. (shrink)

Apperly's and Butterfill's theory about belief reasoning is taken as a starting-point for a discussion of how we make sense of other people's actions in real time. More specifically, the focus lies on how we can understand others' actions in terms of their epistemic states on an implicit level of processing. First, the relevant parts of Apperly's and Butterfill's theory are summarized. Then, their account of implicit theory of mind in terms of registration ascription and perceptual encountering is discussed and (...) rejected. While accepting Apperly's and Butterfill's general epistemic account of belief reasoning, the author suggests that implicit theory of mind involves visuomotor, second-person pragmatic representations. Moreover, this presentation emphasizes the central place of interaction, claiming that perceptual intentions-to-interact are fundamental to social understanding. Via the mechanism of social attention, social intentions automatically prompt agents to share and exchange sensorimotor, pragmatic information. (shrink)

The starting-point of this talk is the question which are the objects of attention? The answer simply is that there are no objects of attention as such, i.e., no generic objects of attention. Instead several kinds of object of attention can be discerned troughout the attention process. Which kind will constitute the actual object of attention in a certain situation depends on the task that the subject is performing and on the level of analysis. I will substantiate this claim by (...) giving an overview of the process that goes by the name of attention. (shrink)

The purpose of this paper is to clarify the role of value uncertainty and value instability in decision-making that concerns morally controversial issues. Value uncertainty and value instability are distinguished from moral uncertainty, and several types of value uncertainty and value instability are defined and discussed. The relations between value uncertainty and value instability are explored, and value uncertainty is illustrated with examples drawn from the social sciences, medicine and everyday life. Several types of factor producing value uncertainty and/or value (...) instability are then identified. They are grouped into three categories and discussed under the headings ‘value framing’, ‘ambivalence’ and ‘lack of self-knowledge’. The paper then discusses the role of value uncertainty in decision-making. The concluding remarks summarize what has been achieved and what remains to be done in this area. (shrink)

A variant of the compatrison theory of metaphor is put forward. The main points are a theory of metaphor belongs to semantics, not pragmatics, a metaphorical statement is a similarity statement, usually comparing descriptions of objects, a metaphor is a constellation of words connected by a certain kind of relation - the metaphorical link, metaphors are not necessarily asymmetric, what expressions copunt as metaphors in a certain language has to do with the semantic fields of the language in question.
