Pretend play is generally considered to be a developmental landmark in Theory of Mind acquisition. The aim of the present paper is to offer a new account of the role of pretend play in Theory of Mind development. To this end I combine Hutto and Gallagher’s account of social cognition development with Matravers’ recent argument that the cognitive processes involved in engagement with narratives are neutral regarding fictionality. The key contribution of my account is an analysis of pretend play as (...) interaction with fictions. I argue that my account offers a better explanation of existing empirical data on the development of children’s pretend play and Theory of Mind than the competing theories from Leslie, Perner and Harris.

The combination of logic and game theory provides a fine-grained perspective on information and interaction dynamics, a Theory of Play. In this paper we lay down the main components of such a theory, drawing on recent advances in the logical dynamics of actions, preferences, and information. We then show how this fine-grained perspective has already shed new light on the long-term dynamics of information exchange, as well as on the much-discussed question of extensive game rationality.

Background and purpose: The functional understanding and examination of competitive anxiety responses as temporal events that unfold as time-to-competition moves closer has emerged as a topical research area within the domains of sport psychology. However, little is known from an inclusive and interaction oriented perspective. Using the multidimensional anxiety theory as a framework, the present study examined the temporal patterning of competitive anxiety, focusing on the dimensions of intensity, direction, and frequency of intrusions in athletes across gender and skill (...) level. Methods: Elite and semi-elite Table Tennis athletes from the Ghanaian league (N= 90) completed a modified version of Competitive State Anxiety Inventory-2 (CSAI-2) with the inclusion of the directional and frequency of intrusion scales at three temporal phases (7 days, two days and 1 hour) prior to a competitive fixture. Results: MANOVA repeated measures with follow-up analyses revealed significant interactions for between-subjects factors on all anxiety dimensions (intensity, direction and frequency). Notably, elite (international) female athletes were less cognitively anxious, showed more facilitative interpretation towards somatic anxiety symptoms and experienced less frequency of somatic anxiety symptoms than their male counterparts. However, both elite groups displayed appreciable level of self-confidence. For time-to-event effects, both cognitive and somatic anxiety intensity fluctuated whereas self-confidence showed a steady rise as competition neared. Somatic anxiety debilitative interpretation slightly improved 1 hour before competition whereas cognitive anxiety frequencies also increased progressively during the entire preparatory phase. Conclusions: Findings suggest a more dynamic image of elite athletes’ pre-competitive anxiety responses than suggested by former studies, potentially influenced by cultural differences. The use of psychological skills interventions that require effective structure, content, and timing in a composite manner is suggested. (shrink)

The flow state – an experience of complete absorption in an activity – is linked with less self-referential processing and increased arousal. We used the heart-evoked potential, an index representing brain–heart interaction, as well as indices of peripheral physiology to assess the state of flow in individuals playing a video game. 22 gamers and 21 non-gamers played the video game Thumper for 25 min while their brain and cardiorespiratory signals were simultaneously recorded. The more participants were absorbed in the (...) game, the less they thought about time and the faster time passed subjectively. On the cortical level, the fronto-central HEP amplitude was significantly lower while playing the game compared to resting states before and after the game, reflecting less self-referential processing while playing. This HEP effect corresponded with lower activity during gameplay in brain regions contributing to interoceptive processing. The HEP amplitude predicted the level of absorption in the game. While the HEP amplitude was overall lower during the gaming session than during the resting states, within the gaming session the amplitude of HEP was positively associated with absorption. Since higher absorption was related to higher performance in the game, the higher HEP in more absorbed individuals reflects more efficient brain–heart interaction, which is necessary for efficient game play. On the physiological level, a higher level of flow was associated with increased overall sympathetic activity and less inhibited parasympathetic activity toward the end of the game. These results are building blocks for future neurophysiological assessments of flow. (shrink)

The present study examined early social game routines during natural face-to-face mother–infant interactions and their relationship with oxytocin. Forty-three mother–infant dyads were observed, when infants were 4 months old, during a procedure involving a baseline and a natural interaction, where mothers were instructed to interact with their infants as they would at home. During this procedure four saliva samples from mothers and infants were collected to determine levels of oxytocin at different time points. Social game routines and infant social (...) engagement (gaze, positive, and negative affect) were coded during the natural interaction. Social games were observed in 76.7% of the mother–infant dyads, and 46 different types of games were identified. Mothers initiated games to re-engage infants significantly more often than when infants were already engaged with them. During the games, infants showed more positive affect and less negative affect in comparison to the rest of the interaction. Finally, maternal increase in oxytocin from before to after the natural interaction was positively correlated with game rate and time spent in games, while infant increase in oxytocin from before to after the natural interaction was inversely related to game rate. These results indicate that social games are an inherent part of early mother–infant interactions, and their occurrence is associated with oxytocin of both infants and mothers. (shrink)

In "Playing with Sound," Karen Collins examines video game sound from the player's perspective.

This article explores and compares cross-gender interactions of first and third graders in one child care center. Three prevalent forms of interaction are discussed: teasing, disputing, and playing. The author argues that these three forms of interaction are related to the use of space: Teasing often occurs when space is constricted, disputing is often the result of invaded space, and playing requires shared space and varying levels of cooperation. By focusing on the relationship between space and interaction, (...) important power asymmetries appear. Since boys are more likely to initiate invasions and more likely to determine the rules and terms of the play, they maintain a greater amount of power and control. (shrink)

From the grotesque pavilions hidden in sixteenth century Italian gardens to the temporary structures in public space in the 70s and recent digitally augmented environments, architectures of play have long been designed to engage explorative experiences. The uncertainty of play allows us to probe new behaviors, to poke into the boundaries of subjectivity and to interact with people, things and systems in unexpected and unfamiliar ways. In this essay, we explore how an interactive system, situated in public space, may foster (...) explorative activities and enable the transformative power of play. Through the analysis of several computer-augmented architectures, we examine what interactive qualities might enhance the transformative power of play. Beginning with the Fun Palace, an early attempt to use cybernetics in order to encourage visitors to experiment with their habits, we move to contemporary projects including some of the author’s own work. The latter takes the advantage of existing public locations in order to insert exploratory play into everyday life. Through analysis of these projects, we discuss whether such environments raise our responsibility toward others within our surroundings; whether they enable us to transform our own established behaviors; and whether they empower us to reclaim public space.

Gupta has proposed a definition of strategic rationality cast in the framework of his revision theory of truth. His analysis, relative to a class of normal form games in which all players have a strict best reply to all other players’ strategy profiles, shows that game-theoretic concepts have revision-theoretic counterparts. We extend Gupta’s approach to deal with normal form games in which players’ may have weak best replies. We do so by adapting intuitions relative to Nash equilibrium refinements to the (...) revision-theoretic framework. We prove that there is a precise equivalence between trembling-hand perfect equilibria in two-player normal games and a revision-theoretic property. We then introduce lexicographic choice of action as a way to represent players’ expectations, which allows our analysis to reach full generality. Finally, we provide an example of the versatility of revision theory as applied to strategic interaction by formalizing a risk-and-compensation procedure of strategic choice in the revision-theoretic framework.

Simulations, in which healthcare professionals are observed in dialogue with role-played patients, are widely used for assessing professional skills. Medical education research suggests simulations should be as authentic as possible, but there remains a lack of linguistic research into how far such settings authentically reproduce talk. This article presents an analysis of a corpus of general practice simulations in the United Kingdom, comparing this to a dataset of real-life general practitioner consultations. Combining corpus linguistic and conversation analytic methodologies, key interactional (...) features of the simulations are identified, particularly those associated with successful/unsuccessful performance in terms of the examiner’s grading. The corpus analysis identifies various forms of the phrase ‘tell me more about’ to occur significantly more frequently in the simulations compared to real GP consultations, typically in the opening sequences and most frequently in successful cases. It falls to a conversation analysis of the data, examining this phrase within the interactional context of these opening sequences, to better understand the actions it performs. Successful candidates in the simulations are found to perform a consistent sequential pattern, often incorporating this phrase. Although simulated, these interactions have real professional consequences for those being assessed. Linguistic findings about what constitutes successful interaction or differences to real-life practice therefore have important implications for professional education and assessment. (shrink)

Using anthropological theory, this paper examines human–android interactions (HAI) as an emerging aspect of android science. These interactions are described in terms of adaptive learning (which is largely subconscious). This article is based on the observations reported and supplementary data from two studies that took place in Japan with a teleoperated android robot called Telenoid in the socialization of school children and older adults. We argue that interacting with androids brings about a special context, an interval, and a space/time for (...) reflection and imagination that was not there before. During the interaction something happens. There is adaptive learning and as a result, both children and older adults accepted Telenoid, and the children and older adults accepted each other. Using frames of play and ritual, we make sense and ‘capture’ moments of adaptive learning, and the feedback that elicits a social response from all study participants that results in self-efficacy and socialization. While “ritual” refers to the application of what has been learned and “play” means that there are no obvious consequences of what has been learned. This analysis illuminates new understanding about the uncanny valley, cultural robotics and the therapeutic potential of HAI. This has implications for the acceptance of androids in ‘socialized roles’ and gives us insight into the subconscious adaptive learning processes that must take place within humans to accept androids into our society. This approach aims to provides a clearer conceptual basis and vocabulary for further research of android and humanoid development. (shrink)

Interactions of fathers and their children with autism1 The aim of the present study was to compare the activity of fathers and their children with autism with those of children with Down syndrome, and normally developing children during the father-child interaction. Participants were 14 children with autism and their fathers, 15 children with Down syndrome and their fathers, and 16 normally developing children and their fathers. The age of subjects was between 3.0 and 6.0 years old. The study consisted (...) of one 15-minute free-play session in the father-child diad, taking place in the experiment room. Differences between the groups of fathers were found in terms of three variables under analysis: frequency of looking at the child, physical contact with the child and suggesting play. Children with autism brought objects to their fathers or pointed out objects and directed their fathers' attention by vocalising less frequently than children with Down syndrome and normally developing children. Moreover, children with autism exhibited the fewest vocalisations combined with looking at the father and exhibited many more behaviours involving running and moving about the room than normally developing children. Self-stimulating behaviours were the most frequent in children with autism, with no differences in that respect found between children with Down syndrome and normally developing children. The analysis of fathers' behaviour demonstrates that fathers of children with developmental disorders focus on observing their children and attempt to keep close contact with them to a larger extent than fathers of normally developing children. The pattern of differences in the activity of fathers of children with autism and children with Down syndrome does not paint a clear picture. In general, fathers from both groups actively sought to maintain contact with their children. Differences in the activity during play between children with autism and the other subjects in the study are consistent with the clinical features of autism. (shrink)

An interaction between the ways morality and society develop in the face of the challenges they are exposed to seems consistent with empirical evidence. However, within this frame man's instinct of self preservation and his individualism seem to play an important part. The former by its influence on the evolution of what I refer to as 'our social morality'. The latter by finding its expression in conservative and radical ideologies whose political confrontation appears to give rise to an evolutionary (...) develop ment. The paper draws attention to the fact that in the face of contemporary challenges the evolutionary development of our morals may determine whether the corresponding evolutionary development of our societies will approach the patterns of those of insects, or whether our highly developed individual istic traits will result in new moral trends creating a society which is better suited to the present characteristics of humankind. It is also argued that the present growth of international organizations for cooperation and peaceful co-existence should make it possible to build a society worthy of the human race, but that it could be done only if we are able to develop a sufficient sense of responsibility to deliberately keep over-consumption and human population within a natural balance.

This paper explores how preschools can be purposefully designed to aid cultural learning through guided play practices. In recent literature, there has been a renowned interest in the role of the exogenous environment in psychological processes, including learning. The idea that the design of preschools can meaningfully be seen as cultural niche construction and that guided play practices in these environments can aid the preparation for cultural action is promoted, and a theoretical framework is presented. The empirical data draw from (...) a synthesis from three ethnographic research sites in multilingual communities, and data are used to explore how cultural affordances are used in designed environments as part of guided play practices. The results indicate how niche construction of affordances aid cultural learning and is achieved through both direct guided play interaction between teachers and children and also in the way of the indirect design of environments that is incorporated in children’s peer play. It is discussed what this means for play research as well as for guided play practices that aim to promote cultural learning. (shrink)

An important shift is taking place in social cognition research, away from a focus on the individual mind and toward embodied and participatory aspects of social understanding. Empirical results already imply that social cognition is not reducible to the workings of individual cognitive mechanisms. To galvanize this interactive turn, we provide an operational definition of social interaction and distinguish the different explanatory roles – contextual, enabling and constitutive – it can play in social cognition. We show that interactive processes (...) are more than a context for social cognition: they can complement and even replace individual mechanisms. This new explanatory power of social interaction can push the field forward by expanding the possibilities of scientific explanation beyond the individual. (shrink)

Based on a design-based research project and long-term observations of children’s play in school, this article develops the concept of play order, which points to interaction, coherence and holistic orientation as central values for the approach to play in school. Through concrete empirical analysis, the article shows how play in school is established and maintained, and how school as context interacts with play, which is often in ways that undermine the space and opportunities play is given. Based on existing (...) research, the article is critical of the tendency to accord a secondary role to play in school or to instrumentalize play as a didactic tool for learning. The article links to existing play theory, but at the same time develops the concept of play order, through an ecosystemic understanding, which makes it possible to look holistically at how play in school can be integrated and provided for. Considering that more and more pedagogues are working in schools and directly involved in teaching, and afterschool clubs are increasingly handling schooling tasks, the authors of the article argue that play is worthy of recognition in both practice and theory.

The return of a classic book about games and play that illuminates the relationship between the well-played game and the well-lived life. In The Well-Played Game, games guru Bernard De Koven explores the interaction of play and games, offering players—as well as game designers, educators, and scholars—a guide to how games work. De Koven's classic treatise on how human beings play together, first published in 1978, investigates many issues newly resonant in the era of video and computer games, including (...) social gameplay and player modification. The digital game industry, now moving beyond its emphasis on graphic techniques to focus on player interaction, has much to learn from The Well-Played Game. De Koven explains that when players congratulate each other on a “well-played” game, they are expressing a unique and profound synthesis that combines the concepts of play (with its associations of playfulness and fun) and game (with its associations of rule-following). This, he tells us, yields a larger concept: the experience and expression of excellence. De Koven—affectionately and appreciatively hailed by Eric Zimmerman as “our shaman of play”—explores the experience of a well-played game, how we share it, and how we can experience it again; issues of cheating, fairness, keeping score, changing old games (why not change the rules in pursuit of new ways to play?), and making up new games; playing for keeps; and winning. His book belongs on the bookshelves of players who want to find a game in which they can play well, who are looking for others with whom they can play well, and who have discovered the relationship between the well-played game and the well-lived life.

The purpose of this article is to present a phenomenological description of how athletes in specific risk sports explore human interaction with natural elements. Skydivers play with, and surf on, the encountering air while falling towards the ground. Kayakers play on the waves and with the stoppers and currents in the rivers. Climbers are ballerinas of the vertical, using cracks and holds in the cliffs to pull upwards against gravity forces. The theoretical background for the description is found in (...) the phenomenology of Heidegger and Merleau-Ponty. The phenomenology of Husserl focused on the theoretical intentionality of the transcendental ego. With Heidegger the human being's concrete and practical interaction with the environing world moved to the foreground. Heidegger's analyses of ?equipmentality? also throw important light on equipmentality in sports and how we deal with tools and equipment in sports. However, in Heidegger's analyses the body resides in the background both as subject and object. The importance of the active body-subject is well documented in the work of Merleau-Ponty, and also Todes. The human being is a bodily ?being-in-the-world? and the body is the active medium through which the world is grasped. The body is however also situated and aligned with the fundamental dimensions of the world, with vertical gravity and with horizontal action space. In this article I show in a concrete way how in some sports we use fundamental characteristics of the environing world in a mode of playfulness. In these sports human beings play in an extreme way with fundamental elements of nature. The article thus puts phenomenology to a test. It should be able to move from general characteristics to specific features of our bodily human involvement with the environing world. (shrink)

Pain perception is influenced by several factors, and among them, affect, sex, and perception of bodily signals are assumed to play a prominent role. The aim of the present study is to explore how sex, cardiac interoceptive accuracy, and the interaction of the latter two influence the perception of experimentally induced pain. We investigated a large sample of young adults (n= 159, 50.9% female, age: 23.45, SD = 3.767), assessing current positive and negative affective state with the Positive and (...) Negative Affect Schedule (both involved as control variables), cardiac interoceptive accuracy with the mental heartbeat tracking task, and pain sensitivity with electrical stimulation on the back of the dominant hand, applying a repeated-measures staircase protocol. Males showed a significantly higher pain threshold and tolerance level than females, whereas cardiac interoceptive accuracy was not associated with pain sensitivity. The impact of sex × cardiac interoceptive accuracy interaction was significant for pain threshold only, while pain tolerance was predicted only by sex. According to these findings, the associations between pain sensitivity, cardiac IAc, and sex might be more complicated than it was supposed in previous studies. Interactions between factors impacting pain perception appear worthy of further investigation. (shrink)

Knowledge of the context and development of playful expressions in chimpanzees is limited because research has tended to focus on social play, on older subjects, and on the communicative signaling function of expressions. Here we explore the rate of playful facial and body expressions in solitary and social play, changes from 12- to 15-months of age, and the extent to which social partners match expressions, which may illuminate a route through which context influences expression. Naturalistic observations of seven (...) chimpanzee infants ( Pan troglodytes ) were conducted at Chester Zoo, UK ( n = 4), and Primate Research Institute, Japan ( n = 3), and at two ages, 12 months and 15 months. No group or age differences were found in the rate of infant playful expressions. However, modalities of playful expression varied with type of play: in social play, the rate of play faces was high, whereas in solitary play, the rate of body expressions was high. Among the most frequent types of play, mild contact social play had the highest rates of play faces and multi-modal expressions (often play faces with hitting). Social partners matched both infant play faces and infant body expressions, but play faces were matched at a significantly higher rate that increased with age. Matched expression rates were highest when playing with peers despite infant expressiveness being highest when playing with older chimpanzees. Given that playful expressions emerge early in life and continue to occur in solitary contexts through the second year of life, we suggest that the play face and certain body behaviors are emotional expressions of joy, and that such expressions develop additional social functions through interactions with peers and older social partners.

In this article we study the beginnings of sociodramatic play. We examine the pretend play interactions of a Dutch girl, Peggy, and focus on her transition into sociodramatic play. Initially, Peggy interprets only some elements of her play interactions at the pretend level. At age 2;9, Peggy shows symbolic substitution for objects and actions. In the course of seven months, the features participants, roles and place gradually become substituted and specified at the pretend level in Peggy's play. In the earlier (...) play interactions, Peggy and her interaction partner keep a discourse identity and only assign new meaning to objects and to their local acts. In a later play interaction, Peggy and her playmate take roles and interpret their situated identities in the pretend layer. The use of situated identities allows for a range of possible acts and a sociodramatic story line, which increases the complexity of the pretend play. (shrink)

Problems of cooperation have often been simplified as the choice between defection and cooperation, although in many empirical situations it is also possible to walk away from the interaction. We present the results of two lab-in-the-field experiments with a diverse pool of subjects who play optional and compulsory public goods games both with and without punishment. We find that the most important institution to foster cooperation is punishment, which is more effective in a compulsory game. In contrast to Rand (...) and Nowak (Nat Commun 2(1):1–7, 2011), we find that loners are not responsible for anti-social punishment, which is mostly imputable to low-contributors (free-riders). Loners neither totally free-ride nor they significantly punish cooperators (or other types of players): they simply avoid all forms of participation whenever possible. (shrink)

In ethical reflections on new technologies, a specific type of argument often pops up, which criticizes scientists for “playing God” with these new technological possibilities. The first part of this article is an examination of how these arguments have been interpreted in the literature. Subsequently, this article aims to reinterpret these arguments as symbolic arguments: they are grounded not so much in a set of ontological or empirical claims, but concern symbolic classificatory schemes that ground our value judgments in the (...) first place. Invoking symbolic arguments thus refers to how certain new technologies risk undermining our fundamental symbolic distinctions by which we organize and evaluate our interactions with the world and in society. Such symbolic distinctions, moreover, tend to be resilient against logical argumentation, mainly because they themselves form the basis on which we argue in the cultural and ethical sphere in the first place. Therefore, effective strategies to evaluate and counter these arguments require another approach, showing that these technologies either do not challenge these classifications or, if they do, how they can be accompanied by the proper actions to integrate these technologies into our society.

Interaction between adults and infants by nature constitutes a strong powerasymmetry relationship. Based on the assumption that communicative practices with infants are inseparably intertwined with broader cultural ideologies of good child care, this paper will contrast how parents in two distinct socio-cultural communities deal with power asymmetry in interactions with 3-months old infants. The study consists of a microanalysis of videotaped free play mother-infant interactions from 20 middle class families in Muenster, Germany and 20 traditional farming Nso families in (...) Kikaikelaki, Cameroon. Analysis followed a discursive psychology approach. The focus of analysis is on how mothers handle and negotiate power-distance in these interactions and what discursive strategies they draw on. Mothers in both groups used various forms of directives and control strategies. The Muenster mothers, however, mainly used mitigated directives that can be seen as strategies to reduce the competence gap between mother and child, while the Nso mothers mainly used upgraded directives to stress the hierarchical discrepancy between mother and child. The different strategies are discussed in light of the prevailing broader cultural ideologies and the normative orientations that they reflect. Finally, the findings are discussed with regard to possible developmental consequences of these distinct cultural practices for the child. Keywords: power-asymmetry; mother-infant interaction; discursive psychology; culture; Nso farmers; Muenster middle class families. (shrink)

We investigate the emergence of iconicity, specifically a bouba-kiki effect in miniature artificial languages under different functional constraints: when the languages are reproduced and when they are used communicatively. We ran transmission chains of participant dyads who played an interactive communicative game and individual participants who played a matched learning game. An analysis of the languages over six generations in an iterated learning experiment revealed that in the Communication condition, but not in the Reproduction condition, words for spiky shapes tend (...) to be rated by naive judges as more spiky than the words for round shapes. This suggests that iconicity may not only be the outcome of innovations introduced by individuals, but, crucially, the result of interlocutor negotiation of new communicative conventions. We interpret our results as an illustration of cultural evolution by random mutation and selection. (shrink)

Speech comprehension across languages depends on encoding the pitch variations in frequency-modulated sweeps at different timescales and frequency ranges. While timescale and spectral contour of FM sweeps play important roles in differentiating acoustic speech units, relatively little work has been done to understand the interaction between the two acoustic dimensions at early cortical processing. An auditory oddball paradigm was employed to examine the interaction of timescale and pitch contour at pre-attentive processing of FM sweeps. Event-related potentials to frequency (...) sweeps that vary in linguistically relevant pitch contour and timescale in Mandarin Chinese were recorded. Mismatch negativities were elicited by all types of sweep deviants. For local timescale, FM sweeps with F0 contours yielded larger MMN amplitudes than F1 contours. A reversed MMN amplitude pattern was obtained with respect to F0/F1 contours for global timescale stimuli. An interhemispheric asymmetry of MMN topography was observed corresponding to local and global-timescale contours. Falling but not rising frequency difference waveforms sweep contours elicited right hemispheric dominance. Results showed that timescale and pitch contour interacts with each other in pre-attentive auditory processing of FM sweeps. Findings suggest that FM sweeps, a type of non-speech signal, is processed at an early stage with reference to its linguistic function. That the dynamic interaction between timescale and spectral pattern is processed during early cortical processing of non-speech frequency sweep signal may be critical to facilitate speech encoding at a later stage.

The aim of this study was to examine the interactive effects of situational variables on teams’ technical performance in the UEFA Champion League. Match data of 19 technical actions and events were collected and classified into three groups during eight seasons. Repeated-measures analysis of variance was used to identify the differences in the technical performances among teams. Results showed that the significant differences in the technical performance between the group stage and the knockout stage were only found in dribble and (...) yellow card. However, differences in the variables related to goal scoring and offense were more significant than in the variables related to defense under the comparisons across competition situations, and the differences in the variables related to defense were mainly detected in the yellow card. The number of variables that showed significant differences among match location and match outcome in the group stage were less than in the knockout stage. Therefore, the identified key performance indicators by considering the interactive effects of situational variables may provide detailed and practical insights for coaches to develop useful training interventions and match strategies for upcoming match playing in specific competition situations.

In the context of interspecies play involving humans, we find limitations when it comes to understanding most species. One reason for this may be the fact that we tend to anthropomorphize the other to be able to empathize with it. In light of this, how can we infer communication signs of other species so we are able to connect with the nonhuman world? We look for answers to this question by adopting a phenomenological approach that allows us to decentre from (...) the anthropocentric perspective. We highlight animal studies, especially those that extend to them the notion of play, and the studies on interspecies playful interaction conducted in the context of animal‐computer interaction. In addition, we propose considering empathy as an interspecies dialogical bridge with nonhumans. Finally, we argue about an expansion of the field of interaction design as an approach to the connection with the nonhuman world. (shrink)

How can we increase awareness and understanding of other cultures using interactive digital visualizations of past civilizations? In order to answer the above question, this book first examines the needs and requirements of virtual travelers and virtual tourists. Is there a market for virtual travel? Erik Champion examines the overall success of current virtual environments, especially the phenomenon of computer gaming. Why are computer games and simulations so much more successful than other types of virtual environments? Arguments that virtual environments (...) are impeded by technological constraints or by a paucity of evaluation studies can only be partially correct, for computer games and simulations are also virtual environments. Many of the underlying issues are caused by a lack of engagement with the philosophical underpinnings of culture, presence and inhabitation, and there are few exemplars that engage the public with history and heritage using interactive media in a meaningful and relevant manner. The intention of Playing With the Past is to help designers and critics understand the issues involved in creating virtual environments that promote and disseminate historical learning and cultural heritage through a close study of the interactive design principles at work behind both real and virtual places. Topics discussed include the design of virtual environments, and especially virtual heritage environments, virtual place-making, cultural presence, the pros and cons of game-style interaction, augmented reality projects, and appropriate evaluation methods. Virtual heritage environments discussed in the book include projects from Antarctica, Australia, Mexico, Malta, Egypt, Babylon, the Netherlands, Cambodia, and India. (shrink)

Lysosomal positioning is an important factor in regulating cellular responses, including autophagy. Because proteins encoded by disease‐responsible genes are involved in lysosomal trafficking, proper intracellular lysosomal trafficking is thought to be essential for cellular homeostasis. In the past few years, the mechanisms of lysosomal trafficking have been elucidated with a focus on adapter proteins linking motor proteins to lysosomes. Here, we outline recent findings on the mechanisms of lysosomal trafficking by focusing on adapter protein c‐Jun NH2‐terminal kinase‐interacting protein (JIP) 4, (...) which plays a central role in this process, and other JIP4 functions and JIP family proteins. Additionally, we discuss neuronal diseases associated with aberrance in the JIP family protein. Accumulating evidence suggests that chemical manipulation of lysosomal positioning may be a therapeutic approach for these neuronal diseases. (shrink)

Participatory Technology Assessment initiatives have usually been analyzed as if they existed in a social and political vacuum. This article analyzes the linkages that occur, in both directions, between the microcosm set up by a pTA exercise and the real world outside.

Rather than viewing them as a means to create the ideal conditions for real public debate, they are viewed here as an (...) additional public arena in which sociotechnical controversies are played out. This perspective is developed from the analysis of an interactive technology assessment exercise conducted by the French National Institute for Agricultural Research, on the topic of genetically modified vines.

Based on video-recordings of several weeks of rehearsals of a Japanese theater piece played by French actors, and adopting an ethnomethodological and conversation analytic perspective, this paper focuses on how the same few lines of a scene are subsequently enacted. In particular, it explores how the scene is played, not only in relation to the script but also to the situated moment-by-moment unfolding of embodied movements constituting the actions and achieving their detailed formatting and meaning. Whereas the dialogue refers to (...) the scripted text, we argue that the multimodal details of each scene constitute a unique situated course of action achieved for ‘another first time,’ whose multimodal configuration depends on the temporality and the shape of each step, gesture, and body posture, as they are embodied and responded to in the vivid present and its contingencies. We demonstrate this by revealing how variations of the scene are performed, explored, and serendipitously found by the actors. We focus in particular on embodied details like walking, sitting, hugging and kissing, and the sequential and temporal positions at which they co-occur with the lines of the script. The analysis demonstrates both the indexicality of the script interpretations and the creative contingencies of the embodied work of the actors. In this way, it aims at contributing to current growing literature revisiting theater rehearsal as a situated activity and an interactional multimodal achievement. (shrink)

Textbooks have played the leading role in academic education for centuries and their form has evolved, adapting to the needs of students, teachers and technological possibilities. Advances in technology have caused educators to look for new sources of knowledge development, which students could use inside and outside the classroom. Today’s sophisticated learning tools range from virtual environments to interactive multimedia resources, which can be called e-textbooks. Different types of new educational materials that go beyond printed books are now used to (...) support the academic curriculum, with the most interesting ones exemplified in this article to show their value in medical and life sciences education. Certain interesting attempts by Polish publishers at applying technology to support both self-paced and tutor-paced student learning in the medical profession and related areas are presented. The data was collected through a review of literature, discussions with e-learning specialists and medical students, as well as an analysis of examples of good practices. The article also discusses the results of a countrywide survey on the use of e-textbooks to enhance medical education. The research investigates the targeted academic staff’s attitudes towards the use of e-textbooks, the limitations of their implementation, and the character of e-resources currently used by Polish higher education medical institutions.

Playing fields are “spaces where the communitas suspends its everyday life and structures” and “The internal logic of sporting games is connected to values from the social context”, Playing fields: Power, practice, and passion in sport, 127–144. Reno: University of Nevada Press). But what about the space in between? What kind of semiotics organisation can be detected in the membrane between player and liminal space where spectators are not allowed yet specific characters needed to carry out an event? We can (...) therefore identify a liminality that can be connected either to the controlled or the wild playing field and depending on which of the two is the case can be analysed according to the degree of regulated system of signs which they produce. This implies different pathways and rituals: as matches are played, a variety of bodily activities may be taking place concurrently. Furthermore, it is inevitable that these activities attract the attention of the audience or alternately lead a player to interact with a non-player. In this article, I will first try to identify certain semiotics features, especially connected to Eco’s Peircian concept of Encyclopedia, that characterize the status of liminal space around the playing field. Then I will focus on liminality in soccer, investigating what kinds of interaction exist outside the playing area. (shrink)

This essay examines the response of Habermas and Giddens to postmodern criticisms of modernity. Although Giddens and Habermas recognize that the "totalizing critique" of poststructuralism lacks a convincing analysis of social interaction, neither of their perspectives adequately addresses the postmodern themes of aesthetics, play, and cultural memory. Giddens and Habermas believe that these dimensions of social life are important; yet they remain underdeveloped in their approaches. This essay explores the theoretical consequences of aesthetics, play, and cultural traditions for social (...) theory, drawing on the pragmatists, the psychoanalyst Winnicott, and early critical theory. The aesthetic and playful moments of experience must be recast in terms of social theory to avoid the solipsism so often characteristic of postmodernism. The essay ends by suggesting how the theories of Habermas and Giddens could benefit by a closer consideration of these issues. (shrink)

It is claimed that certain processes of individual behaviour and of interaction between individuals run parallel. Such parallels are seen along three axes: antagonism-coordination, constriction-expansion and neutral-play-like.Characteristics of ritualized behaviour and play are analysed and the two categories of behaviour are compared in detail. They are shown to differ largely in degree of expansion. They also differ along the antagonism-coordination axis. Both are play-like.

This article explores forms of haptic sociality in interspecies interaction. Data examined are taken from a corpus of equine assisted therapy sessions, in Finland and France. During these sessions, therapists invite clients to pay close attention to the horse’s behavioral displays of comfort or discomfort and to react accordingly. In this way, the horse is regarded as a living, sentient creature, whose body has haptic and kinesthetic properties, resulting in socialization practices that cultivate forms of care. The study discusses (...) Merleau-Ponty’s concept of “esthesiologic body”, in light of analytical instances, draws on contemporary re-examinations of phenomenological notions (such as intersubjectivity and intercorporeality) by ethnomethodologists and analysts of social interaction, and proposes to respecify them in the particular context of human–animal interactions. The argument is inspired by a conversation analytic approach, sensitive to the orderly character of social actions. Two formats, displaying diverse ways in which participants interact with the horse as an _esthesiologic_ body, are examined in detail. The analysis shows the fundamental role played by touch and haptic practices in the practical accomplishment of intercorporeality. (shrink)
